Product details

The B2B-XH-A-GU: That pitch sets the PCB layout — the hole pattern and trace routing — and the 2 positions define the circuit count for the BOM line.

Comparing the Gold-Plated Variant to Tin Peers

The B2B-XH-A-GU differs from the standard B2B-XH-A and B2B-XH-A(LF)(SN) in one critical dimension: the mating contact finish. The -GU suffix specifies gold plating (16.0 µinch) versus the tin plating on the base B2B-XH-A. For applications requiring higher mating cycle endurance or better corrosion resistance, the gold variant is the correct choice. The B2B-XH-AM(LF)(SN) adds a board guide feature but retains tin plating.

Frequently asked questions

What is the equivalent or replacement for B2B-XH-A-GU?

The closest functional equivalent within the XH series is the B2B-XH-A, which has the same 2-position, 2.50 mm pitch, and through-hole mounting, but with tin plating on the mating contact instead of gold. For gold plating, the B2B-XH-A-GU is the specified variant.
