What risks should I check before replacing FRC0603F6801TS?

Key risks include package size mismatch, tolerance differences (e.g., 5% vs 1%), and technology changes (Thick vs. Thin Film). Ensure the replacement meets or exceeds the original's power and voltage ratings.

FRC0603F6801TS Alternatives, Datasheet & Cross Reference | FOJAN

Find and compare alternatives for the FOJAN FRC0603F6801TS, a 6.8kΩ 1% 0.1W 0603 thick film resistor. This guide provides pin-compatible matches, functional upgrades, and parametric alternatives.

AI replacement insight

Electrical risklow

Low if key parameters (R, Tol, P) match. Medium if tolerance is wider or technology differs.

Package riskhigh

High if a non-0603 package is chosen, as it requires a PCB redesign.

Sourcing risklow

This is a very common resistor value and package, with many available suppliers.

Can it be replaced directly?

Direct replacement for FRC0603F6801TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Direct pin-to-pin replacement with another thick film resistor like UNI-ROYAL 0603WAF6801T5E.

Main risk

The main risk is selecting a part with incorrect tolerance (e.g., 5%) or a different package size (e.g., 0805) without design verification.

Recommended alternatives

A strong pin-compatible alternative with identical resistance, tolerance, power rating, and 0603 package.
