About this model.
CBB189-XXSXX-XX is a board-to-board connector listed in the factory product catalog. Its recorded selection points include 0.35 mm pitch. 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. The matching half and ordering suffix still need confirmation from a controlled drawing. 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 CBB189-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.
