Is there a pin-compatible replacement for MLP2012S3R3MT0S1?

No direct pin-compatible replacement with equal or better current rating has been identified. MLZ2012M3R3ATD69 shares the same 2012 (0805) package but has a much lower current rating (350mA vs 900mA) and requires careful review.

What risks should I check before replacing MLP2012S3R3MT0S1?

The primary risk is current handling; many same-size inductors have lower ratings. Also check DC Resistance (DCR) for efficiency impacts, and ensure any alternative's package matches your PCB layout.
