Effective Management of Semiconductor Obsolescence in Automotive ECU Manufacturers

The rapid evolution of semiconductor technology poses a significant challenge for the automotive industry, particularly in managing the lifecycle of electronic components used in Electronic Control Units (ECUs). While automotive products typically require a 15-year service life, semiconductor components often become obsolete within 7–10 years, creating a critical gap that threatens both supply chain stability and product sustainability. This issue is further exacerbated by the rising number of End-of-Life (EOL) notices from semiconductor manufacturers, along with ongoing geopolitical policies. Without effective lifecycle management, ECU manufacturers face production delays, costly redesigns, and compliance risks with stringent functional safety standards mandated by Original Equipment Manufacturers (OEMs). This paper examines proactive and mitigative strategies for addressing semiconductor obsolescence risks, including enhanced component lifecycle monitoring during the development phase, database enrichment, multi-sourcing component strategies, and risk-sharing agreements with suppliers and customers. By implementing these measures, ECU manufacturers can improve supply chain resilience, ensure compliance with safety and reliability standards, and reduce the financial impact of semiconductor obsolescence. The findings of this study highlight the importance of a structured approach to lifecycle management, which can significantly enhance the sustainability and reliability of automotive electronics.
