Is there a pin-compatible replacement for TLC-NSMD005?

Several candidates like SMD1206-005C-60V share the same 1206 package and 2-pin layout, making them potential pin-compatible replacements. However, electrical parameters like resistance and trip time should be verified for your specific application.

What risks should I check before replacing TLC-NSMD005?

Key risks include differences in trip time, post-trip resistance, and power dissipation. Even with matching hold current, these secondary parameters can affect circuit behavior and should be reviewed in the datasheets.

TLC-NSMD005 Alternatives, Datasheet & Cross Reference | TLC Electronic
