Subject: Reliability Prediction of FET, Bipolar, Diodes, etc.
1. Are the reliability prediction results big different between using MIL-HDBK-217F notice2 and using Bellcore? I just try MIL. Using Bellcore can get "better" MTBF? 2. Except the above two, are there any other methods to predict the reliability of electronic components? Thanks in advance! Kang

MIL-HDBK-217 was developed to predict the reliability of military systems, Bellcore was developed to predict the reliability of Bell Labs equipment. The main concepts between MIL-HDBK-217 and Bellcore are similar, but Bell Labs modified the equations from MIL-HDBK-217 to better represent what their equipment was experiencing in the field. Depending on your system and its application a Bellcore prediction may or may not yield a higher MTBF. Other electronic reliability prediction methods are: SAE Reliability Prediction Method, Honeywell’s Reliability Prediction Method, Physics of Failure, CNET RDF 93, RAC’s System Reliability Assessment Method PRISM , and PredIT.
