TL072ACD Equivalent & Substitute Parts

Part Overview

The TL072ACD is a J-FET input operational amplifier featuring dual circuits in an 8-SOIC surface mount package, manufactured by Texas Instruments. This device is classified as obsolete, though 1,708 units remain in stock as new original inventory. The TL072ACD operates across a supply voltage range of 10V to 30V with a slew rate of 13V/µs and gain bandwidth product of 5.25 MHz, making it suitable for audio and precision signal conditioning applications requiring low input bias current (65 pA) and low input offset voltage (3 mV).

Due to its obsolete status, identifying equivalent and substitute parts is essential for design continuity, long-term availability assurance, and supply chain planning. Active alternatives with identical or superior electrical characteristics are available from multiple manufacturers.

Substitute Part Grouping Explanation

Substitution of the TL072ACD is determined by strict alignment of electrical and mechanical parameters within the 8-SOIC package form factor. The critical parameters governing substitution eligibility are:

Primary Substitution Criteria:

Package / Case: 8-SOIC (0.154", 3.90mm Width) — mandatory for mechanical compatibility
Number of Circuits: 2 — required for functional equivalence
Mounting Type: Surface Mount — required for PCB assembly compatibility
Amplifier Type: J-FET or General Purpose — acceptable for signal conditioning applications
Voltage - Supply Span: minimum 10V to 30V overlap required
Operating Temperature: 0°C to 70°C minimum coverage required

Secondary Alignment Parameters:

Slew Rate: 13V/µs baseline; higher values acceptable
Gain Bandwidth Product: 5.25 MHz baseline; higher values acceptable
Current - Input Bias: 65 pA baseline; lower values acceptable
Voltage - Input Offset: 3 mV baseline; lower values acceptable
Current - Supply: 1.4 mA baseline; lower values preferred for power efficiency

Substitute parts are grouped into two categories: Direct J-FET Equivalents (TL072ACDR, ADTL082ARZ, TL072ACDT) and General Purpose Alternatives (MC33172D, MC33172DT, MC33172VDR2G, MC34072DR2G, MC4558CDT, TJM4558CDT, LM833DT). Direct J-FET equivalents maintain identical amplifier topology. General Purpose alternatives provide functional substitution with modified electrical characteristics suitable for non-critical audio and signal conditioning applications.

Engineering Selection Recommendations

Direct J-FET Equivalents (Highest Compatibility):

TL072ACDR (Texas Instruments, Active) is the primary recommended substitute. It maintains identical electrical specifications to the TL072ACD while offering active product status and significantly higher inventory availability (47,600 units). The packaging format (Cut Tape & Digi-Reel) ensures supply chain continuity. This part is suitable for direct replacement in all applications where the TL072ACD was originally specified.

TL072ACDT (STMicroelectronics, Active) provides an alternative J-FET equivalent with enhanced slew rate (16V/µs vs. 13V/µs) and extended supply voltage range (6V to 36V vs. 10V to 30V). This part includes AEC-Q100 automotive qualification, making it suitable for automotive-grade applications. Current inventory is 6,546 units.

ADTL082ARZ (Analog Devices Inc., Active) offers superior electrical performance with lower input bias current (2 pA vs. 65 pA), lower input offset voltage (1.5 mV vs. 3 mV), and higher slew rate (20V/µs vs. 13V/µs). Extended operating temperature range (-40°C to 125°C) and wider supply voltage range (8V to 36V) provide additional design flexibility. Inventory: 13,125 units.

General Purpose Alternatives (Functional Substitution):

MC33172D and MC33172DT (STMicroelectronics, Active) provide general purpose amplification with significantly reduced supply current (220 µA vs. 1.4 mA), making them suitable for low-power applications. However, reduced slew rate (2V/µs) and gain bandwidth product (2.1 MHz) limit use to non-critical audio and low-frequency signal conditioning. Extended supply voltage range (4V to 44V) and operating temperature (-40°C to 105°C) offer design advantages. Inventory: 100,400 units (MC33172D) and 45,300 units (MC33172DT).

All substitute parts maintain ROHS3 compliance and identical 8-SOIC package specifications.

Frequently Asked Questions (FAQ)

Q: Can TL072ACDR be used as a direct replacement for TL072ACD?

