Manufacturer PCN Access Guide

How to Receive PCNs From Major Component Manufacturers

Product change notices are distributed differently by every manufacturer. Some provide public archives, some require registered accounts, and others notify only customers with an established purchasing relationship.

Use this guide to understand how major manufacturers distribute PCNs, what steps your team should take, and how notices can be processed through PCNshark.

Reviewed by the PCNshark teamLast reviewed June 25, 2026

Why is receiving manufacturer PCNs so difficult?

There is no universal system for receiving electronic component product change notices.

Some manufacturers maintain public archives. Others require users to create an account, register products, subscribe to specific part families, or establish a purchasing relationship. In many cases, notices are sent through authorized distributors rather than directly from the manufacturer.

As a result, hardware teams often depend on a combination of supplier portals, distributor emails, shared inboxes, PDF uploads, and internal spreadsheets. PCNshark helps centralize the notices your team receives, extract important information, match affected parts against BOMs, and track follow-up.

How major manufacturers distribute PCNs, and how PCNshark ingests them
Manufacturer	Public archive	Subscription	Account	Customer-specific	Distributor	PCNshark intake	Last verified
Altera	Yes - public collection of PCNs, PDNs, and ADVs for Altera FPGA/eASIC/Enpirion devices on altera.com/quality (mirrored on Intel's Resource & Documentation Center)	Yes - opt in via My Intel account: 'Follow this collection,' then enable email under My Intel Dashboard / Inbox Settings; a separate weekly Customer Notifications email subscription is also offered	No account needed to view/download notices; a free My Intel / Developer Zone Standard Registration account IS required to 'Follow this collection' and receive email alerts	Broadcast - notices are published to a public collection and emailed to all subscribers/followers, not sent only to affected customers (though Altera also notifies direct customers per JEDEC procedure)	Yes - PCN/PDN/ADV PDFs are also distributed through authorized distributors (DISTY-flagged documents are hosted by Mouser, Digi-Key, etc.), but the canonical archive is on Altera/Intel's own domain	Email + PDF upload	June 25, 2026
AMD	Yes - searchable Customer Notices archive at docs.amd.com (reached via xilinx.com/support/documentation-navigation/customer-notices.html, which redirects to a filtered docs.amd.com search); individual XCN/XDN PDFs are publicly downloadable with no login	Yes - per the standard notice boilerplate: 'AMD Customer Notifications (XCNs, XDNs, and Quality Alerts) can be delivered via e-mail alerts sent by the Support website... Register today and personalize your Documentation and Design Advisory Alerts area' (sign-up via Answer Record 18683)	To view notices: No (PDFs retrieved publicly). To receive e-mail alerts: Yes - must register on the AMD/Xilinx Support website and personalize alert preferences	Broadcast/published - notices are public documents anyone can read; affected customers are additionally directed to their AMD Sales Representative for last-time-buy forecasts and orders. Not a closed affected-customers-only model	Not clearly documented as the notification channel - notices direct customers to 'your local AMD Sales representative' for LTB/LTS questions and forecasts; distributors are not cited as the source of the notices	Email + PDF upload	June 25, 2026
Analog Devices	Per-product View PCN access + direct PDF links; no top-level searchable PCN/PDN archive found	Email subscription available (weekly myAnalog notifications via registered email)	No account to view per-product PCNs; myAnalog account required to subscribe/manage notifications	Also broadcast via myAnalog subscriptions; documents publicly viewable (not limited to purchasing relationship)	Authorized distributors also forward notices to their customers (per J-STD-046 framework ADI follows)	Email + PDF upload	June 25, 2026
AOS	No public searchable archive on aosmd.com; the quality/pcn page exposes only a 'PCN Account Sign In' portal, no browsable PCN/EOL list	Not clearly documented; AOS's own pages show no open email-alert sign-up form. PCNs are pushed directly to affected customers (delivery channel not specified on-site)	Yes to view/acknowledge via the portal — a 'PCN Account Sign In' (registered users) is required; no public viewing of notices on the site	Customer-specific — per AOS PCN CN-00477A, the notice covers 'products that you have purchased within the last two years', i.e. directed to affected/purchasing customers rather than a public broadcast	Not documented on AOS's own domain; PCN routing references 'your local AOS Sales Representative.' (Distributors such as DigiKey do republish AOS PCN PDFs, but that is third-party, not AOS's own channel)	Email + PDF upload	June 25, 2026
Broadcom	Yes - individual semiconductor PCN/PDN documents are hosted publicly on docs.broadcom.com (docSAFE) and open without login via direct URL or site search; however no single browsable PCN index/listing page was found	Not clearly documented for semiconductor PCNs - the documented email/proactive-notification subscription on support.broadcom.com applies to software products only; hardware PCN/PDN distribution is handled via direct customer/sales-channel notification per JEDEC, not a public self-serve email signup	No account required to view/download the public PCN/PDN PDFs on docs.broadcom.com; a Broadcom account is only relevant for the (software-only) support-portal notification settings and for entitled downloads	Direct customers and distributors of an affected part are notified directly (JESD46-style), while the resulting PCN/PDN documents are also posted publicly on docs.broadcom.com - effectively both targeted notification and public broadcast of the document	Yes - PCNs/PDNs surface through the distribution channel (e.g. notices also mirrored by Mouser); customers are directed to their Broadcom sales office or distributor for acknowledgment and last-time-buy orders	Email + PDF upload	June 25, 2026
Delta	Yes - public PCN/Product Notice archive at psu.deltaww.com/en/product-notice (no login); separate EOL archive under Tech Support > EOL; DC/DC & AC/DC module EOL page at deltaww.com/en-US/products/ctmPages/EOL-notes	Not clearly documented as a PCN/EOL-specific alert - only a general newsletter ('Be the first to hear about new events, news and products') was found; no dedicated PCN email-subscription confirmed	No - notices and EOL/PDN PDFs are publicly viewable without an account or login	Not clearly documented - notices are published as broadcast PCNs/EOLs on the public archive; whether affected customers also receive individual/direct notices is not stated on the pages reviewed	Not clearly documented - Delta PCN/PDN PDFs also appear on distributor sites (e.g. Mouser) but the official pages reviewed do not describe a distributor-mediated notification process	Email + PDF upload	June 25, 2026
Diodes	Yes - public PCN archive at diodes.com/quality/product-change-notices, no login required; individual PCN PDFs are directly downloadable from diodes.com/assets/PCN-Files/	Yes - free 'PCN E-mail alerts' subscription form at diodes.com/quality/product-change-notices/pcn-notification-email-alerts delivers PCNs to your inbox as they are released	No - viewing and downloading PCNs requires no account; subscribing to email alerts only requires submitting an email form, not a customer login	Broadcast - PCNs are posted publicly to the archive and pushed to all email-alert subscribers; the 30-day no-objection-equals-approval clause is standard boilerplate applied broadly, not a private per-customer notice	Diodes' PCNs are also redistributed by authorized distributors (e.g., Digi-Key, Mouser, Future, Anglia host copies), but the authoritative source and subscription are on diodes.com directly	Email + PDF upload	June 25, 2026
Epson	Yes — public, no-login Discontinued Products archive at epsondevice.com/crystal/en/products/discon/, browsable by product family with a keyword search box	Not clearly documented — no self-serve email-alert sign-up found on Epson's domain; notices direct customers to contact their local Epson device sales office	No — viewing and downloading notices/PDFs requires no login or account	Broadcast — notices are addressed generically ('Dear Valued Customer') and published publicly, not limited to affected customers	Distributors mirror the same notices (e.g. Epson EOL PDFs appear in the Mouser PCN library), but the primary/authoritative source is Epson's own epsondevice.com domain	Email + PDF upload	June 25, 2026
Flex Power Modules	Yes - public, login-free PDN archive at flex.com/products/power-modules/product-discontinuation-notices, also reachable via the Downloads & Resources page; individual PDNs are PDFs on the same domain	Indirect - a general email newsletter (flex.com/subscribe) and a 'new product notifications' news section exist for product news, but the FAQ does not document an email alert specifically for PCN/PDN/EOL; proactive PCN/PDN notification is routed through Channel Partners to affected customers	No - PDN archive and individual PDN documents are publicly viewable without any login or account	Customer-specific via partners - FAQ states PCN/PDN are shared with Channel Partners 'who will feed the information down to affected customers that have been active typically within the previous three years or so,' while the PDN archive itself is a public broadcast	Central - Flex sells through a 'global network of channel partners and representatives'; PCN/PDN notifications are explicitly distributed via Channel Partners, and RMAs/lifecycle questions are also routed through the originally-sourced channel/partner	Email + PDF upload	June 25, 2026
Infineon	Policy/process page only	Not clearly documented (myInfineon profile offers interest/newsletter subscriptions; a dedicated PCN/PDN email subscription is not clearly documented)	Account required to download (login needed for legacy Cypress PCN system; viewing-without-account for full portfolio not clearly documented)	Primarily customer-specific (Infineon states it informs the affected customers via PCN)	Distributor dependent (authorized distributors maintain their own PCN search/forwarding, e.g. Avnet/EBV; explicit forwarding obligation on Infineon's own domain not clearly documented)	Email + PDF upload	June 25, 2026
Intel	Yes - the RDC 'Product Change Notifications' collection houses PCN/PDN/PSN/ESUN and can be browsed and searched anonymously (public content); some content is restricted and requires sign-in/CNDA	Yes - email alerts are delivered via RDC 'Bookmark notifications' configured under My Intel Inbox Settings; a support article also references a weekly Customer Notifications subscription for PCN/PDN/FPGA advisories	No account to view/search/download public notices; a free My Intel/RDC account is required to set up email (bookmark) notifications, and Standard/Premier access (Premier needs CNDA) is required to see restricted content	Broadcast - notices are published to the public RDC archive for all users (Intel's notification process follows JEDEC J-STD-046 / J-STD-048); direct customer/distributor notification also occurs but the archive itself is general broadcast	Not required for access - Intel publishes notices directly on its own domain; distributors (e.g., Digi-Key/Mouser) also rehost Intel PCN/PDN PDFs, but the authoritative source is Intel's RDC	Email + PDF upload	June 25, 2026
ISSI	No public searchable PCN/PDN archive found on issi.com; the quality page describes a customer-directed PCN process, not an archive. Individual PCNs surface only on third-party distributor sites.	Not clearly documented	No account needed to read the quality-process page. ISSI operates an authenticated WorkFlow portal (portal-workflow.issi.com / workflow.issi.com) that requires sign-in; its role in PCN distribution is not clearly documented.	ISSI states notifications are 'sent out to customers via ISSI's PCN process,' implying a direct push to customers/affected accounts rather than a public broadcast; whether all customers or only affected ones receive each notice is not clearly documented. PCN PDFs are marked 'Confidential.'	Strong in practice: ISSI PCN/EOL documents are publicly available primarily through authorized distributors (Mouser, Digi-Key) rather than issi.com. ISSI maintains an authorized distributor network.	Email + PDF upload	June 25, 2026
Kingston	Yes — per-part PCN pages (kingston.com/en/memory/search/pcn?partId=<MPN>) and PCN PDFs hosted on media.kingston.com/pcn/ are publicly accessible and indexed; no login wall observed	Yes — the PCN Preferences page (kingston.com/en/support/pcn/subscribe) offers opt-in email notifications for Kingston part-number changes	Viewing/looking up PCNs by part number does NOT require an account; whether the email subscription on the PCN Preferences page requires a Kingston account vs. just an email address is Not clearly documented (page body blocked to automated fetch)	Broadcast / self-service — anyone can subscribe via the public Preferences page and PCN documents are public; notices are not limited to pre-existing affected customers	Not clearly documented — Kingston publishes PCNs directly on its own domain and via direct subscription; no official statement found that distributors are the required notification channel	Email + PDF upload	June 25, 2026
Kioxia	No public PCN/PDN archive for business/OEM parts on kioxia.com; the only public searchable notice archive (apac.kioxia.com important-notices / eol-products) is for personal/consumer products and covers software, security and end-of-support items, not industrial PCN/PDN	No documented self-serve PCN email-subscription. Kioxia sends product-update/transactional/warranty emails to registered users and marketing newsletters (with opt-out); industrial change notices reach customers through the direct customer/sales relationship	No account to view consumer notices (public); industrial PCN/PDN are delivered directly to customers via the Sales Department / Change Control Web System rather than a self-serve viewable page	Customer-specific: per the Quality Guidelines, PCNs are issued through Sales to affected customers and require customer approval/acknowledgment in advance for significant changes (not a broadcast public notice)	Yes: Kioxia sells through authorized distributors/representatives (sales lookup directory), and distributors (e.g., Apacer, ATP, TDK, Viking) issue their own downstream PCNs cascading Kioxia NAND changes; third-party distributor sites also host Kioxia PDN PDFs	Email + PDF upload	June 25, 2026
Lattice Semiconductor	Public PCN web page with downloadable notices	Email PCN alerts available via account registration	No account to view notices; account required to subscribe	Broadcast to subscribers/customers, not purchase-relationship gated	Not clearly documented	Email + PDF upload	June 25, 2026

Marvell	No public PCN archive — the public Document Library (marvell.com/support/doc-library.html) lists no PCN/PDN/EOL document type; PCNs live only in the login-gated Customer Portal	Yes — the portal Notification system plus bell/Notifications widget; registration/activation and alerts are email-driven, configurable in Settings	Yes — registration is required to view, and a valid NDA must be on file ('Marvell validates customer NDA'; 'access to all Marvell documentation requires that you be under a current NDA')	Access-gated to NDA customers and to the product folders they are granted (My Products = NDA-protected assets; My Projects = 'customer specific folders'); not a public broadcast	Not clearly documented	Email + PDF upload	June 25, 2026
MCC	Yes - public 'ECN/PCN List' at mccsemi.com/ECNPCN/List plus PCN/EOL PDFs under mccsemi.com/pdf/ecn/ and /pdf/eol/	Not clearly documented - no email-subscription/sign-up form was found on the official domain; MCC instead pushes notices to customers via local sales representatives	No account required to view notices - PCN/EOL PDFs and the ECN/PCN List are publicly reachable on the open domain (no login wall observed)	Broadcast - PCNs use a generic 'Dear Customer'/'Dear Valued MCC Customers' salutation from the 'MCC PCN Team', not addressed to individual affected customers	Distributors mirror MCC PCNs (e.g. Mouser, Digi-Key host the same PDFs), and MCC routes acknowledgement through 'your local sales representative'; the canonical archive is on MCC's own domain	Email + PDF upload	June 25, 2026
Microchip	Public searchable archive	Email subscription available (daily or weekly)	No account to view; account required to subscribe	Broadcast to all registered subscribers; custom auto/PPAP routed to email on file	Not clearly documented	Email + PDF upload	June 25, 2026

Monolithic Power Systems	No public searchable PCN/PDN archive documented on the MPS domain; only a downloadable Product Obsolescence Policy document is published	Not clearly documented as a self-serve PCN email subscription; MPS pushes PDNs directly to affected customers/distributors via the account relationship (a general marketing newsletter exists but is not a change-notice channel)	Policy document is public (no login); a myMPS+ account exists for site features but is not documented as a PCN-notification channel	Customer-specific: MPS notifies sales force, distributors, and customers who purchased the product within the past 24 months (84 months for Automotive parts)	Yes — distributors are explicitly named recipients of PDNs alongside direct customers and the MPS sales force	Email + PDF upload	June 25, 2026
Nexperia	No login-free public PCN archive on nexperia.com; the full archive (PCN/CIN/DN/RN) lives behind the My Nexperia login (PCN list/preferences pages redirect to login.nexperia.com). Individual notice PDFs are publicly mirrored by distributors (Mouser/TTI/Digi-Key/Farnell), not on Nexperia's own domain.	Yes. CN emails are sent (from pcn@nexperia.com) to recipients who are 'a designated contact or subscribed to Nexperia Quality Notifications'; cadence/content controlled by CN preferences in My Nexperia (/my/pcn/my-preferences).	Yes for viewing the on-domain archive and for managing email subscriptions — both /my/pcn/details and /my/pcn/my-preferences redirect to the login.nexperia.com OpenID login wall. Viewing individual notice PDFs via distributors needs no Nexperia account.	Hybrid: emails are pushed to designated contacts / quality-notification subscribers, and the portal shows the CNs 'available to you' (i.e., scoped to the account's products). Acknowledgement is expected per JEDEC J-STD-046, and lack of acknowledgement constitutes acceptance of the change.	Yes. Notice PDFs are broadly distributed/mirrored by authorized distributors (Mouser, TTI, Digi-Key, Farnell). EOL/excess and last-time-buy fulfillment is handled via the Rochester Electronics partnership; channel partners are an additional notification path beyond direct designated contacts.	Email + PDF upload	June 25, 2026
Niko Semiconductor	Yes - a public EOL/discontinuance archive at niko-sem.com (EOL menu, portal_d747.php) listing all EOL notices with downloadable PDF letters; no login needed (verified by direct fetch)	Not clearly documented - no email-subscription, RSS, or 'notify me' mechanism for EOL/PCN found on the official site	No - both viewing the EOL table and downloading the EOL Letter PDFs work without any login or account (confirmed: EOL letter PDF downloaded HTTP 200, no auth); a generic 'member login' template block exists site-wide but does not gate EOL access	Broadcast - EOL notices are published in a public archive open to anyone, not gated to only affected customers; individual customer outreach (e.g. via agents/sales) is not documented on the site	Likely - NIKO-SEM lists an Agent / Business Service Office (distributor/sales) network under Contact, but the EOL archive itself is published directly by the manufacturer; distributor role in EOL delivery is Not clearly documented	Email + PDF upload	June 25, 2026
Nuvoton	Yes - public no-login EOL product listing at nuvoton.com/product-related-information/eol/ with discontinued parts, notification/last-order/last-shipment dates and recommended replacements; a downloadable EOL-list PDF is also published. No separate public PCN (process/spec-change) archive found on the domain.	Not clearly documented - no PCN/EOL email subscription is documented on Nuvoton's site. myNuvoton offers document-update tracking and an e-paper news subscription, but neither is described as a PCN/EOL alert.	No - EOL listings, Product Longevity Program, and Quality Documents are publicly viewable without login. A myNuvoton account exists but is not required to view EOL/obsolescence info.	Not clearly documented - Nuvoton does not state on its own pages whether EOL/change notices go only to affected customers or are broadcast; the public EOL page serves as a broadcast-style listing.	Partial - Nuvoton's own pages do not document a distributor notification flow, but individual Nuvoton EOL/obsolescence notice PDFs are hosted by distributors such as DigiKey, and the site links to Worldwide Rep & Disti for purchasing.	Email + PDF upload	June 25, 2026

Renesas	Public searchable archive	Email subscription available via My Renesas / Document Update Notification	No account to view notices; account required to subscribe	Both: notifies affected customers directly and posts notices publicly	Distributors/buyers responsible for forwarding notices to third parties	Email + PDF upload	June 25, 2026
Richtek	No public PCN/PDN archive found on richtek.com (the change-management page is a process description, not an archive; the only public PCN PDFs are hosted by third-party distributors)	PCNs are sent directly to eligible customers; a separate MyRichtek 'Datasheet Alert' emails users when a datasheet is updated, but it is not documented as covering PCN/PDN/EOL	A free MyRichtek account/login is required for the related Datasheet Alert and newsletter features; PCN issuance itself is a direct customer notification (no account documented as required to receive a PCN)	Customer-specific: PCNs go to customers who made purchases within the past ~2 years, not a public broadcast	Not clearly documented (the official change-management page does not mention distributors in the notification flow)	Email + PDF upload	June 25, 2026
ROHM	No public searchable PCN/PDN document archive on rohm.com; the supply_status page is informational (lifecycle definitions) only.

