Best Alternatives to HC-HY-3A

Package: Through HoleHCTLInterconnectsNumber of Positions: 3Pitch: 2.0 mmCurrent Rating: 2 AVoltage Rating: 250 VMounting Type: Through Hole

HC-HY-3A is a common 3-pin, 2.0mm pitch straight through-hole header. Several form-fit-function alternatives are available, but require datasheet verification for mechanical footprint and mating compatibility.

AI replacement insight

Package riskmedium

While pitch and orientation match, housing dimensions and pin lengths can vary. Datasheet comparison is essential.

Electrical risklow

For candidates with matching ratings, electrical risk is low. Avoid parts with lower voltage ratings.

Can it be replaced directly?

No drop-in replacement has been verified. However, several candidates like WF-1E200A3P match key electrical and mechanical specifications and are likely compatible after review.

Best replacement path

Use a form-fit-function candidate like WF-1E200A3P or WAFER-PH200Z-3A after verifying the mechanical drawing in the datasheet.

Main risk

Mechanical footprint mismatch.
