100-position right-angle header for dense board-to-cable interconnects
The 5-104477-7: This AMPMODU System 50 header packs 100 positions into a 1.27mm pitch, giving you a high-density interconnect for board-to-board or board-to-cable applications where real estate is tight.
Pitch, footprint, and stack-up for board layout
At 0.050-inch (1.27mm) pitch with 0.100-inch (2.54mm) row spacing, this header demands a fine-pitch PCB layout — expect 4-layer boards for fan-out on the inner rows. The 0.145-inch (3.68mm) post length gives enough stand-off for through-hole soldering on standard 1.6mm boards.
Mating half and build-to-print BOM
This header mates with AMPMODU System 50 receptacles (e.g., 104478 series) that accept 0.050-inch pitch ribbon cable or discrete crimp contacts. The 2-wall shrouding guides the mating plug and protects the pins during handling. For a complete assembly, you will need the receptacle, contacts, and any backshell — all sold separately.
