AI replacement insight
Electrical riskmedium
Must verify key parameters like clamping voltage and leakage current.
Package risklow
0402 package is standard and widely available.
Can it be replaced directly?
No exact 1-to-1 direct replacement is listed, but the BORN 0402ESDA-24N is a near-identical part from the same family with a higher voltage rating, making it a very low-risk substitute.
Best replacement path
For a low-risk upgrade, use 0402ESDA-24N from the same manufacturer. For improved performance, especially in high-speed circuits, the Littelfuse AXGD10402KR is a superior choice.
Main risk
The primary risk is selecting a substitute with weaker protection characteristics, such as higher clamping voltage or leakage current, which could compromise circuit reliability.
