Product details

20-Position Right-Angle Header for Board-to-Board or Cable

The 178308-3 is a 20-position, dual-row header from TE's Dynamic D-3100 series, designed for board-to-board or cable connections. Its 0.150" (3.81mm) mating pitch and 0.200" (5.08mm) row spacing define the PCB footprint, while the right-angle orientation keeps the mated connector parallel to the board, saving vertical clearance in tight enclosures.

Gold Mating Contacts and Industrial Temperature Range

Mating contacts are gold-plated to 30.0µin (0.76µm) over a copper alloy base, supporting repeated mating cycles in corrosive or field-service environments. The post tails are tin-plated for solderability. Rated for 250V and an operating temperature range of -55°C to 105°C, the header suits general-purpose industrial applications.

Frequently asked questions

What is the pitch of 178308-3?

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

Is 178308-3 a right-angle or straight header?

It is a right-angle through-hole header, meaning the pins exit perpendicular to the PCB mounting plane.

Does 178308-3 have a locking mechanism?

Yes, it features a detent lock for positive retention against vibration.
