What risks should I check before replacing RC0402FR-0780K6L?

The main risk is resistance mismatch. Several alternatives have resistance values like 82kΩ, a ~1.7% deviation from the target's 80.6kΩ. Verify if your circuit can tolerate this change. Also confirm secondary parameters like Temperature Coefficient (TCR) from the datasheet.

RC0402FR-0780K6L is a general-purpose 80.6kΩ, 1% tolerance, 1/16W thick film resistor in a 0402 package. A pin-compatible option and several parametric alternatives with slightly different resistance values are available.

AI replacement insight

Package risklow

All suggested alternatives use the same 0402 package.

Electrical riskmedium

Risk is medium for parametric parts due to resistance mismatch. Low for the pin-compatible option.

Can it be replaced directly?

Direct replacement for RC0402FR-0780K6L should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

For a direct replacement, use UNI-ROYAL 0402WGF8062TCE after review. If a small resistance change is acceptable, use Yageo RC0402FR-0782KL.

Main risk

The primary risk is resistance deviation when using parametric alternatives, which could affect circuit performance.

Recommended alternatives

A potential pin-compatible replacement from UNI-ROYAL with matching resistance, tolerance, power, and package.
