Product details

The 178216-3 is a 12-position, 4-row header from TE's Dynamic D-3400 series, on a 0.150" (3.81mm) mating pitch with 0.200" (5.08mm) row spacing. It mates with Dynamic D-3400 series receptacles (crimp or IDC) that share the same 4-row, 12-position layout. The shrouded - 4 wall housing guides the mating connector into alignment and protects the gold-plated tabs during handling.

Board lock and termination details

Termination is solder only — no press-fit option in this order code.

How the 178216-3 compares to the 1-1871673-2

The 178216-3 offers 12 positions, 4 rows, a wider 0.150" pitch, and gold mating finish — a different density and contact reliability class.
