Is there a pin-compatible replacement for SWPA6045S101MT?

Currently, no pin-compatible replacement has been verified. All identified functional alternatives have different package dimensions and require board layout review.

What risks should I check before replacing SWPA6045S101MT?

Verify the substitute's PCB footprint, as no alternatives match the 6.0x6.0mm package. Also check if the circuit is sensitive to minor changes in DCR or saturation current characteristics.

Finding a substitute for the Sunlord SWPA6045S101MT 100µH inductor involves balancing electrical upgrades with physical package constraints. While several parts offer superior current handling, none are a direct drop-in replacement.

AI replacement insight

Package riskhigh

No candidates match the 6.0x6.0mm footprint, requiring board redesign.

Electrical risklow

Most alternatives offer superior current handling and lower DCR.

Sourcing riskmedium

Alternatives are from different manufacturers, which may have different supply chain characteristics.

Can it be replaced directly?

No direct pin-compatible replacement has been identified. All potential alternatives require package and layout verification.

Best replacement path

Use PSPMAA0805-101M-ANP for a significant electrical upgrade if board space allows for its larger 8.0x8.5mm footprint.

Main risk

The primary risk is package mismatch. No candidates share the target's 6.0x6.0mm footprint, requiring PCB layout changes.

Recommended alternatives

A strong electrical upgrade with much higher current and lower DCR, but in a larger package.
