The 63453-140LF: Each contact is rated 2 A; at 40 circuits that is 80 A total across the connector, but the practical limit is set by the number of adjacent contacts carrying full current simultaneously.

RoHS compliant.
Board-to-Board Fit — What It Connects To
Insulation height is 0.177" (4.50 mm) — account for that in the mezzanine stack-up when calculating the total z-height budget.
If 40 positions are not the BOM target, the 63453 series offers identical pitch, plating, and current rating in 34-position (63453-134LF), 44-position (63453-144LF), and 48-position (63453-148LF) variants — all through-hole, all gold mating finish.
