Through-hole mounting, shrouded with friction lock
The 5-1123723-0 is the 10-position member of TE's Economy Power header line, a single-row shrouded board-to-cable/wire connector with friction-lock retention.
Flammability and housing materials
The 3.00 mm insulation height and 0.146" post length are fixed across the series — the footprint and keying are shared, so the 10-position board layout carries over to other circuit counts in the Economy Power family.
