The Amphenol 10159583-C231000LF is a 40-position plug from the Minitek® MezzSelect™, Basics+ series, configured as a blade power connector with a hybrid contact layout: 24 signal positions and 16 power positions. This is not a uniform pin field — it is a mixed-power interconnect designed to carry both logic-level signals and DC rail current through the same housing. The 0.079" (2.00mm) pitch keeps the board footprint compact for the 8-row density, while the through-hole solder tails handle the mechanical retention a 40-position connector demands.
The 24 signal, 16 power contact layout means this plug is keyed for specific current paths — the power blades are physically larger than the signal pins, so the PCB footprint must match the assigned positions. If your application requires high-cycle durability, the flash grade is the limiting factor, not the contact material.
Mating half and board layout fit
This plug mates with the 10159578-C231000LF receptacle, which mirrors the same 40-position, 8-row, 2.00mm pitch layout with 24 signal and 16 power positions. The 8-row density at 2.00mm pitch means the board keep-out zone is tall — plan for a rectangular footprint that accommodates the full array, and use the board guide to take the shear load during mating. Compared to the older PwrBlade+ 10106262-7006001LF (2.54mm pitch, 4 rows, right-angle), this Minitek MezzSelect part is a denser, straight-through stack option for mezzanine spacing rather than a board-edge power tap.
