The 794223-1: Tin finish suits moderate-cycle applications where cost per circuit is the primary constraint; the contact is rated for the full current capacity of the wire gauge within the housing's temperature rise limits.
Wire gauge selection across the series
Within the Mini-Universal MATE-N-LOK II socket family, the 794223-1 accepts 16-20 AWG, while the 794221-1 covers 18-22 AWG and the 794219-1 handles 22-26 AWG — select the contact by the wire gauge called out on the BOM. The pin counterpart for the same 16-20 AWG range is the 794222-1; all share the same tin plating and crimp termination.
