Is there a pin-compatible replacement for MWTC252010S2R2MT?

Yes, several inductors share the same 2520 package and 2.2µH inductance. XRIM252012S2R2MBCA is a strong candidate for a pin-compatible upgrade. Other parts are also pin-compatible but may have lower performance, so their datasheets must be reviewed.

What risks should I check before replacing MWTC252010S2R2MT?

Before replacing MWTC252010S2R2MT, you must verify the substitute's key electrical parameters. The most critical are the saturation current (Isat) and RMS current (Irms), which must be equal to or greater than the original's 3.5A and 2.6A, respectively. Also, check the DC Resistance (DCR), as a higher value will reduce circuit efficiency.
