Is there a pin-compatible replacement for HC-HY-8A?

Yes, parts like B08B-PASK-1(LF)(SN) and ZX-HY2.0-8PLT appear to be pin-compatible based on datasheet specifications (8-pin, 1-row, 2.0mm pitch). Always verify the PCB footprint and mechanical fit before production.

What risks should I check before replacing HC-HY-8A?

The main risk is mating connector incompatibility. Different connector families may not securely connect. Also, check the substitute's datasheet for any minor differences in footprint dimensions or housing size.

HC-HY-8A Alternatives, Datasheet & Cross Reference | HCTL

HC-HY-8A is a standard 8-pin, 2.0mm pitch single-row straight header. Finding a replacement involves matching these key dimensions and ensuring the substitute offers at least a 2A, 250V rating.

AI replacement insight

Package riskmedium

Subtle dimensional differences between manufacturers can affect PCB fit or housing compatibility.

Electrical risklow

Proposed alternatives have matching or superior voltage and current ratings.

Sourcing risklow

This is a common connector type with multiple manufacturers.

Can it be replaced directly?

Yes, parts like JST's B08B-PASK-1(LF)(SN) offer a strong functional replacement, but require verification of mating connector compatibility.

Best replacement path

Cross-vendor functional alternatives with matching form-factor and equal or better electrical ratings are widely available.

Main risk

The primary risk is mechanical incompatibility with the existing female mating connector, as different connector series are not guaranteed to inter-mate correctly.

Recommended alternatives

A strong alternative with matching form-factor and superior current rating.
