Learn how to evaluate software for PCN intake, affected-part extraction, BOM matching, ownership, deadlines, and resolution tracking.
Available on Starter and Team. A payment method is required.
A shared inbox and spreadsheet can work when notice volume, BOM count, and product complexity are low. A dedicated workflow becomes valuable when the process starts depending on repeated manual cross-referencing, informal ownership, and individual memory.

The same three steps a focused PCN tool runs every time a notice arrives: ingest, extract and review, then match to your BOMs and assign an owner.
Forward an email or upload the PDF; the original notice is preserved.

Affected MPNs, notice type, and key dates are extracted and a reviewer confirms them.

Affected BOMs and products surface, each assigned to an owner with a tracked status.

PCNshark does not replace engineering, quality, sourcing, or regulatory judgment. It organizes the notice, BOM impact, deadlines, ownership, and supporting record so the responsible team can make and document the decision.
A semiconductor manufacturer issues a product discontinuation notice affecting 142 manufacturer part numbers. The notice includes a last-time-buy deadline and a proposed replacement. The receiving team must determine whether any affected part is used across its active products and establish who owns the response.

PCN management software helps teams convert supplier product-change notices into structured, BOM-specific actions. It typically centralizes notice intake, extracts affected parts and dates, identifies impacted products, assigns owners, and tracks the response through closure.
This guide covers what to look for, how PCN-to-BOM matching works, which data fields matter, and how to compare a focused PCN tool, a broader platform, and your current process — with a feature-evaluation table and a downloadable checklist you can use in a review.
A product change notice (PCN) is a formal notice from a component manufacturer that a product is changing — its process, materials, packaging, or form, fit, and function. Semiconductor suppliers issue PCNs under the JEDEC standard J-STD-046 (Customer Notification of Product/Process Changes).
A related notice, the product discontinuance notice (PDN), tells you a product is being discontinued; discontinuance notices follow JEDEC J-STD-048. A PDN usually carries a last-time-buy (LTB) date — the deadline to place final orders — and a last-ship date.
PCNs arrive as unstructured PDFs and emails, in inconsistent formats, from many manufacturers and distributors, on no shared schedule. A single product can depend on hundreds of parts across several BOMs and revisions, so deciding whether a given notice matters means cross-referencing it against everything you build.
Volume and timing make it worse: notices pile up, deadlines are easy to miss, and supplier compliance with notification windows is uneven. The work is repetitive, detail-sensitive, and unforgiving — exactly the kind of process that benefits from software.
Notices reach teams through several fragmented channels, which is part of why they are hard to track:
Most teams start by forwarding notices to a shared inbox and tracking them in a spreadsheet. It works until volume grows. Then the cracks show: notices get read and forgotten, the spreadsheet drifts from the real BOMs, no one owns a given notice, and last-time-buy dates slip past unnoticed.
The deeper problem is traceability. When an auditor, a customer, or your own team asks “what did we do about this change, and when?”, an inbox and a spreadsheet rarely give a clean answer.
A focused PCN tool should take a notice from arrival to resolution. At minimum that means:
The core of PCN management is connecting a notice to what you actually build. The software normalizes the manufacturer part numbers on the notice, compares them against the parts on your active BOMs (accounting for formatting differences and revisions), and surfaces the products and assemblies that contain a match.
Good matching is conservative about false negatives — a missed match is a missed deadline — and transparent about why a match was made, so an engineer can confirm it quickly rather than trusting a black box.
PCNshark is a focused PCN tool. You forward or upload a notice; it extracts the affected manufacturer part numbers, change type, and dates (including from scanned PDFs); it matches them against your active BOMs to show which products are affected; you assign an owner and track follow-up; and every notice, deadline, and decision is retained as a reviewable record.
It is intentionally focused: PCNshark does not try to be a component search engine or a compliance platform. It is the operating layer for acting on change notices — and for the decision that follows, each part carries an organization-wide component record with its lifecycle status and evidence, alternate recommendations (Team plans and above), distributor sourcing estimates, datasheets, and decision history. It runs on its own, or alongside a broader component-data provider.
A broad platform supports component research and external intelligence, while PCNshark manages the internal workflow after a notice is received.
Side-by-side comparisons: PCNshark vs. SiliconExpert · PCNshark vs. Z2Data · Octopart vs. PCNshark
Whatever tool you use, these are the fields worth capturing from each notice — they drive matching, deadlines, and follow-up.
Several kinds of tools touch this problem. None is universally “best” — the right choice depends on your scope.
Purpose-built for the PCN workflow: intake, extraction, BOM matching, ownership, and an auditable record. PCNshark is one option here.
Wide platforms (e.g. SiliconExpert, Z2Data) that include PCN/lifecycle data alongside component search, compliance, and supply-chain-risk analytics.
Manage product and item data and can store change records, but are not built to ingest and interpret incoming supplier PCNs.
Tools like Octopart help find parts and compare sourcing and lifecycle status, and point users to manufacturer PCN alerts, rather than running a PCN-to-BOM workflow.
The common starting point: a shared inbox and a tracker. Workable at low volume; fragile as notices and BOMs grow.
Custom scripts or databases tailored to one team's process — flexible, but a maintenance burden to keep accurate.

PCNshark is designed around the core operational requirements in this checklist: notice intake, document extraction, human verification, BOM matching, ownership, deadline tracking, collaboration, and review history.
It is not intended to replace broad component search, compliance intelligence, predictive lifecycle data, or supplier-risk platforms.
A starting point you can adapt. Copy, print, or download it and tailor the owners to your organization.
| Stage | Suggested owner | Required output |
|---|---|---|
| Intake | Component or supply-chain team | Notice captured and preserved |
| Extraction | System plus reviewer | Verified MPNs, dates, and change details |
| Impact review | Engineering or component team | Affected BOMs and products confirmed |
| Response selection | Cross-functional owner | Accept, purchase, qualify alternate, or redesign |
| Closure | Program, quality, or component owner | Decision and evidence recorded |
Ownership varies by company, product, regulatory environment, and organizational structure.
The SOP defines the process. PCNshark provides the operating record: the original notice, extracted information, BOM exposure, assigned owner, deadline, status, and final decision.
There's no universal number of PCNs at which a spreadsheet fails. Watch for these signs that your process has outgrown it:

Start your 14-day trialOwnership models vary by company; these are common ways teams divide a PCN response.
Review affected MPNs, understand the change, confirm BOM exposure, and coordinate alternate qualification.
Track last-time-buy and last-ship dates, evaluate purchasing exposure, and coordinate supplier follow-up.
Preserve the source notice, review evidence, qualification impact, and documented disposition.

PCNshark earns trust through how it works — not through fabricated metrics or logos.
We state plainly what PCNshark covers — the notices your team forwards or uploads — and never claim complete coverage of every manufacturer or portal. It does not crawl notice feeds on your behalf.
Extracted MPNs, change types, and dates are reviewed by a person before anyone acts on them.
The source document stays attached to the record, so a reviewer or auditor can always check the original.

Start a trial, upload a BOM, and process a notice without a mandatory sales call.
Use PCNshark standalone or as the operational layer next to a broader component-data platform.
