Is there a pin-compatible replacement for JK-nSMD100-16?

Yes, the TECHFUSE nSMD100-16V is a pin-compatible replacement. It matches the 1206 package, 1.0A hold current, 1.8A trip current, and 16V maximum voltage.

What risks should I check before replacing JK-nSMD100-16?

Ensure the replacement has the same or higher voltage rating (16V) and a hold current very close to 1.0A. Using a part with a higher hold current can compromise circuit protection. Also verify secondary parameters like trip time and post-trip resistance if your application is sensitive to them.
