D-Sub Receptacle for the DA Shell Footprint
It uses the standard DA shell size (2-row, 15-pin layout), so the board footprint and mating hardware are the same as any other DA-15 D-sub.
What the 1.5A Rating and Gold Plating Mean for the Fit
At 1.5A per contact, this is a signal-level D-sub. If the application needs higher current per contact, the same footprint is available with different contact variants, but the 2301840-1 is specced for signal duty.
Board Locks and Screwlock Hardware
The flange features a female 4-40 screwlock on the mating side, which is the standard locking mechanism for the DA shell size.
Comparing Packaging Options: Tray vs Box vs Bulk
The 2301840-1 ships in a tray. Two functional peers — 3-1393480-8 (box packaging) and 8-1437045-3 (bulk packaging) — carry the same electrical and mechanical specs. The choice is purely a packaging preference: trays for automated pick-and-place lines, box for volume orders, bulk for small-quantity prototype or repair work. All three are active and ROHS3 compliant.
