The 280373-1 is an 8-position, single-row header from TE's AMPMODU Mod II series, on 0.100" (2.54mm) pitch. That pitch is the standard for ribbon cable IDC connectors, so if you're wiring to a 0.100" ribbon, the pitch matches — watch pin-one every press. It's a through-hole solder termination, vertical orientation, with a shrouded 3-wall design. The three walls guide the mating receptacle and protect the pins, but the open fourth side leaves room for trace routing or a polarisation key. That current is fine for signal-level loads — think logic-level I/O, sensor inputs, or low-power DC buses — but don't push it for power distribution.
Detent lock and tin plating — vibration and cycle life
It's a practical choice for equipment that sees occasional shock or transport.
