PCNshark
Component Obsolescence Management

Know what is exposed when a component goes EOL — and what to do next

An end-of-life notice is rarely one decision. It is a chain of them: where the part is used, how much exposure is active, whether a last-time buy is warranted, what a replacement would cost to qualify, and whether any of it needs a redesign.

PCNshark connects the EOL evidence to BOM usage, program impact, alternate candidates, and current sourcing conditions — and preserves the documented response on an organization-wide component record. The lifecycle status, the evidence behind it, the alternates evaluated, the sourcing estimates consulted, and the final decision stay together instead of scattering across inboxes and spreadsheets.

Available on Starter and Team. A payment method is required.

Scope

PCNshark organizes obsolescence evidence, exposure, and the decision workflow. Engineering owns qualification, sourcing owns the buy, and the team makes every lifecycle decision — nothing is decided automatically.

Is obsolescence risk managed — or discovered?

An EOL notice creates multiple decisions

The notice itself is the easy part. What follows is a chain of questions, each owned by a different person, each needing data that usually lives somewhere else:

Each question is answerable. The failure mode is that the answers live in different tools, the deadline lives in a calendar, and the decision lives in an email. PCNshark keeps the chain on one component record.

§ From EOL signal to recorded decision

The obsolescence scramble, structured

The same EOL event, handled two ways. The response paths — last-time buy, qualify the manufacturer's recommended replacement, qualify a functional alternate, redesign, or accept and monitor — are chosen by the team. PCNshark organizes the evidence and context; it does not choose a response.

Manual scramble
  1. EOL letter lands in one inbox
  2. Part searched across BOM spreadsheets
  3. Stock checked distributor by distributor
  4. Replacement debated in a chat thread
  5. LTB date entered in someone's calendar
  6. Decision made in a meeting, recorded nowhere
  7. Same questions re-asked months later
With PCNshark
  1. Capture the EOL evidence on the part
  2. Set the lifecycle status, evidence attached
  3. See where-used: BOMs, revisions, programs
  4. Review open impacts and per-line decisions
  5. Evaluate alternates (Team plans and above)
  6. Refresh distributor sourcing estimates on demand
  7. Record the decision — owner, rationale, evidence

One component record carries the lifecycle status, the evidence behind it, the exposure, the deadline, the alternates evaluated, the sourcing context consulted, and the decision — so the organization answers each obsolescence question once.

Two kinds of alternate signal, kept distinct

When a part goes EOL, PCNshark surfaces replacement candidates two ways — and never blurs the difference between them. Both are available on Team plans and above.

Where it comes from
Manufacturer-recommended replacement

Extracted from the EOL notice itself

Spec-ranked functional candidates

Ranked by specification similarity across candidate parts

What it tells you
Manufacturer-recommended replacement

The successor the manufacturer names

Spec-ranked functional candidates

A match percentage and the specific specs that differ

What it is
Manufacturer-recommended replacement

The manufacturer's suggested starting point

Spec-ranked functional candidates

A prioritization signal for engineering evaluation

What it is not
Manufacturer-recommended replacement

Not a verified drop-in replacement

Spec-ranked functional candidates

Not a qualification result

Who decides
Manufacturer-recommended replacement

Engineering, after review and qualification

Spec-ranked functional candidates

Engineering, after review and qualification

Alternate recommendations help prioritize engineering evaluation. They do not replace qualification. PCNshark never certifies a part as drop-in compatible.

What PCNshark adds when a part goes EOL

Lifecycle evidence, attached

EOL information rarely arrives one way. A PCN, a PDN, an EOL letter, a manufacturer email, a distributor listing, a supplier call, an internal sourcing observation — whatever form the evidence takes, attach it to the lifecycle status so the decision has a source, not a rumor.

Where-used blast radius

One view of everything the part touches: which BOMs use it, at which revisions, across which programs, with which impacts still open. Exposure stops being a spreadsheet-search exercise.

Sourcing context on demand

Stock, MOQ, price breaks, estimated lead time, authorized vs. independent availability, and a market median at 1k across roughly 15 distributors. Distributor data, refreshed on demand — estimates, not quotes.

Decisions that stick

Set a lifecycle status manually with the evidence behind it. When later evidence conflicts, PCNshark flags the conflict for review — a manually reviewed decision is never silently overwritten.

Part-level decision history

Who changed the status, when, from what to what, why, and on what evidence. The next engineer who hits this part inherits the reasoning, not just the conclusion.

Datasheets on the record

Find and attach the datasheet from available sources, or upload your own copy — so the evaluation of an aging part or its candidate replacement starts from the document, not a search.

§ Worked example

Example: an EOL notice and its blast radius

An illustrative end-of-life notice for a widely used microcontroller, and what the component record shows once the notice is captured. Illustrative data — every value is invented.

