Single-row, 9-position header at 0.100-inch pitch
The 147278-8: It is a surface-mount, right-angle part—the pins exit perpendicular to the PCB plane, which suits tight board-to-cable or board-to-board layouts where the mating connector approaches from the side. Board locks and solder retention features keep the part anchored during reflow and in service.
The tin-lead post finish (100.0 µinch) is the solder-tail side, not the mating interface.
As a shrouded header with latch holder, it mates with AMPMODU MTE receptacle housings that accept the corresponding crimp contacts. The 0.100-inch pitch and single-row 9-position layout are common across many TE MTE cable assemblies and board-mount receptacles—confirm the mating half part number against your assembly drawing.
