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!

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.
