Needs validationlow risk
Potential pin-compatible upgrade with higher saturation current (2.1A vs 1.23A) and lower DCR.
Best Alternatives to SMRH74-220MT
Finding a replacement for the SMRH74-220MT 22µH inductor involves matching its 7.5x7.5mm package and electrical ratings. Several alternatives exist with varying performance and package sizes.
AI replacement insight
Electrical risklow
Most candidates offer superior current ratings and lower DCR.
Package riskhigh
Most candidates require a PCB redesign. Pin-compatible option needs footprint verification.
Sourcing risklow
Multiple vendors offer inductors with similar specifications.
Can it be replaced directly?
Direct replacement for SMRH74-220MT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Start with Datasheet verified or Strong match candidates for SMRH74-220MT, then review parametric alternatives for package and electrical fit.
Main risk
The primary risk is package mismatch. Most alternatives have different footprints, requiring a PCB redesign. For the pin-compatible option, slight dimensional differences could still affect automated assembly.
