The JST XARR-14V is a 14-position, single-row receptacle housing from the XA series. It uses a 2.50 mm pitch and a latch lock for positive retention when mated with the corresponding XA series pin header. The housing is molded in natural polyamide nylon and mounts into a panel cutout with snap-in clips — no hardware needed. Typical applications include internal wire-to-board harnesses in appliances, office equipment, and industrial control panels where a compact, keyed connector is needed.
The 2.50 mm Pitch and What It Means for Your Layout
The 2.50 mm pitch is the center-to-center spacing between adjacent contact cavities. It sets the footprint for the mating header and the board layout.
Contacts Not Included — Plan the Crimp Terminal Order
The XARR-14V ships as an empty housing — no contacts are included. You need to order the matching male pin crimp terminals separately. The housing accepts the standard XA series crimp contacts, which are terminated to discrete wires before insertion. If the crimp terminals are not on the BOM alongside the housing, the harness build stops. Order them at the same time.
