JST XHP-2

Product FAQ

• 1. What voltage rating, current capacity, and wire gauge ranges govern the JST XHP-2 housing?
  The JST XHP-2 wire-to-board socket housing is rated for a maximum voltage of 250V AC/DC and a continuous current capacity of up to 3A AC/DC when used with AWG #22 conductors. It accepts compatible crimp socket contacts, including the SXH-001T-P0.6 and SXH-002T-P0.6 series, supporting wire sizes from AWG #30 to #22 (0.05–0.33 mm², depending on contact type) with insulation outer diameters ranging from 0.9 mm to 1.9 mm.
• 2. Which pin pitch, position count, housing material, and flammability ratings define the XHP-2?
  The XHP-2 features a 2.5 mm pitch in a single-row, 2-position configuration. It is molded from natural white PA6 (Nylon 6) with a UL94V-0 flammability rating. The datasheet lists the housing dimensions for the XHP-2 as A = 2.5 mm, B = 5.7 mm, and C = 7.3 mm.
• 3. Which PCB headers and crimp contacts pair directly with the XHP-2 housing?
  The XHP-2 receptacle housing is compatible with the 2-circuit JST XH-series through-hole PCB headers, including the B2B-XH-A top-entry and S2B-XH-A side-entry headers. It accepts SXH-001T-P0.6 and SXH-002T-P0.6 crimp contacts for wire termination.
• 4. What operating temperature limits, insulation resistance, and dielectric specifications apply to the XHP-2 housing?
  The XHP-2 is specified for an operating temperature range of −25°C to +85°C, including temperature rise during current flow. The connector system provides an initial contact resistance of 10 mΩ maximum, an insulation resistance of at least 1,000 MΩ, and a withstanding voltage of 1,000 VAC for one minute.
• 5. How is the XHP-2 housing used during PCB assembly?
  The XHP-2 is a cable-side crimp housing and is not mounted directly to a printed circuit board. Instead, it mates with compatible 2-circuit JST XH-series through-hole PCB headers, such as the B2B-XH-A and S2B-XH-A, while the electrical connection to the wire is made using compatible SXH-series crimp contacts.
