ECIA EIA-616-A

This standard is applicable to modular two-part connectors forprinted wiring boards associated with equipment fortelecommunication or electronic devices using similar techniques.The standard covers high-density connectors providing modularcontact arrangements with signal contacts, power contacts, andoptions for special contacts (high current/coaxial/optical). Bothfixed and free board mounted connectors have module sizes inmultiples of 12 mm. Both are end-to-end stackable without loss ofcontact positions.

The objectives of this standard are to establish:

• dimensions of connectors for a metric equipment practice;the dimensions for height, width, and depth are based on a multiplegrid of 0,5 mm in accordance with IEC Publication 60917-1;

• type designation;

• common features;

• dimensions;

• test program

General data

This standard defines modular two-part connectors, with assessedquality, for free and fixed boards. The connectors are based on amultiple grid of 0,5 mm, and configured with contacts spaced with a2,0 mm pitch. The connectors are available as stackable modules andmultimodules with n x 12 mm lengths and in 4 or more rowconfigurations, with coding and optional special contacts:

– Performance levels: 1, 2, and 3

– Assessment levels: A and G

– Combination of performance levels and assessment levels: 1A,2A, 2G, and 3A

Recommended method of mounting

A complete onnector consists of one or more connector modules ormultimodules that are mounted stackable to each other, without lossof contact positions. Free board connector modules are mounted onthe edge of the board and have female contacts with right-anglesolder or press-in terminations.

Fixed board connector modules are mounted on the backplane andhave male contacts with straight solder or press-in terminations.They have optional solderless wrap or rear plug-uppossibilities.

Information on the availability of components qualified to thisstandard is given in the qualified product list.

Minimum and maximum number of contact cavities

The connector modules and multimodules provide four or morerows. Cavities for signal contacts can be fully or partiallyloaded. Cavities with power contacts are normally fully loaded.

The connector modules featuring cavities for special contactsare single-row, that can be individually loaded.
