AI replacement insight
Electrical riskmedium
Many candidates have a lower standoff voltage, requiring circuit validation.
Package risklow
All viable candidates use the same standard SOD882 package.
Can it be replaced directly?
No exact 1-to-1 replacement was found. The closest is SP3522-01ETG, an upgrade. Other candidates have a lower voltage rating and pose a downgrade risk.
Best replacement path
The best path is to use an upgrade like Littelfuse's SP3522-01ETG, which offers superior electrical characteristics in the same package.
Main risk
The primary risk is selecting a part with a reverse standoff voltage lower than the target's 5.5V, which could lead to premature clamping or device failure.
