Is there a pin-compatible replacement for FNRH201610S-100MT?

WPN201610H100MT shares the same 2-pin 2.0x1.6mm package and is a likely form-fit replacement. A full pin-to-pin compatibility check requires datasheet and layout verification.

What risks should I check before replacing FNRH201610S-100MT?

The main risk is package incompatibility; many alternatives are larger and require a PCB redesign. Also, check saturation current (Isat) and DC resistance (DCR) to ensure they meet or exceed your circuit's requirements.

Finding a substitute for the FNRH201610S-100MT 10uH inductor involves balancing package size with electrical performance. While several functional alternatives offer higher current ratings, only a few match the compact 2016 footprint.

AI replacement insight

Package riskhigh

Most alternatives are not in a 2016 package, requiring a board redesign.

Electrical risklow

Most candidates offer superior current and DCR ratings.

Can it be replaced directly?

A direct, verified drop-in replacement is not guaranteed without board-level testing. WPN201610H100MT is the most promising candidate for a direct replacement.

Best replacement path

Prioritize WPN201610H100MT for a near drop-in upgrade. If unavailable, a board redesign is needed for larger, higher-performance parts like VLS3012CX-100M-1.

Main risk

Package mismatch is the primary risk, as most alternatives are physically larger and require a PCB redesign.

Recommended alternatives

Strong alternative in the same 2016 package with higher current ratings and lower DCR.
