Datasheet · from ti.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 15), 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.

|---|---|---|---|---|---|---|---|---|
| TL084 | JFET | 4.5–40 V | 5.25 MHz | 20 V/µs | 37 nV | 1.4 mA | 15 | JFET quad; inputs must stay 4 V above the negative rail. |
| LF347 | JFET | 7–36 V | 3 MHz | 13 V/µs | 18 nV | 2 mA | 20 | JFET quad; common-mode range must stay 4 V inside each rail. |
| TL974 | RR out | 2.7–12 V | 10.6 MHz | 2.48 mA | 1 | 12 V max, not for 18 V; rail-to-rail output. Low-noise quad (4.4 nV/√Hz at 100 kHz) limited to 12 V total; it will not survive an 18 V rail. | ||
| TLE2074 | 4.5–38 V | 10.6 MHz | 32 V/µs | 17 nV | 2.4 mA | 20 | Fast, low-bias quad drawing about 2.4 mA per amplifier; the input range reaches the positive rail but stops 4 V above the negative one. | |
| TL064 | JFET | 10–30 V | 1 MHz | 3.5 V/µs | 30 nV | 0.2 mA | 17 | rated from 10 V; much slower. Low-power JFET quad at 200 µA per amplifier. |
| MC33179 | bipolar | 4–36 V | 5 MHz | 2 V/µs | 7.5 nV | 0.425 mA | 2 | bipolar input; much slower. Quad version of the MC33178 in the standard quad pinout. |
| TLC2274 | CMOS, RR out | 4.4–16 V | 2.25 MHz | 3.6 V/µs | 9 nV | 1.2 mA | 1 | CMOS input; 16 V max, not for 18 V; input range reaches the negative rail; rail-to-rail output; much slower. CMOS rail-to-rail-output quad limited to 16 V total. |
| LF444 | JFET | ?–36 V | 1 MHz | 1 V/µs | 35 nV | 0.15 mA | 4 | much slower. Low-power JFET quad at about 150 µA per amplifier. |
| TLC27M4AIN | CMOS | 3–16 V | 1.1 MHz | 4.5 V/µs | 32 nV | 0.06 mA | 8 | CMOS input; 16 V max, not for 18 V; input range reaches the negative rail; much slower. Low-power CMOS quad limited to 16 V; the input range includes the negative rail (single-supply friendly). |
| LMC660CN | CMOS, RR out | 4.75–15.5 V | 1.4 MHz | 1.1 V/µs | 22 nV | 0.4 mA | 4 | CMOS input; 15.5 V max, not for 18 V; input range reaches the negative rail; rail-to-rail output; much slower. CMOS quad limited to 15.5 V total; rail-to-rail output and an input range that includes ground. |
