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 8), 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.

| Part | Input | Supply | GBW | Slew | Noise | Iq | Boards |
|---|---|---|---|---|---|---|---|
| TLC2272 | CMOS, RR out | 4.4–16 V | 2.25 MHz | 3.6 V/µs | 9 nV | 1.2 mA | 20 |
CMOS rail-to-rail-output dual limited to 16 V total; do not run it on an 18 V rail.
Fits the same socket
| Part | Input | Supply | GBW | Slew | Noise | Iq | Boards | Differs |
|---|---|---|---|---|---|---|---|---|
| 4558 | bipolar | 10–30 V | 4 MHz | 2.2 V/µs | 7 nV | 1.25 mA | 1164 | bipolar input; rated from 10 V. Bipolar input with about 80 nA bias current, so it needs a DC bias path on each input. |
| 4559 | bipolar | ?–36 V | 4 MHz | 2 V/µs | 1.65 mA | 29 | bipolar input. Audio dual with stronger output drive than a 4558 (±10 V into 600 Ω). | |
| M5218 | 4–32 V | 7 MHz | 3 V/µs | 1.5 mA | 21 | Low-noise audio dual the maker calls close to the 4558 and 4559, with ±50 mA load current. | ||
| CA3260 | mosfet, RR out | 4–16 V | 4 MHz | 10 V/µs | 4.5 mA | 8 | MOSFET input; draws 4.5 mA per amplifier. CMOS output swings to both rails, but the 16 V supply limit rules out 18 V pedals. | |
| TLC272 | CMOS | 3–16 V | 4.5 MHz | 21 V/µs | 10.8 nV | 0.56 mA | 7 | CMOS dual limited to 16 V total; the input range includes the negative rail. |
| MC33178 | bipolar | 4–36 V | 5 MHz | 2 V/µs | 7.5 nV | 0.42 mA | 35 | bipolar input. Low-noise bipolar dual that draws only about 0.42 mA per amplifier and drives 600 ohm loads. |
| NJM4565D | bipolar | 8–36 V | 10 MHz | 4 V/µs | 2.25 mA | 2 | bipolar input; much faster, may oscillate in a slow part's place. Drives 20 V peak-to-peak into 400 Ω; the DIP8 (NJM4565D) is listed as discontinued. | |
| M5216 | 4–32 V | 10 MHz | 3 V/µs | 2.25 mA | 4 | much faster, may oscillate in a slow part's place. High-current dual (±100 mA load) meant for headphone drivers. | ||
| NJM2100 | bipolar | 2–7 V | 12 MHz | 4 V/µs | 1.75 mA | 1 | bipolar input; much faster, may oscillate in a slow part's place. Low-voltage dual op-amp rated to ±3.5 V (7 V total), so it cannot run straight from 9 V. | |
| TL062 | JFET | 10–30 V | 1 MHz | 3.5 V/µs | 30 nV | 0.2 mA | 127 | JFET input; rated from 10 V. Low-power JFET op-amp at 200 µA per amplifier; common-mode range must stay 4 V inside the rails. |
