The JST VHR-8N is the 8-circuit receptacle housing from the VH series, a wire-to-board or wire-to-wire interconnect family built around a 0.156" (3.96mm) pitch.
Wiring and Termination — The Contacts Trap
Selection Check — Pitch and Position Count
Within the VH series, the 8-position VHR-8N is one of several circuit counts available; the key selection decision is matching the position count to the harness circuit count and confirming the header pitch is identical. The single-row layout keeps the housing narrow, which helps in tight enclosures where a dual-row housing would not fit.
