12-Position, Dual-Row, 2.54 mm Pitch — AMPMODU Mod IV Receptacle Housing
The 87631-8: It is a free-hanging (in-line) crimp housing — no contacts are included, so you order the female socket terminals separately. The black glass-filled nylon body carries a detent lock for positive retention when mated to the corresponding header. This is the housing half of a wire-to-board or wire-to-wire interconnect system for internal harnesses where the 2.54 mm grid keeps board routing clean and the crimp termination allows field-serviceable repairs.
Both the pitch and the row spacing are exactly 0.100" (2.54 mm). If your board layout or mating header uses a different pitch or row spacing, this housing will not align — check the header's datasheet for the same 2.54 mm grid before committing the BOM line.
Contacts Not Included — Plan the Terminal Order
The listing explicitly states Contacts Not Included. This housing accepts AMPMODU Mod IV female socket crimp terminals — you need to source those separately. The crimp termination means you attach the terminal to the wire with a crimp tool, then insert it into the housing until the detent lock clicks. If you are building a harness, order both the housing and the terminals at the same time to avoid a line-down situation.
