From Middle French superseder (“postpone, defer”), from Latin supersedēre, from super (“over”) + sedēre (“to sit”). The meaning “to replace” is from 1642, probably by association with unrelated precede – note that c instead of s (from cēdere (“to yield”), not sedēre (“to sit”)). As a result, supercede is a common misspelling – see therein for further discussion. Doublet of surcease.
