Board Layout and Fit
With a single row of 9 pins on 0.100" centers, the board footprint is narrow — about 0.900" long plus the keep-out for the 0.100" (2.54mm) insulation height. The through-hole solder tails extend 0.165" (4.19mm) below the board surface, which is standard for 0.062" thick PCBs with plated through-holes. The overall contact length of 0.525" (13.34mm) and a mating pin length of 0.260" (6.60mm) give enough reach for stacking with a standard receptacle without bottoming out.
There is no official replacement or cross-reference on record; the 9-position single-row configuration is the exact fit for the circuit count specified.
