Impact 76165 Backplane Header — 90-Position, 1.35mm Pitch, Press-Fit
The Molex 761655108 is a 90-position header from the Impact 76165 series, arranged in a 9-row by 10-column grid at a 0.053" (1.35mm) pitch. It is a male-pin, right-angle, press-fit connector designed for high-speed differential-pair backplane applications — the contact layout is specified for 30 differential pairs.
Termination is press-fit — the compliant pin cold-deforms into the plated through-hole, creating a gas-tight joint without solder. The through-hole mounting requires the PCB to have the correct finished hole size and plating thickness for the press-fit zone; the board layout engineer should verify the footprint against the Impact 76165 application drawing.
Mating Half and System Compatibility
The 0.053" (1.35mm) pitch and 9-row layout are specific to the Impact backplane system; the mating receptacle must match both the pitch and the column count. No direct pin-compatible alternative exists within the Impact 76165 family at a different position count — the 90-position variant is a fixed BOM line.
