Product details

Tin is cost-effective for moderate-duty signal connections but limits mating cycles to roughly 50 before fretting corrosion may increase contact resistance — fine for one-time assembly or infrequent disconnect in indoor equipment.

Mounting and Board Fit Details

This is a through-hole header with a press-fit, solder termination — the press-fit feature holds the component in place during wave soldering, reducing tombstoning risk. The mated stack height is 11.3mm, meaning the mated pair occupies that vertical space above the board. The insulation height of 0.346" (8.80mm) is the header body height alone; plan your enclosure clearance accordingly. A board guide feature assists alignment during assembly, useful for automated pick-and-place or manual insertion into tight enclosures.

Frequently asked questions

What connector mates with B14B-XASK-1-A?

This header mates with JST XA series crimp receptacles (female housings with crimp terminals). The 2.50mm pitch and locking ramp are specific to the XA series; confirm the mating half part number from the JST XA family.
