12-Position Plug Housing — 3.50 mm Pitch, Obsolete
The housing uses a 0.138" (3.50 mm) pitch with a 0.118" (3.00 mm) row spacing, giving enough room for routing 20-24 AWG wire without crowding the cavity walls. The housing is molded from gray polybutylene terephthalate (PBT), a material with good dimensional stability and chemical resistance for industrial environments. This is a common sourcing trap: the housing price covers only the plastic body and the detent lock mechanism.
Obsolete — No Official Successor on Record
For a form, fit, and function cross, the buyer should compare the 0.138" pitch, 12-position count, 2-row layout, and free-hanging mounting style against other TE plug housings in the same pitch class — but no direct drop-in substitute is confirmed.
The 174913-6 mates with a TE header that shares the same 0.138" pitch and 0.118" row spacing — typically a shrouded or unshrouded pin header with 12 positions in a 2-row layout. The detent lock on the housing engages a corresponding ramp or recess on the header for vibration-resistant retention. The PBT housing provides a strain-relief shoulder for the wire exit.
