Datasheet · from renesas.com

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 3), 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.

PartSupplyIoutOscBoards
7660S1.5–12 V10 kHz202

Takes up to 12 V and needs no protection diode; tying pin 1 (boost) to V+ raises the clock from 10 kHz to 35 kHz, out of the audio band.

Fits the same socket

PartSupplyIoutOscBoardsDiffers
TC10441.5–12 V10 kHz289Boost pin to V+ raises the oscillator from 10 kHz to 45 kHz, out of the audio band; 12 V maximum, so not for 18 V doublers.
TC7662B1.5–15 V10 kHz47660 drop-in that takes up to 15 V; tying pin 1 (boost) to V+ raises the clock to 35 kHz.
76601.5–10 V10 kHz15pins 1, 6, 7: NC, LV, OSC. Rated to only 10 V (10.5 V absolute), so a hot 9 V adapter is near its limit; the 10 kHz clock can whine in the audio.
