The 0.165 inch (4.20 mm) pitch and row spacing demand a board footprint that fits a 4-row pattern with a 13.50 mm insulation height. The 0.220 inch (5.59 mm) mating contact length and 0.210 inch (5.33 mm) post length set the through-hole depth.
The 640505-3 is rated 6 A per circuit at 250 VAC. The tin-plated contacts are suited for moderate current in signal or power distribution applications.
