Introduction

Product Change Notifications (PCNs) are formal notices sent to manufacturers to inform them of changes in a product, such as modifications in design, materials, or manufacturing processes. These notifications help deliver the intended product and facilitate system updates for affected components or applications.

Why are PCNs Issued?

In the electronics industry, PCNs are typically issued by Original Component Manufacturers (OCMs) or Original Equipment Manufacturers (OEMs) to notify customers of changes that may affect product performance, compatibility, or ease of use. Manufacturers or suppliers typically issue PCNs when product design, materials, manufacturing techniques, or regulations governing performance criteria change.

Industry Standards:

JEDEC: Offers standards for microelectronics, including J-STD-046 and J-STD-048, which guide OCMs and OEMs in notifying customers about product changes and discontinuations.
