Is there a pin-compatible replacement for AC0402JR-074K7L?

Yes, several parts share the 0402 package. Yageo's AT0402BRD074K7L is a strong candidate that matches the package and automotive qualification. RALEC's RTT02472JTH matches the package and basic specs but lacks automotive qualification.

What risks should I check before replacing AC0402JR-074K7L?

First, ensure the replacement is AEC-Q200 qualified if for an automotive application. Second, if switching from thick film to thin film (e.g., with AT0402BRD074K7L), verify pulse handling capability meets your design's requirements.

AI replacement insight

Application riskhigh

Using a non-AEC part in an automotive design is a critical failure.

Electrical risklow

Key parameters match or are upgraded, but technology change from thick to thin film needs review.

Package risklow

Package is a standard 0402, ensuring physical compatibility.

Can it be replaced directly?

No exact direct replacement was found. The closest is Yageo's AT0402BRD074K7L, an automotive-grade upgrade. For non-automotive use, RALEC's RTT02472JTH is a functional match.

Best replacement path

The Yageo AT0402BRD074K7L is the best replacement, offering AEC-Q200 qualification and tighter tolerance, though it uses thin film technology.

Main risk

The main risk is using a non-AEC-Q200 part in an automotive application. A secondary consideration is the technology change from thick to thin film.

Recommended alternatives

AEC-Q200 qualified upgrade with tighter tolerance; technology changes from thick to thin film.
