Is there a pin-compatible replacement for DFE252012PD-4R7M=P2?

Yes, parts like DFE252012P-4R7M=P2 and DFE252010F-4R7M=P2 use the same 2520 (1008) package and 2-pin layout, making them physically pin-compatible. However, you must verify electrical and qualification differences.

What risks should I check before replacing DFE252012PD-4R7M=P2?

The main risk is substituting a commercial-grade part into an automotive application that requires AEC-Q200 qualification. Also, check for parametric differences like higher DC resistance (DCR), which impacts efficiency, and lower current ratings, which can cause failure.
