The latch lock fastening provides positive retention under vibration without requiring tools for unmating, which is a practical advantage in field-service or harness-assembly environments where screw-locks slow down the swap. ## Active Lifecycle — No Obsolescence Watch There is no end-of-life notice, no last-time-buy date, and no official successor part number. For procurement planning, this means the housing can be specified into a multi-year build without an obsolescence-driven redesign. ## Mating and Termination — What Fits As a plug housing with female socket contacts, the 178481-1 mates with the matching Universal Power header (male pin header, typically right-angle or vertical through-hole, same 0.156\" pitch and 4-position count). The PA66 housing provides the insulation and strain-relief envelope; the wire gauge range is determined by the terminal barrel size, typically 18-22 AWG for this pitch class.","metaTitle":"TE 178481-1 Universal Power Plug Housing, 4 Pos, 3.96mm","metaDescription":"TE Connectivity 178481-1 Universal Power 4-position single-row plug housing, 0.156\" (3.96mm) pitch, latch lock, -30°C to 105°C.
