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 7), 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 |
|---|---|---|---|---|---|---|---|
| OPA2134 | JFET | 5–36 V | 8 MHz | 20 V/µs | 8 nV | 4 mA | 108 |
FET-input audio op-amp without phase inversion; draws about 4 mA per amplifier, so it is hungry on a 9 V battery.
Fits the same socket
| Part | Input | Supply | GBW | Slew | Noise | Iq | Boards | Differs |
|---|---|---|---|---|---|---|---|---|
| TL072 | JFET | 4.5–40 V | 5.25 MHz | 20 V/µs | 37 nV | 1.4 mA | 1338 | JFET input; inputs must stay 4 V above the negative rail, and the input range reaches the positive rail. |
| TL082 | JFET | 4.5–40 V | 5.25 MHz | 20 V/µs | 37 nV | 1.4 mA | 72 | JFET input; inputs must stay 4 V above the negative rail, and the input range reaches the positive rail. |
| LF412 | JFET | 7–36 V | 4.5 MHz | 21 V/µs | 18 nV | 0.56 mA | 4 | FET-input dual with standard pinout per the drawing (the 2026 pin table misprints pins 4 to 8). |
| LF353 | JFET | 7–36 V | 3 MHz | 13 V/µs | 18 nV | 1.8 mA | 73 | JFET dual; common-mode range must stay 4 V inside each rail. |
| TLE2072 | 4.5–38 V | 10.6 MHz | 32 V/µs | 17 nV | 2.4 mA | 1 | Fast, low-bias dual drawing about 2.4 mA per amplifier. | |
| UPC4570 | bipolar | 8–32 V | 15 MHz | 7 V/µs | 2.5 mA | 5 | bipolar input. Low-noise, wideband audio dual; needs at least ±4 V (8 V) supply. | |
| TLC272 | CMOS | 3–16 V | 4.5 MHz | 21 V/µs | 10.8 nV | 0.56 mA | 7 | CMOS input; 16 V max, not for 18 V; input range reaches the negative rail. CMOS dual limited to 16 V total; the input range includes the negative rail. |
| CA3260 | mosfet, RR out | 4–16 V | 4 MHz | 10 V/µs | 4.5 mA | 8 | MOSFET input; 16 V max, not for 18 V; input range reaches the negative rail; rail-to-rail output. CMOS output swings to both rails, but the 16 V supply limit rules out 18 V pedals. | |
| NJM4565D | bipolar | 8–36 V | 10 MHz | 4 V/µs | 2.25 mA | 2 | bipolar input; much slower. Drives 20 V peak-to-peak into 400 Ω; the DIP8 (NJM4565D) is listed as discontinued. | |
| 4580 | bipolar | 4–36 V | 15 MHz | 5 V/µs | 3 mA | 103 | bipolar input. Low-noise, high-output-current audio dual from ±2 V; the DIP8 (NJM4580D) is listed as discontinued. |
