Is there a pin-compatible replacement for JK-NSMD035-16?

Yes, several PTC fuses in a 1206 package are pin-compatible, including the BNSTAR SMD1206 series. However, a perfect electrical match for the 0.35A hold current must be carefully verified.

What risks should I check before replacing JK-NSMD035-16?

The most critical risk is a mismatch in hold and trip currents, which could compromise overcurrent protection. Also verify the time-to-trip and post-trip resistance characteristics from the datasheets.

JK-NSMD035-16 Alternatives, Datasheet & Cross Reference | Jinrui Electronic Materials Co.

Finding a replacement for the JK-NSMD035-16 PTC fuse requires matching hold current (0.35A), voltage (16V), and a 1206 package. Alternatives exist but may require parametric trade-offs on current ratings.

AI replacement insight

Electrical riskmedium

Higher hold/trip currents alter the circuit's protection characteristics.

Package risklow

Candidates share the same 1206 package, ensuring physical compatibility.

Can it be replaced directly?

No direct drop-in replacement was found. Alternatives like the BNSTAR SMD1206-050C series have the same package but a higher hold current, requiring careful review.

Main risk

The primary risk is using a substitute with a higher hold current, which could lead to circuit damage by failing to trip under expected fault conditions.

Recommended alternatives

A form-fit alternative with a higher voltage rating, but its higher hold current requires careful engineering review.
