Is there a pin-compatible replacement for SWPA6028S220MT?

NR6028T220M from TAIYO YUDEN shares the same 6028 package and is considered pin-compatible from a layout perspective. However, it is not a direct drop-in due to a lower saturation current and narrower temperature range, requiring circuit validation.

What risks should I check before replacing SWPA6028S220MT?

Key risks include: 1) Package mismatch, as many alternatives have different footprints or heights. 2) Lower saturation current (Isat), which can cause the inductor to fail under peak load. 3) A narrower operating temperature range.

SWPA6028S220MT Alternatives, Datasheet & Cross Reference | Shenzhen Sunlord Electronics Co., Ltd.

Finding a replacement for the Sunlord SWPA6028S220MT, a 22µH power inductor, requires careful attention to both mechanical and electrical parameters. While several parts offer similar inductance, key differences in package size, saturation current, and temperature range must be reviewed.

AI replacement insight

Package riskhigh

Most alternatives have different footprints or are too tall for a drop-in replacement.

Electrical riskmedium

Closest package match has lower saturation current and a narrower temperature range.

Can it be replaced directly?

No direct drop-in replacement has been identified. The closest form-factor match, NR6028T220M, has a lower saturation current and requires engineering validation.

Best replacement path

NR6028T220M offers the same footprint but requires careful review of its lower saturation current and temperature range. Other options are electrically stronger but have incompatible packages.

Main risk

The primary risks are package incompatibility (height/footprint) and electrical derating, specifically lower saturation current, which can cause circuit failure.

Recommended alternatives

Same footprint but requires review due to lower saturation current and narrower temperature range.
