Dear RAC, What electronic components PRISM does not support, e.g., Inductor, Oscillator? Is there a way to import failure data from other software (Relex) to compensate for these 'not-supporting' components? Thanks

PRISM Component models (or PRISM RACRates models) are available for capacitors, diodes, integrated circuits (monolithic), resistors, software, thyristors, transistors, and software. Components not directly modeled by RACRates models are covered by allowing the insertion of RAC component or assembly failure rate data, or user-defined component or assembly failure rates, into the reliability prediction. The RAC failure rate data included in the PRISM tool is derived directly from RAC Electronic Parts Reliability Data (EPRD) and Nonelectronic Parts Reliability Data (NPRD) publications. Component types covered by these supplemental datasets include an extensive directory of electrical, mechanical, and electromechanical components. The combination of failure rate models and appropriately weighted empirical data allows for a complete system reliability assessment.
