Best Alternatives to HC-XH-4Y

Package: 2.5mm Pitch HeaderHCTLInterconnectsNumber of Positions: 4Pitch: 2.5 mmCurrent Rating: 3 AVoltage Rating: 250 VOperating Temperature: -25°C to +85°C

HC-XH-4Y is a 4-pin, 2.5mm pitch straight header from HCTL, used in wire-to-board connections. Finding a substitute requires matching the pitch, pin count, orientation, and 3A/250V electrical ratings.

AI replacement insight

Package riskmedium

Footprint must be verified from datasheet.

Electrical risklow

Key ratings are common, but must be confirmed.

Sourcing risklow

XH series connectors are widely available from multiple vendors.

Can it be replaced directly?

Direct replacement for HC-XH-4Y should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Find an XH-series compatible, 4-pin, 2.5mm pitch straight header with a UL94-V0 rating, like Megastar's ZX-XH2.54-4PZZ-Y, after verifying its datasheet.

Main risk

The main risk is mechanical incompatibility, where a substitute's PCB footprint or housing dimensions differ, preventing a proper fit.