Semtech	No — no public PCN/EOL archive found on semtech.com; historical notices surface only via third-party distributors (Mouser, Digi-Key)	Yes — the Quality Manual states notifications are 'sent to the customer using e-mail,' but only to customers under a notification agreement (not a self-serve public subscription)	Notifications are delivered directly by email under a notification agreement; the on-site document portal (mySemtech / Document Portal) is login-gated and requires registration/approval to access private documents	Customer-specific — PCNs go to customers 'who have entered into a notification agreement'; EOLs go to customers who purchased the affected product within the previous 24 months and maintain a notification agreement	Not clearly documented as an official channel; in practice Semtech PCN/EOL PDFs are widely hosted by distributors (Mouser, Digi-Key), but this is not described in Semtech's own notification policy	Email + PDF upload	June 25, 2026

AlteraPCN archive · verified Jun 25, 2026＋

Altera (the FPGA company, formerly Intel Programmable Solutions Group / originally Altera Corporation, now a standalone company) maintains an official, publicly viewable collection of Product Change Notifications (PCN), Product Discontinuance Notifications (PDN), and Customer Advisories (ADV) for Altera FPGAs, eASIC, and Enpirion devices at altera.com/quality/pcn-pdn-adv, mirrored on Intel's support/Resource & Documentation Center. The process follows JEDEC J-STD-046 (process/product changes) and J-STD-048 (product discontinuance); email alerts require a free My Intel / Developer Zone account and are sent for the whole collection (broadcast), not per individual part number.

How notifications work

Altera publishes PCNs (process/product changes), PDNs (product discontinuance / EOL with last-order and last-ship dates), and ADVs (customer advisories) covering Altera FPGAs, eASIC, and Enpirion devices.
The notification process adheres to JEDEC J-STD-046 (customer notification of product/process changes) and J-STD-048 (product discontinuance notification).
All notices are gathered in a public collection at altera.com/quality/pcn-pdn-adv (also on Intel's support and Resource & Documentation Center), which can be searched, viewed, and downloaded as PDFs without an account.
To get alerts, create a free My Intel / Developer Zone account, click 'Follow this collection,' then enable email delivery under My Intel Dashboard > Inbox Settings; a separate weekly Customer Notifications email subscription is also available.
Email alerts cover the whole followed collection (broadcast to all subscribers) rather than a single negotiated part number; direct customers are also notified per Altera's JEDEC-aligned procedure.
Notices are additionally pushed to authorized distributors (DISTY-flagged documents appear on Mouser, Digi-Key, etc.) for downstream customer reach.

What your team should do

1.Bookmark and periodically check the official archive at https://www.altera.com/quality/pcn-pdn-adv (or the Intel mirror) to review current and historical PCNs, PDNs, and ADVs.
2.Create a free My Intel / Developer Zone account, open the PCN/PDN/ADV collection, click 'Follow this collection,' and enable email under My Intel Dashboard > Inbox Settings so changes reach your inbox.
3.Also opt into the weekly Customer Notifications email subscription for a recurring digest of PCN/PDN/ADV activity.
4.Because alerts are collection-wide (not per part), map your affected Altera/eASIC/Enpirion MPNs internally and filter incoming notices against your BOM rather than relying on part-level subscriptions.
5.On any PDN, capture the last-time-buy (last order acceptance) and last-ship dates and plan last-time-buys / qualification of alternates accordingly.
6.Confirm your authorized distributor (e.g., the franchised disty on your account) is also forwarding Altera DISTY notices as a secondary channel.

Access summary

Public archive: Yes - public collection of PCNs, PDNs, and ADVs for Altera FPGA/eASIC/Enpirion devices on altera.com/quality (mirrored on Intel's Resource & Documentation Center)
Searchable historical notices: Yes - the Intel/Altera PCN collection lets users search, view, and download current and historical PCN/PDN/PSN/ESU notices; older Altera notices (e.g. PDN9601 from 1996, PDN1208 from 2012) are still retrievable
Account required: No account needed to view/download notices; a free My Intel / Developer Zone Standard Registration account IS required to 'Follow this collection' and receive email alerts
Email notification: Yes - opt in via My Intel account: 'Follow this collection,' then enable email under My Intel Dashboard / Inbox Settings; a separate weekly Customer Notifications email subscription is also offered
Part-number subscription: Not clearly documented - subscription is by following the FPGA/eASIC/Enpirion notification collection (broadcast), not documented as a per-part-number or single-product-family alert
Customer-specific notification: Broadcast - notices are published to a public collection and emailed to all subscribers/followers, not sent only to affected customers (though Altera also notifies direct customers per JEDEC procedure)
Distributor involvement: Yes - PCN/PDN/ADV PDFs are also distributed through authorized distributors (DISTY-flagged documents are hosted by Mouser, Digi-Key, etc.), but the canonical archive is on Altera/Intel's own domain

AMDPCN archive · verified Jun 25, 2026＋

AMD (Advanced Micro Devices) publishes Customer Notifications for its Adaptive Computing / FPGA line (formerly Xilinx) as numbered, publicly downloadable PDFs at docs.amd.com — XCN = Customer Notices including Product Discontinuation Notices, plus XDNs and Quality Alerts. The customer-notices archive (xilinx.com/support/documentation-navigation/customer-notices.html, which 301-redirects to a searchable docs.amd.com document filter) lets anyone browse/search historical notices without an account; e-mail alerts are opt-in via registering on the AMD/Xilinx Support site and configuring "Documentation and Design Advisory Alerts."

How notifications work

AMD's Adaptive Computing / FPGA business (formerly Xilinx) issues numbered Customer Notices: XCNs (which include Product Discontinuation Notices), XDNs, and Quality Alerts, published as PDFs on docs.amd.com.
Each Product Discontinuation Notice states the affected standard part numbers and SCDs, replacement parts (or 'No direct replacement'), and Last-Time-Buy (LTB) and Last-Time-Ship (LTS) dates; open orders become Non-Cancellable/Non-Returnable (NCNR) after a stated date.
The notice boilerplate states verbatim: 'AMD Customer Notifications (XCNs, XDNs, and Quality Alerts) can be delivered via e-mail alerts sent by the Support website. Register today and personalize your Documentation and Design Advisory Alerts area to include Customer Notifications.'
E-mail alerts are opt-in: you register on the AMD/Xilinx Support site and configure alerts for specific products/publications (data sheets, errata, app notes, notices). Sign-up steps are in Xilinx Answer Record 18683.
Notices are public documents browsable/searchable in the docs.amd.com Customer Notices archive (no login to view); they also instruct affected customers to contact their local AMD Sales Representative for LTB forecasts and order placement.
Older Xilinx.com notice and quality URLs 301-redirect to amd.com / docs.amd.com, confirming the official domain consolidation.

What your team should do

1.Register a (free) account on the AMD/Xilinx Adaptive Computing Support site and enable e-mail alerts under 'Documentation and Design Advisory Alerts,' selecting the specific FPGA/SoC/Alveo products you use (see Xilinx Answer Record 18683 for steps).
2.Bookmark and periodically search the public Customer Notices archive at docs.amd.com (start from xilinx.com/support/documentation-navigation/customer-notices.html) to catch XCNs/XDNs even before alert e-mails arrive.
3.On each Product Discontinuation Notice, record the affected MPNs/SCDs, the Last-Time-Buy and Last-Time-Ship dates, the NCNR cutoff, and any listed replacement part numbers.
4.For affected lines, contact your local AMD Sales Representative early to submit a last-time-buy forecast (AMD asks for forecasts when LTB demand exceeds the current run rate; orders are first-come, first-served and NCNR).
5.Map AMD XCN/XDN part numbers against your BOMs and flag matches to procurement/engineering so last-time-buy and requalification can start before the LTB date.
6.Note that AMD's CPU/GPU (non-Adaptive) lines may use separate channels; confirm coverage for any non-FPGA AMD parts directly with AMD if relevant.

Access summary

Public archive: Yes - searchable Customer Notices archive at docs.amd.com (reached via xilinx.com/support/documentation-navigation/customer-notices.html, which redirects to a filtered docs.amd.com search); individual XCN/XDN PDFs are publicly downloadable with no login
Searchable historical notices: Yes - notices are numbered (e.g. XCN08011, XCN10016, XCN23004, XCN24003) spanning many years; notices state they should be used 'in conjunction with previous discontinuance notices which can be found at AMD.com/Xilinx.com'
Account required: To view notices: No (PDFs retrieved publicly). To receive e-mail alerts: Yes - must register on the AMD/Xilinx Support website and personalize alert preferences
Email notification: Yes - per the standard notice boilerplate: 'AMD Customer Notifications (XCNs, XDNs, and Quality Alerts) can be delivered via e-mail alerts sent by the Support website... Register today and personalize your Documentation and Design Advisory Alerts area' (sign-up via Answer Record 18683)
Part-number subscription: Yes - Support alerts include 'the ability to receive alerts for new and updated information about specific products' via the Documentation and Design Advisory Alerts area; product/product-family granularity. Strict single-MPN-only subscription not explicitly documented
Customer-specific notification: Broadcast/published - notices are public documents anyone can read; affected customers are additionally directed to their AMD Sales Representative for last-time-buy forecasts and orders. Not a closed affected-customers-only model
Distributor involvement: Not clearly documented as the notification channel - notices direct customers to 'your local AMD Sales representative' for LTB/LTS questions and forecasts; distributors are not cited as the source of the notices

Analog DevicesNotification-policy page · verified Jun 25, 2026＋

Analog Devices distributes PCNs and PDNs primarily through its myAnalog account portal: customers create a free myAnalog profile, save the products/models they care about, and then receive PCN/PDN notices via weekly email plus in-portal updates. Individual PCN/PDN documents are also reachable without login per-product (product page → Pricing, Packaging & Availability → "View PCN") and as directly-linkable PDFs, but ADI does not appear to expose a single top-level publicly searchable archive that lists/filters all PCNs across the catalog.

How notifications work

ADI publishes Product Change Notices (PCN) and Product Discontinuance Notices (PDN); its PCN policy complies with JEDEC J-STD-046 and PDN policy with J-STD-048, with PCNs published to customers at least 90 days before implementation/shipment of changed material.
The primary subscription mechanism is a free myAnalog account: users save products/models and toggle PCN/PDN notifications on the 'Notifications' tab; subscribed notices are emailed to the registration address (weekly cadence, format/language/unsubscribe configurable) and shown on the myAnalog home page.
You can subscribe by specific part/model: from a product's PCN page click 'Save to myAnalog', or in myAnalog go to Preferences → PCNs and type the Product or Model number into 'Add More Products/Models' (account + login required).
Per-product viewing requires no login: on a product page's Pricing, Packaging & Availability section, click 'View PCN' to open a pop-up listing that model's PCNs/PDNs (most recent on top), expandable to the PCN Form, affected Material Report, and supporting files; PCNs also appear under the product page Documentation section.
Individual PCN/PDN documents are also published as directly accessible PDFs under analog.com/media/.../PCN/ (e.g., ADI_PCN_YY_NNNN and ADI_PDN_YY_NNNN forms), viewable without an account.
Under the J-STD-046 framework ADI follows, the 90-day window allows authorized distributors to forward the notice to their own customers of the affected product; customers are expected to acknowledge a PCN within 30 days (non-acknowledgment within 30 days is treated as acceptance).

What your team should do

1.Create a free myAnalog account (my.analog.com) and have the team member who owns supply-chain monitoring log in, since subscribing to and managing PCN/PDN notifications requires an account.
2.Add the exact ADI part/model numbers you use: either click 'Save to myAnalog' from each product's PCN page, or in myAnalog go to Preferences → PCNs and enter the Product/Model numbers under 'Add More Products/Models'.
3.Configure the weekly email notification (format, language) so PCN/PDN alerts go to a monitored mailbox; consider a shared/distribution mailbox as the registration email so notices aren't tied to one person.
4.For ad-hoc checks without logging in, open the specific product page, go to Pricing, Packaging & Availability, and click 'View PCN' to see that model's full PCN/PDN list and download the PCN Form and affected Material Report.
5.Confirm with your authorized ADI distributor(s) that they will also forward PCNs/PDNs for your purchased parts, since the J-STD-046 process relies on distributors relaying notices to their customers.
6.On receiving a PCN, act within the JEDEC windows: acknowledge within 30 days and request samples/additional information within 30 days, since non-acknowledgment is treated as acceptance, and use the 90-day lead time for qualification/last-time-buy decisions.

Access summary

Public archive: Per-product View PCN access + direct PDF links; no top-level searchable PCN/PDN archive found
Searchable historical notices: Per model the PCN pop-up lists all PCNs/PDNs newest-first; no catalog-wide searchable history found

AOSCustomer portal · verified Jun 25, 2026＋

Alpha & Omega Semiconductor (AOSMD) distributes Product Change Notifications through a customer-direct model: PCNs are sent to customers who purchased the affected products within the last two years (verified by AOS PCN document CN-00477A), and acknowledgement is handled through a registered-user "PCN Account Sign In" portal at aosmd.com/quality/pcn or by returning an Acknowledgement Form to a local AOS Sales Representative. AOS's own quality/pcn page exposes only the login portal — there is no publicly browsable/searchable PCN archive, no open email-alert subscription, and no part-number/family self-subscription visible on the public site.

How notifications work

PCNs are issued as 'Product/Process Change Notice' PDFs (e.g. CN-00477A) by AOS's Product & Test department, signed by the SVP of Quality.
Each PCN states it 'contains advance information about changes we are planning to make to products that you have purchased within the last two years' — notices are directed to customers who bought the affected parts, not broadcast publicly.
Customers are asked to 'acknowledge receipt of this PCN within 30 days by signing in at http://www.aosmd.com/quality/pcn or sending the enclosed Acknowledgement Form to your local AOS Sales Representative.'
'Lack of acknowledgement of the PCN within 30 days constitutes acceptance of the change.'
The aosmd.com/quality/pcn page provides only a registered-user 'PCN Account Sign In' portal (coolweb.aosmd.com); it does not present a public, searchable archive of past notices or an open email-subscription / part-number alert form.
Questions are routed to a local AOS Sales Representative via aosmd.com/contact.

What your team should do

1.Establish a direct relationship and named contact with your AOS Sales Representative (via aosmd.com/contact) — this is AOS's primary, documented PCN channel.
2.Request a PCN account / sign-in at aosmd.com/quality/pcn so your team can receive and acknowledge PCNs through AOS's registered-user portal.
3.Make sure AOS has the correct quality/SCM recipient on file, since PCNs are pushed to customers who purchased affected parts within the prior two years — keep your purchasing entity and contact current.
4.Track the 30-day acknowledgement window: review each PCN and respond, because non-acknowledgement is treated as acceptance of the change.
5.Ask your AOS rep directly whether email PCN alerts or part-number/family subscriptions are available, since these are not documented on the public site.
6.As a supplementary feed only, monitor authorized distributors (e.g. DigiKey/Mouser) who republish AOS PCN PDFs — but treat AOS's direct channel as authoritative, not the distributor copies.

Access summary

Public archive: No public searchable archive on aosmd.com; the quality/pcn page exposes only a 'PCN Account Sign In' portal, no browsable PCN/EOL list
Searchable historical notices: Not clearly documented; no public historical notice search visible (any history would sit behind the registered-user PCN portal at coolweb.aosmd.com, which is not publicly accessible)
Account required: Yes to view/acknowledge via the portal — a 'PCN Account Sign In' (registered users) is required; no public viewing of notices on the site
Email notification: Not clearly documented; AOS's own pages show no open email-alert sign-up form. PCNs are pushed directly to affected customers (delivery channel not specified on-site)
Part-number subscription: Not clearly documented; no part-number or product-family self-subscription mechanism is shown on the public site
Customer-specific notification: Customer-specific — per AOS PCN CN-00477A, the notice covers 'products that you have purchased within the last two years', i.e. directed to affected/purchasing customers rather than a public broadcast
Distributor involvement: Not documented on AOS's own domain; PCN routing references 'your local AOS Sales Representative.' (Distributors such as DigiKey do republish AOS PCN PDFs, but that is third-party, not AOS's own channel)

BroadcomCustomer portal · verified Jun 25, 2026＋

Broadcom publishes semiconductor Product/Process Change Notices (PCNs) and Product Discontinuance Notices (PDNs/EOL) as individual documents on its docSAFE document portal at docs.broadcom.com, following JEDEC JESD46 conventions (notify customers, ~30-day acknowledgment window with silence treated as acceptance, last-time-buy on discontinuances, contact via Broadcom sales). These hardware PCN/PDN PDFs are publicly reachable by direct URL and site search without login, but there is no single browsable PCN archive index and no self-service email/part-number subscription for semiconductor PCNs — Broadcom's account-based proactive-notification and product-lifecycle systems on support.broadcom.com cover only its software divisions (Symantec/VMware/CA/Carbon Black), not semiconductor components.

How notifications work

Broadcom issues semiconductor Product/Process Change Notices (PCNs) and Product Discontinuance Notices (PDNs/EOL) as individual documents posted on its docSAFE portal at docs.broadcom.com.
Notices follow JEDEC JESD46 conventions: affected customers are notified through Broadcom sales/distribution channels, and lack of acknowledgment within the stated window (typically ~30 days for PDNs) is treated as acceptance of the change.
PDNs/EOL notices specify last-time-buy (LTB) order requirements and dates; LTB orders are typically non-cancelable/non-returnable and orders after the LTB date are not accepted.
The published PCN/PDN PDFs on docs.broadcom.com are publicly accessible by direct URL and via web/site search without a login.
No single public, browsable, date-sortable PCN archive index was found on the Broadcom domain, and no self-service email or part-number subscription specifically for semiconductor PCNs was documented.
Broadcom's account-based proactive-notification system and product-lifecycle/EOL pages on support.broadcom.com cover its software divisions (Symantec/VMware/CA/Carbon Black) only — not semiconductor hardware components.

What your team should do

1.For each Broadcom (incl. legacy Avago, LSI, PLX, Brocade ASIC) MPN you use, identify your authorized distributor or Broadcom sales contact and confirm with them that your account is on the PCN/PDN distribution list for those parts — this is the primary, supplier-supported notification channel.
2.Periodically search docs.broadcom.com (and the supplier's support download search) by part number to retrieve any posted PCN/PDN/EOL documents, since there is no single browsable archive to monitor.
3.When a PCN/PDN is received, act within the stated acknowledgment window (commonly ~30 days) — silence is treated as acceptance under JEDEC JESD46.
4.On discontinuance (PDN/EOL) notices, evaluate and place last-time-buy orders before the LTB date; treat them as non-cancelable/non-returnable and plan inventory/redesign accordingly.
5.Capture each notice's affected part numbers and effective/LTB dates into your BOM/PCN tracking so the raw MPNs on your BOM are matched against the affected list.
6.Do not rely on Broadcom's support.broadcom.com proactive-notification subscription for hardware — it is software-only; instead lean on distributor PCN feeds plus periodic docs.broadcom.com checks.

