About this model.
CBB191-XXSXX-XX is a board-to-board connector listed in the factory product catalog. Its recorded selection points include 0.35 mm pitch, 30, 38, 40, 50, 60 pins contacts, 0.75 mm mated height. The part number should be checked against the board or cable interface before any footprint is released.
The catalog lists SMT as the termination method. It names CBB190 as a mating part or series; engineering should confirm the precise counterpart and assembly height. Consider contact assignment, insertion direction, tooling access and the total tolerance stack in the completed product.
Use the specifications and drawings below as a traceable starting point for CBB191-XXSXX-XX. Values shown for a series are not a substitute for a released variant drawing. Request the latest datasheet, confirm any pending fields with engineering and validate the complete assembly under your own project conditions before production design-in.
