12-Position KK254 Receptacle Housing — Free-Hanging Crimp Body
This is standard for modular crimp-to-wire systems — the housing and terminals are line items on separate BOM rows.
Position Count and Pitch — the BOM Match
The housing mates with a 12-circuit KK254 pin header at the same pitch — the header's pin count must match exactly.
Mating and Termination — Crimp-to-Wire Assembly
The free-hanging mount means the housing floats on the wire harness, not on a board; strain relief comes from the wire bundle itself or an external tie-down. The non-gendered contact cavities accept either pin or socket terminals depending on the terminal part number selected — verify the terminal gender against the mating header's contact type.
No official successor or cross-reference has been published; the 0022012121 is the standard 12-position housing in the KK254 range.