Access summary

Public archive: Yes - individual semiconductor PCN/PDN documents are hosted publicly on docs.broadcom.com (docSAFE) and open without login via direct URL or site search; however no single browsable PCN index/listing page was found
Searchable historical notices: Partial - older PCNs/PDNs (e.g. PLX PDN 2011, PCNs back to 2006-2008) remain retrievable by direct URL and search engine, but there is no dedicated date-sortable historical archive UI on the supplier domain
Account required: No account required to view/download the public PCN/PDN PDFs on docs.broadcom.com; a Broadcom account is only relevant for the (software-only) support-portal notification settings and for entitled downloads
Email notification: Not clearly documented for semiconductor PCNs - the documented email/proactive-notification subscription on support.broadcom.com applies to software products only; hardware PCN/PDN distribution is handled via direct customer/sales-channel notification per JEDEC, not a public self-serve email signup
Part-number subscription: Not clearly documented - no self-service part-number or product-family PCN subscription was found on the official semiconductor domain
Customer-specific notification: Direct customers and distributors of an affected part are notified directly (JESD46-style), while the resulting PCN/PDN documents are also posted publicly on docs.broadcom.com - effectively both targeted notification and public broadcast of the document
Distributor involvement: Yes - PCNs/PDNs surface through the distribution channel (e.g. notices also mirrored by Mouser); customers are directed to their Broadcom sales office or distributor for acknowledgment and last-time-buy orders

DeltaPCN archive · verified Jun 25, 2026＋

Delta Electronics (power supply / power module business, deltaww.com) publishes Product Change Notices and End-of-Life notices through its own public website. The Delta PSU site hosts a filterable, paginated "Product Notice" archive at psu.deltaww.com/en/product-notice (56 numbered PCNs as of the visit, e.g. PCN-25-021, filterable by Industrial Power / Medical Power / LED Driver) plus a separate EOL section under Tech Support that lists discontinuance notices with Last Buy and Last Shipment dates, and downloadable PDN/EOL PDFs are hosted on filecenter.deltaww.com. No login is required to read any of these. There is no part-number-level subscription found — only a general marketing newsletter.

How notifications work

Delta publishes numbered Product Change Notices (e.g. PCN-23-001, PCN-25-021) in a public, login-free archive on the power-supply site at psu.deltaww.com/en/product-notice; the archive is paginated and filterable by category (All / Industrial Power / Medical Power / LED Driver) and showed 56 notices at the time of review.
End-of-Life / discontinuance notices are published separately under Tech Support > EOL on psu.deltaww.com and include Last Buy Date and Last Shipment Date (e.g. an LED Driver EOL with Last Buy Oct 2022 / Last Shipment Jul 2023).
Standard Power Module (DC/DC & AC/DC) EOL notices are listed on the main corporate site at deltaww.com/en-US/products/ctmPages/EOL-notes, with downloadable PDN/EOL PDFs hosted on filecenter.deltaww.com (e.g. 'Delta Electronics PDN 20240108.pdf').
Each notice is a downloadable PDF describing the affected product/series and the nature of the change (e.g. serial-number format change, certification/label updates, packaging changes, design upgrades, firmware updates, or discontinuation).
The only subscription mechanism found on the official site is a general newsletter signup ('Be the first to hear about new events, news and products'); no PCN/part-number-specific email alert was confirmed.

What your team should do

1.Bookmark and periodically poll the official Delta PSU Product Notice archive at https://psu.deltaww.com/en/product-notice and the EOL section (Tech Support > EOL) - both are public and require no login - and use the category filters (Industrial Power / Medical Power / LED Driver) to scope to your part families.
2.For DC/DC and AC/DC standard power modules, also monitor deltaww.com/en-US/products/ctmPages/EOL-notes and download the PDN/EOL PDFs from filecenter.deltaww.com for last-time-buy and last-ship dates.
3.Map your BOM's Delta MPNs/series to the affected products named in each PCN/EOL, and track the PCN/PDN numbers (e.g. PCN-25-021) and Last Buy / Last Shipment dates for LTB planning.
4.Because no reliable part-number subscription was confirmed, set up your own change-monitoring (scheduled re-checks of the archive pages) rather than relying solely on Delta email alerts; optionally subscribe to the general newsletter as a low-fidelity supplement.
5.For authoritative per-part status, last-time-buy quantities, or to confirm whether you'll receive direct notification as an affected customer, contact your Delta sales representative or the relevant Delta business-unit customer service directly - this is not documented as automatic on the public site.

Access summary

Each PCN is a downloadable PDF (hosted at diodes.com/assets/PCN-Files/) and includes contact and implementation dates, alert category and type, PCN number, title, impact, description of change, and the complete list of affected Diodes part numbers.
Customers can self-subscribe to free 'PCN E-mail alerts' via a form at diodes.com/quality/product-change-notices/pcn-notification-email-alerts; alerts are emailed as PCNs are released.
Standard PCN terms state that unless a Diodes sales representative is contacted in writing within 30 days of the notice, the described changes are considered approved.
EOL notices may include a last-time-buy / last-order-date and last-ship-date window where offered; Diodes reserves the right to obsolete products with no life-time-buy offer without further notification.
Authorized distributors (e.g., Digi-Key, Mouser, Future, Anglia) also redistribute Diodes PCNs, but diodes.com is the authoritative source.

What your team should do

1.Bookmark and periodically review the official archive at diodes.com/quality/product-change-notices, browsing by year to catch new PCNs and EOL notices affecting your Diodes part numbers.
2.Subscribe to Diodes' free PCN email alerts at diodes.com/quality/product-change-notices/pcn-notification-email-alerts so notices arrive in your inbox automatically.
3.When a relevant PCN/EOL is issued, act within the 30-day window - contact your Diodes sales representative or distributor in writing if you need to object, request samples, or arrange a last-time-buy.
4.For EOL parts, check the PCN for last-order and last-ship dates and place any life-time-buy orders before the deadline; assume parts with no LTB offer may go obsolete without further notice.
5.Cross-reference incoming PCNs against your BOM using the affected-part-number list in each PCN PDF, and keep distributor PCN feeds (Digi-Key/Mouser/etc.) as a secondary backstop to the direct subscription.

EpsonPCN archive · verified Jun 25, 2026＋

Epson's timing-device / semiconductor arm (Seiko Epson Corporation, Microdevices Operations, branded "Epson Crystal Device") publishes EOL/ECN notices publicly on its own domain epsondevice.com. There is a no-login, keyword-searchable "Discontinued Products" archive at /crystal/en/products/discon/ organized by product family, with individual dated, numbered notice PDFs (e.g. 20-027E, 24-009E_NRND, 25-006E/25-012E/25-013E) hosted under /crystal/en/techinfo/pdf/; the older path was literally named "pcn_ecn", confirming Epson's own PCN/ECN terminology. Notices are broadcast "Dear Valued Customer" letters (not customer-specific) that list affected part numbers, recommended alternatives, NRND/discontinued status, and last-time-buy / last-shipment dates, and direct questions to the local Epson device sales office. No self-serve email/RSS or part-number subscription mechanism was found on Epson's domain.

How notifications work

Epson Crystal Device (Seiko Epson Corporation, Microdevices Operations) issues numbered EOL/ECN notices (format NN-NNNE, e.g. 20-027E_Rev.4, 24-009E_NRND, 25-013E_EOL) as dated 'Dear Valued Customer' broadcast letters.
Notices are published as public PDFs under https://www.epsondevice.com/crystal/en/techinfo/pdf/ and surfaced through the public Discontinued Products archive at /crystal/en/products/discon/ (no login required).
Each notice lists affected product names and part numbers, recommended alternative products with migration notes, status (NRND vs Discontinued), and an EOL schedule with last-time-buy and last-shipment dates.
The Discontinued Products archive is browsable by product family (crystal units, oscillators/SPXO/TCXO/VCXO, RTC modules, gyro sensors, others) and includes a keyword search box (e.g. by part number).
Notices instruct customers to contact their local Epson device sales office for questions or additional information — no self-serve email/RSS subscription is offered on Epson's domain.
The same notices are also mirrored by distributors (e.g. the Mouser PCN library), which can serve as a secondary monitoring source.

What your team should do

1.Bookmark and periodically poll the public Discontinued Products archive at https://www.epsondevice.com/crystal/en/products/discon/ for your Epson timing-device / RTC / oscillator part numbers (no login needed).
2.For any affected part, open the linked notice PDF under /crystal/en/techinfo/pdf/ and capture the notice number, last-time-buy date, last-shipment date, and recommended replacement.
3.Because there is no confirmed email/RSS subscription on Epson's site, establish a recurring manual or scraped check of the discontinued-products list, or have PCNshark monitor those URLs.
4.Contact your local Epson device sales office (the channel the notices point to) to ask whether they can add you to a direct distribution list for future EOL/ECN notices.
5.Cross-check distributor PCN feeds (e.g. Mouser's Epson PCN library) as a redundant monitoring source, but treat epsondevice.com as the authoritative record.
6.When a notice cites a recommended alternative, note that Epson flags pinout/package/software differences (e.g. SPI 4-wire, terminal arrangement) — schedule a requalification rather than assuming a drop-in replacement.

Access summary

Public archive: Yes — public, no-login Discontinued Products archive at epsondevice.com/crystal/en/products/discon/, browsable by product family with a keyword search box
Searchable historical notices: Yes — historical EOL/ECN notice PDFs from multiple years (2020, 2022, 2024, 2025 confirmed) are openly hosted under /crystal/en/techinfo/pdf/ and reachable from the discontinued-products listing
Account required: No — viewing and downloading notices/PDFs requires no login or account
Email notification: Not clearly documented — no self-serve email-alert sign-up found on Epson's domain; notices direct customers to contact their local Epson device sales office
Part-number subscription: Not clearly documented — no per-part-number or per-product-family subscription mechanism found on Epson's own site
Customer-specific notification: Broadcast — notices are addressed generically ('Dear Valued Customer') and published publicly, not limited to affected customers
Distributor involvement: Distributors mirror the same notices (e.g. Epson EOL PDFs appear in the Mouser PCN library), but the primary/authoritative source is Epson's own epsondevice.com domain

Flex Power ModulesPCN archive · verified Jun 25, 2026＋

Flex Power Modules (the DC/DC converter / power module business of Flex Ltd., official sites flexpowermodules.com and flex.com/products/power-modules) maintains a public, login-free archive of Product Discontinuation Notices (PDNs) with notices dated from 2019 through 2025. Per their own FAQ, when Flex has a PCN or PDN to issue it pushes the information through its Channel Partners, who relay it to affected customers active in roughly the previous three years — so proactive notification is partner/distributor-mediated and customer-specific rather than a self-service per-part-number subscription.

How notifications work

Lifecycle status is shown per part in the product selector: 'Active', 'NRND' (Not Recommended for New Designs, may not yet have a PDN), and 'Legacy' (a PDN has been issued and the part is in its Last Time Buy / End-of-Life period).
When Flex Power Modules has a PCN or PDN to issue, it is shared with its Channel Partners, who relay it to affected customers that have been active typically within the previous ~3 years (FAQ verbatim).
The most recent Product Discontinuation Notices are also posted publicly online in the Downloads & Resources area and on the dedicated product-discontinuation-notices page; individual PDNs are PDFs naming affected part series and dated in the filename (notices span 2019-2025).
No account or login is required to read the PDN archive or any individual notice.
For general product news (including new product notifications) customers can sign up for the Flex email newsletter (flex.com/subscribe) or follow the Power Modules LinkedIn page, but the FAQ does not document a PCN/PDN-specific email alert.
Lifecycle, alternative-part, and last-time-buy questions are handled by Flex's partners/representatives or by contacting Flex directly via the Power Modules contact-us form.

What your team should do

1.Bookmark and periodically check the public PDN archive at flex.com/products/power-modules/product-discontinuation-notices (and the Downloads & Resources page) for newly posted discontinuation notices - no login needed.
2.Because dates are in the notice filenames but there is no search UI, scrape or manually diff the archive list on a schedule (e.g. monthly) to detect newly added PDNs against your BOM part series (BMR/PKB/PKM/PKR/PIM/PMx prefixes).
3.Identify and stay 'active' with your authorized Flex Channel Partner / distributor of record, since proactive PCN/PDN notifications flow through partners to customers active within ~3 years - lapsed buyers may not be contacted directly.
4.Register your part numbers and contact details with that partner/rep so your account is on the affected-customer distribution list for PCN/PDN.
5.Monitor the per-part lifecycle status in the Flex product selector (Active / NRND / Legacy) for early warning before a formal PDN, and treat NRND as a design-out trigger.
6.Sign up for the general Flex newsletter and follow the Power Modules LinkedIn page for product news, but do not rely on them as a substitute for partner notifications or archive monitoring; contact Flex directly via the Power Modules contact-us form for last-time-buy dates and cross-reference alternatives.

Access summary

Public archive: Yes - public, login-free PDN archive at flex.com/products/power-modules/product-discontinuation-notices, also reachable via the Downloads & Resources page; individual PDNs are PDFs on the same domain
Searchable historical notices: Partially - notices are browsable as a dated list spanning 2019-2025 (dates embedded in each filename, e.g. PKM4000E 01-31-2019 through PKB4000 series 06-27-2025), but there is no search/filter/sort UI on the archive page itself
Account required: No - PDN archive and individual PDN documents are publicly viewable without any login or account
Email notification: Indirect - a general email newsletter (flex.com/subscribe) and a 'new product notifications' news section exist for product news, but the FAQ does not document an email alert specifically for PCN/PDN/EOL; proactive PCN/PDN notification is routed through Channel Partners to affected customers
Part-number subscription: Not clearly documented - no per-part-number or product-family PCN/PDN subscription is described on the official site; the only sign-up is the general product newsletter
Customer-specific notification: Customer-specific via partners - FAQ states PCN/PDN are shared with Channel Partners 'who will feed the information down to affected customers that have been active typically within the previous three years or so,' while the PDN archive itself is a public broadcast
Distributor involvement: Central - Flex sells through a 'global network of channel partners and representatives'; PCN/PDN notifications are explicitly distributed via Channel Partners, and RMAs/lifecycle questions are also routed through the originally-sourced channel/partner

InfineonNotification-policy page · verified Jun 25, 2026＋

Infineon's own quality page describes a push, customer-specific model: for major changes affecting a product's form, fit, function, quality or reliability, Infineon "informs the affected customers via a product/process change notification (PCN)," following JEDEC J-STD-046 with a minimum 90-day pre-ship notice. There is no clearly documented single public, searchable PCN/PDN archive covering the whole Infineon portfolio on infineon.com; the one searchable PCN system that is documented (legacy Cypress at cypress.com/pcn, searchable by part number or PCN number) requires login to download documents.

How notifications work

For major changes affecting form, fit, function, quality or reliability, Infineon states it 'informs the affected customers via a product/process change notification (PCN)' — a direct, customer-specific push, not primarily a public broadcast.
Infineon follows the international standard JEDEC J-STD-046; customers are notified a minimum of 90 days before the proposed first ship date of the changed product, and lack of acknowledgement within 30 days constitutes acceptance per the standard.
For legacy Cypress-portfolio parts, a PCN system at cypress.com/pcn lets users search by marketing part number or by PCN number, but downloading the document requires logging in with a user ID; access can be requested and is processed within ~48 hours (per Infineon Developer Community knowledge-base articles).
A myInfineon account provides profile-based 'Interests'/subscription settings for product updates and marketing communications, but a dedicated part-number-level PCN/PDN email alert is not clearly documented as a distinct feature.
Authorized distributors (e.g., Avnet/EBV) maintain their own PCN search and forwarding to their customers, so notices for parts bought through distribution may reach you via the distributor rather than directly from Infineon.

What your team should do

1.Ensure Infineon (and your franchised distributor) has current, monitored contact/quality emails on file for your buying entity, since Infineon's documented model pushes PCNs to affected customers with a purchasing relationship — notices may not reach you if contacts are stale.
2.Create a myInfineon account and review the profile 'Interests'/subscription settings to opt into available product update communications; confirm with Infineon support whether any PCN/PDN-specific alerting can be enabled, as this is not clearly documented.
3.For any legacy Cypress-portfolio parts, use the cypress.com/pcn search (by part number or PCN number) and request login access (processed in ~48 hours) so your team can retrieve and download the actual PCN documents.
4.Set up PCN monitoring through your authorized distributor(s) (e.g., Avnet/EBV PCN search), since distributors forward notices for parts purchased through them and may be your effective channel for distribution-bought components.
5.Confirm directly with your Infineon account/quality contact how PDNs (discontinuance / last-time-buy) are delivered and what lead times apply, as last-time-buy windows were not confirmed in public materials.
6.Cross-reference part numbers against the OPN translation table when searching, since legacy Cypress (CY) and Infineon designators differ and affect PCN lookup.

Access summary

Public archive: Policy/process page only
Searchable historical notices: Limited (legacy Cypress PCN search only; portfolio-wide archive not clearly documented)
Account required: Account required to download (login needed for legacy Cypress PCN system; viewing-without-account for full portfolio not clearly documented)
Email notification: Not clearly documented (myInfineon profile offers interest/newsletter subscriptions; a dedicated PCN/PDN email subscription is not clearly documented)
Part-number subscription: Not clearly documented
Customer-specific notification: Primarily customer-specific (Infineon states it informs the affected customers via PCN)
Distributor involvement: Distributor dependent (authorized distributors maintain their own PCN search/forwarding, e.g. Avnet/EBV; explicit forwarding obligation on Infineon's own domain not clearly documented)

IntelPCN archive · verified Jun 25, 2026＋

Intel (intel.com) publishes Product Change Notifications (PCN), Product Discontinuance Notifications (PDN), Product Support Notifications (PSN) and End of Service/Servicing Updates (ESUN/ESU) through a searchable "Product Change Notifications" collection in its Resource & Documentation Center (RDC). The collection is publicly browsable and searchable (by MM#, Intel Product Code, PCN/PDN number, processor number, and product filters), and individual notices can be web-viewed and downloaded as PDFs without an account. To receive email alerts you must create a free My Intel / RDC account and configure "Bookmark notifications," which Intel uses as the email mechanism within RDC.

How notifications work

Intel posts PCN, PDN (discontinuance/EOL), PSN, and ESUN documents to the 'Product Change Notifications' collection in the Resource & Documentation Center (RDC) on intel.com; each notice has a web view and a downloadable PDF.
The archive is publicly browsable and searchable without logging in - filter by Content Type (PCN/PDN/PSN), Product, Product Application, or Last Updated, and search by Intel Material Master number (MM#), Intel Product Code, PCN/PDN document number, or processor number.
A public banner notes some results are restricted; signing in (Standard access, immediate) or registering reveals additional content, and Premier access to confidential content requires a Corporate Non-Disclosure Agreement (CNDA).
Email alerts require a free My Intel / RDC profile; Intel's documented email mechanism is 'Bookmark notifications' - bookmark the PCN page, an individual notice, or a whole collection, then set frequency under My Intel Inbox Settings (PCNs appear under My Library: Revised Bookmarks).
An Intel support article also references a weekly Customer Notifications email subscription covering PCN/PDN and FPGA Customer Advisories, opted into via My Intel dashboard settings.
Intel's customer notification procedure follows JEDEC J-STD-046 (process/product change) and J-STD-048 (product discontinuance); FPGA/Altera lines have their own PCN/PDN/ADV quality pages.

