Is there a pin-compatible replacement for MLP2520S4R7MT0S1?

Several candidates like AFE252010S4R7MBT use the same 2520 package and are expected to be pin-compatible. However, no candidate is a guaranteed drop-in replacement without verifying electrical parameters for your circuit.

What risks should I check before replacing MLP2520S4R7MT0S1?

Key risks are: 1) Efficiency loss from higher DC Resistance (DCR). 2) Circuit failure if the candidate's saturation current (Isat) is too low. 3) Changes in EMI or AC performance due to different inductor technologies.
