TL072ACDE4 Equivalent & Substitute Parts

Part Overview

The TL072ACDE4 is a J-FET input operational amplifier featuring two independent circuits in an 8-SOIC surface mount package. Manufactured by Texas Instruments, this device is classified as obsolete but remains in stock with 1,227 units available. The TL072ACDE4 is designed for applications requiring low input bias current and low input offset voltage characteristics typical of J-FET amplifier designs.

Due to its obsolete product status, identifying equivalent and substitute parts is essential for design continuity, procurement planning, and long-term supply chain management. Substitute parts must maintain functional compatibility through matching electrical specifications and package form factors.

Substitute Part Grouping Explanation

Substitution of the TL072ACDE4 is determined by the following critical parameters:

Primary Substitution Criteria:

Amplifier Type: J-FET (low input bias current requirement)
Number of Circuits: 2 (dual-channel configuration)
Package / Case: 8-SOIC form factor (mechanical and electrical compatibility)
Mounting Type: Surface Mount (PCB assembly compatibility)

Secondary Compatibility Parameters:

Slew Rate: 13 V/µs minimum (signal fidelity in time-sensitive applications)
Gain Bandwidth Product: 5.25 MHz minimum (frequency response capability)
Current - Input Bias: 65 pA maximum (input impedance characteristics)
Voltage - Input Offset: 3 mV maximum (DC accuracy)
Supply Voltage Range: 10 V to 30 V (power supply compatibility)
Operating Temperature: 0°C to 70°C (thermal operating envelope)

Substitute parts are grouped into two categories: direct J-FET replacements maintaining identical electrical specifications, and alternative amplifier topologies (General Purpose, Audio) that provide functional equivalence within the 8-SOIC package while accepting trade-offs in specific parameters such as input bias current or slew rate.

Engineering Selection Recommendations

Tier 1: Direct Functional Equivalents (Active Product Status)

The TL072ACDR (Texas Instruments) and TL072ACDT (STMicroelectronics) are the primary recommended substitutes for the obsolete TL072ACDE4. Both maintain identical electrical specifications including 13–16 V/µs slew rate, 3–5.25 MHz gain bandwidth product, and 65 pA input bias current. The TL072ACDR is currently in active production with 47,600 units in stock, providing superior long-term supply availability. Both parts are ROHS3 compliant and carry identical ECCN and HTSUS classifications.

Tier 2: J-FET Amplifiers with Extended Temperature Range (Active Product Status)

The TL072BIDT and TL072BIYDT offer extended operating temperature range (-40°C to 125°C) compared to the original specification (0°C to 70°C). These parts feature improved input offset voltage (1 mV versus 3 mV) and automotive-grade qualification (AEC-Q100). Selection of these parts is appropriate for applications requiring enhanced thermal performance or automotive compliance. The TL072BIYDT is supplied in Tape & Reel packaging with 3,600 units available.

Tier 3: Alternative Amplifier Topologies (Active Product Status)

The MC33172DT and MC33172D (General Purpose amplifiers) and MC4558IDT provide functional substitution within the 8-SOIC package. These alternatives accept trade-offs in slew rate (2–2.2 V/µs versus 13 V/µs) and input bias current (20–50 nA versus 65 pA) in exchange for extended supply voltage range (4–44 V) and wider operating temperature (-40°C to 105°C). The LM833DT (Audio amplifier) offers the highest gain bandwidth product (15 MHz) but exhibits significantly higher input bias current (300 nA) and is suitable only for applications where J-FET input characteristics are not critical.

Compliance and Certification:

All recommended substitutes maintain ROHS3 compliance, MSL Level 1 (Unlimited), and REACH Unaffected status. Automotive-qualified variants (TL072ACDT, TL072BIDT, TL072BIYDT) carry AEC-Q100 qualification.

Frequently Asked Questions (FAQ)

Q: Can the TL072ACDE4 be directly replaced with the TL072ACDR?

A: Yes. The TL072ACDR is a direct functional equivalent with identical electrical specifications (13 V/µs slew rate, 5.25 MHz gain bandwidth product, 65 pA input bias current) and identical 8-SOIC package form factor. The primary difference is product status: TL072ACDR is active production with significantly higher inventory availability (47,600 units).

Q: What is the difference between TL072ACDT and TL072BIDT?

A: Both are J-FET amplifiers in 8-SOIC packages manufactured by STMicroelectronics. The TL072ACDT operates from 0°C to 70°C with 3 mV input offset voltage. The TL072BIDT extends the operating range to -40°C to 125°C and reduces input offset voltage to 1 mV. The TL072BIDT carries automotive-grade AEC-Q100 qualification. Selection depends on thermal requirements and offset voltage tolerance.

Q: Can I use MC33172DT as a substitute for TL072ACDE4?

A: MC33172DT provides functional substitution within the 8-SOIC package but is not a direct equivalent. It is a General Purpose amplifier with significantly lower slew rate (2 V/µs versus 13 V/µs) and higher input bias current (20 nA versus 65 pA). Use MC33172DT only in applications where J-FET input characteristics are not required and where the lower slew rate is acceptable.

Q: What packaging options are available for TL072 substitutes?

A: Substitute parts are available in multiple packaging configurations: Cut Tape (CT) & Digi-Reel® (TL072ACDR, TL072ACDT, TL072BIDT, MC33172DT, MC4558IDT), Tube (TL072ACD, MC33172D), and Tape & Reel (TR) (TL072BIYDT). All maintain the 8-SOIC (0.154", 3.90mm Width) form factor for PCB compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All recommended substitute parts listed in this document are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status.

Q: Which substitute offers the best long-term supply availability?

A: The TL072ACDR (Texas Instruments, Active status) offers the highest inventory with 47,600 units in stock and active production status, providing the most reliable long-term supply chain continuity.

Q: Can I substitute TL072ACDE4 with LM833DT?

A: LM833DT is an Audio amplifier topology with different electrical characteristics. It features higher gain bandwidth product (15 MHz) but significantly higher input bias current (300 nA versus 65 pA) and lower slew rate (7 V/µs versus 13 V/µs). Use LM833DT only in audio applications where J-FET input performance is not required.
