MICTOR 38-Position Receptacle — High-Density Mezzanine Interconnect
The TE Connectivity MICTOR 5767061-1 is a 38-position receptacle with center strip contacts, designed for high-density board-to-board mezzanine stacking. The dual-row arrangement with palladium-nickel contacts (30.0µin gold flash) is specified for repeated mating cycles in backplane and midplane applications where signal integrity and mechanical durability are both on the line. This is not a general-purpose header — it is a precision interconnect for systems where the signal layer count and board stack-up are already locked in.
Stacking Heights and Board Fit
The 5767061-1 supports eight mated stacking heights: 6.6mm, 9mm, 10.92mm, 12.57mm, 17.96mm, 18.75mm, 20mm, and 22.86mm. That range covers everything from tight mezzanine card spacing to taller daughtercard offsets. The 0.236" (6.00mm) height above board means the receptacle sits low on the PCB, leaving the mating plug to carry the stack-up tolerance. Surface-mount termination keeps the assembly reflow-compatible, though the fine pitch demands a solder paste stencil designed for 0.64mm pad spacing.
The palladium-nickel underlayer resists fretting corrosion better than nickel alone, and the gold flash keeps contact resistance low through the first several hundred cycles. This is the right finish for a backplane connector that sees periodic card swaps — not for a one-time harness install.
No last-time-buy or phase-out notice. The base product number 5767061 covers the family; this variant is the 38-position, tube-packaged version.
