Is there a pin-compatible replacement for TMPA1265SP-100MN-D?

No direct pin-to-pin replacement has been verified. CYA1265-10UH has a similar package size that may be compatible, but its electrical performance is a downgrade and requires careful review of the land pattern and thermal performance.

What risks should I check before replacing TMPA1265SP-100MN-D?

Key risks include package size mismatch requiring PCB redesign, lower rated current (Irms) causing overheating, and higher DCR leading to increased power loss. Always verify the candidate's datasheet against your application's requirements.
