The socket has no tail — it terminates directly to the board via solder, with the contact body sitting flush against the PCB. ## Board fit and mounting details The socket requires a mounting hole diameter of 0.075 inch and fits board thicknesses from 0.031 to 0.125 inch. Overall length is 0.206 inch, with a flange diameter of 0.093 inch that sits on the top side of the board. Termination is solder — the socket is placed through the plated hole and soldered on the opposite side. The no-tail design means the contact does not extend beyond the board bottom, saving z-height on the secondary side.","metaTitle":"5645518-1 TE Connectivity Series 4 PCB Pin Socket, Tin","metaDescription":"5645518-1 TE Connectivity AMP Connectors Series 4 PCB pin socket.
