Product details

2.50 mm pitch, 3-position shrouded header for XH series

This z-height budget must be accounted for in enclosure design when the header is paired with an XH series crimp housing. The insulation height of 0.276" (7.00 mm) and contact post length of 0.134" (3.40 mm) define the PCB keep-out and solder tail clearance.

RoHS non-compliant per the listed status — verify your assembly's regulatory requirements.

Mating compatibility with XH series housings

This header mates with JST XH series crimp receptacles (e.g., XHP-3) using the matching crimp terminal (SXH-001T-P0.6). The detent lock engages with the housing latch for a secure connection.

Frequently asked questions

What is the compatible housing for the B3B-XH-A?

The B3B-XH-A mates with JST XH series crimp housings such as XHP-3, using the SXH-001T-P0.6 crimp terminal. The detent lock provides a vibration-resistant connection.

What are the alternatives to the B3B-XH-A?

The B3B-XH-AM adds a board guide; the BH3B-XH-2 is functionally identical. All three are active and share the same 3-position, 2.50 mm pitch, 3 A/250 V rating.
