Is there a pin-compatible replacement for HC-VH-2A2-R?

Yes, parts like KH-VH-2P-Z are highly likely to be pin-compatible replacements. They share the same 3.96mm pitch, 2-pin vertical configuration, and key material specs. However, confirming pin-to-pin compatibility requires comparing the mechanical drawings in the datasheets.

What risks should I check before replacing HC-VH-2A2-R?

Before replacing HC-VH-2A2-R, you must check the mechanical dimensions from the candidate's datasheet to ensure it fits your PCB layout. Also, confirm that any material differences (e.g., LCP vs. Nylon66) are acceptable for your application's temperature and assembly process.

HC-VH-2A2-R Alternatives, Datasheet & Cross Reference | HCTL

Finding a substitute for the HC-VH-2A2-R, a 2-pin 3.96mm pitch straight header, involves matching its 7A current rating and vertical through-hole package. Several strong functional alternatives exist from various manufacturers.

AI replacement insight

Electrical risklow

Several candidates match the 7A current and 250V voltage ratings.

Package riskmedium

Candidates match the through-hole vertical format, but datasheet comparison is required to confirm exact dimensions for pin-to-pin compatibility.

Sourcing risklow

This is a common connector style with multiple vendors available, reducing sourcing risk.

Can it be replaced directly?

Yes, several functional alternatives exist for HC-VH-2A2-R, such as KH-VH-2P-Z and ZX-VH-3.96-2PLT. They match the 3.96mm pitch, 2-pin configuration, and 7A/250V rating.

Best replacement path

KH-VH-2P-Z from Kinghelm is a very strong candidate, matching all key electrical and material specifications. HC-VH-2ALT from the same manufacturer is also an excellent option.

Main risk

The primary risk is ensuring the mechanical footprint and pin dimensions are identical. While the pitch and orientation match, slight variations in housing size could affect board layout or mating.

Recommended alternatives

A variant from the same manufacturer with matching specs but different housing material (LCP).
