Supersede is the only English word ending in sede. Similar words include four ending in ceed, and several ending in cede (apart from seed). Because of this, supercede is a common misspelling of this word.
From Middle French superseder (“postpone, defer"), from Latin supersedere, from super (“over") + sedere (“to sit"). The meaning “to replace" is from 1642, probably by association with unrelated precede - note that "˜c' instead of "˜s' (from cedere (“to go"), not sedere (“to sit")). As a result, supercede is a common misspelling - see therein for further discussion.
