Product details

4-position right-angle header for wire-to-board power

The shrouded 4-wall housing with latch holder provides positive retention against vibration-induced disconnect — no secondary lock required.

Voltage, temperature, and flammability envelope

Rated 600 VAC/DC, the header covers industrial control and appliance power distribution within the insulation class of the LCP housing. Glow wire compliant per the features list, which is relevant for appliance and white-goods applications where the connector must withstand a 850°C glow-wire test without igniting.

No official direct replacement or cross-reference from Molex is recorded. If you are consolidating SKUs, the Ultra-Fit series includes multiple position counts and plating options that share the same 3.50 mm pitch and latch holder interface — one family, fewer SKUs.

Frequently asked questions

What is the mating connector for the 1723104104 header?

This header mates with a matching Ultra-Fit receptacle housing that accepts crimp terminals. The latch holder on the header engages with the corresponding latch on the receptacle for a vibration-resistant mate. Confirm the receptacle part number from the same 172310 series for the correct circuit count and wire gauge.
