Your question cannot be properly answered based on the information provided. Knowing the device type is not sufficient to determine a devices failure rate. Additional information concerning device quality level, use environment, and in-circuit stresses is required. The RAC has a reliability prediction tool PRISM that can be used to predict the failure rate for a device. Information and a downloadable demo for PRISM can be found at .
