Contact Construction and Plating
The 3-5331677-4: The knockout bottom feature indicates a stamped contact with a breakaway tab, typical for automated assembly where the contact is inserted into a housing and the tab is sheared off.
Mating and Dimensional Fit
Accepts pin diameters from 0.030" to 0.033" (0.76mm to 0.84mm) — the socket depth of 0.125" (3.18mm) ensures full pin insertion and contact wipe for reliable electrical connection. Overall length is 0.138" (3.51mm) with a flange diameter of 0.080" (2.03mm), and the mounting hole diameter range is 0.062" to 0.063" (1.57mm to 1.60mm) for press-fit into the housing cavity.
Temperature Range and Termination
Rated for -65°C to 126°C operating temperature — the beryllium copper spring properties are maintained across this range, making it suitable for aerospace and industrial thermal cycling. Termination is solder, with no tail — the contact is designed for solder-cup or through-hole solder attachment to a wire or PCB pad.
Supplied in bulk packaging — no reel or tape-and-reel option listed, so hand-loading or tube feed is expected on the assembly line.
