Is there a pin-compatible replacement for MPL2520S100MWT?

Yes, several inductors like VLS252012HBX-100M-1 use the same 2520 package and pinout. However, electrical parameters like DCR, current rating, and height differ, so they are not drop-in replacements without engineering review.

What risks should I check before replacing MPL2520S100MWT?

Key risks include: 1) Lower current rating (Isat/Irms) causing saturation or overheating. 2) Higher DC Resistance (DCR) reducing power efficiency. 3) Different physical height impacting mechanical clearance.

MPL2520S100MWT Alternatives, Datasheet & Cross Reference | Shenzhen Sunlord Electronics Co., Ltd.

Finding a substitute for the Sunlord MPL2520S100MWT 10µH inductor involves matching its 2520 package, 0.8A current rating, and 0.3Ω DCR. Alternatives exist with varying performance trade-offs in current handling and efficiency.

AI replacement insight

Electrical riskmedium

Candidates have different DCR and current ratings that must be validated for the application.

Package risklow

Form-fit candidates exist, but height can vary slightly, requiring mechanical check.

Sourcing risklow

Multiple vendors manufacture inductors in this common package and value.

Can it be replaced directly?

No perfect drop-in replacement was found. VLS252012HBX-100M-1 is the closest match but has higher DCR and is 0.1mm taller. All candidates require careful review of electrical and mechanical differences.

Best replacement path

VLS252012HBX-100M-1 offers higher current ratings but at the cost of higher DCR and a slightly taller package, making it a strong functional alternative if efficiency and height are not critical.

Main risk

The primary risk is finding a part with an equivalent or better combination of current rating and low DCR in the same 2520 package. Many alternatives compromise on one of these key parameters.

Recommended alternatives

A form-fit option with better DCR but a lower current rating, posing a downgrade risk.
