Package riskhigh
Most alternatives have different footprints requiring PCB changes.
Electrical riskmedium
The closest form-fit option has higher DCR, impacting efficiency.
Can it be replaced directly?
No direct drop-in replacement is available. The closest candidate, PSPMAA0605H-101M-IGF, has a similar footprint but different electrical characteristics (higher DCR).
Best replacement path
For minimal board changes, evaluate PSPMAA0605H-101M-IGF, accepting its higher DCR. For new designs, use a functional alternate with better electricals like PSPMAC1045H-101M-ANP.
Main risk
The main risk is physical incompatibility. Most electrically superior alternatives have larger footprints, requiring a board redesign.
