Is there a pin-compatible replacement for SWPA6045S470MT?

No. None of the reviewed candidates are pin-compatible with the SWPA6045S470MT. All proposed alternatives use a larger package (approximately 7x7mm vs. the target's 6x6mm), which requires a different PCB footprint.

What risks should I check before replacing SWPA6045S470MT?

Before replacing, you must verify two key risks. First, check the mechanical fit; all alternatives are larger and require a different PCB layout. Second, evaluate the electrical impact of higher DC Resistance (DCR), which will increase power loss and component temperature.

SWPA6045S470MT Alternatives, Datasheet & Cross Reference | Shenzhen Sunlord Electronics Co., Ltd.

Finding a replacement for the Sunlord SWPA6045S470MT 47µH inductor requires balancing trade-offs. While functional alternatives exist, they differ in package size and DC resistance, necessitating careful review.

AI replacement insight

Package riskhigh

No candidates match the 6045 package; all viable options are larger.

Electrical riskmedium

Alternatives have ~2x higher DCR, impacting efficiency and thermal performance.

Can it be replaced directly?

No direct drop-in replacement was found among the candidates. All viable options require engineering review for package fit and electrical performance trade-offs, specifically higher power loss.

Best replacement path

Consider functional alternatives like SLO0650H470MTT if the PCB can be modified for a ~7x7mm footprint and the application can tolerate double the DC resistance.

Main risk

The primary risks are package incompatibility, requiring a PCB layout change, and increased power loss and heat due to higher DC Resistance (DCR) in all functional alternatives.

Recommended alternatives

Functional alternative with higher current ratings, but a larger package and higher DCR.
