50-Position, 2.00mm Pitch, Right-Angle Header — Board-to-Board Fit
The 98423-G61-25LF: Rated at 2A per contact and 200V AC/DC, this header suits low-power signal or control applications where the per-contact current stays well below the 2A ceiling.
Right-Angle Orientation and Board Layout
The insulation height of 0.157" (4.00mm) plus the mating contact length of 0.157" (4.00mm) defines the mated stack height — the receptacle's mating face sits approximately 8mm above the board surface. For a 50-position dual-row header, the board footprint spans roughly 50 × 2.00mm = 100mm along the row, plus the keep-out for the through-hole tails. The right-angle body keeps the connector within the board edge, useful for mezzanine or parallel-board stacking where the header sits at the board perimeter.
Plating and Contact Durability
The mating finish is 30.0µin gold over GXT™ (a palladium-nickel alloy underplate) — this is a robust contact interface for applications needing 500+ mating cycles. The gold resists oxidation in humid or mildly corrosive environments; the GXT underlayer prevents nickel diffusion through the gold.
