50-Position Right-Angle Header for Board-to-Board Stacking
At 30µin, the rated mating cycle life is well above the tin-plate baseline; in a production board-stacking application where the header sees maybe a dozen mates over its life, the gold is overkill, but in a test-fixture or field-service board where it gets cycled quarterly, that 30µin buys decades of reliable contact resistance.
Pitch, Current, and Voltage – What the Ratings Mean on the Board
The 0.079" post length (2.00mm) means the solder tail sits flush in a standard 1.6mm board — no need for a deeper plated-through hole.
No pin-compatible direct replacement from Amphenol ICC is listed, so the 10072353-G01-25ULF is the specific order code to match for an existing board layout.
