Is there a pin-compatible replacement for HC-HY-2Y?

No pin-compatible replacement has been confirmed. While some alternatives share the 2.0mm pitch and 2-pin layout, their full mechanical drawings must be compared to ensure they fit the same PCB footprint.

What risks should I check before replacing HC-HY-2Y?

Key risks include mismatched electrical ratings (voltage and current), mechanical incompatibility (housing dimensions, height, footprint), and material differences. Always verify the candidate's datasheet against your design requirements.

HC-HY-2Y Alternatives, Datasheet & Cross Reference | HCTL

Finding a substitute for the HC-HY-2Y, a 2-pin 2.0mm pitch female header, requires careful review of electrical ratings and mechanical dimensions. While some alternatives exist, they may have lower voltage or current ratings, necessitating engineering validation.

AI replacement insight

Electrical riskhigh

Candidates have lower voltage or current ratings, requiring circuit analysis.

Package riskmedium

Mechanical drawings must be compared to ensure footprint and mating compatibility.

Can it be replaced directly?

No direct, verified drop-in replacement for the HC-HY-2Y is available. All potential alternatives require engineering review due to parametric or mechanical differences.

Best replacement path

Review candidates with downgraded electricals like WF-1D200A2P (lower voltage) or PM200-1-02-Z-4.3 (lower current), and perform a full datasheet comparison for mechanical fit.

Main risk

The primary risk is electrical stress from using a part with a lower voltage or current rating, and mechanical incompatibility preventing proper assembly.

Recommended alternatives

A 2-pin, 2.0mm pitch female header with a lower current rating that requires careful engineering review.
