Product details

The B8B-XH-A: The shrouded 4-wall design protects the male pins from bending during handling and mis-mating — a practical advantage when the board is serviced in the field. Rated 3 A per contact at 250 V, with a detent lock that gives a positive tactile click on mating.

Through-hole press-fit with solder termination

Termination is press-fit, solder — the pin is pressed into the plated through-hole and then wave-soldered. The contact length-post of 0.134" (3.40 mm) suits standard PCBs.

Board-to-cable style with 9.8 mm mated stack height

Style is Board to Cable/Wire — the header mates with the XH series crimp-style receptacle housing. The mated stack height is 9.8 mm, which sets the z-height budget when the cable exits the connector. The detent lock holds the pair together under moderate vibration.

Frequently asked questions

What is the pin pitch of B8B-XH-A?

The mating pitch is 0.098" (2.50 mm). This is the center-to-center spacing between adjacent pins.

Is B8B-XH-A a shrouded header?

Yes, it is shrouded with a 4-wall design. The shroud protects the male pins from damage and guides the mating receptacle into alignment.

What is the difference between B8B-XH-A and B8B-XH-A(LF)(SN)?

The two parts share the same form, fit, and function — same pitch, position count, shrouding, and current rating. The difference is RoHS compliance: B8B-XH-A is RoHS non-compliant, while B8B-XH-A(LF)(SN) carries RoHS-compliant plating.
