Is there a pin-compatible replacement for HC-XH-7A-G?

Potentially, yes. Parts like HC-XHB-7A from the same manufacturer are strong candidates for being pin-compatible. However, a full datasheet review of mechanical drawings is required to confirm pin-to-pin compatibility.

What risks should I check before replacing HC-XH-7A-G?

Key risks include mechanical mismatches in housing dimensions, pin length, or PCB footprint, even if pitch and pin count match. Also, ensure the substitute is compatible with the intended mating connector.

HC-XH-7A-G Alternatives, Datasheet & Cross Reference | HCTL

HC-XH-7A-G is a 7-pin, 2.50mm pitch straight through-hole header from HCTL's XH series. Alternatives must match these critical mechanical and electrical specifications for proper fit and function.

AI replacement insight

Package riskmedium

Requires datasheet review to confirm mechanical drawings and footprint.

Electrical risklow

Key electrical ratings are standard and easily matched by candidates.

Can it be replaced directly?

No drop-in replacement is confirmed without a datasheet review. HCTL's HC-XHB-7A is the most promising candidate for a direct replacement.

Best replacement path

Source a cross-vendor XH-series compatible header like XD-XH-7A-G or the manufacturer variant HC-XHB-7A.

Main risk

Mechanical incompatibility is the main risk. Pitch, orientation, and housing dimensions must be identical.

Recommended alternatives

Very strong alternative from the same manufacturer with a near-identical part number.
