Right-angle 8-position header with 3.96mm pitch — the board-fit anchor
The 647676-8: Rated 7.5A per contact at 250VAC. The 3.96mm pitch gives each pin enough copper cross-section and air gap to carry that current without exceeding the UL94 V-0 housing temperature rise limit. In a lighting or industrial control panel, this is a solid mid-current power or signal interconnect.
Friction lock and single-wall shroud — vibration resistance without over-engineering
The single-wall shroud guides the plug on one side; the open side leaves room for board-edge component clearance. The 80 µinch thickness is on the high side for tin, which helps resist fretting corrosion in moderate-vibration environments like conveyor controls or HVAC panels.
Active production — no end-of-life watch needed
Sourced through independent distribution.
The friction lock feature requires the receptacle to have the corresponding lock ramp. Confirm the receptacle part number against the TE Economy Power product line — the 3.96mm pitch and single-row layout are standard across the series. Termination is solder to through-hole posts. The contact length on the post side is 0.142" (3.60mm) — enough for a standard 1.6mm PCB with a wave solder fillet.
