PCN (Product Change Notification) Response Template
Manufacturers send product change notifications constantly, and a missed one can change the parts on your line without anyone deciding to accept it. This template gives engineering, quality and purchasing one place to record the review and the decision.

PCN Review and Response
Company: Acme Electronics Ltd Manufacturer: Example Semiconductor PCN number: PCN-20260918-A Date received: 2026-09-25 Effective change date: 2027-03-01 Change type: Assembly site change
Affected parts and products
Parts: ABC1234-QFN32 ABC1234-QFN32-T
Products and assemblies affected: Controller board rev C, Gateway unit rev B
Impact assessment
Assembly moves to a new site with the same package outline. Solder reflow profile and MSL rating unchanged per notice. Need samples to confirm board-level reliability.

Decision
Decision: Accept after sample evaluation
Actions

| Notify customer if required | |||
| Place last time buy if applicable |
Many manufacturers follow JEDEC J-STD-046 style customer notification. Check the response window in the notice itself: silence is often treated as acceptance after a stated period. This is a working template, not a contractual document.

How to use it
When a notice arrives, create one response per PCN number. Record the manufacturer, the effective date and the type of change, then list every affected part number and every product that uses it. Where-used in the ERP is the quickest way to find products. Complete the review checklist, pick a decision and assign actions with owners. Export it to PDF and file it with the notice so the decision is auditable.
- Log the response deadline on day one
- Use where-used to find every assembly, not only the active ones
- Attach the manufacturer notice and any qualification data
- Update the approved vendor list when the decision is accepted
Reading the change type
Not every change carries the same risk. A marking change rarely affects the product, while a wafer fab, die revision or package material change can affect performance, reliability or soldering behavior. End of life notices start a different process: last time buy and redesign. For regulated or high reliability products, even a benign change may need customer notification or requalification under your quality agreement.
Deciding and documenting
Accept without action only if the notice shows form, fit and function are unchanged and your contract does not require approval. If you ask for samples, set a date by which you will decide so the change date does not pass. If you reject, state the reason and request an extended supply or last time buy window. In every case, record who decided, when and on what evidence.
Common mistakes
Teams often file notices in a shared mailbox with no owner, miss notices sent to a distributor rather than to them, and forget stock that was built to the old version. Also check that the ERP item master tracks revision or date code if your customers need to know which version shipped.
Frequently Asked Questions
What is the difference between a PCN and a PDN?
Terms vary by manufacturer. PCN usually means a change notification with a stated effective date, while PDN or PDN-style notices may announce discontinuance. Treat any notice as a trigger for review and read the action it asks of you.
Does silence mean acceptance?
Often yes. Many notices state that if no objection is received within a set period, the change is considered accepted. Check the notice and your agreement, and respond within the window if you object.
Who should sign off the response?
At minimum the component or design engineer and quality. Purchasing signs where supply or last time buy is involved. High reliability programs may add the program manager or customer representative.
Do I need a response for every PCN?
You need a record for every PCN that touches a part you buy or hold. A short entry for a trivial change is fine, as long as someone with authority reviewed it and the file is retrievable.
Netray can help route manufacturer notices to the right owner and match them against your item master and where-used data, while keeping the decision with your engineers.
