Is there a pin-compatible replacement for RLP25FEER100?

Yes, parts like RLP25FEER200 are pin-compatible in the same 2512 package, but their electrical resistance is different, making them functional but not direct drop-in replacements.

What risks should I check before replacing RLP25FEER100?

The main risk is the resistance value. Verify the new resistance is compatible with your current sensing amplifier gain and that the change in voltage drop and power dissipation is acceptable for your design.

RLP25FEER100 Alternatives, Datasheet & Cross Reference | TAI-TECH
