Is there a pin-compatible replacement for SMMS1350-100M?

No direct pin-for-pin replacement has been verified. Alternatives have similar footprints but may differ in height, requiring a layout and clearance check before use.

What risks should I check before replacing SMMS1350-100M?

Check three things: 1) The inductance must be 10uH. 2) Saturation and RMS currents must be equal to or greater than 12A and 8A, respectively. 3) The physical package, especially the height, must fit on your PCB.

SMMS1350-100M Alternatives, Datasheet & Cross Reference | SXN

SMMS1350-100M is a 10uH shielded power inductor from SXN in a 1350 package, rated for 12A saturation current. Finding a replacement requires matching inductance and ensuring current ratings and package dimensions are compatible.

Package riskmedium

Alternatives have similar footprints but may be taller, requiring clearance checks.

Electrical risklow

Proposed alternatives offer superior current ratings and lower DCR.

Can it be replaced directly?

No verified pin-to-pin replacements are available. Several functional alternatives exist with superior current ratings but may be taller, requiring mechanical verification.

Best replacement path

Use a functional alternative with 10uH inductance and equal or better current ratings. Pay close attention to package height.

Main risk

The primary risk is mechanical incompatibility, specifically the component height. Some alternatives are 1mm taller.

Recommended alternatives

A functional alternative with significantly higher saturation current (21A vs 12A) and lower DCR, but is 1mm taller.
