Vertical VHDCI Connector P/N 780389-01 Replacement Notice

This change was prompted by a possible quality issue when mating the 780389-01 Vertical VHDCI connector to some National Instrument's VHDCI cables, such as the SHC68-C68-D4 Cable. In some rare instances, there is the possibility that repeatedly mating the Vertical VHDCI connector can damage the internal pins of the VHDCI connector on the NI cable. 

This item is being replaced with part number 785753-01 -- VHDCI Connector, 68-PIN, Vertical, Through Hole Mount. The recommended replacement is functionally equivalent, however, the replacement connector may not be physically compatible with some designs due to slight dimensional and footprint differences. See below for more information on pinout or dimensional differences between the two connectors. NI does not expect that any differences in the signal integrity will be caused by the replacement connector, however as not all use cases have been tested, NI strongly recommends validating the replacement part to evaluate its compatibility with your current designs.
