FH (Guangdong Fenghua Advanced Tech)
A strong pin-compatible match on all key electricals, but lacks the target's AEC-Q200 qualification.
Find and compare replacements for the TAI-TECH RLM12FTCMR010, a 1W, 10mΩ, 1% AEC-Q200 current sense resistor. Alternatives are available but require careful review of TCR and automotive qualification.
Several candidates have a weaker TCR, which can impact precision over temperature.
Most candidates share the same 1206 package, ensuring physical compatibility.
Using a non-AEC-Q200 part in an automotive design introduces significant qualification and reliability risk.
Direct replacement for RLM12FTCMR010 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
For a non-automotive application, MFJ06HR010FT is the best path as it matches all key electricals. For an AEC-Q200 application, FMF06FTHR010-LH is the best choice, but requires validating the impact of its slightly higher TCR.
The main risks are mismatched Temperature Coefficient of Resistance (TCR) affecting measurement accuracy, and lack of AEC-Q200 qualification for automotive use.
