The TE Connectivity 2331813-2 is an 84-position female edge connector from the Sliver 2.0 series, designed for high-density board-to-board interconnect where signal integrity matters at tight pitches. The 0.024" (0.60 mm) pitch packs 84 contacts into a dual-row readout, which means the board edge pad layout must match that pitch exactly; there is no room for a footprint mismatch at this density.
Board Layout and Assembly Considerations
The dual-row readout with 28 positions per bay on one side and 14 on the other tells you the contact arrangement is asymmetric — the PCB edge pad pattern must match the connector's internal routing, not a simple mirror. The 84-position count is the BOM line match; confirm your circuit count against this number.
