AI replacement insight
Electrical riskmedium
Most alternatives have different resistance values. The best match has an unverified TCR.
Package risklow
All candidates share the same 0402 package, ensuring form and fit compatibility.
Sourcing risklow
Multiple alternatives are available from large, reputable manufacturers like Yageo and UNI-ROYAL.
Can it be replaced directly?
Direct replacement for FRC0402F6491TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Use UNI-ROYAL 0402WGF6491TCE for a direct resistance match, but verify TCR and voltage margin. For more options, consider Yageo parts if a ~5% resistance change is acceptable.
Main risk
The main risk is substituting with a part that has a different resistance value, which could alter circuit performance. This requires engineering evaluation.
