Is there a pin-compatible replacement for AC0402FR-0775KL?

No pin-compatible replacement that matches all specifications, including the critical AEC-Q200 qualification and ±1% tolerance, has been identified. All suggested alternatives have parametric differences that require engineering review.

What risks should I check before replacing AC0402FR-0775KL?

The main risks are application and electrical. First, ensure any replacement is AEC-Q200 qualified if your design is automotive. Second, verify that your circuit can function correctly with any change in resistance tolerance (e.g., from ±1% to ±5%) or technology (Thick vs. Thin Film).

AC0402FR-0775KL Alternatives, Datasheet & Cross Reference | Yageo

AI replacement insight

Electrical riskhigh

Switching to a ±5% tolerance part may affect circuit performance.

Application riskhigh

Using a non-AEC-Q200 part in an automotive design can violate system requirements.

Package risklow

All viable candidates match the 0402 package.

Can it be replaced directly?

There is no direct, drop-in replacement identified that matches all key parameters including AEC-Q200 qualification and ±1% tolerance. All candidates require engineering review.

Best replacement path

For applications that can tolerate a wider resistance range, AC0402JR-0775KL is the best path as it maintains the AEC-Q200 qualification. For non-automotive designs needing higher precision, RT0402BRD0775KL is a strong upgrade.

Main risk

The primary risk is substituting a non-AEC-Q200 qualified part into an automotive application, or using a part with a wider tolerance (±5%) where ±1% is required.

Recommended alternatives

AEC-Q200 qualified alternative from the same Yageo AC series with a wider ±5% tolerance.
