Upgrade path with superior current handling and efficiency, but in a much larger package.
Best Alternatives to SLS6D28S220MTT
Finding a replacement for the SLS6D28S220MTT 22µH inductor requires careful consideration of both electrical and mechanical parameters. While no direct drop-in replacements exist, several functional alternatives and upgrade paths are available that may require PCB layout adjustments.
AI replacement insight
Package riskhigh
No candidates match the 7.0x7.0mm footprint; PCB redesign is required.
Electrical riskmedium
Target's saturation current is unknown. Some candidates have higher DCR, increasing power loss.
Can it be replaced directly?
No direct pin-to-pin replacement was found for SLS6D28S220MTT. All suitable alternatives have different package dimensions and require board layout modifications.
Best replacement path
For an electrical upgrade, PSPMAA1040H-220M-ANP offers superior current handling but requires a larger footprint. For a closer size match, VLS6045EX-220M is a good upgrade but still needs layout verification.
Main risk
The primary risk is mechanical incompatibility due to different package sizes. A secondary risk is the unknown saturation current of the original part, which could lead to circuit failure if a replacement has a lower Isat.
