Subject: Status of Additional RACRates Models
The 2001 AR&MS tutorial notes on PRISM includes a statement "additional RACRates models are under development". Can you provide the status? What specific models are in process and are there estimated completion dates? I prefer to use RACRates models (rather than the fixed failure rates from the EPRD/NPRD databases) to more accurately reflect the thermal and operating conditions unique to our applications. However, a significant number of parts used in our designs are not covered by the existing RACRates models. This is considered a limitation of PRISM vs. MIL-HDBK-217FN2 which includes more models, albeit outdated. Appreciate the update!
