AI replacement insight
Electrical risklow
TCR is unverified and critical for some applications.
Package risklow
Candidates use the same 1812 package.
Can it be replaced directly?
Direct replacement for FRC1812J102 TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Upgrade to a 1% tolerance part like 181207F1001T4E for better precision, after verifying its TCR.
Main risk
The primary risk is an unverified Temperature Coefficient of Resistance (TCR), which could affect circuit stability over temperature.
