Product details

10-circuit right-angle header for board-to-cable power and signal

It uses a 3.50mm pitch and 0.181" (4.60mm) row spacing, which sets the PCB footprint and the per-contact current ceiling — current rating varies by wire gauge, but the pitch and contact geometry define the practical limit. A latch holder fastens the mating receptacle securely, making the connection resistant to vibration and cable pull — important for automotive, industrial, and telecommunications environments where the connector sees movement or shock.

Gold-plated contacts rated for repeated mating

The contact base is copper alloy, chosen for conductivity and spring retention.

10 circuits vs 14 circuits in the same series

The closest sibling is the 1723163314, which shares the same 3.50mm pitch, right-angle orientation, gold plating, and latch holder — but carries 14 circuits instead of 10. If your BOM needs more positions without changing the footprint or mating interface, the 14-position variant is a direct swap in the same Ultra-Fit 172316 family.

Frequently asked questions

Does the 1723163310 have a locking latch?

Yes, the 1723163310 uses a latch holder fastening type that locks the mating receptacle in place, providing vibration-resistant retention.

What is the pitch of the Molex 1723163310?

The mating pitch is 0.138" (3.50mm) with a row spacing of 0.181" (4.60mm).

What is the closest functional second-source for the 1723163310?

The 1723163314 is the closest sibling in the same Ultra-Fit 172316 series — it shares the same pitch, orientation, plating, and latch holder but offers 14 circuits instead of 10.
