Is there a pin-compatible replacement for DFE252012P-4R7M=P2?

Yes, several parts like DFE252012PD-4R7M=P2 share the same 2520 package and pinout. However, key electrical parameters like current ratings may differ, requiring engineering review before use.

What risks should I check before replacing DFE252012P-4R7M=P2?

Key risks include lower saturation current (Isat), which can cause performance issues at peak loads, and higher DC resistance (DCR), which can reduce power efficiency. Always check these against your design requirements.
