Is there a pin-compatible replacement for SWPA6045S4R7MT?

No pin-compatible replacements have been verified at this time. Available alternatives like SMMS0630-4R7M have different package dimensions (7.1x6.6mm vs 6.0x6.0mm) and are not drop-in replacements.

What risks should I check before replacing SWPA6045S4R7MT?

The primary risk is mechanical incompatibility; all reviewed alternatives have a larger footprint requiring a board redesign. Also, check DCR, as a higher value can reduce efficiency, and ensure saturation current meets peak current needs.

SWPA6045S4R7MT is a 4.7µH shielded power inductor in a 6.0x6.0mm package. While no direct pin-compatible replacements are confirmed, several functional alternatives with similar or better electrical performance are available in slightly larger packages, requiring PCB layout a...

AI replacement insight

Package riskhigh

All viable alternatives have a larger footprint, requiring a board redesign.

Electrical risklow

Candidates offer similar or superior current ratings and matching inductance.

Can it be replaced directly?

No direct, pin-compatible replacement has been identified. All viable alternatives require a change in the PCB layout due to different package sizes.

Best replacement path

Functional upgrade to SLO0630H4R7MTT for better performance, if a PCB redesign is feasible.

Main risk

Package mismatch is the main risk, as no alternatives share the target's 6045 (6.0x6.0mm) footprint.

Recommended alternatives

Functional alternative with higher current ratings but different package and slightly higher DCR.
