90-Position Impact Header — Guide Right, Press-Fit
The TE Connectivity 2007781-2 is a 90-position Impact series header with male pins, arranged in a 9-row by 10-column grid. It uses the Guide Right connector style, which means the housing includes a keying feature that orients the mating pair and prevents misalignment during blind-mate assembly in a backplane chassis. The 0.075" (1.91 mm) pitch is the Impact standard for high-density differential-pair routing — each column carries the signal pairs and ground shields typical of 25 Gbps+ backplane designs. Termination is press-fit, which eliminates the need for soldering and allows the connector to be pressed into plated through-holes on the backplane. This is the preferred termination for high-reliability, high-layer-count boards where rework of a soldered connector would risk damaging the board.
That thickness is well into the high-cycle range — suitable for the repeated mating and unmating a backplane connector sees during system integration and field service.
