VITA 42 XMC Wide Module Connectors

Oct. 12, 2018
Samtec's module connector offers a 12 mm stack height.

A connector set compliant with the revised ANSI/VITA 42.0-2016 XMC Standard, the VITA 42 XMC defines an open standard for supporting high-speed, switched interconnect protocols on an existing, widely deployed form factor.


This revision further defined the concept for the preferred Standard connectors in XMC applications including:

  • Solder ball attachment replaced Paste-On-Pad (POP) for improved solder joints
  • Low Insertion Force (LIF) sockets to ease mating and un-mating
  • Tin-lead alloy available as a solder option
  • Revised ASP catalog numbers
  • 12 mm stack height


Based on these guidelines, the 12 mm stack height options expand the existing family of ANSI/VITA 42 XMC Standard connectors. Chosen for high reliability stemming from the multipoint-of-contact SamArray sockets and robust solder ball design, the updated connector set has been specified for current XMC systems.


In addition to transmitting sensitive high-speed data, these connectors provide power, ground, and auxiliary signals to the mezzanine. The 12 mm mated connector set further optimizes XMC cards for use in wider modules, designed for 1-in. pitch cage systems.
