The 5499141-8 is a board-to-cable/wire header from the AMP-Latch series, designed to mate with standard AMP-Latch IDC sockets for parallel or ribbon-cable interconnect. Its 0.100" pitch and 2-row layout match the footprint of industry-standard 34-conductor IDC cable assemblies. Latch lock/eject hooks (long) hold the mated pair securely against vibration and provide a lever for unmating when the connector sits in a dense array.
34 positions, all loaded, arranged in two rows spaced 0.100" apart. The post length for solder is 0.110" (2.79 mm) — sufficient for standard 0.062" PCBs with through-hole wave solder.
This is a signal-level header — not for power distribution.
Mating surface is gold or gold-palladium, 30 µinch (0.76 µm) thick over nickel. The post finish is tin, 100 µinch (2.54 µm) thick — adequate for solder joint reliability and corrosion resistance on the board side.
Keying, flange, and mis-mate protection
The slot prevents inserting the wrong socket (e.g., a 40-position socket into a 34-position header), and the flange lets you bolt the header to the board for extra mechanical retention against cable pull.
