AI replacement insight

Electrical riskmedium

Some alternatives have different resistance values or unknown TCR.

Package risklow

All reviewed candidates share the same 0402 package.

Sourcing risklow

Multiple vendors offer similar 40.2Ω 0402 resistors.

Can it be replaced directly?

Direct replacement for FRC0402F40R2TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The most direct path is selecting a part with identical resistance, tolerance, power, and package, such as RC-02K40R2FT.

Main risk

The main risk is using a substitute with a different resistance value, which can alter circuit behavior. A secondary risk is an unverified Temperature Coefficient (TCR).

Recommended alternatives

Strong alternative with matching resistance, tolerance, power, TCR, and 0402 package.
