AF0402FR-071KL
Yageo
Needs validationmedium risk
An automotive, anti-sulfurated resistor that matches features but has lower power and voltage ratings.
Best Alternatives to AC0402FR-7W1KL
Finding a substitute for the Yageo AC0402FR-7W1KL requires careful attention to its key features: a high power rating (1/8W) for its 0402 size and AEC-Q200 automotive qualification. Many alternatives match the resistance and package but fall short on these critical electrical and reliability specifications.
AI replacement insight
Electrical riskhigh
Most alternatives have lower power and voltage ratings.
Package risklow
All candidates match the 0402 package.
Sourcing riskhigh
Replacing an automotive-grade part with a commercial one introduces reliability and compliance risks.
Can it be replaced directly?
No direct, drop-in replacement with identical or better ratings was found. All reviewed candidates require compromises on power, voltage, or automotive qualification.
Best replacement path
The best path is to use another AEC-Q200 qualified resistor, but this will likely require accepting a lower power or voltage rating. Yageo's AF0402FR-071KL is functionally closest but requires derating analysis.
Main risk
The primary risk is using a substitute with a lower power (1/16W vs 1/8W) or voltage (50V vs 75V) rating, which could lead to component failure in demanding automotive applications.
