2.50mm pitch, 6-position header for Grace Inertia wire-to-board
The 6-1971798-1: This is a 6-position, single-row male header from TE's Grace Inertia (GIC) series, designed for board-to-cable/wire applications. The 2.50mm pitch sets the board footprint and mates with the corresponding Grace Inertia receptacle housings. The shrouded 4-wall design protects the square pins during handling and guides the mating connector into alignment, reducing the risk of bent contacts in assembly. Rated at 50V, this header is suited for low-voltage signal and power distribution inside equipment enclosures. The current rating varies by wire gauge used in the mating half, so the limiting factor is the terminal and wire size, not the header pin itself. The latch holder fastening type locks the mated pair together, providing resistance against vibration and accidental disconnection — a practical advantage in applications where the cable sees movement or strain.
Mounting and termination — through-hole with kinked solder tails
The header mounts through-hole with kinked, tin-plated solder tails. The kinked pins provide retention during wave soldering before the solder solidifies.
