Yes and no. Mike plugs come in various sizes depending on the application and equipment to be connected to. A phone-type plug used for a guitar, say, could be used in a "phone" plug jack on anything else.FYI: mic is the abbreviation for "microphone" (only) as is labeled or embossed next to receptacle jacks on some equipments and instruments, but is not the spelling of the commonly spoken, abbreviated reference to a microphone as "mike." So, strictly speaking, we do not speak or write of "mic" or of mic's (of a Mick or of Micks). A guitar cord (plug) plugs into a guitar jack. A microphone, or mike (plug) plugs into PA amplification equipment. Any jack might be labelled, "mic" (for microphone), if it is the intended receptacle for a mikecord plug. In some instances a built in transucer microphone will be labelled as mic. That would be an incorrect usage as a tranducer is not a microphone jack.
