Connector identity and board-fit
The 0.050" (1.27mm) pitch on the mating interface and 0.100" (2.54mm) row spacing define the PCB land pattern and the minimum board real estate needed for routing all 50 circuits. The square female socket contacts are phosphor bronze with 30.0 µin (0.76µm) gold on the mating surface and 150.0 µin (3.81µm) tin on the solder post — the gold layer supports repeated mating cycles without exposing the base metal, while the tin post wets reliably during reflow.
Mated stack height and mechanical envelope
The insulation height of 0.370" (9.40mm) and the listed mated stacking heights of 11.94mm and 13.08mm give two possible board-to-board spacing options depending on the mating header used.
No official direct replacement or cross-reference on record — the base product number 104550 covers the family, so verify the exact position count and plating before substituting.
