AI replacement insight
Application riskhigh
Using a non-automotive part in an AEC-Q101 required design is a major compliance and reliability risk.
Electrical risklow
Parametric differences are minor or beneficial for non-automotive use. Vf and IR should be verified.
Package risklow
Several candidates share the same SOD523 package, ensuring physical compatibility.
Can it be replaced directly?
Direct replacement for RB521S30,115 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
For non-automotive applications, 1PS79SB30,115 is the best alternative, offering higher voltage and lower forward voltage. For automotive, no direct replacement was found.
Main risk
The primary risk is using a non-AEC-Q101 qualified part in an automotive design that requires it, potentially leading to reliability issues or non-compliance.
