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

Yes, nSMD100-24V is a pin-compatible upgrade. JK-nSMD100-16 from Jinrui is also a strong pin-compatible candidate from another vendor, matching all key electrical parameters.

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

Before replacing, verify the hold (Ih) and trip (It) currents. A higher Ih may not protect the circuit as intended. Also check secondary parameters like post-trip resistance (R1max), as differences can affect circuit recovery time.
