This is standard for JST XA series housings; the buyer selects the wire gauge and plating grade (tin or gold) that matches the application's current and environmental requirements.
The XARP-03V mates with the corresponding JST XA series pin header (through-hole or SMT, straight or right-angle, depending on board layout). The 2.50mm pitch and latch lock are common across the XA family, so the header must match the 3-position, single-row layout. For the female contacts, JST offers crimp terminals in the XA series — typically tin-plated for standard duty or gold-plated for higher mating cycle counts or corrosive environments. The housing accepts the wire range specified for those terminals; the datasheet lists the exact strip length and crimp tooling.
Position Count Options Across the XA Series
The XARP-03V is the 3-position member of the XA receptacle housing family. Siblings include the XARP-05V (5 positions), XARP-06V (6 positions), and XARP-08V (8 positions) — all sharing the same 2.50mm pitch, single-row layout, latch lock, natural PA66 material, and crimp termination. No other spec changes across the range — one family, fewer SKUs.
