Board-to-Board Mezzanine Interconnect, One Part Number
The TE Connectivity 2199070-4 is a 24-position member of the Fine Pitch Hermaphroditic (FPH) series — a self-mating, non-gendered connector that serves as both plug and receptacle. At 0.020" (0.50 mm) pitch in a 2-row layout, it targets dense board-to-board mezzanine stacking where every millimeter of PCB real estate counts. The hermaphroditic design means you stock one part number for both halves of the interconnect, simplifying BOM management and reducing inventory line items.
Board Layout Fit: Pitch, Stack Height, and Footprint
The 0.50 mm pitch demands a controlled SMD placement process — the pad width and spacing on the PCB must match the connector's footprint exactly to avoid solder bridging. Surface-mount termination eliminates through-hole soldering and allows reflow assembly on both boards simultaneously. The 2-row, 24-position layout gives 12 contacts per row, which aligns with common 12-bit or 24-bit parallel data buses in embedded systems.
