UNI-ROYAL
Potential pin-to-pin match with identical R/P/Tol, but requires TCR verification from datasheet.
Find substitutes for the FRC0805F2103TS, a 210kΩ 1% 0.125W 0805 thick film resistor. Alternatives may require verifying resistance value and temperature coefficient.
All suggested alternatives use the same 0805 package.
Most alternatives have a different resistance value. The best match requires TCR verification.
Direct replacement for FRC0805F2103TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Direct replacement if TCR matches, otherwise parametric relaxation.
The primary risk is using a substitute with a different resistance value or temperature coefficient without circuit analysis.
