The TE Connectivity 53884-4 is a 1-position Power Lock Series II housing — a free-hanging, inline splice shell that mates with an identical counterpart. The self-mating design means two of these housings, each loaded with a crimp terminal, snap together to form a wire-to-wire connection. The locking ramp on each half engages when mated, holding the pair together against vibration and cable tug. This is a single-wire splice housing, not a multi-circuit connector: one position, one wire per side.
Contacts Are Ordered Separately — Here Is What Fits
It accepts non-gendered crimp terminals that are also ordered separately under the 53884 base product number family. The crimp termination style means the wire is attached to the contact before it is inserted into the housing. For the exact contact part number and wire gauge range, reference the TE Connectivity Power Lock Series II application tooling drawing — the base number 53884 is the starting point for the contact search.
There is no official second-source or cross-reference on file; the 1-1703532-1 is a different series (sealed, 2-position, black PBT housing) and is not a functional replacement.
