Is there a pin-compatible replacement for HC-GH-4PWT?

No replacement has been pre-verified as 100% pin-compatible without a layout check. However, ZX-GH1.25-WT4 and XD-1.25-4PWT are strong candidates that match the form factor (right-angle SMT) and pin configuration. A review of the mechanical drawings is required to confirm pin-to-pin compatibility.

What risks should I check before replacing HC-GH-4PWT?

Before replacing HC-GH-4PWT, you must check three main things: 1) Mechanical Fit: Compare the candidate's datasheet drawing to your PCB layout. 2) Mating Connector: Ensure the replacement works with your existing cable or female connector. 3) Material/Plating: Check for any specific material requirements in your application.

HC-GH-4PWT Alternatives, Datasheet & Cross Reference | HCTL

HC-GH-4PWT is a 4-pin, 1.25mm pitch right-angle SMT header used in wire-to-board applications. While no drop-in replacement is pre-verified, several strong functional alternatives exist with matching electrical ratings and form factors, requiring only a final check of mechanical drawings for confirmation.

AI replacement insight

Package riskmedium

PCB footprint and mechanical dimensions must be verified from datasheet drawings to ensure fit.

Electrical risklow

Recommended alternatives have matching or better voltage and current ratings.

Sourcing risklow

Multiple manufacturers produce connectors in this common form factor, providing sourcing flexibility.

Can it be replaced directly?

There are several strong functional alternatives, but no drop-in replacement has been verified. ZX-GH1.25-WT4 and XD-1.25-4PWT are the most promising candidates, pending footprint verification.

Best replacement path

Review the datasheets for ZX-GH1.25-WT4 and XD-1.25-4PWT. Compare the mechanical drawings to your PCB layout to confirm a footprint match before ordering.

Main risk

The primary risk is a mechanical mismatch. While key parameters align, the exact PCB footprint, connector height, and locking features can vary between manufacturers and must be checked.

Recommended alternatives

A 4-pin, 1.25mm pitch right-angle SMT header with a higher voltage rating. Verify footprint before use.
