The 3.81mm pitch is wider than the common 3.50mm or 3.96mm spacing, so it mates only with the matching Dynamic D-3100 header at that pitch. The housing carries a polarizing key to prevent cross-mating with other connectors in the same series, which matters when multiple similar housings share a harness bundle.

Frequently asked questions
Does TE 2-178288-3 include contacts?
No — the 2-178288-3 housing ships without contacts. You must order the female crimp socket terminals separately for the Dynamic D-3100 series.
What is the pitch of 2-178288-3?
The pitch is 0.150" (3.81mm) — wider than the common 3.50mm or 3.96mm spacing, so verify the mating header uses the same pitch.
