TL072ID Equivalent & Substitute Parts Reference

Part Overview

The TL072ID 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 but remains in stock with 1,458 units available. The TL072ID is designed for applications requiring low input bias current, low input offset voltage, and moderate slew rate performance. Due to its obsolete status, equivalent substitute parts with active product status are necessary for new designs and long-term supply chain continuity.

Engineering Selection Recommendations

Direct Substitutes (Identical Electrical Performance):

TL072IDR is the primary recommended substitute. This part is manufactured by Texas Instruments with identical electrical specifications to the TL072ID (13 V/µs slew rate, 5.25 MHz gain bandwidth product, 65 pA input bias current). The only difference is packaging format: TL072IDR is supplied in Cut Tape (CT) & Digi-Reel® format instead of Tube. Both parts maintain ROHS3 compliance and MSL 1 rating. TL072IDR has 35,200 units in stock and active product status, ensuring long-term availability.

J-FET Substitutes (Enhanced Performance, Automotive Grade):

TL072IDT, TL072BIDT, TL072BIYDT, TL072CDT, TL072ACDT, and TL082ACDT are all J-FET input operational amplifiers in 8-SOIC packages with active product status. These parts feature improved slew rate (16 V/µs versus 13 V/µs), lower input bias current (20 pA versus 65 pA), and extended supply voltage range (6V to 36V versus 10V to 30V). All are AEC-Q100 qualified automotive grade components. Operating temperature ranges vary: TL072IDT and TL072BIDT support -40°C to 125°C (extended range), while TL072CDT and TL072ACDT support 0°C to 70°C (commercial automotive). TL072BIDT and TL072BIYDT feature improved input offset voltage (1 mV versus 3 mV). Selection among these variants depends on specific temperature range and packaging requirements (Cut Tape, Tape & Reel, or Tube).

Functional Alternatives (Different Amplifier Type):

LM833DT (Audio Amplifier) and MC33172D/MC33172DT (General Purpose Amplifier) are functional alternatives with different electrical characteristics. These parts are not direct substitutes due to different amplifier types and performance parameters. LM833DT features higher gain bandwidth product (15 MHz) but lower slew rate (7 V/µs) and significantly higher input bias current (300 nA). MC33172 series features lower slew rate (2 V/µs) and gain bandwidth product (2.1 MHz) but supports wider supply voltage range (4V to 44V). These alternatives are suitable only for applications where the specific performance characteristics of the TL072ID are not critical.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. All parts are classified under ECCN EAR99 and HTSUS 8542.33.0001. REACH status is unaffected for all listed parts.

Frequently Asked Questions (FAQ)

Q: Can TL072IDR be used as a direct replacement for TL072ID?

A: Yes. TL072IDR is electrically identical to TL072ID with matching slew rate (13 V/µs), gain bandwidth product (5.25 MHz), input bias current (65 pA), and input offset voltage (3 mV). Both support 10V to 30V supply range and -40°C to 85°C operating temperature. The only difference is packaging: TL072IDR is supplied in Cut Tape (CT) & Digi-Reel® format instead of Tube. Both are surface mount 8-SOIC packages with identical pinout and footprint.

Q: What is the difference between TL072IDT and TL072BIDT?

A: Both are J-FET input operational amplifiers in 8-SOIC packages with identical slew rate (16 V/µs), gain bandwidth product (4 MHz), and input bias current (20 pA). The primary difference is input offset voltage: TL072IDT specifies 3 mV while TL072BIDT specifies 1 mV. TL072BIDT offers tighter input offset voltage specification. Both support -40°C to 125°C operating temperature and are AEC-Q100 qualified automotive grade.

Q: Why do TL072 variants from STMicroelectronics have different electrical specifications than the Texas Instruments TL072ID?

A: STMicroelectronics TL072 variants (TL072IDT, TL072BIDT, TL072CDT, TL072ACDT) feature improved performance specifications compared to the original Texas Instruments TL072ID. These include higher slew rate (16 V/µs versus 13 V/µs), lower input bias current (20 pA versus 65 pA), and extended supply voltage range (6V to 36V versus 10V to 30V). These are enhanced versions of the TL072 design and are fully compatible substitutes with superior performance characteristics.

Q: Can LM833DT replace TL072ID in all applications?

A: No. LM833DT is an Audio Amplifier with different electrical characteristics. While both are dual-circuit 8-SOIC surface mount packages, LM833DT has significantly higher input bias current (300 nA versus 65 pA), lower slew rate (7 V/µs versus 13 V/µs), and different gain bandwidth product (15 MHz versus 5.25 MHz). LM833DT is suitable only for audio applications where these performance differences are acceptable.

Q: What is the difference between Cut Tape (CT) & Digi-Reel® and Tube packaging?

A: Both are surface mount packaging formats for 8-SOIC components. Cut Tape (CT) & Digi-Reel® format supplies components on continuous tape with reel packaging, suitable for automated assembly equipment. Tube packaging supplies components in plastic tubes, typically for manual assembly or lower-volume applications. The electrical performance and pinout are identical; packaging format affects only handling and assembly process.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (TL072IDR, TL072IDT, TL072BIDT, TL072BIYDT, TL072CDT, TL072ACDT, TL082ACDT, LM833DT, MC33172D, MC33172DT) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

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

A: TL072IDR has the highest inventory (35,200 units) and active product status from Texas Instruments, the original manufacturer. TL072CDT has the second-highest inventory (203,200 units) from STMicroelectronics. Both are recommended for new designs requiring long-term supply chain security.

Q: Can TL082ACDT be used instead of TL072IDT?

A: Yes, with package consideration. TL082ACDT is electrically identical to TL072ACDT (both J-FET input, 16 V/µs slew rate, 4 MHz gain bandwidth product, 20 pA input bias current, 3 mV input offset voltage, 0°C to 70°C operating temperature, AEC-Q100 qualified). The primary difference is package designation: TL082ACDT is specified as 8-SO while TL072ACDT is specified as 8-SOIC. Both are physically compatible 8-pin surface mount packages with 0.154" width. Verify PCB footprint compatibility before substitution.
