Is there a pin-compatible replacement for VH-5A?

Yes, B5P-VH(LF)(SN) and HC-VH-5A5 are strong candidates for pin-compatible replacement. They share the same 5-pin, 3.96mm pitch, and through-hole package. However, always verify the datasheet's mechanical drawing.

What risks should I check before replacing VH-5A?

The main risk is electrical. You must ensure the replacement's current rating is at least 5A. Some compatible parts, like ZX-VH3.96-5PZZ, have a lower rating (3A) and could fail in your application.

VH-5A Alternatives, Datasheet & Cross Reference | CAX

The VH-5A is a standard 5-pin, 3.96mm pitch header for wire-to-board connections. Several compatible alternatives exist, including upgraded options from JST, the original series designer.

AI replacement insight

Package risklow

The 3.96mm VH header is a widely standardized footprint.

Electrical riskmedium

Current rating must be verified. Some clones have lower ratings.

Sourcing risklow

Multiple vendors manufacture compatible parts, ensuring good availability.

Can it be replaced directly?

Yes, several direct replacements for the VH-5A exist. B5P-VH(LF)(SN) and HC-VH-5A5 are strong candidates with matching form-fit and equal or better current ratings.

Best replacement path

The JST B5P-VH(LF)(SN) is the best choice, as it's from the original series designer and offers a higher 10A current rating.

Main risk

The primary risk is substituting with a part that has a lower current rating, which can lead to overheating and failure if the application draws close to the original's 5A limit.

Recommended alternatives

JST's original VH series header with a higher 10A current rating. A strong, upgraded alternative.
