What This 8-Position Plug Housing Is
The Molex 5023800800 is an 8-circuit plug housing from the CLIK-Mate 502380 series, a 1.25 mm pitch wire-to-board interconnect family. It is a free-hanging (in-line) housing with a single row of cavities, designed to accept crimp terminals that are ordered separately — contacts are not included with this housing. The natural colour PET (polyethylene terephthalate) insulator carries a latch lock for positive retention when mated to the corresponding header. The housing is ROHS3 compliant.
Wiring and Termination
Termination is crimp-style: you select the correct Molex CLIK-Mate crimp terminal for your wire gauge (typically 26-30 AWG for this series, though the exact gauge range should be confirmed from the terminal datasheet), insert it into the housing cavity until the latch clicks, and pull a retention check. The single-row layout keeps the wiring bundle narrow — useful for space-constrained harness runs.
Mating Half and Fit
This plug housing mates with the corresponding Molex CLIK-Mate 1.25 mm pitch wire-to-board header (e.g., the 502382 series right-angle or vertical headers, 8 positions). The latch lock on the housing hooks onto the header's locking tab. Because the pitch is 1.25 mm, the board footprint is compact — about 10 mm wide for the 8-position header. Confirm the header's mounting style (SMT or through-hole) and stack height to match your board-to-wire clearance budget.
