The 1-178313-2: Single-row, 3-position header on 3.81mm pitch — the footprint is defined by the 0.150" post length and the through-hole pattern. The 4-wall shrouding protects the tab contacts during blind mating and guides the matching receptacle into alignment. Mates with TE Dynamic D-3100 series receptacle housings (e.g., 1-178128-3 or similar 3-position crimp housings) that accept the matching tab terminals. The detent lock provides audible feedback on full engagement — no secondary lock required for moderate-vibration industrial environments.
The tin-plated solder tail (contact finish - post) is compatible with standard wave-solder profiles and does not require a gold-to-tin interface at the board joint.
Board Lock and Mechanical Retention
In a single-row header with only three positions, the board lock is the primary retention feature — without it, the solder joints alone carry the full cable strain.
Thermal and Flammability Rating
The 105°C ceiling covers most industrial cabinet and general-purpose equipment inside an enclosure.
