Substitutes same socket
Parts that fit the same socket: the same function, pin count and pinout. The figures are read off each part's datasheet (this one's from page 4), typical where the sheet gives a typical value, otherwise the maximum. Closest first; the last column says what differs. A different part can change the sound, and a circuit may lean on one particular figure, so read the build document's notes before you swap.
