You have several options: us a mystery part or a generic 6 pin IC to get the apparent 6 connections you need (I’m assuming you only want breadboard to show the module interconnection not pcb) of provide a pointer to a data sheet for the esc you want (as there doesn’t appear to be a standard one in a quick look at the ardupilot mega site) which board dimensions so that someone could make a part to match it.
