Is there a pin-compatible replacement for HC-VH-4ALT?

While several parts share the same 4-pin, 3.96mm pitch vertical format, true pin-to-pin compatibility requires careful comparison of datasheet mechanical drawings. JST's B4P-VH-B(LF)(SN) is a likely form-fit match that needs verification.

What risks should I check before replacing HC-VH-4ALT?

The main risks are mechanical fit and electrical rating. Ensure the replacement has a vertical/straight mounting style, not right-angle. Also, verify the current rating is 7A or higher; some alternatives may have a lower rating.

HC-VH-4ALT Alternatives, Datasheet & Cross Reference | HCTL

HC-VH-4ALT is a 4-pin, 3.96mm pitch vertical through-hole header from HCTL, rated for 7A and 250V. Key considerations for finding a replacement are matching the vertical mounting orientation and meeting the 7A current rating.

AI replacement insight

Electrical risklow

Low, if selecting a part with >=7A current rating.

Package riskmedium

Subtle differences in shroud dimensions or PCB footprint between manufacturers can cause assembly issues.

Sourcing risklow

The 3.96mm header is a common form factor with multiple sources.

Can it be replaced directly?

There is no confirmed direct drop-in replacement. The closest options, like JST's B4P-VH-B(LF)(SN), are strong functional matches but require datasheet review to confirm mechanical interchangeability.

Best replacement path

Cross-referencing to the JST VH series, specifically B4P-VH-B(LF)(SN), which offers upgraded current specs. Verification of the PCB footprint is required.

Main risk

The primary risk is selecting a connector with the wrong mounting orientation (right-angle instead of vertical) or a lower current rating.

Recommended alternatives

JST VH series vertical header with higher current rating; review datasheet for footprint compatibility.
