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 2), 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 |
|---|---|---|---|---|---|---|---|
| CA3130 | mosfet, RR out | 5–16 V | 4 MHz | 10 V/µs | 10 mA | 54 |
Needs a 47 pF capacitor between pins 1 and 8 for unity-gain stability (15 MHz uncompensated) and is limited to 16 V total supply.
Fits the same socket
| Part | Input | Supply | GBW | Slew | Noise | Iq | Boards | Differs |
|---|---|---|---|---|---|---|---|---|
| CA3140 | mosfet | 4–36 V | 4.5 MHz | 9 V/µs | 40 nV | 4 mA | 12 | internally compensated: the board's capacitor across pins 1 and 8 no longer shapes the tone; pins 1, 5, 8 are offset null (1, 5), strobe (8). MOSFET input that reaches 0.5 V below the negative rail, internally compensated; draws about 4 mA. |
| LM308 | bipolar | 10–36 V | 0.3 mA | 96 | bipolar input; rated from 10 V. Needs a compensation capacitor (30 pF typical) between pins 1 and 8; the cap sets slew rate and tone. | |||
| LF356 | JFET | ?–36 V | 5 MHz | 12 V/µs | 12 nV | 5 mA | 14 | JFET input; internally compensated: the board's capacitor across pins 1 and 8 no longer shapes the tone; pins 1, 5, 8 are offset null (1, 5), NC (8). JFET single drawing about 5 mA; specified at ±15 V. |
| TL051 | JFET | 10–30 V | 4.5 MHz | 17.8 V/µs | 10.8 nV | 2.1 mA | 8 | JFET input; internally compensated: the board's capacitor across pins 1 and 8 no longer shapes the tone; pins 1, 5, 8 are NC; rated from 10 V. Trimmed-offset upgrade for the TL071/TL081; pins 1, 5 and 8 are no-connect in this revision. |
| LM301A | bipolar | 10–36 V | 1 V/µs | 1.8 mA | 23 | bipolar input; rated from 10 V; much slower. Externally compensated: needs a capacitor (30 pF for unity gain) between pins 1 and 8, and the value sets its slew and treble response in fuzz and distortion circuits. | ||
| NE5534 | bipolar | 10–30 V | 10 MHz | 13 V/µs | 4 nV | 4 mA | 44 | bipolar input; needs a compensation capacitor across pins 5 and 8; rated from 10 V. Compensated for a gain of 3 or more; below that it needs a capacitor (22 pF) between pins 5 and 8. |
| TL071 | JFET | 4.5–40 V | 5.25 MHz | 20 V/µs | 37 nV | 1.4 mA | 178 | JFET input; internally compensated: the board's capacitor across pins 1 and 8 no longer shapes the tone; pins 1, 5, 8 are NC (offset null on pins 1 and 5 only in the PS package). JFET input; this revision shows pins 1, 5 and 8 as no-connect on the DIP, so no offset trim. |
| TL081 | JFET | 4.5–40 V | 5.25 MHz | 20 V/µs | 37 nV | 1.4 mA | 20 | JFET input; internally compensated: the board's capacitor across pins 1 and 8 no longer shapes the tone; pins 1, 5, 8 are NC (offset null on pins 1 and 5 only in the PS package). JFET input; this revision shows no offset-null pins on the DIP. |
| LF355 | JFET | ?–36 V | 2.5 MHz | 5 V/µs | 20 nV | 2 mA | 1 | JFET input; internally compensated: the board's capacitor across pins 1 and 8 no longer shapes the tone; pins 1, 5, 8 are offset null (1, 5), NC (8). Lower-power, slower sibling of the LF356. |
| OPA134 | JFET | 5–36 V | 8 MHz | 20 V/µs | 8 nV | 4 mA | 3 | JFET input; internally compensated: the board's capacitor across pins 1 and 8 no longer shapes the tone; pins 1, 5, 8 are NC (1 and 5 do not connect, 8 no internal connection). FET-input audio op-amp with no offset null; leave pins 1, 5 and 8 unconnected. |
