Is there a pin-compatible replacement for SWPA3015S2R2MT?

SWPA3015S2R2NT is a form-fit compatible candidate in the same 3015 package. However, its inductance tolerance is wider at ±30% compared to the original's ±20%, which requires engineering review.

What risks should I check before replacing SWPA3015S2R2MT?

First, check package compatibility; many alternatives have different footprints. Second, verify key electrical parameters like inductance tolerance, DC resistance (DCR), and current ratings (Irms, Isat) to ensure they meet your circuit's requirements.

AI replacement insight

Package riskhigh

Most alternatives are in different packages, requiring PCB redesign.

Electrical riskmedium

Form-fit options may have weaker tolerance; functional alternates have different DCR or current ratings.

Firmware risklow

Not applicable for a passive component.

Can it be replaced directly?

No direct drop-in replacement with identical specs has been identified. SWPA3015S2R2NT is in the same package but has a wider tolerance (±30% vs ±20%) which must be verified for the application.

Best replacement path

The best path is SWPA3015S2R2NT, which shares the same package but has a wider tolerance (±30%). For higher performance, consider SWPA4030S2R2MT, but this requires a PCB layout change.

Main risk

The main risk is package incompatibility. Most alternatives have different footprints, requiring PCB redesign. For same-package options, tolerance may be weaker.

Recommended alternatives

A form-fit candidate in the same 3015 package with similar ratings but a wider inductance tolerance.
