Board-to-Board D-Sub Plug for Dense Signal Interconnects
The 0.050 inch pitch and 0.100 inch row-to-row spacing pack 20 contacts into a compact shell layout, making it a fit for applications that need more circuits than a standard D-sub footprint allows. Gold-plated phosphor bronze contacts with 8.00 µin (0.203 µm) plating handle the signal path, rated at 1 A per circuit and 100 V.
Comparing the 20-Position Plug Against the 8-1437045-3
The 8-1437045-3 is a same-series peer also in Bulk packaging with Active lifecycle status. Both share the 0.050 inch pitch, 2-row layout, and gold contact finish. The decision between them comes down to position count — the 5174215-5 carries 20 positions against the 8-1437045-3's 26 positions. If your BOM calls for 20 circuits, the 5174215-5 is the direct match; the 26-position variant would leave unused pins on a 20-circuit harness.
Mating and Pin Configuration
This is a plug with female sockets, meaning it mates with a D-Type receptacle that has male pins. The 20 positions are arranged in 2 rows, with the shell layout defined by the 0.050 inch pitch x 0.100 inch row-to-row spacing.
