Is there a pin-compatible replacement for CQ02WGF2552TCE?

No pin-compatible replacement has been confirmed. While parts like RC0402FR-0725K5L match the package and electricals, they are not automotive grade and are not considered direct replacements for the intended application.

What risks should I check before replacing CQ02WGF2552TCE?

The main risk is application mismatch. The target part is AEC-Q200 qualified for automotive use. Using a commercial-grade substitute in such an environment could lead to premature failure and violate system requirements.

AI replacement insight

Application riskhigh

Substituting a commercial part for an automotive-grade one can lead to failures under harsh conditions.

Package risklow

All strong candidates share the same 0402 package, ensuring physical compatibility.

Can it be replaced directly?

No direct, drop-in replacement has been identified. While several parts match key electrical parameters, they lack the target's AEC-Q200 automotive qualification.

Best replacement path

For non-automotive use, Yageo RC0402FR-0725K5L is a strong functional match. For automotive applications, a new search for AEC-Q200 qualified 25.5kΩ 0402 resistors is required.

Main risk

Using a commercial-grade component in an automotive application that requires AEC-Q200 qualified parts, potentially affecting system reliability and compliance.

Recommended alternatives

A commercial-grade resistor from FOJAN with matching specs but no automotive qualification.
