What risks should I check before replacing FRC1206F2R40TS?

Key risks include mismatched resistance tolerance (e.g., 5% vs 1%), different resistance values, or a worse temperature coefficient (TCR). Ensure the substitute's power rating is equal or greater.

FRC1206F2R40TS Alternatives, Datasheet & Cross Reference | FOJAN

FRC1206F2R40TS is a 2.4Ω, 1% tolerance, 0.25W thick film chip resistor in a standard 1206 package. When searching for replacements, focus on matching these key parameters and the package size.

AI replacement insight

Electrical risklow

Low if key parameters match. Medium if tolerance or resistance is relaxed.

Package risklow

1206 is a standard SMT package, ensuring mechanical compatibility.

Can it be replaced directly?

Direct replacement for FRC1206F2R40TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Prioritize candidates with identical resistance, tolerance, power, and 1206 package. Yageo's RC1206FR-072R4L is a top choice.

Main risk

The main risk is using a substitute with a wider resistance tolerance (e.g., 5% instead of 1%), which can impact circuit performance.

Recommended alternatives

Yageo RC1206FR-072R4L is a strong pin-compatible alternative with an improved temperature coefficient.
