34-Pin Dual-Row SMT Receptacle for Board Stacking
The 10.81 mm stack height is a single fixed dimension, not a range — the board-to-board gap is set by the receptacle and header pair. Verify that the mating header's tail length and the opposite board's component keep-out zone clear this height before committing the layout. Row spacing is also 2.54 mm, so the dual-row header footprint is a simple 2×17 grid at 0.100" centres. The SMT pads need a solder-paste stencil aperture sized for the contact tail width; the board lock apertures are typically oversized to allow the lock to seat without interfering with the pad geometry.
The base product number is 91618, so any future variant (different plating, packaging, or stack height) will share that root. No official successor or cross-reference has been issued for this order code.
