The Amphenol 10162581-3134131LF is a 31-position receptacle from the Conan™ Lite series within the MezzSelect™ family. It is a surface-mount, dual-row, outer-shroud-contact connector designed for board-to-board mezzanine stacking. The 1.00mm pitch and 3.28mm height above board place it in the fine-pitch, low-profile mezzanine class, typically used in compact electronics where PCB real estate is tight and a parallel board stack is required. The outer shroud design protects the contacts during handling and alignment, and the built-in board guide assists with automated pick-and-place assembly.
Stack Height Flexibility and Board Fit
A key feature of this receptacle is its compatibility with multiple mated stacking heights: 4.15mm, 4.5mm, 5mm, 6mm, and 7mm. This range gives the board designer flexibility to choose the spacing between parallel PCBs without changing the receptacle footprint. The actual stack height is determined by the mating header selected from the same Conan Lite series. The 1.00mm pitch and dual-row layout with 31 positions yield a compact footprint. The pick-and-place feature and board guide are standard for high-volume SMT assembly lines, reducing placement errors during reflow.
This 31-position receptacle shares the same 1.00mm pitch, 3.28mm height above board, and dual-row layout with the 21-position (10162581-3134121LF), 25-position (10162581-3134125LF), and 41-position (10162581-3134141LF) members of the Conan Lite series. If your BOM calls for 31 signal lines, this is the direct match; the 25- or 41-position variants serve lower or higher density needs on the same basic footprint.
