The TE Connectivity 1-1981971-2 is an 8-circuit, dual-row receptacle housing from the Grace Inertia (GIC) series, designed for wire-to-board and wire-to-wire power interconnects in automotive, industrial, and appliance harnesses. The 2.50 mm pitch is a common industrial spacing that balances current capacity against board real estate — each circuit can carry moderate power without forcing an oversized footprint. The locking ramp fastening type provides a positive audible click when mated, holding the connection secure against vibration in vehicle and machinery applications. The red colour aids quick visual identification on the assembly line or during field service — a simple but effective anti-mis-mating cue when multiple connector families share a harness.
Contacts Not Included — What You Need to Order Separately
This housing ships without contacts — the receptacle accepts crimp terminals (tab contact type) ordered separately.
Mating Half and Panel Fit
The 1-1981971-2 receptacle mates with the Grace Inertia plug header, typically the TE 1-1981970-x series (x = position count). Both use the 2.50 mm pitch and dual-row layout, so the 8-circuit plug header is the direct match. The locking ramp on the receptacle engages with the corresponding latch on the plug — the connection is free-hanging (in-line), so no panel cutout is needed. For board-mounted applications, the plug header is through-hole or surface-mount; the receptacle terminates the wire harness and mates to it. The row spacing of 0.299" (7.60 mm) is wider than the pitch, giving the dual-row layout enough separation for the locking mechanism and wire strain relief.