A: Yes. TL072ACDR maintains identical electrical specifications (slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and supply voltage range) and identical 8-SOIC package form factor. The primary difference is product status (Active vs. Obsolete) and packaging format (Cut Tape & Digi-Reel vs. Tube). Direct substitution is supported without circuit modification.

Q: What is the difference between J-FET and General Purpose amplifier types?

A: J-FET input amplifiers feature extremely low input bias current (measured in picoamperes) and are suitable for high-impedance signal sources and precision instrumentation. General Purpose amplifiers have higher input bias current (measured in nanoamperes) but offer lower supply current and wider supply voltage ranges. For applications requiring high input impedance or low bias current, J-FET types (TL072ACDR, ADTL082ARZ, TL072ACDT) are required. For general audio and moderate-precision applications, General Purpose types are acceptable.

Q: Is ADTL082ARZ compatible with the TL072ACD?

A: ADTL082ARZ is mechanically and functionally compatible. It maintains the same 8-SOIC package and dual-circuit configuration. Electrically, ADTL082ARZ offers superior performance: lower input bias current (2 pA vs. 65 pA), lower input offset voltage (1.5 mV vs. 3 mV), and higher slew rate (20V/µs vs. 13V/µs). Extended operating temperature range (-40°C to 125°C vs. 0°C to 70°C) and wider supply voltage range (8V to 36V vs. 10V to 30V) provide additional design margin. No circuit modification is required.

Q: Can MC33172D replace TL072ACD in audio applications?

A: MC33172D is mechanically compatible (8-SOIC package, dual circuits) but electrically different. It features significantly lower supply current (220 µA vs. 1.4 mA), making it suitable for battery-powered audio applications. However, reduced slew rate (2V/µs vs. 13V/µs) and lower gain bandwidth product (2.1 MHz vs. 5.25 MHz) limit frequency response. MC33172D is suitable for low-frequency audio and general signal conditioning but not for high-fidelity or high-speed applications where TL072ACD was originally specified.

Q: What is the advantage of TL072ACDT over TL072ACDR?

A: TL072ACDT offers enhanced electrical performance and extended operating range compared to TL072ACDR. Slew rate is increased to 16V/µs (vs. 13V/µs), and supply voltage range is extended to 6V to 36V (vs. 10V to 30V). TL072ACDT includes AEC-Q100 automotive qualification, making it suitable for automotive-grade applications. However, inventory is lower (6,546 units vs. 47,600 units). For non-automotive applications, TL072ACDR is preferred due to higher availability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (TL072ACDR, ADTL082ARZ, TL072ACDT, MC33172D, MC33172DT, MC33172VDR2G, MC34072DR2G, MC4558CDT, TJM4558CDT, LM833DT) are ROHS3 compliant. All maintain Moisture Sensitivity Level (MSL) 1 (Unlimited) and REACH Unaffected status, matching the TL072ACD compliance profile.

Q: Which substitute offers the lowest power consumption?

A: MC33172D, MC33172DT, and MC33172VDR2G offer the lowest supply current at 220 µA per channel, compared to 1.4 mA for the TL072ACD. These parts are suitable for battery-powered and low-power applications. However, reduced slew rate (2V/µs to 2.1V/µs) and lower gain bandwidth product (1.8 MHz to 2.1 MHz) must be considered for frequency-dependent applications.

Q: What is the operating temperature range difference between substitutes?

A: TL072ACD and most direct equivalents operate from 0°C to 70°C. Extended-range alternatives include: ADTL082ARZ (-40°C to 125°C), MC33172D and MC33172DT (-40°C to 105°C), MC33172VDR2G (-40°C to 125°C), and LM833DT (-40°C to 105°C). Extended temperature range is required for industrial, automotive, and aerospace applications.

Q: Can LM833DT be used in precision instrumentation?

A: LM833DT is classified as an Audio amplifier and is not recommended for precision instrumentation. Input offset voltage is 300 µV (vs. 3 mV for TL072ACD), and input bias current is 300 nA (vs. 65 pA for TL072ACD). These characteristics make LM833DT unsuitable for high-impedance signal sources or precision measurement applications. For precision instrumentation, use J-FET types: TL072ACDR, ADTL082ARZ, or TL072ACDT.
