Product details

13-position SMT right-angle header at 1.25 mm pitch

Solder retention and shrouded housing for vibration resistance

A full 4-wall shroud surrounds the pins, protecting them during handling and guiding the mating receptacle into alignment — the insulation height is 0.136" (3.46 mm), so the shroud clears most low-profile cable plugs.

Frequently asked questions

What is the mating connector for 1-1734261-3?

This is a Board to Cable/Wire header — it mates with a receptacle housing that accepts 1.25 mm pitch crimp terminals. The mating half is part of the same HPI series; confirm the circuit count and keying match your cable assembly.

What is the closest functional second-source to 1-1734261-3?

The peer 1-2232960-3 is a different pitch (2.50 mm) and through-hole mounting, so it is not a direct footprint swap. No exact second-source is listed — this part is a single-vendor TE product within the HPI series.
