What This 2-Position Sealed Plug Housing Does
The TE Connectivity 1-1438608-5 is a 2-circuit plug housing from the Micro Quadlok series, designed as a sealed, free-hanging (in-line) interconnect for wire-to-wire harness applications. The black glass-filled nylon (PA) housing carries Connector Position Assurance (CPA) and Terminal Position Assurance (TPA) features, meaning the connector locks audibly when fully mated and each crimp terminal is mechanically confirmed seated before the harness ships.
Sealed, Locked, and Rated for Underhood Temperatures
The housing is listed as sealed, with the CPA and TPA features standard — this is the configuration you want for an engine bay or transmission harness where fluid splash and vibration are constant.
How It Compares to Other TE Sealed 2-Position Plugs
Against the TE 1-1703532-1 — also a 2-position sealed plug, but at 9.50 mm pitch with a locking ramp instead of a latch holder. The 4.00 mm pitch of the 1-1438608-5 saves board space on the mating header footprint, while the 9.50 mm version is sized for higher-current power contacts. Both are free-hanging, crimp-terminated, and active; the choice comes down to current draw and the mating header pitch on the PCB.
