UNI-ROYAL
UNI-ROYAL 0603WAF1100T5E is a strong pin-to-pin candidate with identical key electrical parameters and package.
FRC0603F1100TS is a general-purpose 110Ω 1% 0.1W resistor in a 0603 package. Several pin-compatible and parametric alternatives are available from manufacturers like UNI-ROYAL, Yageo, and Vishay.
Using a resistor with a different value (e.g., 100Ω or 120Ω) will change currents and voltages. Must be verified.
All suggested candidates use the standard 0603 package, ensuring physical compatibility.
Direct replacement for FRC0603F1100TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Start with Datasheet verified or Strong match candidates for FRC0603F1100TS, then review parametric alternatives for package and electrical fit.
The main risk is substituting with a part that has a different resistance value, which can alter circuit behavior.
