Milliohm
This Milliohm resistor is an upgrade with a higher 3W power rating in the same 2512 package.
SMF25M2FR020T is a 2W, 20mΩ, 1% tolerance current sense resistor in a 2512 package. Several pin-compatible and upgrade alternatives with higher power ratings are available from various manufacturers.
Low if matching key specs. Medium if using a part with a worse TCR.
All suggested candidates are in the same 2512 package.
Multiple alternatives exist from different vendors.
Direct replacement for SMF25M2FR020T should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
For a direct replacement, consider RLP25FEER020 or MFL12HR020FT. For an upgrade, RLP25FEGR020 offers a higher 3W power rating.
The main risk is selecting a replacement with a worse Temperature Coefficient (TCR), which could affect circuit precision over temperature.
