Best Alternatives to HC-HY-4A

Package: Through HoleHCTLInterconnectsNumber of Positions: 4Pitch: 2.00 mmCurrent Rating: 2 AVoltage Rating: 250 VMounting Type: Through Hole

HC-HY-4A is a 4-pin, 2.0mm pitch straight through-hole header. When seeking alternatives, focus on matching the 250V/2A rating and verifying mechanical compatibility, especially the connector series.

AI replacement insight

Package riskhigh

Connector series (e.g., PH vs HY) determines mating compatibility and is the primary risk.

Electrical riskmedium

Some candidates have lower voltage ratings. Always verify against application requirements.

Can it be replaced directly?

No drop-in replacement is confirmed without a mechanical drawing comparison. Several parts are electrically similar, but form factor differences (e.g., connector series) must be checked.

Best replacement path

WF-1A200A4P-Y is the most promising path, but requires datasheet review for mechanical fit.

Main risk

Mechanical incompatibility due to different connector series (e.g., PH vs. HY) preventing proper mating.
