What risks should I check before replacing CMPI1040-100M?

The main risks are package mismatch and electrical parameter differences. Verify the substitute's footprint (LxWxH) and land pattern. Also, ensure its saturation current (Isat), RMS current (Irms), and DCR meet or exceed your design requirements.
