The 794078-1: Mating pitch is 0.163" (4.14 mm) with an identical row spacing of 0.163" (4.14 mm), giving a 2-row grid that matches the Mini-Universal MATE-N-LOK receptacle family. Tin-lead is a standard finish for cost-sensitive, moderate-cycle applications — it does not offer the cycle life of gold, but the 150 µin thickness provides adequate durability for field-service connectors that are mated a few times per year.
The 794078-1 has a 0.163" (4.14 mm) mating pitch and a 0.163" (4.14 mm) row spacing, with 2 rows and 22 positions total.
