Is there a pin-compatible replacement for HoLR2512-20mR-1%?

Yes, TAI-TECH RLP25FEGR020 and Milliohm LR2512D-3W-20mR-1% are considered pin-compatible replacements as they share the same 2512 package and key electrical parameters. However, it is always recommended to verify the datasheet land pattern.

What risks should I check before replacing HoLR2512-20mR-1%?

The main risk is selecting a substitute with a worse Temperature Coefficient (TCR), like ±100ppm/°C instead of ±50ppm/°C, which could reduce measurement accuracy. Also, verify the physical land pattern from the datasheet to ensure perfect mechanical fit.
