Is there a pin-compatible replacement for SMMS1360-4R7M?

No pin-to-pin compatible replacement has been identified. While some parts share the 1360 package, their electrical characteristics like inductance and current ratings differ significantly, making them unsuitable as direct substitutes.

What risks should I check before replacing SMMS1360-4R7M?

Key risks include: 1) Package mismatch, requiring PCB redesign. 2) Inductance deviation, affecting converter frequency, ripple, and stability. 3) Lower current ratings (Isat/Irms), causing saturation or overheating. 4) Higher DCR, reducing efficiency.
