TL072IDE4 Equivalent & Substitute Parts Reference

Part Overview

The TL072IDE4 is a J-FET input operational amplifier with dual circuit configuration in 8-SOIC surface mount packaging, manufactured by Texas Instruments. This device is classified as obsolete product status. The TL072IDE4 serves applications requiring low input bias current and low input offset voltage characteristics typical of J-FET amplifier designs. Due to obsolete product status, equivalent and substitute parts from active product lines are necessary for ongoing design support, production continuity, and long-term component availability.

Substitute Part Grouping Explanation

Substitution logic for the TL072IDE4 is based on the following critical parameters that must align for functional equivalence:

Primary Substitution Criteria:

Amplifier Type: J-FET (low input bias current requirement)
Number of Circuits: 2 (dual configuration)
Package / Case: 8-SOIC form factor (mechanical compatibility)
Mounting Type: Surface Mount (assembly compatibility)
Voltage - Supply Span: Minimum 10V to 30V maximum (power supply compatibility)
Operating Temperature Range: Support for -40°C to 85°C minimum

Secondary Compatibility Parameters:

Slew Rate: 13 V/µs or higher (signal fidelity)
Gain Bandwidth Product: 5.25 MHz or higher (frequency response)
Current - Input Bias: 65 pA or lower (input impedance characteristics)
Voltage - Input Offset: 3 mV or lower (DC accuracy)

Substitute parts are grouped into two categories: direct J-FET equivalents maintaining identical electrical characteristics, and alternative amplifier types (Audio, General Purpose) that share mechanical packaging and basic operational parameters but differ in amplifier topology and performance specifications.

Engineering Selection Recommendations

Direct Equivalent (Active Product Status):

TL072IDR from Texas Instruments is the direct active equivalent to TL072IDE4. This part maintains identical electrical specifications including 13 V/µs slew rate, 5.25 MHz gain bandwidth product, 65 pA input bias current, and -40°C to 85°C operating temperature range. Both parts are J-FET amplifiers in 8-SOIC packaging with identical supply voltage requirements (10V to 30V). TL072IDR is available in Cut Tape and Digi-Reel packaging with 35,200 pieces in stock inventory.

J-FET Amplifier Alternatives (Active Product Status):

TL072IDT, TL072CDT, TL072BIDT, TL072BIYDT, and TL072ACDT from STMicroelectronics are J-FET amplifier alternatives sharing the same base product number (TL072) and 8-SOIC package. These parts feature improved slew rate (16 V/µs) and extended supply voltage range (6V to 36V). TL072IDT and TL072BIDT support the full -40°C to 125°C temperature range. TL072CDT and TL072ACDT operate within 0°C to 70°C range. All variants carry AEC-Q100 automotive qualification and are available in active product status with substantial inventory levels.

Alternative Amplifier Types (Active Product Status):

MC33172D and MC33172DT are General Purpose amplifiers with 8-SOIC packaging and active product status. These parts support wider supply voltage range (4V to 44V) and extended temperature operation (-40°C to 105°C). However, they feature significantly lower input bias current (20 nA versus 65 pA) and reduced slew rate (2 V/µs versus 13 V/µs), making them suitable only for applications where J-FET input characteristics are not critical.

LM833DT is an Audio amplifier with active product status, 8-SOIC packaging, and higher gain bandwidth product (15 MHz). This part is not recommended as a direct substitute due to fundamentally different amplifier topology (Audio versus J-FET) and substantially higher input bias current (300 nA).

Compliance and Certification:

All substitute parts listed are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity rating. TL072 variants from STMicroelectronics include AEC-Q100 automotive qualification. Selection should prioritize active product status parts for long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can TL072IDR directly replace TL072IDE4 in existing designs?

A: Yes. TL072IDR from Texas Instruments is the direct active equivalent with identical electrical specifications, J-FET amplifier type, dual circuit configuration, and 8-SOIC packaging. Both parts support -40°C to 85°C operating temperature and 10V to 30V supply voltage range. No design modifications are required.

Q: What is the difference between TL072IDT and TL072CDT?

A: Both are STMicroelectronics J-FET amplifiers in 8-SOIC packaging with identical electrical performance (16 V/µs slew rate, 4 MHz gain bandwidth product). The primary difference is operating temperature range: TL072IDT supports -40°C to 125°C, while TL072CDT operates within 0°C to 70°C. TL072IDT is suitable for extended temperature applications; TL072CDT is appropriate for commercial temperature range requirements.

Q: Why do TL072BIDT and TL072BIYDT have different input offset voltage specifications?

A: Both parts are identical J-FET amplifiers with 1 mV input offset voltage specification (improved from the 3 mV of standard TL072 variants). The difference is packaging format: TL072BIDT is supplied in Cut Tape and Digi-Reel format, while TL072BIYDT is supplied in Tape & Reel format. Electrical performance is equivalent.

Q: Can MC33172 series replace TL072 in audio applications?

A: MC33172D and MC33172DT are General Purpose amplifiers, not J-FET amplifiers. While they share 8-SOIC packaging and support similar supply voltage ranges, they feature significantly different input characteristics (20 nA input bias current versus 65 pA for TL072IDE4) and lower slew rate (2 V/µs versus 13 V/µs). Substitution is not recommended for applications requiring J-FET input impedance characteristics.

Q: Is LM833DT suitable as a substitute for TL072IDE4?

A: No. LM833DT is an Audio amplifier with fundamentally different topology from the J-FET amplifier design of TL072IDE4. While both are dual-circuit 8-SOIC devices, LM833DT features 300 nA input bias current (compared to 65 pA), 7 V/µs slew rate (compared to 13 V/µs), and 15 MHz gain bandwidth product (compared to 5.25 MHz). Substitution would alter circuit performance characteristics.

Q: What packaging options are available for TL072 J-FET amplifier substitutes?

A: TL072IDR is available in Cut Tape (CT) and Digi-Reel packaging. TL072IDT, TL072CDT, TL072BIDT, and TL072ACDT are supplied in Cut Tape and Digi-Reel format. TL072BIYDT is supplied in Tape & Reel (TR) format. All variants use identical 8-SOIC (0.154", 3.90mm Width) package case. Selection should match assembly line requirements and tape specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (TL072IDR, TL072IDT, TL072CDT, TL072BIDT, TL072BIYDT, TL072ACDT, MC33172D, MC33172DT, LM833DT) are ROHS3 compliant and REACH unaffected. All carry MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute offers the widest supply voltage range?

A: MC33172D and MC33172DT support the widest supply voltage range (4V to 44V). However, these are General Purpose amplifiers, not J-FET amplifiers. Among J-FET amplifier substitutes, TL072 variants from STMicroelectronics (TL072IDT, TL072CDT, TL072BIDT, TL072BIYDT, TL072ACDT) support 6V to 36V supply range, compared to 10V to 30V for TL072IDE4 and TL072IDR.

Q: What inventory levels are available for active substitute parts?

A: TL072IDR (Texas Instruments) has 35,200 pieces in stock. Among STMicroelectronics J-FET variants: TL072CDT has 203,200 pieces, TL072IDT has 55,200 pieces, TL072BIYDT has 3,600 pieces, TL072BIDT has 1,249 pieces, and TL072ACDT has 6,546 pieces.
