AI replacement insight
Package riskhigh
All candidates have different footprints, requiring PCB layout changes or verification.
Electrical riskmedium
Some candidates have lower saturation current, which could cause issues in high-peak-current applications.
Can it be replaced directly?
No direct pin-for-pin replacement has been identified. All candidates require package and/or electrical parameter verification.
Best replacement path
FEXL0660A-5R6M offers superior current ratings and lower DCR, but its smaller package requires layout verification.
Main risk
The primary risk is package mismatch. No candidates share the exact 7.3x6.6mm footprint of the target part.
