Legacy systems are integral to the aerospace industry, offering proven reliability and stability. However, as technology advances, component obsolescence increasingly threatens these systems, making preservation essential.

Rochester Electronics plays a crucial role in supporting legacy systems in the aerospace industry through authorized distribution, licensed manufacturing, and comprehensive replication services. These services allow companies to maintain these systems without costly redesign or recertification.

Component obsolescence is a result of various factors, including changes in manufacturing processes, evolving silicon technologies, and economic factors. These challenges can lead to significant disruptions in supply chains, increased costs, and compatibility issues. In the case of avionics systems, the certification process is notoriously rigorous, involving extensive testing, validation, and documentation to ensure that each component and system meets the necessary safety and performance criteria. Unfortunately for designers, most changes to avionics systems necessitate re-certification for compliance. Using legacy systems that have already undergone certification is far more cost-efficient than a complete redesign and a significant reason why preserving these systems is so important.
