TAI-TECH
A 3W upgrade from the same manufacturer, matching all other key electrical parameters and package.
Find reliable substitutes for the TAI-TECH RLP25FEER005, a 2W 5mΩ current sense resistor. Our analysis identifies several pin-compatible upgrades with higher power ratings for improved reliability.
Most candidates offer higher power ratings. One has a worse TCR, which requires review.
All recommended candidates use the same 2512 surface-mount package.
Multiple vendors offer suitable alternatives, improving supply chain resilience.
Direct replacement for RLP25FEER005 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The best replacement is RLP25FEGR005, an upgrade from the same manufacturer with a higher 3W power rating and identical key specs.
The primary risk is ensuring the substitute's Temperature Coefficient of Resistance (TCR) meets or exceeds the original's ±50ppm/℃ for precision applications.
