Is there a pin-compatible replacement for RC0603FR-0768K1L?

Yes, AC0603FR-0768KL is a pin-compatible replacement. It shares the same 0603 package, 1/10W power rating, and 1% tolerance, with a negligible 0.15% difference in resistance.

What risks should I check before replacing RC0603FR-0768K1L?

Before replacing, check three main risks: 1) Resistance Tolerance: Ensure the substitute's tolerance (e.g., ±1%) meets your circuit's needs. 2) Resistance Value: Verify any deviation from 68.1kΩ is acceptable. 3) Temperature Coefficient (TCR): For stable circuits, ensure the TCR is comparable or better.

RC0603FR-0768K1L Alternatives, Datasheet & Cross Reference | Yageo

AI replacement insight

Electrical risklow

Most candidates have similar electrical ratings. The key risk is deviating from the 1% resistance tolerance or the 68.1kΩ value.

Package risklow

All reviewed candidates use the same 0603 package, ensuring physical compatibility.

Sourcing risklow

Alternatives are available from multiple manufacturers (Yageo, FOJAN), mitigating single-source issues.

Can it be replaced directly?

Yes, Yageo's AC0603FR-0768KL is a direct pin-compatible replacement for RC0603FR-0768K1L, offering a negligible resistance difference and an upgrade to automotive grade.

Best replacement path

AC0603FR-0768KL is the best replacement. It's from the same manufacturer, has nearly identical specs, and adds AEC-Q200 qualification for higher reliability.

Main risk

The main risk when substituting is a mismatch in resistance tolerance. For applications requiring 1% precision, using a 5% tolerance part like FRC0603J683 TS could cause circuit failure.

Recommended alternatives

Excellent pin-compatible alternative from the same manufacturer with a negligible resistance difference and upgraded AEC-Q200 qualification.
