Product details

Right-angle board mount for tight z-height

The 1723103306: This is a 6-position, single-row header from the Molex Ultra-Fit 172310 series. The right-angle orientation keeps the mated cable assembly parallel to the PCB — useful when the z-height above the board is constrained by an enclosure lid or a card guide. The 3.50mm pitch sets the board footprint and the per-contact current ceiling — the actual current rating depends on the wire gauge used in the mating half, so pair it with the correct Ultra-Fit receptacle and terminal for the load.

Locking latch and shrouded walls for vibration duty

A latch holder on the shroud locks the mated receptacle in place — this prevents the pair from backing apart under vibration or cable tug. The 4-wall shrouding also protects the male pins from being bent during handling or blind mating.

Gold mating interface for repeated connects

The male pins have 3.00µin gold over nickel on the mating face — a flash plating grade suited for occasional mating cycles in a field-service or test-equipment setting. The solder tails are tin-plated at 60.0µin, which wets well during wave or hand soldering. Rated at 600VAC/DC, this header can handle line-voltage power distribution within the current limits of the chosen wire gauge.

Frequently asked questions

What is the pinout of molex 1723103306?

The 1723103306 is a 6-position single-row header. Pin 1 is typically marked with a triangle or notch on the housing. The pinout follows the standard 1-to-6 sequential layout for a single-row header — no internal connections or keying variations beyond the latch holder. Confirm orientation with the mating receptacle's keying feature.

What is the mating connector for 1723103306?

This header mates with a Molex Ultra-Fit receptacle housing (same 172310 series, 6 circuits, single row) using the matching crimp terminals. The latch holder on the header engages the receptacle's locking ramp. Use the Molex Ultra-Fit female terminal for the chosen wire gauge.
