Product details

12-position, 2.50mm-pitch right-angle header for harness-to-board

A mounting flange on the housing adds extra mechanical hold to the PCB. Rated for automotive and general-purpose use, the connector operates from -30°C to 105°C.

Pitch, position count, and mounting orientation

At 2.50mm pitch, the 175974-2 sits between finer-pitch board-to-board connectors and the wider 2.54mm (0.100") standard. The 12 positions are arranged in two rows with a row spacing of 0.205" (5.20mm), giving a compact but routable footprint. Compared to the single-row, 3-position 1-2232960-3 from the same series, this header offers four times the circuit count in a dual-row layout.

We source this part per RFQ against your BOM quantity.

Frequently asked questions

What is the pitch of 175974-2?

The pitch is 0.098" (2.50mm) on the mating interface, with a row spacing of 0.205" (5.20mm).

Is 175974-2 through hole and right angle?

Yes, it is a through-hole, right-angle header.

Does 175974-2 have a mounting flange?

Yes, the housing includes a mounting flange for additional mechanical retention on the PCB, which helps in vibration-prone environments.

What is the current rating of 175974-2?

The current rating varies by wire gauge used in the harness. The header itself does not have a fixed ampacity — the limiting factor is the wire size and temperature rise in the application.