What your team should do

1.Bookmark the Intel RDC 'Product Change Notifications' collection (intel.com Resource & Documentation Center, filter By Content Type) as the authoritative source for PCN/PDN/PSN/ESUN.
2.Create a free My Intel / RDC account, then enable Bookmark notifications and set the frequency under Inbox Settings so PCN/PDN changes are emailed to a monitored distribution list, not a personal inbox.
3.For each Intel part you use, look it up in the collection by MM#, Intel Product Code, or processor number, then bookmark the relevant product/collection (and individual notices) to scope alerts to your BOM.
4.If you need confidential or restricted notices, register for Standard access (immediate) and, where required, pursue Premier access via a Corporate Non-Disclosure Agreement (CNDA).
5.Periodically run a search/sort by Newest or Last Updated in the collection as a backstop to bookmark emails, and download the PDF copies for your change-control records.
6.Use Intel's RDC as the source of record rather than distributor-hosted copies (Digi-Key/Mouser), and for FPGA/Altera parts also check the dedicated FPGA PCN/PDN/ADV quality pages.

Access summary

Public archive: Yes - the RDC 'Product Change Notifications' collection houses PCN/PDN/PSN/ESUN and can be browsed and searched anonymously (public content); some content is restricted and requires sign-in/CNDA
Searchable historical notices: Yes - the collection holds a large historical set (job aid shows '5000 Results') searchable/filterable by content type, product, product application, MM#, Intel Product Code, and PCN/PDN/processor number, sortable by Newest/Last Updated
Account required: No account to view/search/download public notices; a free My Intel/RDC account is required to set up email (bookmark) notifications, and Standard/Premier access (Premier needs CNDA) is required to see restricted content
Email notification: Yes - email alerts are delivered via RDC 'Bookmark notifications' configured under My Intel Inbox Settings; a support article also references a weekly Customer Notifications subscription for PCN/PDN/FPGA advisories
Part-number subscription: Partial - subscription is by bookmarking the PCN page, individual notices, or whole collections rather than by entering an arbitrary part number; users locate the relevant product/collection then bookmark it for notifications
Customer-specific notification: Broadcast - notices are published to the public RDC archive for all users (Intel's notification process follows JEDEC J-STD-046 / J-STD-048); direct customer/distributor notification also occurs but the archive itself is general broadcast
Distributor involvement: Not required for access - Intel publishes notices directly on its own domain; distributors (e.g., Digi-Key/Mouser) also rehost Intel PCN/PDN PDFs, but the authoritative source is Intel's RDC

ISSIQuality-process page · verified Jun 25, 2026＋

ISSI (Integrated Silicon Solution Inc., official domain issi.com) is a memory maker (SRAM, DRAM, Flash) whose Quality and Reliability page states that for product and process changes, "notifications are sent out to customers via ISSI's PCN process." This is a quality-process statement describing a customer-directed PCN/EOL process; ISSI does not appear to publish a public, searchable PCN/PDN archive or a self-serve email/part-number subscription on its own domain. Individual ISSI PCN and EOL documents (labeled "Confidential") are findable in practice only via third-party distributors (Mouser, Digi-Key), not on issi.com.

How notifications work

ISSI's Quality and Reliability page (issi.com) states that for product and process changes, notifications are sent out to customers via ISSI's PCN process — a customer-directed notification process tied to its quality program.
ISSI positions itself around long-term support for industrial/medical customers, explicitly framing its value as reducing the number of PCNs and EOL notices customers receive (Long Term Support and Industrial/Medical pages on issi.com).
No public, searchable PCN/PDN/EOL archive was found on issi.com; individual ISSI PCN and EOL notices (e.g., for IS42S/IS45S SDRAM, IS43TR DDR3) are labeled 'Confidential' and in practice are found on third-party distributor sites (Mouser, Digi-Key).
ISSI runs an authenticated 'WorkFlow' portal (portal-workflow.issi.com / workflow.issi.com) requiring sign-in; it appears to be a customer/document workflow portal, but its exact role in delivering PCNs is not documented publicly.
ISSI maintains an authorized distributor network (e.g., Digi-Key, Mouser), which is the practical public channel for obtaining ISSI change/EOL documents.

What your team should do

1.Establish a direct line for PCNs: because ISSI states notices go 'to customers via ISSI's PCN process,' contact your ISSI sales/FAE or local rep and request that your purchasing/quality contacts be added to PCN/EOL distribution for the ISSI part numbers you use.
2.Work your distributor: since ISSI PCN/EOL PDFs surface primarily through authorized distributors (Digi-Key, Mouser), ask your distributor account team to enroll your affected MPNs in their PCN-alert programs as a backstop.
3.Maintain your own ISSI MPN watchlist and periodically check distributor PCN feeds (Mouser/Digi-Key) for ISSI notices, since there is no confirmed self-serve archive or subscription on issi.com.
4.If you have an ISSI WorkFlow portal account (portal-workflow.issi.com), confirm with ISSI whether PCNs/qualification documents are delivered there and ensure the right team members have access.
5.For long-life designs, leverage ISSI's long-term-support positioning: ask ISSI in writing for longevity/EOL commitments and advance PCN lead times on the specific parts you depend on.
6.Consider a third-party PCN aggregator (e.g., Accuris/SiliconExpert) to capture ISSI change notices automatically, given the absence of a public issi.com subscription.

Access summary

Public archive: No public searchable PCN/PDN archive found on issi.com; the quality page describes a customer-directed PCN process, not an archive. Individual PCNs surface only on third-party distributor sites.
Searchable historical notices: Not clearly documented
Account required: No account needed to read the quality-process page. ISSI operates an authenticated WorkFlow portal (portal-workflow.issi.com / workflow.issi.com) that requires sign-in; its role in PCN distribution is not clearly documented.
Email notification: Not clearly documented
Part-number subscription: Not clearly documented
Customer-specific notification: ISSI states notifications are 'sent out to customers via ISSI's PCN process,' implying a direct push to customers/affected accounts rather than a public broadcast; whether all customers or only affected ones receive each notice is not clearly documented. PCN PDFs are marked 'Confidential.'
Distributor involvement: Strong in practice: ISSI PCN/EOL documents are publicly available primarily through authorized distributors (Mouser, Digi-Key) rather than issi.com. ISSI maintains an authorized distributor network.

PCN documents carry a PCN number, issue date, type of change, and the affected Kingston part. Kingston also markets "advanced product change notification ... to ensure ample time for qualification and testing at the customer site."

Kingston publishes Product Change Notifications directly on its own domain: a per-part lookup at kingston.com/en/memory/search/pcn?partId=<MPN> and the source PCN documents as public PDFs under media.kingston.com/pcn/ (e.g., PCN_KSM26ED8_16HD_N.pdf).
Each PCN document includes a PCN number/revision, issue date, type of change (e.g., 'NEW PRODUCT'), and the affected Kingston part number with its capacity/spec.
A self-service 'Product Change Notification (PCN) Preferences' page (kingston.com/en/support/pcn/subscribe) lets you opt in to email notifications on Kingston part-number changes, selectable by product category.
Kingston markets its PCN program as 'advanced product change notification' intended to give customers ample lead time for re-qualification and testing.
The model is broadcast/self-service: PCN documents are public and anyone can subscribe, rather than notices being sent only to a closed list of affected accounts.

What your team should do

1.Subscribe at kingston.com/en/support/pcn/subscribe and select the product categories that cover your Kingston memory/SSD parts so PCN emails reach your procurement/quality inbox.
2.For each Kingston MPN in your BOM, bookmark/monitor its PCN page at kingston.com/en/memory/search/pcn?partId=<MPN> to check for new or revised notices.
3.Archive the source PCN PDFs from media.kingston.com/pcn/ into your own change-management system, since they carry the authoritative PCN number, dates, and change type.
4.Confirm with Kingston (or your Kingston account/FAE) whether you can also register specific part numbers for direct notification, since the public page describes category-level subscription.
5.Cross-check critical parts directly with Kingston sales/support rather than relying solely on your distributor, as distributor relay of Kingston PCNs is not officially documented.

KioxiaQuality-process page · verified Jun 25, 2026＋

Kioxia (a NAND flash / SSD memory maker, official domain kioxia.com) documents a formal Product Change Notification process in its own Quality Guidelines: a "Change Control Web System" feeds a "PCN (QA-IT) Customer Announcement System or Approval System" that routes change notices through the Sales Department directly to each customer, with customer approval required in advance for changes affecting product structure, function, characteristics or reliability. PCNs and product discontinuance/EOL notices (e.g., the 2026 2D NAND EOL with last-time-buy by 30 Sep 2026 and final shipments through 31 Dec 2028) are delivered directly to contracted/affected customers via Sales, not published in a public, searchable PCN archive on Kioxia's own domain; the only public searchable notice archive on the site covers consumer/personal products (software, security, end-of-support).

How notifications work

Kioxia's published Quality Guidelines define a formal Change Control Procedure (Figure 2-2-1): a Change Control Web System feeds a 'PCN (QA-IT) Customer Announcement System or Approval System' that issues change notices through the Sales Department to the customer.
For changes that modify product structure, functionality or characteristics, or significantly affect reliability, 'customer approval is obtained in advance' (a PCN-approval flow), making notices customer-specific rather than a public broadcast.
Product discontinuance / EOL is handled as direct customer notification: the 2026 traditional 2D NAND EOL set last-time-buy orders by 30 Sep 2026 and final shipments through 31 Dec 2028 (reported via press/distributors; the formal PDN reaches contracted customers directly).
Kioxia maintains a public, searchable notice archive only for personal/consumer products (apac.kioxia.com important-notices, 2017-2026; eol-products list) covering software, security and end-of-support items - not industrial part PCN/PDN.
Distribution is multi-channel: authorized distributors and sales representatives relay Kioxia changes, and distributors frequently publish their own PCNs/PDNs that cascade Kioxia NAND lifecycle changes to their customers.

What your team should do

1.Establish and maintain a direct Kioxia account relationship through your assigned Sales Office, distributor or representative (find via the official Sales Contacts directory at customer-us.kioxia.com/sales/lookup) so you are on the customer list that receives PCNs/PDNs.
2.Request enrollment in Kioxia's PCN/Change Control customer announcement and approval process during contracting, and confirm in writing which company contacts should receive change and discontinuance notices.
3.Ask your Kioxia sales/quality contact for the Quality Guidelines and the formal PCN/PDN/EOL process, including advance-notice period, last-time-buy windows and approval requirements, and capture these in your supply agreement.
4.Because Kioxia routes notices through distributors, ensure your distributor/CM is contractually obligated to forward Kioxia PCNs/PDNs and their own downstream change notices for affected part numbers.
5.Track lifecycle for your specific Kioxia MPNs via your sales/distributor channel (no public part-number subscription was found); for the active 2D NAND EOL, plan last-time-buys before 30 Sep 2026.
6.Use the public consumer important-notices archive only for personal-product software/security/end-of-support items - do not rely on kioxia.com for an industrial PCN archive; the authoritative channel is direct customer notification.

Access summary

Public archive: No public PCN/PDN archive for business/OEM parts on kioxia.com; the only public searchable notice archive (apac.kioxia.com important-notices / eol-products) is for personal/consumer products and covers software, security and end-of-support items, not industrial PCN/PDN
Searchable historical notices: Consumer notices are searchable by year/category (2017-2026); no searchable historical archive of industrial PCN/PDN notices found on the official domain
Account required: No account to view consumer notices (public); industrial PCN/PDN are delivered directly to customers via the Sales Department / Change Control Web System rather than a self-serve viewable page
Email notification: No documented self-serve PCN email-subscription. Kioxia sends product-update/transactional/warranty emails to registered users and marketing newsletters (with opt-out); industrial change notices reach customers through the direct customer/sales relationship
Part-number subscription: Not clearly documented
Customer-specific notification: Customer-specific: per the Quality Guidelines, PCNs are issued through Sales to affected customers and require customer approval/acknowledgment in advance for significant changes (not a broadcast public notice)
Distributor involvement: Yes: Kioxia sells through authorized distributors/representatives (sales lookup directory), and distributors (e.g., Apacer, ATP, TDK, Viking) issue their own downstream PCNs cascading Kioxia NAND changes; third-party distributor sites also host Kioxia PDN PDFs

Lattice SemiconductorPCN archive · verified Jun 25, 2026＋

Lattice publishes PCNs/discontinuance notices on its own "Product Change Notifications (PCNs)" web page (latticesemi.com/en/Support/PCN), where the notices are hosted as publicly downloadable PDFs (no login needed to open a notice; documents live under /-/media/LatticeSemi/Documents/ProductChangeNotification/). To be actively notified, customers register a Lattice web account and opt into PCN e-mail alerts; existing-account holders edit their subscription options. Notices are addressed broadly ("Dear Lattice Customers") and follow J-STD-46, under which a change is deemed accepted if no acknowledgement is received within 30 days.

How notifications work

Notices are posted on the Lattice 'Product Change Notifications (PCNs)' web page (latticesemi.com/en/Support/PCN); individual PCN/discontinuance PDFs are hosted directly on latticesemi.com and open without a login (e.g. /-/media/LatticeSemi/Documents/ProductChangeNotification/...).
To receive active alerts, customers register a Lattice web account and select the PCN (and/or newsletter) subscription option; a confirmation email activates the subscription. Existing-account holders enable alerts by editing their account subscription options.
Each PCN is addressed broadly ('Dear Lattice Customers') and governed by J-STD-46/JESD46: the change is 'deemed accepted by the customer if no acknowledgement is received within 30 days from this Notice.'
Notices state a conversion/sample timeline (e.g. 90-day conversion, 30-day sample-request cutoff) and an expiration date, and identify affected Ordering Part Numbers (often in an attached Excel spreadsheet).
PCN-related questions route to a Lattice contact (notices cite sales@latticesemi.com; the PCN inbox pcn@latticesemi.com also appears in search-surfaced material).
Discontinued/mature parts are additionally tracked on a separate 'Mature & Discontinued Devices' support page (latticesemi.com/Support/MatureAndDiscontinuedDevices).

What your team should do

1.Create or use a Lattice web account at latticesemi.com (Accounts/AccountRegister) and enable the PCN e-mail alert subscription so changes are pushed to your team; existing accounts should edit subscription options to turn PCN alerts on.
2.Use a shared/distribution mailbox when registering so alerts don't depend on one employee's account.
3.Bookmark and periodically review the public PCN web page (latticesemi.com/en/Support/PCN) and the Mature & Discontinued Devices page; download notices directly (no login needed to read them).
4.On receiving a PCN, check the affected Ordering Part Numbers (often in the attached Excel list) against your BOM, and acknowledge in writing before the stated deadline — silence past ~30 days is treated as acceptance under J-STD-46.
5.Track the conversion/sample-request cutoff and PCN expiration dates in each notice; request samples before the cutoff if you need to re-qualify.
6.For questions or to confirm coverage, contact Lattice via the addresses on the notice (sales@latticesemi.com; pcn@latticesemi.com) and ask your authorized distributor whether they also relay Lattice PCNs.

MacronixPCN archive · verified Jun 25, 2026＋

Macronix (a memory maker: NOR Flash, NAND Flash, Mask ROM) publishes a dedicated, public PCN-and-EOL archive on its official site at macronix.com/en-us/support/PCN-and-EOL, organized by product family (NOR Flash, NAND Flash, ROM), with individual PCN and EOL notice PDFs openly downloadable without login. Its Quality System page states it issues Product Change Notifications per JEDEC/ZVEI standards, and its Product Longevity Program documents a 10-year availability commitment for selected parts with a 1-year EOL notification period plus an additional year for final shipment. Macronix does not appear to offer a public email-subscription or part-number alert service for these notices.

How notifications work

Macronix maintains an official PCN and EOL archive on macronix.com under Support > PCN and EOL, split into NOR Flash, NAND Flash, and ROM product families.
Individual PCN (Product Change Notification) and EOL (End of Life / discontinuance) notices are published as openly downloadable PDFs that require no account or login to view.
Per its Quality System page, Macronix issues PCNs in reference to JEDEC and ZVEI standards for changes affecting form, fit, function, or product quality/reliability.
Under the Product Longevity Program (selected Serial NOR, Parallel NOR, and NAND Flash, including most automotive-grade parts), Macronix commits to up to 10 years of availability with a 1-year EOL notification period followed by an additional year for final shipment.
The same archive content is mirrored on the legacy/regional domain mxic.com.tw.

What your team should do

1.Bookmark and periodically poll the official archive at macronix.com/en-us/support/PCN-and-EOL (NOR Flash, NAND Flash, and ROM tabs) for new PCN/EOL notices, since no public email-subscription service was found.
2.Cross-check whether your Macronix MPNs are listed in the Product Longevity Program (MPLP) part list to know which parts carry the 10-year availability and 1-year EOL-notice + 1-year final-shipment terms.
3.Because the on-site archive lacks full-text search and loads dynamically, supplement monitoring with periodic web searches for 'Macronix PCN <part>' / 'Macronix EOL <part>' to catch indexed notice PDFs.
4.Ask your Macronix sales representative or distributor account team to confirm whether they can place you on a direct PCN/EOL distribution list and to relay notices for your specific part numbers (this is not documented on the public site).
5.Capture/archive relevant PCN/EOL PDFs locally when found, since the public archive may not be permanently searchable and notice URLs can change.

Access summary

Public archive: Yes - official PCN-and-EOL archive at macronix.com/en-us/support/PCN-and-EOL, organized by product family (NOR Flash, NAND Flash, ROM)
Searchable historical notices: Partially - historical PCN and EOL PDFs are browsable by product family and individually downloadable (and indexed by web search engines), but there is no on-site full-text search/filter; archive lists load dynamically via JavaScript
Account required: No - PCN/EOL notice PDFs are publicly accessible without any login or account
Email notification: Not clearly documented - no public email-alert/subscription mechanism found on macronix.com for PCN/EOL
Part-number subscription: Not clearly documented - no part-number or product-family subscription/alert feed found on the official site

MarvellCustomer portal · verified Jun 25, 2026＋

Marvell (marvell.com) distributes Product Change Notices through its authenticated Customer Portal (Salesforce/Okta-based, marvell.my.site.com / mymarvell.force.com), which has a dedicated "PCN" tab and a per-asset Notification system tied to "My Products"/"My Projects." There is NO public searchable PCN archive: Marvell's Public Document Library is publicly searchable but offers no PCN/PDN/EOL document type, and portal access requires registration plus a valid NDA on file.

How notifications work

PCNs are published in Marvell's Customer Portal under a dedicated 'PCN' tab: 'The PCN tab shows Product Change Notices' (Portal User Guide v2.0).
Accessing the portal requires registration with a company email and a valid NDA on file: 'Marvell validates customer NDA and sends activation email'; 'A valid NDA must be on file with Marvell' (Customer Portal Onboarding Guide).
Notifications are configured per product/asset: 'Under My Products and My Projects, specific folders or assets can be selected for addition to Notification system and/or Favorite widget.'
Alerts surface via the in-portal bell icon / Notifications widget, and can be enabled per asset: 'Enable notifications for specific assets using the radio button'; Settings let users modify 'notifications for Collaterals Products and Projects.'
The public Document Library (marvell.com/support/doc-library.html) is searchable but its document-type filter contains no PCN/PDN/EOL category, so it is not a PCN archive.
Marvell PCNs follow an acknowledgement/approval workflow with affected customers (per Marvell-issued PCN text), rather than an open public broadcast.

