Avoiding DO-254 Events: Major/Minor Change Classification

SPONSORED BY:

Rochester Electronics documents a design replication process that develops form, fit and functionally equivalent devices which falls under a DO-254 minor change classification.

Boeing and Airbus have very strict guidelines for when a design change can be classified as a minor or major change. Boeing’s DO-254 standard is their guideline. Semiconductor products are subjected to obsolescence, and there is a need to create a form, fit and functionally equivalent device for long-life systems. This Rochester Electronics white paper outlines the key features of a design replication approach and establishes sufficient evidence that the proposed change can be classified as a minor change event for DO-254.
