Is there a pin-compatible replacement for CRCW06034K87FKEA?

Yageo RT0603BRD074K87L is pin-compatible in terms of package (0603) and has the same 4.87kΩ resistance. However, it is not a guaranteed drop-in replacement because it lacks the target's AEC-Q200 automotive qualification.

What risks should I check before replacing CRCW06034K87FKEA?

The main risks are application and electrical mismatch. First, verify if your design requires an AEC-Q200 qualified resistor, as none of the suggested alternatives have it. Second, if considering 4.7kΩ parts, confirm your circuit can tolerate a -3.5% change in resistance.

AI replacement insight

Application riskhigh

All candidates lack the target's AEC-Q200 qualification.

Electrical riskmedium

Several candidates have a -3.5% resistance deviation that must be validated.

Package risklow

All candidates match the 0603 package, ensuring physical compatibility.

Can it be replaced directly?

No, there is no direct drop-in replacement for CRCW06034K87FKEA among the candidates reviewed, primarily due to the lack of AEC-Q200 qualification. Yageo RT0603BRD074K87L is a strong functional alternative for non-automotive designs.

Best replacement path

For non-automotive applications, Yageo RT0603BRD074K87L is the best choice, offering an exact resistance match with upgraded precision. For automotive use, no direct replacement was found; a different AEC-Q200 part is needed.

Main risk

The primary risk is the application mismatch; using a non-AEC-Q200 component in an automotive design that requires it can lead to reliability issues or failure to meet standards.

Recommended alternatives

A high-precision alternative with the same resistance but better tolerance and TCR; not AEC-Q200 qualified.
