Buying Guide – Selecting the Right VH3.96mm Component
- Circuit count – select the number of circuits to match your wiring requirements; available from 2 to 12 positions
- Wire gauge – confirm the crimp terminal's wire range (AWG 20–14 / 0.5–2.0mm²) matches your cable specification before ordering
- PCB header orientation – vertical for standard wire-to-board connections; right-angle for edge-mount and space-constrained PCB layouts
- Pre-crimped assemblies – for OEM integration, pre-crimped wire assemblies eliminate crimping tool requirements and reduce assembly time
- Compatibility check – verify housing and header dimensions match JST VH series before ordering for drop-in replacement applications
Frequently Asked Questions
Is VH3.96mm compatible with JST VH series connectors?
Yes. Yoeruyo VH3.96mm housings and PCB headers are dimensionally compatible with JST VH series connectors. They mate correctly with genuine JST VH counterparts, making them suitable for drop-in replacement and compatible system expansion.
What is the current rating per contact?
The VH3.96mm terminal is rated at 7A per contact. For multi-circuit power applications, distribute the load across multiple contacts if the total current exceeds 7A per circuit.
What wire gauge is supported?
VH3.96mm crimp terminals accept wire from AWG 20 to AWG 14 (0.5mm² to 2.0mm²). Always match the terminal crimp barrel to your wire gauge for a reliable, low-resistance connection.
Do you offer pre-crimped wire assemblies?
Yes. Custom wire-to-connector assemblies with pre-crimped VH3.96mm terminals are available in specified wire lengths, gauges, and circuit counts. Contact us for OEM assembly quotations and lead times.
Do you offer bulk pricing for equipment manufacturers?
Yes. Yoeruyo offers tiered pricing for orders of 500 units or more. Contact us for volume quotations, mixed-SKU orders, and OEM packaging options for production line integration.
