Is there a pin-compatible replacement for HC-1.25-3PLT?

No fully verified pin-compatible replacement is available. While parts like WAFER-GH1.25-3PLB have a similar vertical SMT form factor, their electrical ratings are much lower and require careful design review.

What risks should I check before replacing HC-1.25-3PLT?

Primarily check the voltage and current ratings; many alternatives are rated for 1A/125V, not 2A/250V. Also, verify the mechanical footprint and orientation (vertical vs. right-angle) from the datasheet drawing.

HC-1.25-3PLT Alternatives, Datasheet & Cross Reference | HCTL

HC-1.25-3PLT is a 3-pin, 1.25mm pitch vertical SMT header from HCTL, rated for 2A and 250V. Finding a direct drop-in replacement requires careful verification of mechanical footprint and electrical ratings.

AI replacement insight

Electrical riskhigh

Many alternatives have significantly lower current and voltage ratings.

Package riskmedium

Orientation (vertical vs. right-angle) and exact footprint must be verified from datasheets.

Can it be replaced directly?

No direct pin-to-pin replacement has been identified. Candidates with a matching vertical orientation have significantly lower electrical ratings, posing a high risk.

Best replacement path

The best path is to use a functional alternative like HC-1.25-3PWT if a right-angle orientation is acceptable, as it matches all electrical specifications.

Main risk

The main risk is electrical overstress, as many similar-looking connectors have much lower voltage and current ratings (e.g., 1A/125V vs. 2A/250V).

Recommended alternatives

A functional alternative from the same series with identical electrical ratings but a right-angle orientation.