What your team should do

1.Establish or confirm an NDA with Marvell (via your Marvell sales representative) — it is a prerequisite for any documentation and PCN access.
2.Register each relevant engineer/SCM contact at the Marvell Customer Portal (marvell.com/registration.html; login at marvell.my.site.com) using company email so they receive activation and change-notice alerts.
3.In the portal, add your in-use Marvell products/folders under 'My Products'/'My Projects' and enable per-asset notifications (radio button) so PCNs for those parts trigger alerts.
4.Monitor the portal 'PCN' tab and the Notifications widget/bell, and check Settings to confirm Collaterals/Products/Projects email notifications are enabled.
5.Because access is NDA- and folder-gated (not a public feed), route PCN acknowledgement/approval through your Marvell account team and respond before the stated implementation date — unacknowledged changes may be treated as accepted.
6.For exact part-number coverage and any distributor-relayed copies (Digi-Key/Mouser re-host some Marvell PCNs), verify against the authoritative portal copy rather than relying on third-party mirrors.

Access summary

Public archive: No public PCN archive — the public Document Library (marvell.com/support/doc-library.html) lists no PCN/PDN/EOL document type; PCNs live only in the login-gated Customer Portal
Searchable historical notices: Within the authenticated Customer Portal the PCN tab and asset search are available, but no public historical PCN search exists on the open site
Account required: Yes — registration is required to view, and a valid NDA must be on file ('Marvell validates customer NDA'; 'access to all Marvell documentation requires that you be under a current NDA')
Email notification: Yes — the portal Notification system plus bell/Notifications widget; registration/activation and alerts are email-driven, configurable in Settings
Part-number subscription: Yes at the product/asset level — 'specific folders or assets can be selected for addition to Notification system'; 'Enable notifications for specific assets using the radio button' (per product/folder, not documented as exact MPN strings)
Customer-specific notification: Access-gated to NDA customers and to the product folders they are granted (My Products = NDA-protected assets; My Projects = 'customer specific folders'); not a public broadcast
Distributor involvement: Not clearly documented

MCCPCN archive · verified Jun 25, 2026＋

MCC (Micro Commercial Components, official domain mccsemi.com) publishes a public "ECN/PCN List" archive (mccsemi.com/ECNPCN/List) plus individual PCN/EOL PDFs hosted on its own domain (/pdf/ecn/ and /pdf/eol/), with notices dating back to at least 2015. Notices are generic broadcasts ("Dear Customer"/"Dear Valued MCC Customers") issued by the "MCC PCN Team"; acknowledgement is requested within 30 days via the customer's local MCC sales representative, and changes are "considered approved" unless contested in writing within 30 days. The site is behind a Cloudflare challenge, so the live List page could not be rendered by automated fetch, but the archive URL and PCN format are confirmed via search results and an extracted official PCN PDF.

How notifications work

MCC posts Process/Product Change Notifications (PCN), Advance PCN (APCN), Final PCN (FPCN) and End-of-Life (EOL) notices as individual PDFs on its own domain (mccsemi.com/pdf/ecn/ and /pdf/eol/) and indexes them on a public 'ECN/PCN List' page (mccsemi.com/ECNPCN/List).
Notices are broadcast, not customer-specific: they open with 'Dear Customer' / 'Dear Valued Micro Commercial Components (MCC) Customers' and are signed by the 'MCC PCN Team'.
Each notice is structured with Notification Date, Implementation Date, Last Time Buy Date, Last Time Ship Date, Change Type, PCN number, a description/impact section, and tables of affected part numbers.
Recipients are asked to acknowledge receipt within 30 days via their local MCC sales representative; the disclaimer states that unless an MCC sales rep is contacted in writing within 30 days, all described changes are considered approved.
MCC states it maintains its change-notification process in line with JEDEC J-STD-046/J-STD-048 (referenced on its Quality page).
The same PCN/EOL PDFs are also mirrored by distributors such as Mouser and Digi-Key, but the authoritative copies live on mccsemi.com.

What your team should do

1.Bookmark and periodically check the official ECN/PCN List archive at https://www.mccsemi.com/ECNPCN/List for new PCN/APCN/FPCN/EOL notices affecting your MCC part numbers (note: the site uses a Cloudflare challenge, so use a normal browser).
2.Because MCC pushes notices through sales channels rather than a public email-alert form, establish a named MCC sales representative or franchised distributor (Mouser/Digi-Key) contact and ask to be added to their PCN distribution for your active MCC MPNs.
3.Treat the 30-day acknowledgement window seriously: silence is interpreted as approval, so review each notice's Last Time Buy / Last Time Ship dates and respond in writing to your MCC sales rep if a change is unacceptable.
4.Cross-check your BOM against the affected-part tables in each EOL/PCN; for EOL parts, plan last-time-buys and qualify any MCC-offered replacement parts before the implementation date.
5.Use mccsemi.com/Contact/Index for clarification and request qualification reports for Final PCNs (MCC notes these are available on request).
6.Periodically poll a third-party lifecycle service (e.g. SiliconExpert) as a backstop, since MCC offers no automated per-part email/subscription alert on its own domain.

Access summary

Public archive: Yes - public 'ECN/PCN List' at mccsemi.com/ECNPCN/List plus PCN/EOL PDFs under mccsemi.com/pdf/ecn/ and /pdf/eol/
Searchable historical notices: Yes - archive lists historical notices (PCN PDFs found dating back to at least 2015); whether the list page offers a search/filter box is Not clearly documented
Account required: No account required to view notices - PCN/EOL PDFs and the ECN/PCN List are publicly reachable on the open domain (no login wall observed)
Email notification: Not clearly documented - no email-subscription/sign-up form was found on the official domain; MCC instead pushes notices to customers via local sales representatives
Part-number subscription: Not clearly documented - no per-part-number or product-family subscription/alert mechanism found on the official domain
Customer-specific notification: Broadcast - PCNs use a generic 'Dear Customer'/'Dear Valued MCC Customers' salutation from the 'MCC PCN Team', not addressed to individual affected customers
Distributor involvement: Distributors mirror MCC PCNs (e.g. Mouser, Digi-Key host the same PDFs), and MCC routes acknowledgement through 'your local sales representative'; the canonical archive is on MCC's own domain

MicrochipPCN archive · verified Jun 25, 2026＋

Microchip runs a combined PCN/EOL (Product/Process Change Notification and End-of-Life) service centered on its PCN web page, where anyone can view and search all notifications without an account or login, and registered myMicrochip users can additionally receive email notifications. PCN and EOL notices are broadcast (posted publicly and emailed to registered subscribers per their preferences), with only custom automotive/PPAP products routed directly to the customer's email on file.

How notifications work

Microchip operates a single PCN/EOL service covering Manufacturing Change, Document Change (data sheet/errata/silicon die revision), and End-of-Life (product discontinuance) notifications; per the official PCN/EOL Notification Policy, all are posted on the PCN web page and emailed to registered users.
The policy states two viewing options: Option 1 - clients receive notices by email after completing the electronic registration form; Option 2 - clients may 'view all PCN/EOL notifications without registration or login' by selecting 'view all notifications' on the PCN web page.
The public PCN list is searchable by PCN Number, Date, PCN Type, and Description (Description matches package type, lead count, CCB number, part number/CPN, manufacturing site, and BOM), plus a PCN Type drop-down (EOL, Silicon Die Revision, Manufacturing Change, Document Change, Development Tool).
Email subscribers register via a myMicrochip account at www.microchip.com/pcn, must select 'Subscribe to Product Change Notifications,' and choose cadence (Daily, Weekly, or Not Interested).
Subscription scope is either Option 1 (all PCNs for current and future devices) or Option 2 (only selected products), where products can be specified three ways: Catalog Part Number (CPN), Device Family, or Copy/Paste from File; selections appear under a 'My Products' tab.
Per the EOL Policy, an EOL notice is 'broadcast' when there has been business activity within the preceding three years (longer for automotive/military/space); it is published on the PCN web page and emailed to registered users, and includes LTB (Last Time Buy) and LTS (Last Time Ship) dates.
For clients who purchase custom automotive or PPAP products, custom PCNs are routed directly to the email address on file and include a request for written LTB approval.

What your team should do

1.Create a myMicrochip account and register at www.microchip.com/pcn, then select 'Subscribe to Product Change Notifications' (required for the email service) and pick a cadence (Daily or Weekly) so notices reach the right inbox.
2.Choose Option 2 (selected products) and load your active part numbers via Catalog Part Number (CPN), Device Family, or the Copy/Paste-from-File method; verify your list under the 'My Products' tab and watch for invalid-part-number errors on paste.
3.Use the public PCN web page (no login needed) to baseline and audit historical notices for your parts - search by PCN Number, Date, PCN Type drop-down, or Description (which matches CPN/part number, package, lead count, BOM, site, CCB).
4.If you buy custom automotive or PPAP products, confirm Microchip has the correct email address on file, since those custom PCNs are routed directly and may require written Last Time Buy approval.
5.On any EOL/PDN, review the notice for LTB/LTS dates and the Parts Affected list (which may name drop-in or functionally equivalent replacements), and contact your local Microchip sales office promptly for replacement or timing questions.
6.Periodically re-check the public PCN archive as a safety net in case an email is missed, and use the PCN FAQ at the bottom of the PCN page or your local Microchip sales office for service questions.

Micron distributes PCNs and EOL/discontinuance notices through an automated push system that emails the notice to every customer who received an affected part within the prior 24 months, and to local distributors for disbursement to distribution-only buyers. Micron's own CSN-12 Customer Service Note documents this customer-specific/distributor model; it describes no public, self-serve PCN archive or part-number email-subscription portal.

How notifications work

Per Micron's official CSN-12 Customer Service Note (PCN/EOL Systems), once a Change Review Board approves a change for notification, 'the PCN/EOL system automatically sends the information... to all customers that have received the affected product within the previous 24-month period' — a push to customers with a recent purchasing relationship, not a public broadcast.
'Notifications are also sent to local distributors for disbursement to those customers who have made purchases solely through distribution' — so distributor-channel buyers are reached via their distributor (this is the documented path for accessing Micron PCNs without a direct account).
EOL/discontinuance follows the same system as PCNs; timelines reference JEDEC standards (J-STD-046 for PCN; J-STD-048 for EOL, with a minimum 6-month last-order and 12-month last-ship window for both non-SSD and SSD).
Each notice contains type/description/reason for change, the complete list of affected Micron part numbers, implementation date, method of identification (old vs. new device), and marketing + engineering contacts.
Customers are expected to acknowledge receipt within 30 days and give final approval within 90 days; no response is treated as acceptance, and Micron sales/FAE may follow up directly.
A Micron.com account advertises access to 'secure documents... subscriptions, and more,' and the obsolete-parts catalog at micron.com/products/obsolete sits behind login — but Micron's public materials do not document a self-serve PCN email-subscription or a publicly searchable PCN/PDN archive. (The only confirmed micron.com email-alert signup is Investor Relations, which is unrelated to PCNs.)

What your team should do

1.Ensure Micron has correct, monitored PCN/quality-contact email addresses on file for your buying entity, since notices are pushed automatically only to customers who purchased an affected part in the last 24 months — lapsed or contact-less accounts can miss notices.
2.If you buy through a distributor (Avnet, Arrow, Future, etc.), confirm with that distributor that they forward Micron PCN/EOL notices to you, because Micron sends distribution-only customers' notices to the distributor for disbursement.
3.Engage your Micron sales representative or FAE to request PCN/EOL notification setup, ask whether any account-based subscription or notice feed is available for your account, and request copies of notices affecting your specific part numbers — the public site does not expose a self-serve part-number subscription.
4.Build the 30-day acknowledgment / 90-day approval windows into your internal PCN workflow, since Micron treats non-response as acceptance of the change.
5.For discontinued parts, use the (login-gated) obsolete-parts catalog at micron.com/products/obsolete and ask your rep for the relevant EOL notice and last-time-buy dates; plan to the JEDEC minimums (6-month last order, 12-month last ship).
6.Consider a third-party PCN aggregation service (or your distributor's PCN feed) as a supplementary source, since Micron does not publish a public, searchable PCN/PDN archive of its own.

Monolithic Power SystemsNotification-policy page · verified Jun 25, 2026＋

MPS (Monolithic Power Systems, official domain monolithicpower.com) publishes a formal Product Obsolescence Policy (PDN) on its own domain stating that when a Product Discontinuation Notice is issued it directly notifies its sales force, distributors, and customers who purchased the affected product within the past 24 months (84 months for Automotive parts) — a customer-specific push model, not a public broadcast. MPS does not document any public, searchable PCN/PDN archive or a self-serve email/part-number subscription on its own domain; change/discontinuance notices reach you through your direct/distributor account relationship.

How notifications work

Per the official Product Obsolescence Policy (PDN), when a discontinuation notice is approved and issued, MPS notifies its sales force, any distributors, and customers who purchased the affected product within the past 24 months (84 months for Automotive parts).
Notification is customer-specific (push to affected accounts and channel partners), not a public broadcast archive that anyone can browse.
Last-Time-Buy / Last-Time-Ship: the April 2023 policy allows up to 6 months from the PDN date to place final orders (LTB) and a subsequent 6 months for delivery, terminating 12 months from the PDN date.
MPS states discontinuations are rare and guarantees products are not discontinued unless there have been no new orders for at least 24 months (84 months Automotive), a supplier is lost, or a replacement product is offered.
MPS publishes its obsolescence/PDN policy as a downloadable document on its own domain, but does not document a public searchable PCN archive or a self-serve part-number subscription.

What your team should do

1.Ensure MPS (and your authorized MPS distributor) holds current, monitored contact emails for your account — PDNs are pushed only to purchasers of record, distributors, and the sales force, so stale contacts mean missed notices.
2.Buy through and stay in regular contact with your authorized MPS distributor, since distributors are explicitly named PDN recipients and are the practical relay for change/discontinuance notices.
3.Keep purchase activity / order history current on the parts you depend on — eligibility to be notified is tied to having purchased within the past 24 months (84 months for Automotive).
4.On a PDN, act within the documented window: place Last-Time-Buy orders within 6 months of the PDN date and schedule delivery within 12 months of the PDN date.
5.For parts you do not buy directly or buy infrequently, proactively contact MPS's quality department or your sales rep to request change/discontinuance status, since there is no self-serve public PCN archive to monitor.
6.Download and retain the official MPS Product Obsolescence Policy (PDN) from media.monolithicpower.com as your reference for timelines and notification scope.

Access summary

Public archive: No public searchable PCN/PDN archive documented on the MPS domain; only a downloadable Product Obsolescence Policy document is published
Searchable historical notices: Not clearly documented
Account required: Policy document is public (no login); a myMPS+ account exists for site features but is not documented as a PCN-notification channel
Email notification: Not clearly documented as a self-serve PCN email subscription; MPS pushes PDNs directly to affected customers/distributors via the account relationship (a general marketing newsletter exists but is not a change-notice channel)
Part-number subscription: Not clearly documented
Customer-specific notification: Customer-specific: MPS notifies sales force, distributors, and customers who purchased the product within the past 24 months (84 months for Automotive parts)
Distributor involvement: Yes — distributors are explicitly named recipients of PDNs alongside direct customers and the MPS sales force

NexperiaNotification-policy page · verified Jun 25, 2026＋

Nexperia (official domain nexperia.com, regional mirrors such as nexperia.cn) issues formal Change Notifications in four classes — PCN (product change), CIN/CN-...I (customer information), DN (discontinuation/PDN), and RN — and centralizes both viewing and subscription inside the authenticated "My Nexperia" portal. The official quality and customer-support pages state "Find all Change Notifications (PCN, CIN, DN, RN) for sales items in My Nexperia" and let users set "Change Notification (CN) preferences" that control both the in-portal CN view and the CN emails. There is no login-free public archive on nexperia.com — the PCN list and preferences pages redirect to login.nexperia.com (OpenID Connect), so unauthenticated browsing of the full historical archive is not available on Nexperia's own domain; the individual notice PDFs are instead widely mirrored by authorized distributors (Mouser, TTI, Digi-Key, Farnell).

How notifications work

Nexperia issues four Change Notification types for sales items — PCN (product change, '...F'), CIN/Customer Information ('...I'), DN/Discontinuation ('...DN', the PDN/EOL notice), and RN — all surfaced in the authenticated 'My Nexperia' portal (nexperia.com/quality and the customer-support PCN page state 'Find all Change Notifications (PCN, CIN, DN, RN) for sales items in My Nexperia').
Viewing the full archive and managing subscriptions both require a My Nexperia account: the PCN list (/my/pcn/details) and preferences (/my/pcn/my-preferences) redirect to the login.nexperia.com OpenID Connect login. By default a logged-in user 'will see all Change Notifications that are available to you.'
Email alerts (CN emails) are sent from pcn@nexperia.com to people who are 'a designated contact or subscribed to Nexperia Quality Notifications'; the same My Nexperia CN preferences control both the in-portal view and which emails you receive.
Discontinuation notices follow JEDEC EIA/JESD48 and classify parts as Full Withdrawal, Version Withdrawal, or Non-Manufacturable, with last-order/last-time-buy windows (commonly ~6 months multi-source, ~9 months sole-source/customer-specific, up to a 12-month delivery period from the issue date; no LTB for Non-Manufacturable parts).
PCN acknowledgement is expected to conform to JEDEC J-STD-046, and lack of acknowledgement of the PCN constitutes acceptance of the change; content questions go to the local Nexperia Sales Support Team (or pcn@nexperia.com).
EOL/excess inventory is supported through the Rochester Electronics partnership; the actual notice PDFs are also broadly mirrored by authorized distributors (Mouser, TTI, Digi-Key, Farnell).

What your team should do

1.Create/maintain a My Nexperia account at nexperia.com and ensure your procurement/quality owners are named as 'designated contacts' so they are auto-enrolled in CN emails for your purchased parts.
2.In My Nexperia, set Change Notification (CN) preferences (/my/pcn/my-preferences) to receive all relevant CN types (PCN, CIN, DN, RN) by email and review the in-portal CN view, since this is the authoritative on-domain source.
3.Confirm CN emails from pcn@nexperia.com are allow-listed (do not reply to them; they are auto-distributed) and route them to a monitored shared inbox/ticket queue.
4.Treat the My Nexperia portal as the source of truth and use distributor-hosted PDFs (Mouser/TTI/Digi-Key/Farnell) only as a public cross-check, since Nexperia provides no login-free archive on its own domain.
5.On any DN/discontinuation, immediately note the issue date, withdrawal type (Full/Version/Non-Manufacturable), and last-order/last-time-buy date, and plan last-time buys within the stated window (~6 mo multi-source, ~9 mo sole-source); route EOL/excess buys to Rochester Electronics (rocelec.com).
6.Acknowledge PCNs to your Nexperia Sales Support Team within the JEDEC J-STD-046 window, since silence is treated as acceptance; escalate substantive questions to your local Nexperia sales contact or pcn@nexperia.com.

