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 12), 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.

Fits the same socket

Part	Input	Supply	GBW	Slew	Noise	Iq	Boards	Differs
LMC660CN	CMOS, RR out	4.75–15.5 V	1.4 MHz	1.1 V/µs	22 nV	0.4 mA	4	CMOS quad limited to 15.5 V total; rail-to-rail output and an input range that includes ground.
JRC2902	bipolar	3–32 V	0.5 MHz	0.5 V/µs		0.25 mA	2	bipolar input. LM324-class single-supply quad with crossover distortion; the DIP14 (NJM2902N) is listed as discontinued.
LM348	bipolar	8–36 V	1 MHz	0.5 V/µs		0.6 mA	2	bipolar input; draws 0.6 mA per amplifier. Four 741-class amplifiers in the LM324/TL074 pinout.
3403	bipolar	5–30 V	1 MHz	0.6 V/µs		0.7 mA	17	bipolar input; draws 0.7 mA per amplifier. 741-class quad that runs from a single supply; the input range includes the negative rail and the output has a class AB stage.
LM324	bipolar	3–30 V	1.2 MHz	0.5 V/µs	35 nV	0.35 mA	100	bipolar input. Input range includes the negative rail and the output nears ground, but it is slow and shows crossover distortion.
LF444	JFET	?–36 V	1 MHz	1 V/µs	35 nV	0.15 mA	4	JFET input. Low-power JFET quad at about 150 µA per amplifier.
TLC2274	CMOS, RR out	4.4–16 V	2.25 MHz	3.6 V/µs	9 nV	1.2 mA	1	draws 1.2 mA per amplifier. CMOS rail-to-rail-output quad limited to 16 V total.
TLC27M4AIN	CMOS	3–16 V	1.1 MHz	4.5 V/µs	32 nV	0.06 mA	8	Low-power CMOS quad limited to 16 V; the input range includes the negative rail (single-supply friendly).
TL064	JFET	10–30 V	1 MHz	3.5 V/µs	30 nV	0.2 mA	17	JFET input; rated from 10 V. Low-power JFET quad at 200 µA per amplifier.
TL974	RR out	2.7–12 V	10.6 MHz			2.48 mA	1	draws 2.48 mA per amplifier; much faster, may oscillate in a slow part's place. Low-noise quad (4.4 nV/√Hz at 100 kHz) limited to 12 V total; it will not survive an 18 V rail.
