0.025" Pitch, 38-Position MICTOR Receptacle
The TE MICTOR 5767114-1 is a 38-position receptacle with center strip contacts, built on the 0.025" (0.64mm) pitch that defines the MICTOR series. This is the fine-pitch differential-pair interconnect TE designed for high-speed board-to-board applications where signal integrity matters more than brute current capacity. The 2-row layout packs 38 positions into a compact footprint that forces careful routing — the 0.025" pitch leaves no room for hand-soldering or rework without a microscope. Surface-mount termination means this receptacle feeds into a reflow line, not a wave solder bath. The board guide and ground bus plane are not optional extras — the guide protects the fine-pitch contacts during blind-mate assembly, and the ground bus gives return current a low-inductance path that keeps the signal edges clean. Without the ground plane stitched to the PCB, the impedance breaks down and the rise times degrade. This is the plating grade you want when the board stack is tested, unstacked, and re-mated during system bring-up, not a one-time production mate.
Stacking Height Coverage — One Receptacle, Eight Heights
What sets this receptacle apart from a fixed-height mezzanine connector is the mated stacking height range: 6.6mm, 9mm, 10.92mm, 12.57mm, 17.96mm, 18.75mm, 20mm, and 22.86mm. The same 5767114-1 board footprint works across all eight heights by swapping the mating plug. That means one PCB layout covers multiple card-to-card gaps — useful when the same backplane design must accommodate different daughtercard thicknesses or component keep-outs. The 6.6mm height is the tightest stack, common in mezzanine applications where the board spacing is driven by the tallest component on the underside. The 22.86mm height opens up room for heatsinks or through-hole components on the mating board. The receptacle itself sits 0.236" (6.00mm) above the board, so the plug determines the rest of the gap.
It is ROHS3 compliant. No official replacement or cross-reference has been published, so the BOM line stays with this order code.
