This is a panel-mount shell with a mounting flange and a slide-on fastening system, designed to lock into a matching receptacle on the other side of an enclosure wall or bulkhead. ## What the Sealed Flange Means for the Build The mounting flange and sealed construction tell you this housing is meant for a panel feed-through — it bolts to the enclosure wall, and the seal keeps washdown or road spray out of the cabinet. The slide-on mate cycles quickly in assembly, but the locking relies on the receptacle side having the matching ramp or latch. For the wiring side, this is a crimp-termination housing: you insert the MCP 1.5K tab contacts (sold separately — the housing ships empty) and the terminal position assurance (TPA) in the mating receptacle confirms full seat. ROHS3 compliance is confirmed. This is a single-source TE part; there is no official second-source cross-reference in the series.","metaTitle":"TE 1-1703843-1 MCP 1.5K Plug Housing, 3 Pos, 4mm","metaDescription":"TE Connectivity 1-1703843-1 MCP 1.5K plug housing, 3 positions, 4.00mm pitch, panel mount with flange, sealed.
