40-Position Dual-Row at 2.00mm Pitch
The 9-1734516-0: This is a 40-position, dual-row board-to-board receptacle from the AMPMODU series, pitched at 2.00mm between contacts and rows. The 2.00mm pitch sets the board footprint density — it's a common signal-level spacing that balances routing channel width against PCB real estate. With all 40 positions loaded, this receptacle mates with a matching 2.00mm pitch header to form a mezzanine or coplanar board stack.
