Is there a pin-compatible replacement for SWPA6045S120MT?

No direct pin-compatible replacement with identical key parameters has been identified. CR6045H-100M shares the same package but has a lower inductance of 10µH, which requires engineering validation.

What risks should I check before replacing SWPA6045S120MT?

Key risks include inductance mismatch, which can affect power converter performance, and package differences, which require a board redesign. Always verify current ratings (Irms, Isat) and DC Resistance (DCR).

AI replacement insight

Electrical riskmedium

Inductance values vary, which can affect power converter performance and tuning.

Package riskhigh

One strong electrical match has a different package, requiring a board redesign.

Can it be replaced directly?

No direct, drop-in replacement for SWPA6045S120MT has been confirmed. All candidates require engineering review.

Best replacement path

For new designs, PSPHAQ127-120M offers superior electrical performance. For existing boards, CR6045H-100M is an option if the circuit tolerates 10µH inductance.

Main risk

The primary risk is finding a part with both matching 12µH inductance and the 6045 package. Candidates either differ in inductance or package size.

Recommended alternatives

A potential alternative in the same package with higher current ratings, but lower inductance (10µH) must be verified.
