The Molex 764101117 is a 90-position header, male pins, part of the Impact 76410 series — a high-density backplane interconnect system designed for differential-pair routing. It carries 30 differential pairs across 9 rows and 10 columns, with all positions loaded. The right-angle orientation and press-fit termination suit it for board-edge mounting in a backplane, where the compliant pin is pressed into a plated through-hole without solder, giving a reliable gas-tight joint that can be reworked if needed. The connector style is Impact, meaning it uses a modular column architecture that scales in position count and row configuration across the series.
Press-Fit Termination and Board Layout
The press-fit termination eliminates the soldering step — the compliant pin is pressed into the backplane via a staking press, forming a gas-tight connection. Board layout engineers should note the 9-row, 10-column footprint — the routing density is high, and the press-fit hole pattern must match the backplane stack-up. The 30 differential-pair layout implies a specific signal-ground assignment per column; verify the pinout against the system schematic before committing the BOM line.
The alternate MPN 76410-1117 is a functional equivalent — same 90 positions, 9 rows, press-fit termination, gold plating, and UL94 V-0 rating. Use either order code for the same physical part; the difference is the dash-format vs the full 9-digit code.
