Is there a pin-compatible replacement for HC-1.25-8PLT?

No verified pin-to-pin replacement is available. Candidates like HCZZ0015-8 appear to have a compatible form factor (vertical SMT, 1.25mm pitch), but require datasheet comparison to confirm the exact PCB layout.

What risks should I check before replacing HC-1.25-8PLT?

Key risks are electrical and mechanical. Ensure the substitute's voltage and current ratings meet your application's needs, as most alternatives are lower than the target's 250V/2A. Also, confirm the PCB footprint matches your design.

HC-1.25-8PLT Alternatives, Datasheet & Cross Reference | HCTL

HC-1.25-8PLT is an 8-pin, 1.25mm pitch vertical SMT header. While direct replacements are not confirmed, several parametric alternatives exist with similar form factors but lower electrical ratings that require careful review.

AI replacement insight

Electrical riskhigh

Most alternatives have significantly lower voltage/current ratings.

Package riskmedium

Footprints for 'PicoBlade compatible' connectors can vary slightly. Verification is required.

Can it be replaced directly?

No direct, verified pin-to-pin replacement for HC-1.25-8PLT has been identified. All candidates require review of mechanical footprint and electrical ratings.

Best replacement path

For applications tolerating lower ratings, HCZZ0015-8 offers a similar form factor. For brand reliability, JST's SM08B-GHS-TB(LF)(SN) is an option, but with significant downgrades.

Main risk

The primary risk is substituting a part with lower voltage and current ratings (e.g., 1A/125V vs. the target's 2A/250V), which could cause component failure.

Recommended alternatives

A cross-family alternative from JST with similar form factor but significantly lower electrical ratings.

Questions & answers

There is no single best alternative. HCZZ0015-8 is a strong candidate if lower 1A/125V ratings are acceptable. JST's SM08B-GHS-TB(LF)(SN) is a reliable option but with even lower 1A/50V ratings. Always verify footprint and electrical specs.
