Is there a pin-compatible replacement for FPA252012D-3R3MT0?

TDK's TFM252012ALMA3R3MTAA and Murata's DFE252012F-3R3M=P2 share the same 2520 package and 2-pin configuration, making them likely pin-compatible. However, it is critical to verify the land pattern in the datasheet before assuming a direct drop-in replacement.

What risks should I check before replacing FPA252012D-3R3MT0?

The most critical risks are lower current ratings (both saturation current Isat and temperature current Itemp) and higher DC Resistance (DCR). A part with lower current handling can fail under load, while higher DCR reduces efficiency. Always verify these against your design requirements.
