Is there a pin-compatible replacement for TLC-NSMD100?

Yes, several parts like SMD1206P150TF are available in the same 2-pin 1206 package. While they are pin-compatible, their electrical characteristics, especially current ratings, differ and must be verified.

What risks should I check before replacing TLC-NSMD100?

The main risk is the higher hold and trip current ratings of all potential substitutes. This could lead to failure to protect the circuit in an overcurrent situation. Always verify the new trip point is safe for your design.

TLC-NSMD100 Alternatives, Datasheet & Cross Reference | TLC Electronic

Finding a substitute for the TLC-NSMD100, a 1A/6V 1206 PTC resettable fuse, requires careful review. While pin-compatible options exist, they often have different current ratings that impact circuit protection.

AI replacement insight

Electrical riskhigh

All candidates have higher hold/trip currents. This can prevent the fuse from tripping when it should, risking damage.

Package risklow

All viable candidates use the same 1206 package, ensuring physical compatibility on the PCB.

Can it be replaced directly?

No direct drop-in replacement was found. All candidates have different current ratings that require engineering review.

Best replacement path

Use a functional alternate like SMD1206P150TF, but verify the higher 1.5A hold current is acceptable for the application.

Main risk

The primary risk is electrical; using a substitute with a higher hold/trip current may leave the downstream circuit unprotected from overcurrent events.

Recommended alternatives

Functionally similar PTC fuse in a 1206 package with higher voltage and current ratings.
