2.50mm pitch single-row header with latch holder
The 6-1971798-2 is a 6-position, single-row header from the TE Grace Inertia (GIC) series, designed for board-to-cable/wire applications. Its 2.50mm pitch sets the PCB footprint and the per-contact current ceiling—at the rated current the temperature rise stays within the UL94 V-0 housing material limits. The shrouded 4-wall design protects the square male pins from bending during mating and guides the receptacle into alignment, reducing mis-mate risk in blind or high-vibration assemblies. A latch holder fastening type locks the mated pair together, providing vibration resistance suitable for automotive, industrial control, and appliance harnesses where the connector sees movement or shock.
Tin contacts and through-hole termination
The kinked pin solder tails provide retention during wave soldering and a reliable mechanical anchor.
