Is there a pin-compatible replacement for HC-1.25-10PWT?

Candidates with matching pin count, pitch, and mounting exist, but have weaker electrical ratings. A full pinout and footprint comparison from datasheets is required to confirm pin compatibility.

What risks should I check before replacing HC-1.25-10PWT?

Key risks include lower voltage and current ratings, and potential mechanical differences in body size or features like shrouds. Always verify the candidate's datasheet against your board layout and electrical requirements.

HC-1.25-10PWT Alternatives, Datasheet & Cross Reference | HCTL

HC-1.25-10PWT is a 10-pin, 1.25mm pitch right-angle SMT header from HCTL, rated for 2A and 250V. Finding a direct drop-in replacement requires careful review of mechanical and electrical specifications.

AI replacement insight

Electrical riskhigh

All form-factor candidates have significantly lower voltage and/or current ratings.

Package riskmedium

Footprints and mechanical outlines (e.g., shrouds) must be verified from datasheets.

Can it be replaced directly?

No direct, fully-rated replacement was identified. Alternatives require accepting lower voltage and current ratings, and careful mechanical verification.

Best replacement path

Parametric alternatives with matching form factor but lower electrical ratings.

Main risk

Electrical overstress due to candidates having significantly lower voltage and current ratings than the target.

Recommended alternatives

A 10-pin, 1.25mm pitch, right-angle SMT header with lower voltage and current ratings. Verify electrical compatibility.
