Interchangeability:

Thermal and Performance Needs: The FP75R12KE3, with its enhanced thermal performance, is better suited for high-stress conditions compared to the FS75R12KT3. However, the FS75R12KT3 can still be used in applications with adequate thermal management.
Application Specificity: Both modules are suitable for general-purpose inverters and motor drives, making them largely interchangeable in these contexts. However, for more demanding thermal environments, the FP75R12KE3 would be the preferred choice.
