Product details

Board-to-Board Receptacle for Mezzanine and Parallel-Stack Designs

Dual-Row Layout and Through-Hole Termination

In high-vibration environments, a header with a positive locking feature is recommended.

Comparing the 18-Position Receptacle to Its 10-Position Sibling

Within the Dubox™ series, the 68683-309LF (18 positions) is the higher-density choice compared to the 10-position variant (68683-103LF). For a BOM that needs fewer I/O, the 10-position part saves board space; for more signals, the 18-position part avoids a second connector.
