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.

Fits the same socket

Part	Input	Supply	GBW	Slew	Noise	Iq	Boards	Differs
2904	bipolar	3–32 V	0.6 MHz	0.5 V/µs		0.35 mA	5	input range reaches the negative rail. LM358-class single-supply dual; the DIP8 (NJM2904D) is listed as discontinued.
TL022	bipolar	10–30 V	0.5 MHz	0.5 V/µs	50 nV	0.065 mA	90	Micropower dual at about 65 µA per amplifier; slow (0.5 MHz, 0.5 V/µs).
LM358	bipolar	3–30 V	0.7 MHz	0.3 V/µs	40 nV	0.5 mA	86	input range reaches the negative rail. Input range includes the negative rail, but it is slow and its class-B output shows crossover distortion.
LM258P	bipolar	3–30 V	0.7 MHz	0.3 V/µs	40 nV	0.5 mA	3	input range reaches the negative rail. Extended-temperature LM358; same behavior, input range includes the negative rail.
4559	bipolar	?–36 V	4 MHz	2 V/µs		1.65 mA	29	Audio dual with stronger output drive than a 4558 (±10 V into 600 Ω).
TLC27M2	CMOS	3–16 V	0.635 MHz	0.56 V/µs	32 nV	0.14 mA	3	CMOS input; 16 V max, not for 18 V; input range reaches the negative rail. Low-power CMOS dual limited to 16 V; slow, with an input range that includes the negative rail.
TLC2262	CMOS, RR out	4.4–16 V	0.73 MHz	0.55 V/µs	12 nV	0.21 mA	25	CMOS input; 16 V max, not for 18 V; input range reaches the negative rail; rail-to-rail output. CMOS rail-to-rail-output dual limited to 16 V total; do not run it on an 18 V rail.
TL062	JFET	10–30 V	1 MHz	3.5 V/µs	30 nV	0.2 mA	127	JFET input. Low-power JFET op-amp at 200 µA per amplifier; common-mode range must stay 4 V inside the rails.
4558	bipolar	10–30 V	4 MHz	2.2 V/µs	7 nV	1.25 mA	1164	Bipolar input with about 80 nA bias current, so it needs a DC bias path on each input.
MC33178	bipolar	4–36 V	5 MHz	2 V/µs	7.5 nV	0.42 mA	35	much faster, may oscillate in a slow part's place. Low-noise bipolar dual that draws only about 0.42 mA per amplifier and drives 600 ohm loads.
