Needs validationmedium risk
AEC-Q200 qualified upgrade with better clamping, but ultra-low capacitance requires design review.
Best Alternatives to 0402ESDA-24N
0402ESDA-24N is a 24V bi-directional polymer ESD suppressor in a 0402 package, notable for its ultra-low leakage current (<1nA) and 1.5pF capacitance. Finding a direct replacement requires careful matching of these key electrical parameters.
AI replacement insight
Electrical riskhigh
Leakage current and capacitance differences are significant across candidates.
Package risklow
The 0402 package is common and several candidates match the footprint.
Can it be replaced directly?
No direct drop-in replacement was found. All candidates have significant parametric differences in leakage current or capacitance, requiring engineering validation.
Best replacement path
For high-speed signals, upgrade to an ultra-low capacitance part like AXGD10402KR. For general use, SLESDL0402-24 is a closer capacitance match but is a downgrade on leakage.
Main risk
The main risk is circuit malfunction or performance degradation due to mismatched leakage current and capacitance.
