Board-to-Board Header, 50 Positions, 0.100" Pitch
It is a board-to-board interconnect component designed for through-hole soldering to a PCB. The 0.100" (2.54mm) pitch on both rows and between rows matches the standard 0.1-inch grid, making it a direct fit for legacy and current PCB layouts that use this spacing. With all 50 positions loaded, this header provides a full complement of square pins for dense signal or low-power distribution.
The overall contact length of 0.410" (10.41mm) comprises a 0.190" (4.83mm) mating length and a 0.120" (3.05mm) solder tail. The through-hole termination requires a PCB with 0.025" to 0.030" plated-through holes on a 0.100" grid.
Contacts are phosphor bronze with tin plating. The base product number is 79425, and this variant (450) denotes the specific plating and tail length combination.
