Is there a pin-compatible replacement for AC0603FR-0768KL?

Yes, parts like Yageo RC0603FR-0768K1L are pin-compatible in the 0603 package. However, it is not a drop-in replacement as it lacks the target's AEC-Q200 automotive qualification, which requires engineering review.

What risks should I check before replacing AC0603FR-0768KL?

First, verify if your application requires AEC-Q200 qualification. Using a non-qualified part poses a reliability risk. Second, check for any parametric differences like resistance value and tolerance to ensure they are acceptable for your circuit.

Electrical riskhigh

Candidates may have different resistance or tolerance.

Package risklow

All reviewed candidates share the same 0603 package.

Can it be replaced directly?

No direct, fully-qualified drop-in replacement has been identified. All candidates require review, especially for the missing AEC-Q200 automotive qualification.

Best replacement path

Search for other AEC-Q200 qualified 0603 resistors with 68kΩ resistance, ±1% tolerance, and ≥1/10W power rating.

Main risk

The primary risk is using a non-automotive grade component in an application requiring AEC-Q200 reliability standards.

Recommended alternatives

A general-purpose resistor with similar core parameters but lacks the target's automotive qualification.
