VH3.96mm Connectors, Cables & PCB Headers
VH3.96mm Connectors, Cables & PCB Headers
VH3.96mm describes the 3.96mm-pitch, single-row locking connector format represented in this collection. The 21 products include wire housings, crimp terminals, straight and right-angle PCB headers, pre-crimped leads, extension cables, mating wire pairs, connector kits and selected motherboard switch harnesses.
Several listings contain many connector families. Choose the VH3.96mm option explicitly; specifications belonging to SH, ZH, PH, XH or other pitches do not apply to VH products.
Product Range
- Loose housings and crimp terminals
- Straight and right-angle through-hole PCB headers
- Selected single-ended and double-ended 18AWG, 20AWG and 22AWG cables
- Male-to-female extension leads and mating cable pairs
- Housing, contact and header kits
- 3-position power-switch harnesses and leads terminating in 2.8mm, 4.8mm or 6.3mm blade receptacles
Compatibility Boundary
VH3.96mm is commonly used as a search term for the JST VH format, but pitch alone does not prove interchangeability or original-brand status. Verify housing profile, latch, polarization, terminal cavity, mating depth and PCB footprint before mixing parts from different suppliers.
How to Select
- Confirm 3.96mm center-to-center pitch and a single-row layout.
- Match the position count, housing key and latch location.
- Choose housing, terminals, complete kit, cable assembly or PCB header.
- Select straight or right-angle mounting after checking board and enclosure clearance.
- Match contacts to the exact conductor and insulation diameter.
- For cables, confirm gauge, length, end type, conductor order and package quantity.
- For mixed listings, verify that VH3.96mm is the selected family.
Wire-to-Board, Wire-to-Wire and Blade Leads
A wire housing plus PCB header forms a wire-to-board connection. Mating cable housings form a wire-to-wire extension. VH-to-blade leads are a different assembly: the blade width and mating terminal must be checked separately and must not be inferred from the VH pitch.
Pinout and Crimping
Inspect orientation from the mating face, then verify continuity before applying power. Wire color is not a universal pinout standard. Use a suitable open-barrel crimp tool and confirm conductor crimp, insulation support and terminal retention with a light pull test.
Electrical and Compliance Boundaries
No single current, voltage, wire range, material, plating, temperature or certification applies to every item. Claims such as 7A, 250V, AWG 14–20, PA66, RoHS or REACH must be confirmed for the exact product and assembled circuit. Current capacity also depends on contact, wire, loaded circuits, temperature rise and installation.
Typical Applications
Properly matched parts can support internal wiring in appliances, control boards, power supplies, LED equipment, prototypes and low-voltage harnesses. Industrial, mains-adjacent, motor, battery and safety-critical use requires independent validation of ratings, spacing, retention and compliance.
Frequently Asked Questions
Are all products genuine JST VH parts?
No collection-wide original-brand claim is made. Yoeruyo is the listed brand.
Can any 3.96mm housing mate with these headers?
No. Compare the complete mechanical interface and terminal system.
Does every listing include terminals and a PCB header?
No. Some options contain only one component or a pre-wired cable.
Are all cables the same gauge?
No. Reviewed listings include selected 18AWG, 20AWG and 22AWG options.
Are VH-to-blade cables universal?
No. Verify blade width, gender, wire size and pinout.
Ordering Checklist
Confirm pitch, positions, housing and latch, terminal, wire gauge, cable length, pinout, PCB footprint, header orientation, blade width where relevant, ratings, contents and quantity. Validate a sample before production use.
