6.00 mm Pitch Sealed Plug Housing for MCP 2.8 Terminals
The TE Connectivity 1-1703818-1 is a 4-circuit plug housing from the Heavy Duty Sealed Connector Series, MCP 2.8 family. It uses a 6.00 mm pitch between contacts and across two rows, giving enough spacing for the 2.8 mm tab terminals these housings are designed around. The housing is sealed, rated for operation from -40°C to 140°C, and mounts to a panel with a slide-on fastening system — typical for engine-bay or outdoor harness runs where moisture and temperature cycling are the main concerns.
The housing accepts MCP 2.8 crimp tab terminals (sold separately), which are terminated to the wire before insertion. The 2-row, 4-position layout means you need four terminals per housing. Order the correct TE MCP 2.8 tab contacts and a compatible crimp tool to complete the assembly.
Sealed Construction and Panel Mount
The housing is marked as sealed, which means the mated assembly with the corresponding receptacle and proper terminal seals (not included in this housing) provides water and dust ingress protection suitable for under-hood or outdoor use. The panel-mount design with a slide-on fastening system allows quick installation into a cutout — no tools needed for the housing itself. The glass-filled PBT insulation material handles the temperature range without warping.
Selection Note vs. 1-1703532-1 (2-Position Single-Row)
The closest functional sibling in the same MCP 2.8 family is the 1-1703532-1, a 2-position single-row plug housing with a 9.50 mm pitch and a locking ramp fastening instead of slide-on. The 1-1703818-1 gives you 4 circuits in a 2-row layout at 6.00 mm pitch — better for higher circuit density in a sealed panel-mount application. The 1-1703532-1 is free-hanging (in-line) and uses a locking ramp; the 1-1703818-1 is panel-mount with slide-on. Choose based on mounting style and circuit count needed.