Access summary

Public archive: No login-free public PCN archive on nexperia.com; the full archive (PCN/CIN/DN/RN) lives behind the My Nexperia login (PCN list/preferences pages redirect to login.nexperia.com). Individual notice PDFs are publicly mirrored by distributors (Mouser/TTI/Digi-Key/Farnell), not on Nexperia's own domain.
Searchable historical notices: Historical notices are accessible/viewable within My Nexperia for logged-in users ('By default you will see all Change Notifications that are available to you'); specific search/filter capabilities are Not clearly documented on the public page.
Account required: Yes for viewing the on-domain archive and for managing email subscriptions — both /my/pcn/details and /my/pcn/my-preferences redirect to the login.nexperia.com OpenID login wall. Viewing individual notice PDFs via distributors needs no Nexperia account.
Email notification: Yes. CN emails are sent (from pcn@nexperia.com) to recipients who are 'a designated contact or subscribed to Nexperia Quality Notifications'; cadence/content controlled by CN preferences in My Nexperia (/my/pcn/my-preferences).
Part-number subscription: Not clearly documented as explicit per-part-number or per-product-family opt-in; the documented model is CN preferences that filter which Change Notifications 'available to you' appear, defaulting to all available to the account. Granularity beyond that is Not clearly documented.
Customer-specific notification: Hybrid: emails are pushed to designated contacts / quality-notification subscribers, and the portal shows the CNs 'available to you' (i.e., scoped to the account's products). Acknowledgement is expected per JEDEC J-STD-046, and lack of acknowledgement constitutes acceptance of the change.
Distributor involvement: Yes. Notice PDFs are broadly distributed/mirrored by authorized distributors (Mouser, TTI, Digi-Key, Farnell). EOL/excess and last-time-buy fulfillment is handled via the Rochester Electronics partnership; channel partners are an additional notification path beyond direct designated contacts.

Niko SemiconductorPCN archive · verified Jun 25, 2026＋

Niko Semiconductor Co., Ltd. (NIKO-SEM, niko-sem.com), a Taiwan-based power MOSFET and power-management/analog IC maker, publishes a free, public, searchable EOL (End-of-Life / discontinuance) archive on its own site under the "EOL" menu, with a structured table (Letter No., Issued Date, Device, Alternative, Last Purchase Date, Last Delivery Date, Remark) spanning 2012 to present and direct PDF downloads of each formal "NIKO-SEM EOL Notification" letter. The archive covers discontinuance (PDN/EOL) only; no separate process/material PCN archive, email-subscription, or part-number alert service was found on the official domain.

How notifications work

NIKO-SEM maintains a dedicated, public 'EOL' page (under Products/Applications > EOL) that lists every End-of-Life / discontinuance notice as a table: Letter No., Issued Date, Device, Alternative part, Last Purchase Date, Last Delivery Date, and Remark.
Each row links to a downloadable PDF 'NIKO-SEM EOL Notification' letter stating the phase-out, last-purchase date, and last-delivery date, written in JEDEC-style discontinuance language; downloads require no account (verified).
The archive is historical and searchable: ~161 pages of records back to December 2012, with a device search box, a column filter dropdown, and a CSV Export option.
The notices NIKO-SEM publishes are EOL/discontinuance (PDN-equivalent); no separate process/material Product Change Notification (PCN) archive was found on the official domain.
No email subscription, RSS feed, or part-number/product-family alert service was found on niko-sem.com; the EOL archive is pull-based (check or search the page) rather than push.
'Product News' is a separate, marketing-oriented new-product feed and is not a change/discontinuance notice channel.

What your team should do

1.Bookmark and periodically poll the NIKO-SEM EOL archive (niko-sem.com > EOL, portal_d747.php) since there is no email/RSS push - schedule a recurring manual or scripted check.
2.Use the EOL page's device search box to look up your specific NIKO-SEM part numbers (e.g. Px-series MOSFETs) and record any matching Letter No., Last Purchase Date, and Last Delivery Date.
3.Export the EOL table to CSV (Export All Columns) and diff it against your prior snapshot to detect newly added discontinuances and capture last-buy windows.
4.Download and archive the per-part EOL Notification PDF for any affected device as your formal discontinuance record, and note the listed 'Alternative' part where provided.
5.Because notices are broadcast (not pushed to specific customers), contact NIKO-SEM's local Agent / Business Service Office (listed under Contact Us) to confirm last-time-buy quantities and ask to be alerted directly for your active part numbers.
6.Track Last Purchase Date deadlines in your obsolescence/BOM-risk system and plan last-time-buy or qualify the listed alternative before the cutoff.

Access summary

Public archive: Yes - a public EOL/discontinuance archive at niko-sem.com (EOL menu, portal_d747.php) listing all EOL notices with downloadable PDF letters; no login needed (verified by direct fetch)
Searchable historical notices: Yes - 161 pages of historical EOL records from 2012-12-01 onward, with per-column device search, a filter dropdown, and CSV Export (Export All / Displayed Columns)
Account required: No - both viewing the EOL table and downloading the EOL Letter PDFs work without any login or account (confirmed: EOL letter PDF downloaded HTTP 200, no auth); a generic 'member login' template block exists site-wide but does not gate EOL access
Email notification: Not clearly documented - no email-subscription, RSS, or 'notify me' mechanism for EOL/PCN found on the official site
Part-number subscription: Not clearly documented - no per-part-number or product-family alert subscription found; the EOL page supports on-demand search by device, not push subscriptions
Customer-specific notification: Broadcast - EOL notices are published in a public archive open to anyone, not gated to only affected customers; individual customer outreach (e.g. via agents/sales) is not documented on the site
Distributor involvement: Likely - NIKO-SEM lists an Agent / Business Service Office (distributor/sales) network under Contact, but the EOL archive itself is published directly by the manufacturer; distributor role in EOL delivery is Not clearly documented

NuvotonPCN archive · verified Jun 25, 2026＋

Nuvoton (Taiwanese MCU/semiconductor vendor; official domain nuvoton.com) publishes a public, no-login End-of-Life (EOL) product listing page that functions as an obsolescence archive — tables of discontinued parts with notification dates, last-order/last-shipment dates, and recommended replacements, plus a downloadable EOL-list PDF. There is, however, no dedicated public PCN (process/spec change) archive on Nuvoton's own domain, and no documented email or part-number subscription for change/EOL alerts; the EOL page itself is the primary public-facing artifact, and individual obsolescence-notice PDFs surface mainly through distributors (e.g., DigiKey).

How notifications work

Nuvoton maintains a public End-of-Life (EOL) page (nuvoton.com/product-related-information/eol/) listing discontinued parts with notification dates, last-order dates, last-shipment dates, and recommended replacement parts; no login is required.
A downloadable EOL-list PDF (nuvoton.com/export/sites/nuvoton/files/EOL-list.pdf) is also published as a consolidated list.
Nuvoton's Product Longevity Program (PLP) commits to a minimum 10 years of form/fit/function availability from a product's introduction date, with continued support beyond that based on demand (pricing/MOQ/NCNR may apply).
No dedicated public PCN archive (for process/spec changes, as distinct from EOL) was found on Nuvoton's own domain; the Quality Documents page lists certifications only, and the News page has no PCN/EOL category.
No PCN/EOL email-subscription or part-number alert service is documented on the official site; myNuvoton accounts offer document-update tracking and an e-paper news subscription, not change-notice alerts.
Individual Nuvoton EOL/obsolescence notice documents are commonly distributed and hosted via authorized distributors (e.g., DigiKey), so distributor and rep channels are a practical notification path.

What your team should do

1.Monitor Nuvoton's public EOL page (nuvoton.com/product-related-information/eol/) and the downloadable EOL-list PDF on a schedule, diffing against your BOM part numbers, since there is no email/part-number subscription to push these to you.
2.Capture the per-part notification, last-order, and last-shipment dates from the EOL listing to plan last-time-buy windows.
3.Rely on the Product Longevity Program (min. 10 years form/fit/function from introduction) for lifecycle planning, and check recommended-replacement parts listed in the EOL tables.
4.Set up change/EOL alerts through your authorized Nuvoton distributors and franchised reps (e.g., DigiKey), which host individual obsolescence notices and can flag affected line items.
5.Contact Nuvoton's customer support / sales (nuvoton.com/contact-us) directly to ask for proactive PCN/EOL notification on your specific part numbers, since no self-service subscription is documented.
6.Periodically check Nuvoton's News page (filter by year/category) for any product-status announcements, though it currently carries no dedicated PCN/EOL feed.

Access summary

Public archive: Yes - public no-login EOL product listing at nuvoton.com/product-related-information/eol/ with discontinued parts, notification/last-order/last-shipment dates and recommended replacements; a downloadable EOL-list PDF is also published. No separate public PCN (process/spec-change) archive found on the domain.
Searchable historical notices: Partial - the EOL page presents current EOL listings in tables but shows no historical/date-filtered archive or search of past notices; the News page is filterable by year/category but carries no PCN/EOL category.
Account required: No - EOL listings, Product Longevity Program, and Quality Documents are publicly viewable without login. A myNuvoton account exists but is not required to view EOL/obsolescence info.
Email notification: Not clearly documented - no PCN/EOL email subscription is documented on Nuvoton's site. myNuvoton offers document-update tracking and an e-paper news subscription, but neither is described as a PCN/EOL alert.
Part-number subscription: Not clearly documented - no part-number or product-family change-notification subscription is offered on the official site.
Customer-specific notification: Not clearly documented - Nuvoton does not state on its own pages whether EOL/change notices go only to affected customers or are broadcast; the public EOL page serves as a broadcast-style listing.
Distributor involvement: Partial - Nuvoton's own pages do not document a distributor notification flow, but individual Nuvoton EOL/obsolescence notice PDFs are hosted by distributors such as DigiKey, and the site links to Worldwide Rep & Disti for purchasing.

NXPNotification-policy page · verified Jun 25, 2026＋

NXP issues Product Change Notices (PCNs) and Product Discontinuance/Discontinuation Notices (PDNs/DNs) about 90 days before implementation under JEDEC J-STD-046, and delivers them primarily as targeted emails to designated customer contacts and to users who have subscribed through a "My NXP" account, rather than as a public broadcast. Individual notice documents are reachable on nxp.com by direct URL and discontinued parts have a searchable end-of-life lookup, but the change-management page itself is a policy/process page, not a general searchable PCN archive.

How notifications work

NXP communicates any change that may affect fit, form, function, quality or reliability via Product Change Notices (PCNs) approximately 90 days before implementation; each notice includes summary, effective date, impacted part numbers, and contact info (per the Change Management and Customer Communication quality page).
Per JEDEC Standard J-STD-046, lack of acknowledgment of a PCN within 30 days is treated as acceptance of the change.
Notices are delivered as emails through NXP's electronic PCN (ePCN) system; recipients receive them because they are a 'designated contact or subscribed to NXP Quality Notifications' - i.e., targeted to affected/registered customers rather than broadcast publicly.
In the ePCN tool, the 'Products' tab shows the subscriber's affected part numbers and lets the logged-in user obtain the attached notice documents, making notifications effectively part-number / product-family scoped.
Discontinuances (PDN/DN) follow defined last-time-buy windows (e.g., ~6 months for multi-source, ~9 months for sole-source/customer-specific products, with delivery up to ~12 months) and are also published as individual DN pages under the Discontinued and Replacement Parts (END-OF-LIFE) section.
Authorized distributors (Digi-Key, Mouser, Farnell) receive NXP notices and forward/host the PCN/PDN PDFs for their own customers.

What your team should do

1.Create or use a 'My NXP' account, then go to Account Settings and use 'Request or Update Product Change Notification' to request PCN/Quality Notification subscription for your parts (this generates a service request NXP's team acts on).
2.Ensure the right people are listed as your organization's designated NXP contacts so ePCN emails reach a monitored inbox, not an individual who may leave.
3.Use the ePCN tool's 'Products' tab after login to review and confirm the affected part numbers tied to your account, and download attached notice documents.
4.For end-of-life tracking, use NXP's Discontinued and Replacement Parts (END-OF-LIFE) page to search by part number and review last-time-buy terms and suggested replacements.
5.If you only have a notice number, retrieve the document directly via nxp.com/pcn/<number> or the product-change-notice doc URLs; for ePCN access or content questions, contact NXP's Global Quality Support Team / your local NXP Sales Support.
6.Also monitor your authorized distributors' (e.g., Digi-Key, Mouser) PCN feeds as a secondary channel, since they forward NXP notices - but treat NXP's own ePCN/email subscription as the system of record.

Access summary

Public archive: Policy/process page only; individual notices reachable by direct URL but no general public searchable PCN list confirmed
Searchable historical notices: Limited - discontinued-parts END-OF-LIFE page allows part-number search; no confirmed public archive of all historical PCNs
Account required: No account to view individual notice URLs; My NXP account required to subscribe and to use the ePCN tool
Email notification: Email notification available to designated contacts and via My NXP subscription request
Part-number subscription: Part/product-family scoped via ePCN - the ePCN 'Products' tab lists the subscriber's affected part numbers
Customer-specific notification: Primarily customer-specific - emailed to designated contacts / Quality Notification subscribers, not a public broadcast
Distributor involvement: Distributors also forward notices - Digi-Key, Mouser and Farnell host/forward NXP PCN/PDN PDFs

onsemiPCN archive · verified Jun 25, 2026＋

onsemi runs a public PCN portal (pcnPub.do / pcn.do) that publishes Product Change Notifications and Product Discontinuance Notifications for standard products, with individual documents served openly at onsemi.com/pcn/public/final-document/...; no login is needed to view these public notices. Separately, customers can register a company email with PCN.Support@onsemi.com to receive PCN/PDN emails and log in to a Customized Portal that shows company-specific addendums listing only their affected parts, so onsemi both broadcasts publicly and notifies affected customers directly.

How notifications work

onsemi publishes PCNs and PDNs on a public portal (pcnPub.do / pcn.do) covering standard products; the portal states it provides access to all public Product Change Notifications subject to its Terms of Use.
Public notices can be searched by part number (e.g. pcnPub.do?pn=<MPN> or pcn.do?action=search&PartNumber=<MPN>) and individual documents are served openly at onsemi.com/pcn/public/final-document/... without a login.
Notice types include Initial Product/Process Change Notification (IPCN, issued at least ~120 days before the change), Final Product/Process Change Notification (FPCN, normally ~90 days before), and Product Discontinuance Notification (PDN).
Customers can register for email notifications by sending first name, last name and company name from a company-specific email address (no Gmail/Hotmail) to PCN.Support@onsemi.com.
Registered customers can log in to a Customized Portal and receive customer-specific PCN/PDN addendums that list only the parts affecting their company; these accompany the public/generic notice.
Per onsemi's terms, a change is considered accepted unless the customer inquires in writing within 30 days of notice delivery; for discontinuances, ~6 months is typically allowed from the notice date to place final lifetime-buy orders.

What your team should do

1.Bookmark and periodically search the public PCN portal at https://www.onsemi.com/PowerSolutions/pcnPub.do (part-number search via the pn / PartNumber parameter) to check your active MPNs for PCNs and PDNs.
2.Register for onsemi PCN/PDN email notifications by emailing your first name, last name and company name from a company email address (not a personal/free provider) to PCN.Support@onsemi.com.
3.After registering, log in to the onsemi Customized PCN Portal to view company-specific addendums listing the notices that affect only your purchased parts.
4.Act within the documented windows: respond in writing within 30 days if you object to a change, and place last-time/lifetime-buy orders within the ~6-month window stated on a PDN.
5.For each affected MPN, retrieve the full final-document PDF from the public portal and confirm the document number/revision and effective date against your BOM.
6.Also confirm with your onsemi authorized distributor whether they relay onsemi PCN/PDN notices for your account, since distributor forwarding is not documented by onsemi and should not be relied on as your only channel.

Access summary

Public archive: Public searchable archive (pcnPub.do / pcn.do portal of published PCN/PDN documents)
Searchable historical notices: Searchable historical notices (part-number search; published IPCN/FPCN/PDN docs with document numbers and revisions)
Account required: No account to view public published notices; account/registration required for customized company-specific notices
Email notification: Email subscription available (register company email with PCN.Support@onsemi.com)
Part-number subscription: Part-number search supported on the public portal; customized email registration is company/account-based rather than self-service per-part subscription
Customer-specific notification: Both: notices published publicly and registered customers also receive company-specific addendums of their affected parts

RenesasPCN archive · verified Jun 25, 2026＋

Renesas posts PCNs/PDNs publicly through the PCN/PDN Search Tool at renesas.com/en/support/pcn-search, which lets anyone search by part number or keyword across PCN, PDN/discontinuance, end-of-life, price-increase and product-advisory/alert notices, with individual notices viewable as public PDFs. In parallel, Renesas notifies customers with a purchasing relationship directly (PCN documents cite a 30-day acknowledgement and 90-day objection window) and explicitly places responsibility on buyers/distributors to cascade notices to downstream third parties; affected-product lists are also posted on the site for about three months.

How notifications work

Public access: the PCN/PDN Search Tool (renesas.com/en/support/pcn-search) lets anyone search product notices by part number or keyword; categories include Product Change Notices, Product Discontinuance Notices, End of Life, Price Increase, Product Advisory and Product Alert. A 'See all product notices' link opens the broader document search.
Individual notices are public PDFs that can be opened and read without logging in (e.g., document pages under renesas.com/en/document/pcn/...).
Email alerts run through the Document Update Notification system tied to a My Renesas account: when you open a document download link, a pop-up offers to notify you if it is updated. You can subscribe to 'just this document' or to 'all documents related to this Page' (including future additions), and choose Daily, Weekly or Monthly cadence. Renesas states it cannot guarantee delivery and advises periodically checking the site.
Subscriptions are managed in the My Renesas user profile ('Edit Subscriptions' / 'Edit Profile'); creating/logging into an account is required to subscribe or manage notifications.
Direct customer notification: PCN documents reference a customer acknowledgement window (30 days, after which the change is deemed approved) and a 90-day objection window after timely acknowledgement, indicating notices are sent directly to customers with a purchasing relationship.
Affected products are also listed publicly on the website for approximately three months following a change, and PCNs make it the responsibility of the buyer/distributor (or anyone who resells/transfers the product) to notify downstream third parties of the change.

What your team should do

1.Use the public PCN/PDN Search Tool at https://www.renesas.com/en/support/pcn-search to search your Renesas part numbers (and keywords) for existing PCNs, PDNs, EOL, and discontinuance notices; this needs no login.
2.Create a My Renesas account and use the Document Update Notification system to subscribe to the specific Renesas part/document pages you use, choosing the page-level option so future notices on that page also reach you; set the Daily/Weekly/Monthly cadence that fits your review cycle.
3.Because Renesas says it cannot guarantee email delivery, schedule a periodic manual re-check of the PCN/PDN Search Tool for your critical part numbers rather than relying on email alone.
4.Confirm with your Renesas sales contact or franchised distributor that your organization is on the direct PCN distribution list for the parts you buy, since customer-specific notices carry the 30-day acknowledgement / 90-day objection windows you may need to act within.
5.Ask your distributor(s) to forward Renesas PCNs/PDNs to you in writing, since Renesas places responsibility on buyers/distributors to notify downstream parties.
6.When a PCN is found, note the acknowledgement deadline (typically 30 days) and objection window (typically 90 days) and route it to engineering/quality for impact assessment before the windows lapse.

Access summary

Searchable historical notices: Searchable historical notices (search by part number/keyword)
Account required: No account to view notices; account required to subscribe

RichtekQuality-process page · verified Jun 25, 2026＋

Richtek (richtek.com; a Taiwanese power-management IC vendor, now an MTK/MediaTek subsidiary) documents a formal Product Change Notification process on its official Quality & Reliability site, run per J-STD-046 and ZVEI-DeQuMa. PCNs are issued directly and customer-specifically to customers who purchased within the past two years (90 days advance notice standard, 180 days for automotive); there is no public, searchable PCN/PDN archive on richtek.com and no documented PCN/EOL email-subscription channel — the MyRichtek "Datasheet Alert" and newsletter features cover datasheet/marketing updates, not change notices.

