How to Choose Semiconductors for a Product Expected to Last 15 Years
Designing an electronic product for a 12- to 15-year life changes the meaning of “best component.” Peak performance and the lowest unit price still matter, but they compete with product longevity, software continuity, manufacturing stability, qualification, traceability, and the cost of future redesign. This is common in industrial controls, building automation, energy systems, transportation, laboratory instruments, and repairable equipment. The product may stay in production for years and remain in the field even longer. A semiconductor selected today may need to support manufacturing, warranty, service stock, and regulatory records well into the next decade. No supplier can remove all uncertainty from that horizon. A good design process makes the uncertainty visible and creates options before they are urgently needed. Define the Required Support Window “Fifteen-year product” can mean several things. Convert it into dates and quantities. For example: design and qualification: 18...
