Change Management
Industry standards dictate the timeline and documentation requirements for notifying customers when a semiconductor product is modified or removed from active production. The jesd48 standard provides a uniform procedure for product discontinuance and product change notification in the electronics market. It ensures that purchasers have sufficient time to evaluate the impact of a change and to secure a final supply of the original part if necessary.
This standard applies to all manufacturers of solid state products, creating a predictable environment for supply chain managers. The process begins when the supplier decides to end the life of a component or change its manufacturing location. By standardizing the notification format, the industry reduces the administrative burden on customers who must track thousands of individual part numbers.
Notification Timeline
Requirements for the timing of an announcement are strictly defined to allow for a transition period of at least twelve months from the date of the notice. The jesd48 protocol mandates that a manufacturer must provide a minimum of six months for the customer to place a final order after the discontinuance notice is issued. Following the close of the order window, the supplier must allow another six months for the final shipments to be completed.
This twelve month cycle is the industry benchmark for managing the obsolescence of critical hardware. If a manufacturer fails to meet these timelines, they risk disrupting the production lines of their customers and damaging their long term commercial relationships. The standard also covers the information that must be included in the notice, such as the reason for the change, the last buy date and the recommended replacement part.
Documentation Standard
Notification packages must be delivered in a clear and standardized format to ensure that all relevant stakeholders can quickly assess the situation. The document specifies that the notice should include the supplier name, the part number, the description of the change and the impact on the form, fit or function of the device. If the change involves a new manufacturing process, the supplier is expected to provide qualification data and samples for the customer to test.
This transparency allows the customer to determine if the new version is a drop in replacement or if a redesign of the printed circuit board is required. Proper use of the jesd48 standard prevents surprises in the supply chain and allows for a more orderly transition between product generations.
Lifecycle Transition
Management of the phase out process is a shared responsibility between the component vendor and the system integrator. While the supplier must follow the notification rules, the customer must act quickly to forecast their remaining needs and secure the necessary budget for a last time buy. The standard provides the framework for this negotiation but does not dictate the commercial terms such as price or payment schedule.
In many cases, the end of a product life cycle triggers a search for alternative sources or a full system redesign. The standard remains the primary defense against the sudden unavailability of critical electronic components in industrial and automotive applications.