How notifications work

Richtek runs a formal Product Change Notification (PCN) process aligned to J-STD-046 and ZVEI-DeQuMa, covering change initiation, evaluation, verification, customer notification, and implementation.
Per the official page, PCNs are issued to customers who have made purchases within the past two years - i.e., customer-specific direct notification rather than a public broadcast.
Advance notice is at least 90 days before shipment of the changed product for standard products, and at least 180 days for automotive products.
Changes are categorized (e.g., customer approval required, information-only, or no-notify), determining the notification path.
MyRichtek (free account) offers a 'Datasheet Alert' that emails users when a subscribed product's datasheet is updated, plus product newsletters - but neither is documented as a PCN/PDN/EOL alert channel.
No public searchable PCN/PDN archive, end-of-life/last-time-buy notice repository, or EOL-specific subscription is documented on richtek.com.

What your team should do

1.Ensure your company is an on-record direct customer of Richtek (purchasing within the trailing ~2 years) so you fall inside their customer-specific PCN distribution.
2.Confirm the correct PCN recipient contact(s) on your account with your Richtek sales/FAE or quality contact, since notification is direct-to-customer rather than via a public feed.
3.Create a free MyRichtek account and add your Richtek part numbers to 'Datasheet Alert' to catch datasheet revisions by email (note: this is datasheet updates, not a substitute for PCN/PDN).
4.Because there is no public PCN archive on richtek.com, request the specific PCN/PDN documents directly from your Richtek contact when a change is announced, and ask explicitly about last-time-buy / last-time-ship dates for any EOL.
5.If you buy through a distributor (e.g., Digi-Key/Mouser), also enroll in that distributor's lifecycle/PCN feed as a secondary catch, since some Richtek PCN PDFs surface there.
6.For automotive parts, leverage the 180-day notice window to plan qualification/last-time-buy, and route notices into your BOM/obsolescence tracking.

Access summary

Public archive: No public PCN/PDN archive found on richtek.com (the change-management page is a process description, not an archive; the only public PCN PDFs are hosted by third-party distributors)
Searchable historical notices: No searchable historical PCN/PDN database documented on the official domain
Account required: A free MyRichtek account/login is required for the related Datasheet Alert and newsletter features; PCN issuance itself is a direct customer notification (no account documented as required to receive a PCN)
Email notification: PCNs are sent directly to eligible customers; a separate MyRichtek 'Datasheet Alert' emails users when a datasheet is updated, but it is not documented as covering PCN/PDN/EOL
Part-number subscription: The Datasheet Alert lets a logged-in user add specific products to be notified on datasheet updates, but no part-number/family subscription specifically for PCNs/PDNs is documented
Customer-specific notification: Customer-specific: PCNs go to customers who made purchases within the past ~2 years, not a public broadcast
Distributor involvement: Not clearly documented (the official change-management page does not mention distributors in the notification flow)

ROHMNotification-policy page · verified Jun 25, 2026＋

ROHM (official domain rohm.com) notifies customers of changes through a combination of its product-lifecycle "supply status" framework, per-product PCN status banners on rohm.com product pages, and a formal customer-directed PCN process (customers must acknowledge a Product/Process Change Notification within 30 days, with non-acknowledgment treated as acceptance). ROHM does not appear to host a public, searchable archive of PCN/PDN PDF documents on its own domain — full-text PCN/PDN archives are maintained by distributors (TTI, Mouser, Digi-Key), not on rohm.com.

How notifications work

ROHM issues formal Product/Process Change Notifications (PCN) and Product Discontinuance Notifications (PDN/EOL) to customers; customers must acknowledge receipt within 30 days, and lack of acknowledgment within 30 days is treated as acceptance of the change.
Each product's lifecycle is tracked via ROHM's supply status classifications (Under Development, Recommended, Active, Not Recommended for New Designs, Last Time Buy, Obsolete), defined on rohm.com/supply_status.
Individual product pages on rohm.com display a PCN status banner when a change is scheduled (e.g., 'A Product Change Notice (PCN) is scheduled for this product...'), directing customers to their sales representative or the Contact Us form.
A MyROHM account (rohm.com/login) lets customers tag favorite products or product categories and receive email update alerts; this is the closest self-service email-alert mechanism ROHM documents.
ROHM does not publish a public, searchable PCN/PDN document archive on rohm.com; the actual PCN/PDN PDFs are distributed to customers and mirrored by authorized distributors (TTI, Mouser, Digi-Key).

What your team should do

1.Create a MyROHM account at rohm.com/login and tag the specific ROHM part numbers and product categories you use to receive email update alerts.
2.Establish a direct relationship with your ROHM sales representative / FAE or authorized distributor so you are on the formal PCN/PDN distribution list and respond to PCN acknowledgments within the required 30 days.
3.Periodically check the supply status indicator on each part's rohm.com product page and watch for the 'PCN scheduled' banner to catch upcoming changes early.
4.Because rohm.com has no public PCN archive, use distributor PCN search tools (TTI/Mouser/Digi-Key) to pull and retain the actual PCN/PDN PDFs for your parts, but treat ROHM's direct notice as the authoritative source.
5.When a Last Time Buy / discontinuance is announced, act within ROHM's stated last-time-buy / last-time-ship windows in the PDN to place final orders.

Access summary

Public archive: No public searchable PCN/PDN document archive on rohm.com; the supply_status page is informational (lifecycle definitions) only. Full-text PCN/PDN PDFs are hosted by distributors, not ROHM's own domain
Searchable historical notices: Not on rohm.com; historical PCN/PDN documents are searchable via distributor archives (e.g., TTI keeps ~12 months plus older), not the manufacturer site
Account required: Viewing supply status and product-page PCN banners needs no account; the MyROHM account (rohm.com/login) is required to tag products and receive email update alerts
Email notification: MyROHM account holders can 'Tag Favorite Products or Product Categories and receive email update alerts'; a separate marketing eNewsletter exists but is not a PCN/discontinuance feed
Part-number subscription: MyROHM allows tagging favorite products / product categories to receive email update alerts (product/family-level), but it is not explicitly documented as a dedicated PCN subscription
Customer-specific notification: Formal PCNs are issued to customers through ROHM sales/QA channels with a 30-day acknowledgment requirement, indicating direct notification of affected customers rather than a purely public broadcast
Distributor involvement: Significant: authorized distributors (TTI, Mouser, Digi-Key) host the searchable PCN/PDN document archives and PDFs that ROHM's own domain does not publish openly

SemtechNotification-policy page · verified Jun 25, 2026＋

Semtech's Corporate Quality Manual (Section 9.5, "Customer Notifications," hosted on semtech.com) documents that Semtech issues four notification types — Change Notifications (PCN), End-of-Life (EOL), Waivers, and Quality Alerts — and sends them by e-mail. PCNs/EOLs are customer-specific: they go only to customers who maintain a notification agreement with Semtech (and, for EOL, who purchased the affected part within the previous 24 months), not as a public broadcast. No public, searchable PCN/EOL archive or self-serve email-subscription page was found on semtech.com; historical PCN/EOL PDFs are only visible via third-party distributors.

How notifications work

Semtech provides four notification types per its Corporate Quality Manual Section 9.5: Change Notifications (PCN), End-of-Life Notifications (EOL), Waivers, and Quality Alerts.
PCNs: Semtech gives 90-day advance notice for major product/process changes affecting form, fit, function, or reliability, to customers who have entered into a notification agreement; a shorter window is stated in the letter if business conditions require.
Customers get an accept/reject window on a PCN; if a customer does not respond within the specified period, Semtech assumes the change is accepted. Automotive-grade product uses its own PCN form/number and requires customer approval before shipping.
EOLs: Semtech makes reasonable attempts to give 180-day advance notice of discontinuance, issued to all customers who purchased the affected product within the previous 24 months and who maintain a notification agreement; the notice includes a last-time-buy date and may reference replacement parts.
Delivery is by e-mail ('the notification is sent to the customer using e-mail') — it is a direct, customer-specific dispatch tied to the notification agreement, not a public broadcast or self-serve subscription.
No public, searchable PCN/EOL archive or self-subscribe email page was found on semtech.com; the on-site mySemtech / Document Portal requires registration and access approval.

What your team should do

1.Establish a notification agreement with Semtech (via your Semtech sales contact / FAE or the support page at semtech.com/company/contact/support) so your buying entity is enrolled to receive PCN and EOL emails directly — this is the documented path to coverage.
2.Provide and keep current the distribution email(s) that should receive PCN/EOL/Quality Alert notices, since delivery is by email to customers under agreement.
3.Register for the mySemtech Document Portal (semtech.my.site.com/DP) and request access; use it for product documents and any available change/quality materials, as there is no public PCN archive.
4.Because EOL coverage is tied to purchases in the previous 24 months, route Semtech purchases through identifiable accounts (direct or via a distributor that maps to your account) so you remain in scope for EOL notices.
5.Track Semtech PCN/EOL numbers (and watch distributor PCN feeds like Mouser/Digi-Key) as a secondary check, since historical notices are not searchable on semtech.com; reconcile any distributor-sourced notice against your BOM.
6.Note the response windows: respond to PCNs within the stated period (silence is treated as acceptance) and place last-time-buy orders before the EOL last-time-buy date.

Access summary

Public archive: No — no public PCN/EOL archive found on semtech.com; historical notices surface only via third-party distributors (Mouser, Digi-Key)
Searchable historical notices: No — no searchable historical notice archive on the official domain
Account required: Notifications are delivered directly by email under a notification agreement; the on-site document portal (mySemtech / Document Portal) is login-gated and requires registration/approval to access private documents
Email notification: Yes — the Quality Manual states notifications are 'sent to the customer using e-mail,' but only to customers under a notification agreement (not a self-serve public subscription)
Part-number subscription: Not clearly documented — no part-number or product-family self-subscription mechanism described; coverage is governed by the notification agreement and, for EOL, by prior-24-month purchase history
Customer-specific notification: Customer-specific — PCNs go to customers 'who have entered into a notification agreement'; EOLs go to customers who purchased the affected product within the previous 24 months and maintain a notification agreement
Distributor involvement: Not clearly documented as an official channel; in practice Semtech PCN/EOL PDFs are widely hosted by distributors (Mouser, Digi-Key), but this is not described in Semtech's own notification policy

Silicon LabsPCN archive · verified Jun 25, 2026＋

Silicon Labs (silabs.com, Austin TX) publishes Product/Process Change Notices, Revision Change Notices, and End-of-Life/Discontinuance notices as individually titled, numbered PDFs in a public, unauthenticated directory at silabs.com/documents/public/pcns/. Notices follow the JEDEC J-STD-046 model (silence for 30 days = acceptance), include LTB/Last Order/Effective dates and replacement part mappings for EOLs, and direct customers to their sales rep or PCN@silabs.com; registered Silabs.com accounts can opt into PCN email notifications.

How notifications work

Each notice is a standalone numbered PDF (e.g. EOL Change Notice #2024-05-30-1543) published in the public directory at silabs.com/documents/public/pcns/; older notices use 7-digit numeric IDs (e.g. PCN-1402262), newer ones use date-based IDs (e.g. 2025-07-07-1656).
Notice types observed: Process Change Notice (PCN), Revision/Process Revision Change Notice (RCN/PRCN), Datasheet update PCNs, and End of Life (EOL) / Discontinuance notices.
EOL/discontinuance notices carry an EOL Issue Date, Last Order Date, and Effective Date, mark post-issue orders Non-Cancellable/Non-Returnable, support Last Time Buy (LTB), and include an Existing Part # to Replacement Part # mapping with drop-in-compatible indicators.
Customer response follows JEDEC J-STD-046: 'Lack of acknowledgment of the PCN within 30 days constitutes acceptance of the change.' Customers can approve early by emailing the PCN number to PCN@silabs.com.
For questions or further data, notices direct customers to their Silicon Labs sales representative (list at silabs.com).
Registered Silabs.com account holders can receive PCN notifications by email; 'PCN notifications' is a documented category in Silicon Labs email preferences alongside documentation updates and product releases.

What your team should do

1.Bookmark and periodically scrape the public PCN directory silabs.com/documents/public/pcns/ and cross-reference notice titles/part numbers against your BOM, since notices are individual PDFs rather than a filterable feed.
2.Create a free account at silabs.com/profile and opt into PCN email notifications via the Silabs.com email preferences so change/EOL notices reach a monitored distribution list.
3.Establish a relationship with your Silicon Labs sales representative (the documented channel for affected-part details and transition plans) and have them flag PCNs/EOLs for your specific part numbers.
4.Treat the 30-day window seriously: assign an owner to review each relevant PCN, since non-response is contractual acceptance under JEDEC J-STD-046; email PCN@silabs.com with the PCN number to formally acknowledge or approve early.
5.For EOL notices, act on the Last Order Date and Effective Date promptly, evaluate the listed replacement part and drop-in-compatible flag, and place LTB orders before the deadline (orders after issue are NCNR).
6.Use distributor mirrors (Mouser/Digi-Key) only as a backup discovery aid, then validate against the silabs.com copy as the authoritative source.

Access summary

Public archive: Yes - PCN/RCN/EOL notices are published as public PDFs under silabs.com/documents/public/pcns/, downloadable without login
Searchable historical notices: Partial - many years of historical notices (2014-era numeric IDs through 2025/2026 date-based IDs) are publicly hosted and indexed by search engines, but no clearly documented date/part filterable PCN search UI on the public site was confirmed
Account required: No to view/download public PCN PDFs; a free Silabs.com account is required to subscribe to PCN email notifications and access registered-only content
Email notification: Yes - 'PCN notifications' are an explicit category of Silicon Labs email communications, managed via Silabs.com email preferences / community subscription after registering
Part-number subscription: Not clearly documented - email preferences advertise PCN/documentation notifications generally; per-part or per-product-family PCN subscription granularity was not confirmed on official pages

STMicroelectronicsNotification-policy page · verified Jun 25, 2026＋

STMicroelectronics distributes PCNs (Product/Process Change Notifications) and PTNs/PDNs (Product Termination / discontinuance notices) through its standard change-management and end-of-life notification policies, delivered to customers via ST's sales channels and distributors rather than through a confirmed self-service public archive. The st.com page that documents this is a notification-POLICY page describing the process; ST's own published guidance for getting on the PCN list points customers to their local ST sales office, and the actual PCN/PTN PDF documents are most readily found publicly on distributor sites (Mouser, DigiKey, Farnell/Newark, Anglia).

How notifications work

ST states that in case of significant volume decrease, technology or manufacturing changes it will 'notify customers using the standard STMicroelectronics product/process change policy (PCN)', and that 'ST provides customers with a Product/Process Change Notice at the soonest,' respecting international standards (e.g. JEDEC) and specific customer requirements ST has accepted.
End-of-life is handled under the standard ST End-Of-Life notification policy (PTN). ST's Product Longevity program commits to availability of 7, 10, 15, or 20 years 'including the notification period' defined in that policy. Example ST PTN documents follow JEDEC JESD48-A, typically with a last-order-entry window and a last-delivery (final shipment) date roughly 6 and 12 months from the notice respectively (per individual PTN documents, not a stated universal policy number).
Notification is oriented to customers with a purchasing/design relationship: ST's public guidance for being added to the PCN list directs customers to their local ST sales office, and the Support FAQ tells users to open a Support case referencing a specific product number to confirm the applicable notification — indicating notices are routed through accounts/sales rather than a public broadcast feed.
Customer obligations are time-boxed: ST documentation indicates customers acknowledge receipt and submit any evaluation-sample requests within 30 days of the notification.
Distributors play a real forwarding role: the actual ST PCN/PTN PDF documents are publicly hosted and searchable on distributor portals (Mouser /PCN/, DigiKey, Farnell/Newark, Anglia registration/pcn_ptn), which is where third parties most reliably retrieve ST notices.
No self-service ST-hosted PCN email-subscription or part-number-subscription portal was found on st.com; the notification.html page is a policy/process description, not a searchable PCN archive.

What your team should do

1.Establish the relationship channel: have your buyers/ST account manager or authorized distributor confirm your company is on ST's PCN/PTN distribution list for the ST MPNs you use — ST's own guidance is to request this through your local ST sales office.
2.For any specific part, open an ST Support case (st.com/support) referencing the exact product number to confirm its lifecycle status and the applicable change/EOL notification, since ST routes notices by product and account.
3.Because notices are customer/sales-routed, mirror them via your distributors: enroll in PCN/PDN alerting from your authorized ST distributors (Mouser, DigiKey, Farnell/Newark, Anglia, etc.), which publicly host ST's PCN/PTN PDFs and offer their own subscription feeds.
4.Use ST's Product Longevity program data (7/10/15/20-year commitments) on st.com to risk-rank your ST parts proactively, rather than relying solely on receiving a PTN.
5.Track the 30-day response window: ST documentation indicates acknowledgment and any evaluation-sample requests are due within ~30 days of a PCN, and PTNs carry JEDEC-style last-order-entry / last-delivery deadlines (commonly ~6 and ~12 months in ST's PTN documents) — build internal SLAs to act before those dates.
6.Do not assume an st.com self-service email or part-number PCN subscription exists; if your process needs one, confirm current capability directly with ST Support or your sales contact before relying on it.

Texas InstrumentsNotification-policy page · verified Jun 25, 2026＋

Texas Instruments distributes PCNs/PDNs primarily by notifying affected customers of record directly (per JESD46) — TI's own PCN documents state the affected-device list reflects parts "customers have purchased within the past twenty-four months," and questions are routed to a local Field Sales Rep or the PCN team (PCN_ww_admin_team@list.ti.com). The ti.com page is a policy/process description, not a publicly searchable PCN/PDN archive; while a myTI account lets you set part-number "product, tool & software" alerts, the documented alert triggers (datasheet, errata, pricing & availability, etc.) do not explicitly include PCN/discontinuance notices.

How notifications work

TI states it complies with the industry standard JESD46 for product/process change notification (and J-STD-048 for obsolescence): 'Customers will be notified of major changes which affect the form, fit, function, or adversely affect quality or reliability of the product.'
TI's actual PCN documents indicate the listed affected devices are 'the devices that customers have purchased within the past twenty-four months,' showing notices are targeted to affected purchasing customers of record rather than broadcast.
For obsolescence, TI's quality FAQ states it allows 12 months for last order and an additional 6 months for final delivery; accelerated EOLs carry last-buy/final-delivery dates in the notice.
Customers acknowledge/respond to a PCN (the documents request acknowledgement, typically within 30 days) via their local TI Field Sales Representative or the PCN team at PCN_ww_admin_team@list.ti.com.
Separately, a myTI account allows part-number 'Product, tool & software alerts' delivered as one weekly digest email, but the documented triggers are data sheet, errata, application notes, white papers, user guides, models, pricing and availability, and software versions — PCN/lifecycle/discontinuance are not listed among them.
Authorized distributors (e.g., Mouser, Digi-Key, TTI, Avnet) host and forward TI PCN/PDN PDFs, which is often where individual notices are publicly accessible.

