Is there a pin-compatible replacement for FRC0603F2873TS?

Yes, parts in a standard 0603 package like AC0603FR-07300KL are pin-compatible. However, being pin-compatible does not guarantee it is a drop-in replacement; you must verify electrical parameters like power rating and resistance tolerance for your application.

What risks should I check before replacing FRC0603F2873TS?

The main risk is the power rating. The suggested alternatives have the same 0.1W rating as the target, offering no additional safety margin. You must confirm your circuit's actual power dissipation is well below 0.1W. Also, verify that the small difference in resistance is acceptable for your design.

Finding a substitute for the FRC0603F2873TS, a 287kΩ 1% 0.1W 0603 resistor, involves balancing resistance accuracy and power rating. Several pin-compatible alternatives exist, but require careful review of circuit power dissipation.

AI replacement insight

Electrical riskmedium

Candidates have no power rating margin over the target. Resistance values differ slightly.

Package risklow

All candidates share the same standard 0603 package.

Sourcing risklow

Alternatives from major manufacturers like Yageo are available.

Can it be replaced directly?

There are no drop-in replacements with an improved power rating among the candidates. Parts like AC0603FR-07300KL are pin-compatible and have very similar parameters but do not offer an increased power safety margin.

Best replacement path

Use an alternative with a close resistance value like AC0603FR-07300KL (AEC-Q200) or FRC0603F2943TS, but you must verify your circuit's power dissipation is safely below 0.1W.

Main risk

The primary risk is the lack of power rating margin. All viable alternatives have the same 0.1W rating as the target, which may be insufficient if the original design relied on manufacturer-specific derating curves.

Recommended alternatives

AEC-Q200 qualified resistor with 300kΩ resistance in the same 0603 package. Power rating must be verified.
