Displayed contact count

Mating height and floating range are not stated on the drawing, so mating is not shown. Positions 20, 30, 40, 50 are built from the factory STEP of another pin count by repeating the pitch cell; lengths follow the dimension table. On 20, 30, 40, 50 the centre pick-up area / housing detail is approximate.

PRODUCT OVERVIEW

About this model.

CBB170-XXXXX-XX is a floating board-to-board connector listed in the factory product catalog. Its recorded selection points include 0.4 mm pitch, 20, 30, 40, 50, 60 contacts. The part number should be checked against the board or cable interface before any footprint is released.

The termination method should be confirmed for this exact order code. It names CBB169 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 CBB170-XXXXX-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.
