Is there a pin-compatible replacement for SWPA5020S220MT?

No direct pin-to-pin replacement has been verified. Candidates like NR5040S220MT share the same 5.0x5.0mm footprint but are taller, requiring a mechanical fit check before use.

What risks should I check before replacing SWPA5020S220MT?

Key risks include package mismatch (especially height), land pattern incompatibility, and changes in DC Resistance (DCR) which can affect circuit efficiency and thermals. Always verify the datasheet.

SWPA5020S220MT Alternatives, Datasheet & Cross Reference | Shenzhen Sunlord Electronics Co., Ltd.

Finding a substitute for the Sunlord SWPA5020S220MT 22µH inductor requires matching its 5.0x5.0x2.0mm package and electrical specs. Alternatives often have different heights, requiring careful review.

AI replacement insight

Electrical risklow

Most alternatives offer superior current and DCR ratings.

Package riskhigh

No identified substitute matches the target's 2.0mm height.

Can it be replaced directly?

No direct, drop-in replacement has been identified. All potential substitutes require a design review, primarily for mechanical fit.

Best replacement path

Upgrade to an inductor with the same footprint but higher current ratings, like the Magnetsyc NR5040 series, but you must verify the increased height is acceptable in your design.

Main risk

The primary risk is mechanical incompatibility due to different package heights, even when the footprint (land pattern) is similar.

Recommended alternatives

A strong electrical upgrade with a matching footprint but over double the height of the target.
