Product details

Right-angle 6-position header for board-edge wiring

The 178303-3 is a 6-position, 3.81mm pitch header from TE's Dynamic D-3100 series, designed for board-to-board or cable connections.

Gold contacts rated for industrial duty

The post tails are tin-plated for reliable solder wetting. Compared to the sibling 1-1871673-2 (2.50mm pitch, tin mating finish, 4 positions), the 178303-3 offers wider pitch and gold contacts — a better choice if your board has the space and you need higher mating-cycle reliability.

Frequently asked questions

What is the pitch of the TE 178303-3 header?

The mating pitch is 0.150" (3.81mm), with a row spacing of 0.200" (5.08mm).

What is the mating connector for the 178303-3?

This is a header with tab contacts. It mates with a Dynamic D-3100 series receptacle housing that accepts the matching crimp terminals. The specific receptacle order code depends on your wire gauge and circuit count — consult the series product drawing for the correct mating half.
