Product details

Right-angle shrouded header for board-edge power and signal

Pitch is 3.50 mm on the mating interface, with a row spacing of 4.60 mm — wider than a typical 2.54 mm header, which gives more room for trace routing between pads and supports higher current per circuit when paired with the appropriate wire gauge.

Gold mating finish and current rating tied to wire gauge

For a given application, match the wire gauge to the load current and consult the terminal's derating curve.

Mating and board placement notes

The 4-wall shroud also protects the pins from accidental contact before mating.

Frequently asked questions

What is the mating connector for 1723163212?

The 1723163212 mates with the Ultra-Fit 172316 series receptacle housings. These are sold separately and accept the matching crimp terminals. The latch holder on the header locks with the receptacle's ramp for vibration-resistant retention.

What is the pitch of Molex 1723163212?

The mating pitch is 0.138" (3.50 mm) with a row spacing of 0.181" (4.60 mm). The 3.50 mm pitch is wider than many standard headers, providing more PCB routing space between pads and supporting higher current per circuit when paired with the correct wire gauge.
