Product details

2.50 mm pitch, 4-position header from the Grace Inertia GIC series

A built-in board guide on the housing helps align the mating receptacle during assembly.

How it compares to nearby siblings

Compared to the CT series header 1-292164-1, this GIC part uses a wider 2.50 mm pitch versus 2.00 mm, which gives more room for routing between pads on the board. The CT header is a right-angle variant, while this one is vertical through-hole — choose the orientation that fits your board-edge cable exit. Against the 1-2232960-3 (also 2.50 mm pitch but 3 positions), this 4-position version adds one more circuit for applications needing an extra signal or power line. Both use tin contacts and a shrouded 4-wall design, so the mating receptacle family is the same.

Frequently asked questions

What is the mating connector for 4-1971798-1?

This header mates with a Grace Inertia (GIC) series receptacle housing that accepts 2.50 mm pitch crimp terminals. The mating half is a 4-position, single-row, fully shrouded receptacle with a latch holder — confirm the specific receptacle part number from the GIC series that matches your wire gauge and seal requirements.
