The free-hanging (in-line) mounting and crimp termination mean this housing is specified when you want to build a custom cable assembly — terminate individual contacts onto wires, insert them into the housing, and mate to a board-mounted header or another receptacle.
Contacts: Ordered Separately — Pick Your Plating and Wire Gauge
The housing accepts either male or female crimp contacts, so you can use it as a receptacle in a wire-to-board application or as a plug in a wire-to-wire in-line splice. The strain relief feature on the housing helps manage cable pull forces at the back of the contact cavity.
Sourcing and Lifecycle: Still in Active Production
No official cross-reference or direct second-source is on record; the closest parametric peer in the ledger (1-2333134-5) uses a 2.00mm pitch and is not a form-fit-function swap for this 2.54mm-pitch housing.
