Is there a pin-compatible replacement for SLT050125T470MUB?

No pin-compatible replacement has been verified. The target is a through-hole toroidal inductor, and the closest functional alternatives found are surface-mount (SMD) parts, which are not physically compatible without board redesign.

What risks should I check before replacing SLT050125T470MUB?

Key risks include: 1) Package Mismatch: Ensure your PCB can accommodate an SMD part instead of a through-hole one. 2) Higher DCR: Alternatives may have higher DC resistance, impacting circuit efficiency and heat. 3) Saturation Current: Verify the replacement's saturation current (Isat) is sufficient for your application's peak currents.

Package riskhigh

SMD vs. Through-Hole requires board redesign.

Electrical riskmedium

Alternatives have higher DCR, impacting efficiency. Target Isat is unknown.

Sourcing risklow

Functional alternatives from multiple vendors are available.

Can it be replaced directly?

No direct pin-compatible replacement has been identified. All reviewed candidates have a different package (SMD) and would require a new PCB layout.

Best replacement path

The best path is to find a through-hole toroidal inductor with 47µH inductance, DCR ≤ 38mΩ, and Irms ≥ 3.5A. The candidates found are SMD, requiring board redesign.

Main risk

The primary risk is the package mismatch, as all viable alternatives are Surface Mount Devices (SMD) while the target is a Through-Hole component.

Recommended alternatives

A functional alternative with matching inductance and higher current, but in a different (SMD) package.
