Product details

2.50 mm pitch, 3-position single-row header

Board-to-cable style with kinked pin solder termination

The board-to-cable/wire style means this header connects a PCB to a wire harness via a mating receptacle (not a board-to-board mezzanine). Termination is through-hole with kinked pins — the kink provides retention during soldering and prevents the header from falling out during wave solder. A board guide feature aids alignment during assembly, reducing the risk of pin damage when mating the harness. The insulation height of 0.346" (8.80 mm) gives clearance for the latch mechanism and the mating receptacle housing.

Frequently asked questions

What connects to 3-1971800-4?

This header mates with a Grace Inertia series receptacle housing that accepts the corresponding crimp terminals. The latch holder on the header engages with the latch on the receptacle for secure mating. Confirm the receptacle part number and terminal wire gauge against your harness design.
