Is there a pin-compatible replacement for HC-1.25-5PLT?

WAFER-GH1.25-5PLB appears to be mechanically similar, but its lower electrical ratings (1A/125V vs 2A/250V) prevent it from being a direct pin-compatible replacement without significant design review.

What risks should I check before replacing HC-1.25-5PLT?

The primary risks are electrical. Verify the candidate's voltage and current ratings meet or exceed the target's 250V and 2A. Also, confirm the mechanical footprint and dimensions from the datasheets match your PCB layout.

HC-1.25-5PLT Alternatives, Datasheet & Cross Reference | HCTL