What your team should do

1.Treat TI's direct customer-of-record channel as the primary path: make sure TI has current contacts for your buying entity so PCN/PDN notices for parts you have purchased in the last 24 months reach you.
2.Establish a relationship with your local TI Field Sales Representative and keep the PCN team address (PCN_ww_admin_team@list.ti.com) on file for acknowledgements and to query specific PCN numbers.
3.Create a myTI account and add your TI part numbers to 'Product, tool & software alerts' for the weekly digest — useful for datasheet/availability changes, but do not rely on it as a PCN/discontinuance feed since those are not documented triggers.
4.Because TI does not document a public searchable PCN/PDN archive, capture and archive each notice you receive (PCN/PDN number, affected MPNs, dates) in your own system rather than expecting to re-find it on ti.com.
5.Use your authorized distributors (Mouser, Digi-Key, TTI, Avnet, etc.) as a secondary channel — they host and forward TI PCN/PDN documents and often run their own PCN search/subscription tools.
6.If you buy through distribution rather than direct, confirm your distributor will forward TI PCNs/PDNs to you, since TI's direct notice may go to the distributor of record.

Access summary

Public archive: Policy/process page only
Searchable historical notices: Not clearly documented
Account required: myTI account required to subscribe to alerts; no account for the public policy page
Email notification: Email alerts available for registered (myTI) users as a weekly digest
Part-number subscription: Part-number alerts exist via myTI, but PCN/discontinuance not in documented triggers
Customer-specific notification: Primarily sent to affected customers of record (parts purchased in prior 24 months)
Distributor involvement: Distributors also host/forward TI PCN/PDN documents

ToshibaPCN archive · verified Jun 25, 2026＋

Toshiba's semiconductor arm (Toshiba Electronic Devices & Storage Corporation) publishes a public, no-login NRND/EOL "Not Recommended for New Design and EOL Announced Product List" on its official domain (toshiba.semicon-storage.com), browsable per product family with a parametric "eol" search filter. However, formal Product Change Notification (PCN) and discontinuance (BBHKN-numbered) documents themselves are issued directly to affected customers and distributors rather than posted as a downloadable public archive on Toshiba's own domain — the actual PCN PDFs are found only on distributor sites (TTI, Mouser, Anglia), and Toshiba's official quality/contact pages route change/EOL inquiries to the local Toshiba sales representative.

How notifications work

Toshiba Electronic Devices & Storage Corporation maintains a public, no-login 'Not Recommended for New Design (NRND) and EOL Announced Product List' on toshiba.semicon-storage.com, browsable per product family and via a parametric 'eol' search filter.
Formal Product Change Notifications use a BBHKN-#### issue-number format and are issued to affected customers; the documents state they are notifying customers of changes (e.g., wafer/assembly site moves, marking changes) with implementation timelines.
Toshiba's own domain does not appear to host a downloadable public archive of the actual PCN/PDN notice PDFs; those documents are propagated to and re-hosted by authorized distributors (TTI, Mouser, Anglia).
The official Contact page routes sales, engineering, and product inquiries to the customer's local Toshiba Sales Representative; no dedicated self-serve PCN/EOL email-subscription channel was found on the reviewed official pages.
A free myToshibaSemicon web membership exists, but its documented benefits are tools (online circuit simulator, cross-reference search, saved parametric searches, webinars), not a documented PCN/EOL email subscription.

What your team should do

1.Monitor Toshiba's official NRND/EOL list at toshiba.semicon-storage.com (Semiconductor > product family > 'Not Recommended for New Design and EOL Announced') and the parametric '/parametric/eol' view for your part families on a recurring cadence, since there is no confirmed Toshiba-domain email push.
2.Establish a direct line to your local/assigned Toshiba Sales Representative and request to be placed on the distribution list for PCNs and discontinuance (PDN/EOL) notices for your specific MPNs - this is the channel Toshiba's contact page points to.
3.Because Toshiba routes PCN documents through distributors, subscribe to PCN feeds from your authorized distributors (e.g., TTI, Mouser) for Toshiba and cross-reference the BBHKN issue numbers against the parts you buy.
4.Create a free myToshibaSemicon account to use cross-reference search and saved parametric searches to identify replacements when a part appears on the NRND/EOL list (note: account does not provide a documented PCN email feed).
5.Capture BBHKN-numbered notices and last-time-buy / last-order dates as they arrive from your sales rep or distributor, since dated notice documents are not published per-part on Toshiba's own NRND/EOL index.

Access summary

Public archive: Yes for NRND/EOL: a public, no-login product list of NRND/EOL-announced families is on toshiba.semicon-storage.com; but no public downloadable archive of PCN/PDN notice documents on Toshiba's own domain
Searchable historical notices: Partial: the NRND/EOL list is browsable/parametric-searchable by product family, but it lists deprecated series without dated, downloadable historical PCN/PDN documents per part
Account required: No to view NRND/EOL list (public). A free myToshibaSemicon account exists but its documented benefits are circuit simulator, cross-reference, saved searches, webinars - not a documented PCN feed
Email notification: Not clearly documented for semiconductor PCN/EOL on the official domain; no PCN/EOL email-subscription mechanism found on toshiba.semicon-storage.com pages reviewed
Part-number subscription: Not clearly documented
Customer-specific notification: PCNs/discontinuance notices are issued directly to affected customers (BBHKN-numbered notices state they 'inform customers'); the NRND/EOL list itself is a broadcast public page
Distributor involvement: Yes - Toshiba PCN documents (BBHKN issue numbers) are distributed to and re-hosted by distributors such as TTI, Mouser, and Anglia; Toshiba contact page directs customers to local Toshiba sales reps

VicorPCN archive · verified Jun 25, 2026＋

Vicor (vicorpower.com) operates a Quality Center with a dedicated, publicly accessible Product Change Notices page that lists historical PCNs (covering changes, discontinuances, and End-of-Life notifications) with dates, change types, and affected model numbers, plus links to the individual PCN PDFs. The same page also offers a "Complete the form to receive Vicor Product Change Notices" sign-up to receive notices, and individual PCNs are addressed broadly ("To Our Customers" / "Important Notice to our Customers") rather than only to specific affected customers.

How notifications work

Vicor publishes Product Change Notices in its Quality Center at vicorpower.com/quality-center/product-change-notices - a public page listing PCNs with dates, change types, and affected model numbers, each linking to a PDF (under vicorpower.com/documents/pcn/).
The archive includes specification changes, discontinuances, and End-of-Life (EOL) notifications, with historical notices spanning multiple years.
No account or login is required to browse the list or download the individual PCN PDFs.
The PCN page offers an email sign-up - 'Complete the form to receive Vicor Product Change Notices' - so customers can be notified of new notices.
Individual notices are addressed broadly ('To Our Customers' / 'Important Notice to our Customers') and are publicly posted, i.e. broadcast rather than sent only to specifically affected customers.
EOL/discontinuance PCNs typically state affected part numbers and dates (e.g. last-time-buy / migration guidance) within the notice PDF.

What your team should do

1.Bookmark and periodically review the Vicor PCN archive at https://www.vicorpower.com/quality-center/product-change-notices for changes and EOL/discontinuance notices affecting your part numbers.
2.Use the 'Complete the form to receive Vicor Product Change Notices' sign-up on that page to get email notifications of new PCNs.
3.When a notice appears, open the linked PCN PDF (vicorpower.com/documents/pcn/...) to confirm affected model numbers, effective dates, and any last-time-buy / migration instructions.
4.Cross-reference Vicor's affected model numbers against your BOM part numbers, since the public notices are broadcast rather than customer-specific.
5.For questions on a specific notice or to confirm last-time-buy windows, contact Vicor via their Contact Us / Technical Support pages or your Vicor sales representative.
6.Do not rely on distributor PDFs (Mouser/Future) as the authority - treat vicorpower.com as the source of record and use distributor copies only as secondary references.

Access summary

Public archive: Yes - public PCN archive on the Quality Center at vicorpower.com/quality-center/product-change-notices, no login needed to view
Searchable historical notices: Yes - historical notices are listed with dates (PCN/EOL PDFs go back many years, e.g. 2014, 2021, 2023, 2024, 2025), browsable/searchable on the page
Account required: No account required to view PCNs; the site has an SSO/Account login but it is not needed to read the public PCN list or download notice PDFs
Email notification: Yes - the PCN page presents a form: 'Complete the form to receive Vicor Product Change Notices' (email sign-up to receive notices)
Part-number subscription: Not clearly documented - the sign-up appears to be a general PCN subscription form; per-part-number or per-product-family subscription granularity is not confirmed in the captured page content
Customer-specific notification: Broadcast - notices are published publicly to everyone in the archive and are addressed generically ('To Our Customers' / 'Important Notice to our Customers'), not limited to individually affected customers
Distributor involvement: Not clearly documented for PCN delivery - the site has a Distributor Portal (vicor.my.site.com/Distributors), but the PCN archive itself is published directly by Vicor and does not route notifications through distributors

VishayPCN archive · verified Jun 25, 2026＋

Vishay (Vishay Intertechnology, official domain vishay.com) operates a dedicated, searchable Product Change Notification archive at vishay.com/en/quality/pcn-search/ covering PCNs published online from October 1, 2009 onward, with examples spanning 2011-2026. Vishay distinguishes change notices (PCN) from product obsolescence/discontinuance notices (PTN / Product Obsolescence Notification, covering EOL, last-time-buy, and last-time-ship dates). The PCN search is offered as a free subscription service, but you must be registered on Vishay.com AND subscribed for the service before you can use the search.

How notifications work

Vishay self-publishes Product Change Notifications (PCN) and Product Obsolescence Notifications (PTN) on its own site at vishay.com/en/quality/pcn-search/.
PCN covers time-critical product changes (e.g., direct-materials/mold-compound changes, production-location moves, labeling/packing, documentation updates); PTN covers obsolescence/discontinuance with last-time-buy and last-time-ship dates and replacement part numbers where applicable.
The searchable archive holds notices published online from October 1, 2009 onward and supports filtering by product category, brand, classification of change, and date range.
Access to the PCN search is a free subscription service but requires a registered Vishay.com account that has subscribed to the service via the 'Change your Subscriptions' option.
Distributors such as TTI and Mouser republish Vishay PCN/PTN PDFs, but these are third-party mirrors rather than the authoritative Vishay source.

What your team should do

1.Create or use a registered Vishay.com account and enable the PCN subscription via 'Change your Subscriptions' so your team can access the PCN search.
2.Use the official archive at vishay.com/en/quality/pcn-search/ to search historical PCNs/PTNs by product category, brand, classification of change, and date range for your affected Vishay parts.
3.Search the obsolescence (PTN) notices specifically for last-time-buy and last-time-ship dates on EOL parts, and capture any listed replacement part numbers.
4.Periodically re-run the search (or monitor your subscription) since explicit email-push delivery is not clearly documented; do not rely solely on passive email alerts.
5.Cross-check distributor mirrors (TTI/Mouser) only as a supplement, but treat vishay.com as the authoritative source of record for any change or discontinuance decision.

Access summary

Public archive: Yes - a searchable PCN/PTN archive exists at vishay.com/en/quality/pcn-search/, but access to the search itself requires a registered, subscribed Vishay.com account (not fully open/anonymous)
Searchable historical notices: Yes - notices available online from October 1, 2009 onward; search supports filtering by product category, brand, classification of change, and start/end date range
Account required: Yes - registration on Vishay.com plus subscription via 'Change your Subscriptions' is required to use the PCN search; Vishay describes it as a free subscription service to registered customers
Email notification: Not clearly documented - the official page frames PCN as a subscription service and references 'Change your Subscriptions,' but explicit email-push delivery of new PCNs is not clearly stated on the official page
Part-number subscription: Not clearly documented - the search supports filtering by product category and brand; per-part-number or product-family subscription granularity is not clearly described on the official page
Customer-specific notification: Not clearly documented - the official archive appears broadcast/general to all subscribers; no statement that notices are restricted only to affected customers
Distributor involvement: Not officially required - Vishay self-publishes PCNs/PTNs on vishay.com; distributors (TTI, Mouser) independently mirror Vishay PCN PDFs, but those are third-party copies, not the official source

WinbondNotification-policy page · verified Jun 25, 2026＋

Winbond (winbond.com) documents its change/discontinuance NOTIFICATION COMMITMENTS on its official Product Longevity Program (WPLP) page, but does NOT host a public, searchable PCN/PDN archive on its own domain. The page states Winbond will "notify customers" and defines lifecycle timelines (standard JEDEC conversion/discontinuance for standard parts; an extended 2-year window of 12 months last-time-buy + 12 months last-time-ship for enrolled PLP/automotive parts), with notices delivered through sales-rep/distributor channels rather than a self-serve portal or email-subscription archive.

How notifications work

Winbond's official Product Longevity Program (WPLP) page commits that Winbond will 'notify customers and work in supporting an uninterrupted business flow' when a part number change or discontinuance occurs.
Standard products follow standard JEDEC conversion and discontinuance timelines; products enrolled in the Product Longevity Program (all automotive parts, plus opted-in non-automotive parts) get an extended 2-year conversion window: 12 months last-time-buy + 12 months last-time-ship (longer may be available), with up to 7-year roadmap visibility (3-year for standard parts).
PCN/PTN notices are distributed through sales and distributor channels rather than a public self-serve archive; the documents themselves instruct customers to contact their Winbond sales representative with questions.
Winbond's customer-facing PCN/PTN PDFs (e.g. packing changes, part replacements like W25Q64DW to W25Q64FW) are found in the wild only on distributor sites (Mouser, Digi-Key, Anglia, Chip1Stop), not on winbond.com.
Winbond's own site references PCN ('Process/Product Change Notice') only as a SUPPLIER-side management principle on its Sustainable Supply Chain page — not as a customer-facing notification archive.
Winbond operates a login-gated Partner Portal (partnersso.winbond.com) and a general sign-in (winbond.com/hq/signin); whether PCN delivery/subscription happens there is not publicly documented.

What your team should do

1.Establish a direct relationship with your Winbond sales representative or FAE and request to be added to their PCN/PTN/EOL distribution list for your specific part numbers — this is the primary documented channel.
2.If you buy through an authorized distributor (Mouser, Digi-Key, Avnet, Anglia, etc.), enroll in that distributor's PCN/change-notification alert service, since distributors receive and archive Winbond PCN/PTN PDFs.
3.For parts requiring long lifecycle support, ask your sales rep about enrolling non-automotive parts in the Winbond Product Longevity Program to obtain the extended 2-year (12mo LTB + 12mo LTS) window and up to 7-year roadmap visibility.
4.Check whether your organization has access to the Winbond Partner Portal (partnersso.winbond.com) and confirm with your rep whether change notices are posted there for your account.
5.Do not rely on winbond.com for a self-serve searchable PCN history — there is no public archive; maintain your own internal log of received PCN/PTN documents (keep the distributor-hosted PDFs).
6.Use Winbond's Technical Support inquiry form (winbond.com/hq/support/technical-support) only as a fallback for ad-hoc questions, not as a notification subscription mechanism.

Access summary

Public archive: No public PCN/PDN archive found on winbond.com; actual PCN/PTN PDFs surface only via distributors (Mouser, Digi-Key, Anglia, Chip1Stop)
Searchable historical notices: Not clearly documented
Account required: No public archive to view; Winbond operates a login-gated Partner Portal (partnersso.winbond.com) and sign-in page, but PCN-notification features behind it are not documented
Email notification: Not clearly documented
Part-number subscription: Not clearly documented
Customer-specific notification: Notices are delivered to affected customers via their assigned Winbond sales representative; PCN/PTN documents direct customers to contact their sales rep

§ Coverage

How PCNshark supports manufacturer notices

PCNshark centralizes and processes the notices your team receives. It is important to be clear about what that does and does not include.

Customer-provided notices

Forward notification emails or upload PCN documents you receive from manufacturers and distributors. PCNshark stores each one, extracts the affected parts and dates, and matches them to your BOMs.

External-source discovery

PCNshark may discover notices through supported external sources, but coverage varies by manufacturer, distributor, part, and source availability. It is supplemental, not a guarantee.

Customer portal restrictions

Some manufacturers provide notices only through authenticated customer portals or purchasing relationships. PCNshark cannot automatically retrieve private notices unless an authorized integration or user-provided workflow exists.

No external source provides complete coverage of every manufacturer, part number, customer-specific notice, or distributor notification. Teams should maintain their manufacturer and distributor subscriptions and use PCNshark to centralize and process the notices they receive.

§ Workflow

A more reliable manufacturer PCN workflow

Because no single channel is complete, the most dependable approach combines manufacturer and distributor subscriptions with a central place to process what arrives.

01Maintain current accounts with key manufacturers.
02Subscribe to available PCN and product notifications.
03Confirm that authorized distributors have the correct contacts.
04Route supplier and distributor notices to a shared inbox.
05Forward emails or upload PDFs into PCNshark.
06Extract affected MPNs and critical dates.
07Match the notice against active BOMs.
08Assign an internal owner.
09Record the decision and required follow-up.

Which manufacturer subscriptions does your BOM require?

A single BOM may contain parts from dozens of manufacturers, each with a different PCN process. PCNshark helps identify the manufacturers represented in your BOM and centralize the notices your team receives.

§ FAQ

Frequently asked questions

01Where can I find manufacturer PCNs?＋

It varies by manufacturer. Some publish a public, searchable PCN archive (for example onsemi, Microchip, Renesas, and Lattice); others provide only a notification policy page and send notices to affected customers directly (for example Texas Instruments, STMicroelectronics, and Micron). Authorized distributors often host and forward PCN PDFs as well. Use the matrix above to find each manufacturer's official source.

02Do all manufacturers provide public PCN archives?＋

No. Several do, but others publish only a notification policy page, gate the archive behind an account, or notify affected customers without a public archive. Where we could not confirm a public archive from official materials, this guide says "Not clearly documented" rather than guessing.

03Do I need an account to receive PCNs?＋

Often, to subscribe. Many manufacturers let you view individual notices without an account but require a free account (such as myTI, My NXP, myAnalog, or My Renesas) to subscribe to email alerts. Some archives are entirely account-gated.

04Will manufacturers notify every user about every product change?＋

No. Notices are commonly targeted to affected customers of record — often those who purchased the part within a recent window, such as 24 months — or to users who have subscribed. Without a purchasing relationship or subscription, you may not be notified directly.

05Do distributors forward manufacturer PCNs?＋

Frequently. Authorized distributors (Digi-Key, Mouser, Avnet, TTI, Farnell, and others) receive manufacturer notices and forward or host them for their customers. If you buy through distribution, confirm your distributor will forward PCNs to you.

06Can PCNshark access private manufacturer portals?＋

No. PCNshark cannot automatically retrieve notices from authenticated customer portals or purchasing relationships unless an authorized integration or a user-provided workflow exists. You forward the emails or upload the PDFs you receive, and PCNshark centralizes and processes them.

07Can I upload PCNs that I receive by email?＋

Yes. Forward notification emails to your dedicated PCNshark address or upload PCN PDFs. PCNshark stores each one and extracts the affected parts, change type, and dates for your team to review.

08Can PCNshark match a manufacturer PCN against my BOM?＋

Yes. Matching the affected part numbers from a notice against your active BOMs to identify impacted products is a core PCNshark workflow.

09Does PCNshark provide complete coverage of every manufacturer?＋

No — and no platform should claim it does. There is no single source that covers every manufacturer, every part, every customer-specific notice, and every distributor channel. Maintain your manufacturer and distributor subscriptions, and use PCNshark to centralize and process the notices you receive.
