Supply Chain & Allocation Reality:

The TL071 is the single-channel member of the low-noise JFET-input family that ran the analog benches of the 1980s and still repairs them - audio front ends, instrumentation, filters, sample-and-holds and half of every synth ever: TL071 single, TL072 dual, TL074 quad, with the TL08x twins (TL081/082/084) as the higher-noise, otherwise interchangeable siblings. The channel-count letter is the socket definition, the A/B suffix is offset grade, and the family quirks - offset-null pins on the single only, and phase inversion near the negative rail - are what substitutions in this family actually get wrong.

Same Socket, Higher Noise

Shenzhen Spot Stock (24-48h Dispatch)

Electrical & Core Specs:

The same JFET-input architecture and pinout with noise around 25 nV/root-Hz against about 18 for the TL071 - the low-noise selection came from the 07x die.

Same supply envelopes and slew (about 13V/us), same 3MHz-class gain-bandwidth.

Compatibility & Drop-In Notes: Interchangeable in most circuits; in critical noise positions (phono stages, low-level instrumentation) the 081 replacement raises the noise floor visibly on the bench. Prefer the 07x in those positions.
Package & Solder Footprint: DIP-8 / SOIC-8, identical pin map.

The Battery-Diet Sibling

Shenzhen Spot Stock (24-48h Dispatch)

Electrical & Core Specs:

The low-power member of the family: same JFET inputs and pinout, supply current cut to the microamp-conscious class at the cost of bandwidth (about 1MHz class against 3MHz).

Same envelopes; designed for portable instruments.

Compatibility & Drop-In Notes: Fine in slow sensor conditioning; in filter and audio designs tuned around the 07x bandwidth, the reduced GBW shifts poles and the circuit changes character. Match the letter to the role.
Package & Solder Footprint: Same 8-pin body.

The Dual - Same Die, Different Count

Shenzhen Spot Stock (24-48h Dispatch)

Electrical & Core Specs:

Two channels of the same amplifier in the classic dual pinout (1 OUT1, 2 IN1-, 3 IN1+, 4 V-, 5 IN2+, 6 IN2-, 7 OUT2, 8 V+): no offset-null pins in this body.

Same supply and slew per channel.

Compatibility & Drop-In Notes: Listed for the comparison, not as a substitution: an 8-pin dual cannot replace an 8-pin single. The practical note is the reverse one - half the TL072 boards run one channel unused, and the spare channel is often the correct place for an added stage.
Package & Solder Footprint: Dual pinout differs completely from the single (no null pins, second channel fills pins 5-7).

The Modern Re-issue - a Different Animal

Shenzhen Spot Stock (24-48h Dispatch)

Electrical & Core Specs:

TIs 2020-era successor: same pinout and socket, but a CMOS input stage instead of JFET - about 20V/us slew, 1mV-class offset, and different noise character (about 37 nV/root-Hz).

Wider modern supply window (about +/-2.25V to +/-20V).

Compatibility & Drop-In Notes: Fits and works in most TL071 circuits, but the input stage physics changed: bias currents, noise spectrum and phase-inversion behavior all differ. In designs built around JFET input parameters, verify before standardizing; for new builds it is the current part.
Package & Solder Footprint: Same DIP-8 / SOIC-8 pin function.
Shenzhen Warehouse Stock & MOQ: Active TI production; the long-term buy for new designs.

Buyer & Quality Checklist for Sourcing Alternatives
  • The offset-null pins exist on the singles only (TL071 / TL081, pins 1 and 5). The dual and quad bodies have no null pins - a substitution across channel counts is a different socket, not a replacement.
  • Phase-inversion is a real family quirk: when an input is driven below the negative-rail common-mode limit (about 3V above VCC-), the output can flip state. In single-supply sensor circuits that look noisy or inverted near ground, this is usually the cause - clamp the input or add a series resistor.
  • Noise grading is the 07x-versus-08x line: about 18 against 25 nV/root-Hz. In low-level audio, swapping a 071 for an 081 is measurable; swapping upward is always safe.
  • Suffix grades: B (3mV offset max), A (6mV), plain (10-15mV), times temperature C/I/M. Precision DC work wants the A or B part; audio rarely cares.
  • The historical cross-branding is worth knowing at the bench: LF351-class parts were second-sourced against the TL081 and the names wander across databooks. When crossing brands in this family, compare offset and noise rather than trusting the prefix.
  • JFET inputs have tiny bias current - the reason this family holds DC accuracy in high-impedance dividers. Preserve the advantage: keep board leakage low, clean flux, and do not populate a bipolar-input substitute casually in those positions.
Frequently Asked Technical Questions

Q: What is the difference between TL071 and TL081?

A: Same architecture, pinout and grade system - the 07x family is the low-noise selection of the 08x family (about 18 vs 25 nV/root-Hz). Interchangeable everywhere; in low-level audio or instrumentation the 081 replacement raises the noise floor.

Q: Can a TL072 replace a TL071?

A: No - the 072 is the dual-channel member with a completely different 8-pin layout and no offset-null pins. Same die per channel, different socket definition.

Q: Why does my TL071 circuit misbehave near ground on a single supply?

A: The family phase-inverts when the input is driven below its common-mode limit (roughly 3V above the negative rail). Symptom: the output flips high instead of staying off. Keep inputs inside the common-mode window or raise the negative rail.

Technical details

What this JFET op-amp brings to the board

The TL081HIDR is a single JFET-input operational amplifier from Texas Instruments in an 8-SOIC package. It delivers a 5.25 MHz gain-bandwidth product and a 20 V/µs slew rate, with a 1 pA input bias current that keeps high-impedance sensor signals clean. Supply range runs from 4.5 V to 40 V, and the push-pull output stage handles loads without external pull-up resistors.

Slew rate and bandwidth — what they mean for signal fidelity

The 20 V/µs slew rate supports 5.25 MHz gain-bandwidth product. For active filters or ADC driver stages, the 5.25 MHz GBW provides closed-loop gain before roll-off.

8-SOIC (3.90 mm width) — standard footprint, easy to hand-solder or hot-air rework. Pin 1 is clearly marked on the package top.

Marked as Active in production — no end-of-life notice on this variant.
