Is there a pin-compatible replacement for AC0402FR-0782KL?

Yes, several parts like RT0402BRD0782KL and RC0402FR-0782K5L share the same 0402 package and 2-pin layout. However, they are not functionally identical due to differences in automotive qualification and other parameters.

What risks should I check before replacing AC0402FR-0782KL?

The primary risk is substituting a non-AEC-Q200 qualified part into an automotive application, which can affect reliability. Also, check for minor resistance differences and technology type (Thin vs. Thick Film).

AC0402FR-0782KL Alternatives, Datasheet & Cross Reference | Yageo

Finding a substitute for the Yageo AC0402FR-0782KL, an 82kΩ 1% 0402 resistor, requires careful attention to its AEC-Q200 automotive qualification. While pin-compatible options exist, they often lack this critical feature.

AI replacement insight

Electrical riskhigh

Using a non-AEC-Q200 part in an automotive design can lead to premature failure and reliability issues.

Package risklow

All viable candidates match the 0402 package, ensuring physical compatibility.

Sourcing riskhigh

Substituting with a non-qualified part may violate design or regulatory requirements for the end product.

Can it be replaced directly?

There is no direct, verified drop-in replacement for AC0402FR-0782KL among the candidates, primarily due to the lack of AEC-Q200 qualification.

Best replacement path

No direct automotive-grade replacement was found. For non-automotive applications, RT0402BRD0782KL offers higher precision. For general-purpose use, RC0402FR-0782K5L is a closer parametric match.

Main risk

The main risk is using a non-automotive grade component in an application that requires the reliability and testing standards of AEC-Q200.

Recommended alternatives

A higher precision alternative, but not automotive grade and uses different film technology. Requires engineering review.
