Chipset End of Life Notices and the Redesign Clock
A silicon end-of-life notice demands an immediate audit of last-time-buy volumes against redesign lead times to prevent production gaps during recertification.
Jesd48c
Meaning
Industry standards define the requirements for informing customers about the retirement of electronic components to ensure a predictable end of life process. The jesd48c standard provides a framework for the content of these notifications and the timing of the transition. By following this protocol, suppliers help their clients manage the obsolescence of parts without interrupting their own manufacturing schedules.
Notice Timeline
Manufacturers are expected to provide at least six months of notice before the final order date for a component. This period allows the buyer to evaluate their future needs and secure the necessary capital for a final purchase.
Supplier Obligation
Clear communication about the replacement part or the lack of a direct substitute is a requirement under this standard. These details prevent sudden disruptions in the production of the final product and allow for the qualification of new vendors.
Transition Strategy
Engineering departments use the information provided in the alert to begin the qualification of alternative parts from different suppliers. This process includes testing the electrical compatibility and physical footprint of the new component to ensure it meets the original design specifications. Without the structure provided by jesd48c, companies would face higher risks of production delays and component shortages that could damage their reputation with end users.
