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.
This part
| Part | Input | Supply | GBW | Slew | Noise | Iq | Boards |
|---|---|---|---|---|---|---|---|
| 1458 | bipolar | 10–30 V | 1 MHz | 0.5 V/µs | 45 nV | 1.7 mA | 209 |

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. |
