Upgrade path to a 3W power rating, but requires board redesign for the larger 2512 package.
Best Alternatives to RLM20FECR050
TAI-TECH's RLM20FECR050 is a 1W, 50mΩ current sense resistor in a 2010 package. While no direct pin-compatible replacements are identified, several functional alternatives with higher power ratings in a larger 2512 package are available, requiring a PCB layout change.
AI replacement insight
Package riskhigh
No pin-compatible package found; requires board redesign.
Electrical risklow
Candidates offer matched or improved electrical specs (power, TCR).
Can it be replaced directly?
No direct, pin-for-pin replacement for RLM20FECR050 was found. All viable alternatives require a change in the PCB footprint.
Best replacement path
Upgrade to a higher-power 2512-package resistor like RLP25FEER050 if a PCB redesign is feasible.
Main risk
The primary risk is the package mismatch; the target is a 2010 package, while all suitable alternatives are in a larger 2512 size, mandating a board layout change.
