AI replacement insight

Application riskhigh

Using a non-AEC-Q200 part in an automotive design is a high risk.

Electrical risklow

Resistance values are close for the best candidates.

Package risklow

0603 is a standard, widely available package.

Can it be replaced directly?

Direct replacement for AC0603FR-072K4L should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The most reliable replacement path is to use another AEC-Q200 qualified resistor from Yageo's AC series, such as AC0603FR-072K49L.

Main risk

The main risk is substituting a general-purpose resistor (like the RC series) for the automotive-grade AC series, which could fail in harsh environments.

Recommended alternatives

A strong pin-compatible alternative with a very close resistance value (2.49kΩ) and matching AEC-Q200 qualification.
