FRC0402F4221TS is a 4.22kΩ, 1% tolerance, 1/16W thick film resistor in a standard 0402 package. Alternatives exist from Yageo and others, with some offering direct parametric matches and others requiring evaluation due to different resistance values.

AI replacement insight

Electrical riskmedium

Using a part with a different resistance value requires circuit analysis to ensure performance is not compromised.

Package risklow

All suggested alternatives use the same standard 0402 package, minimizing physical compatibility issues.

Can it be replaced directly?

Direct replacement for FRC0402F4221TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The best direct replacement is RC0402FR-074K22L from Yageo, which matches all key electrical and physical parameters.

Main risk

The main risk when substituting is using a part with a different resistance value, which can alter circuit behavior. Always verify the resistance tolerance of your application.
