0.80mm Pitch, 80-Position Plug for 8mm Mezzanine Stacks
The TE Connectivity 2-1658045-2 is an 80-position plug from the MICTOR SB series, with a 0.031" (0.80mm) pitch and two rows of outer shroud contacts.
Key Features and Deployment Context
The ground bus (plane) provides a low-inductance return path, which matters for high-speed signal integrity in the MICTOR SB ecosystem.
The 2-1658045-2 mates with a matching MICTOR SB receptacle (typically the 1658045-1 or a similar 80-position female) to achieve the 8mm mated stacking height. The 0.286" (7.26mm) height above board is the plug's own profile; the total stack includes the receptacle's height. Confirm the receptacle part number with the same series and position count for a guaranteed fit.