EOL notice
Affected MPN
STM32F407VGT6
Lifecycle change
NRND → EOL announced
Last-time-buy date
March 31, 2027
Last-ship date
September 30, 2027
Suggested replacement
STM32H563ZIT6
PCNshark on the component record
  1. MPN matched against monitored BOMs
  2. Where-used and program exposure surfaced
  3. Manufacturer-recommended replacement extracted from the notice
  4. Functional candidates ranked by spec similarity (Team plans and above)
  5. Distributor sourcing estimates refreshed on demand
  6. Owner assigned; LTB deadline tracked
Blast radius and response context
BOMs using this part
12
Programs affected

Recommended replacement
STM32H563ZIT6 — 94% spec match
Distributor stock (est.)
18,420
MOQ / median @1k (est.)
100 / $4.82
Estimated lead time
14 weeks

Illustrative data — all values invented. Sourcing figures are distributor estimates refreshed on demand, not quotes or availability guarantees. The 94% spec match prioritizes evaluation; qualification remains with engineering.

PCNshark does not make lifecycle, qualification, or purchasing decisions automatically. Sourcing figures are distributor estimates refreshed on demand — not quotes, and not availability guarantees. Engineering owns qualification; sourcing owns the buy.

Before the last-time-buy deadline

A last-time buy is an engineering-and-sourcing coordination event, not just a purchase. A practical checklist of what the team should have in hand — copyable and printable, no email required.

Your selections stay in your browser — nothing is uploaded, and no email is required to copy, print, or download.

PCNshark keeps the deadline, the exposure, the sourcing estimates, the alternate candidates, and the recorded decision on the same component record — so the LTB conversation starts with data instead of a document hunt.

§ Roles

A last-time buy is a coordination event, not a purchase order

The deadline is shared; the work is not. Exact ownership varies by company, product, and quality system — PCNshark records who owns what so the deadline does not become an argument.

Component engineering

Assess the technical impact, evaluate the recommended replacement and spec-ranked candidates, and own qualification — or the call that a redesign is the better path.

Sourcing / supply chain

Track the LTB and last-ship deadlines, weigh stock, MOQ, and price-break estimates against expected demand, and execute the buy the team decides on.

Quality

Define the qualification and reliability requirements a replacement must meet, and the evidence the decision record must carry.

Program / product owners

Say which programs carry the exposure, how long each remains in production, and what schedule risk a redesign would introduce.

§ FAQ

Frequently asked questions

01What counts as obsolescence evidence in PCNshark?
Whatever your team actually receives: a PCN or PDN, an EOL letter, a manufacturer communication, a distributor notification, notes from a supplier call, or an internal sourcing observation. Attach the document or note to the lifecycle status so the decision carries its source.
02Does PCNshark discover EOL notices automatically?
No. PCNshark works from the notices your team forwards or uploads — it does not crawl manufacturer or distributor portals on your behalf. Maintain your manufacturer and distributor subscriptions; PCNshark handles everything after the evidence lands.
03Can I mark a part obsolete without a formal notice?
Yes. Manual lifecycle decisions are supported — set the status, attach the evidence, and record the rationale. If later evidence conflicts with a manually reviewed decision, PCNshark flags the conflict for review; it never silently overwrites the decision.
04What does the blast radius show?
Everything the part touches in your workspace: the BOMs that use it, the revisions involved, the programs affected, and any impacts still open against it — so exposure is a lookup, not a research project.
05How do alternate recommendations work?
Two ways, kept distinct. The manufacturer-recommended replacement is extracted from the notice itself; functional candidates are ranked by specification similarity with a match percentage and the specs that differ. Both are available on Team plans and above. Neither is an approval — alternate recommendations help prioritize engineering evaluation, they do not replace qualification.
06What sourcing data does PCNshark show?
Stock, MOQ, price breaks, estimated lead time, authorized vs. independent context, and a market median at 1k, drawn from roughly 15 distributors. Distributor data, refreshed on demand — figures are estimates, not quotes, and never a guarantee of availability or lead time.
07Can PCNshark calculate my last-time-buy quantity?
No. PCNshark does not do demand planning. It gives the team the deadline, the exposure, and the sourcing estimates; engineering, sourcing, and program owners decide the quantity and record the rationale.
08Can different BOM lines get different decisions?
Yes. Impact triage supports per-line decisions and exclusions — one program may take a last-time buy while another qualifies the replacement — and manufacturer mismatches are flagged so a same-MPN, different-manufacturer line is not resolved by accident.
09Is there an audit trail for lifecycle decisions?
PCNshark keeps a part-level decision history: who changed the status, when, from what to what, why, and on what evidence. It is scoped to the component record — it is not a workspace-wide audit log.
10How does this hand off to our PLM or ERP?
Manually, by design. PCNshark produces a BOM-impact CSV and a PDF impact report that the change owner attaches when opening a change in the PLM or ERP system. There is no automatic sync, and PCNshark does not replace either system.
11Can PCNshark find datasheets?
Yes. It can find and attach a datasheet from available sources, or you can upload your own copy — for the aging part and for candidate replacements alike.
12What happens after the 14-day trial?
Starter and Team include a 14-day trial and require a payment method. After the trial, the plan continues unless you cancel. Scale begins as a paid subscription rather than a trial.

Turn obsolescence into a managed decision.

Capture the EOL evidence, see the blast radius across BOMs and programs, weigh alternates and sourcing estimates, and record the decision where the next engineer will find it. The notice is the trigger; the component record is where the response lives.

Starter and Team include a 14-day trial. A payment method is required. Scale begins as a paid subscription. Engineering keeps qualification. Sourcing keeps the buy. PCNshark keeps the record.
