The 1776489-6: It mates with standard 5.00 mm pitch female socket housings or terminal block plugs, providing a solder-to-board interconnect for power or signal distribution. Rated 10 A at 250 V per UL, with tin-plated brass contacts, this header suits moderate-current applications where the mating cycle count stays under 50 — typical for fixed wiring in control panels, lighting fixtures, and industrial equipment. The vertical through-hole orientation and 0.138" (3.50mm) contact tail length fit standard PCB hole patterns for wave or hand soldering. Insulation height is only 0.079" (2.00mm), keeping the header low-profile above the board.
At 0.197" (5.00mm) pitch, this header matches the industry-standard spacing for many terminal block connectors and PCB-mount receptacles. The 6 positions in a single level mean the board footprint occupies a 1.0" (25.4mm) row of plated through-holes.
Current, Voltage, and Thermal Limits
The 10 A per contact rating at 250 V is the maximum continuous load under UL conditions. Derate current if ambient temperature exceeds 105°C or if multiple adjacent contacts are fully loaded — the housing material (PA66, UL94 V-0) limits the temperature rise.
