The 2.00 mm pitch keeps the board footprint compact while leaving enough room between contacts for reliable insulation displacement with 20-24 AWG wire.
Mating Half and Terminal Fit
This receptacle mates with a 2.00 mm pitch male header — the TE CT series header with 0.64 mm square pins. The crimp terminal that fits this housing is a female socket for 20-24 AWG wire, typically gold or tin plated depending on the mating cycle requirement. The free-hanging design lets you route the harness directly to the header without a board-mount lock; the housing relies on the terminal retention lances and the housing's internal ramp to keep the contact seated. No secondary TPA (terminal position assurance) is listed for this series, so verify the terminal is fully inserted until the lance clicks.
The 1-179228-5 is a 15-position single-row housing. The closest sibling in the CT series is the 1-179228-4, which is the 14-position version at the same 2.00 mm pitch — the only difference is the cavity count, so the board header and crimp terminals are otherwise identical. If the BOM calls for 15 circuits, this is the match; the 14-position housing leaves one circuit unpopulated. The 1-2333134-5 is a 30-position dual-row CT receptacle at the same 2.00 mm pitch but with a locking ramp — that part doubles the density and adds a positive latch, which changes the mating envelope entirely.
