Engineering Selection Recommendations

Primary Recommendation: TL072CDR

The TL072CDR from Texas Instruments is the direct equivalent to the TL072CDRE4. This part maintains identical electrical specifications (13V/µs slew rate, 5.25 MHz gain bandwidth product, 65 pA input bias current) and operates within the same supply voltage range (10V to 30V) and temperature window (0°C to 70°C). The TL072CDR is in active production status with substantial inventory availability (295,417 pieces), ensuring long-term procurement reliability. Both parts are ROHS3 compliant and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8542.33.0001).

Secondary Recommendations: TL072CDT, TL072ACDT, TL072IDT

These STMicroelectronics variants of the TL072 base product number provide J-FET input architecture with enhanced performance characteristics. The TL072CDT and TL072ACDT operate within the original temperature range (0°C to 70°C), while TL072IDT extends operation to -40°C to 125°C. All three parts feature improved slew rate (16V/µs versus 13V/µs) and expanded supply voltage range (6V to 36V versus 10V to 30V). Input bias current is reduced to 20 pA. These parts are AEC-Q100 qualified and carry automotive-grade designation. Active production status and substantial inventory levels support design implementation.

Alternative Consideration: TL072BIDT and TL072BIYDT

These automotive-qualified variants offer the widest operating temperature range (-40°C to 125°C) and lowest input offset voltage (1 mV versus 3 mV). Inventory availability is lower (1,249 and 3,600 pieces respectively) but remains adequate for production volumes. Selection is appropriate for applications requiring extended temperature performance.

Functional Alternatives: MC33172D, MC33172DT

The MC33172 series from STMicroelectronics provides general-purpose amplifier architecture in identical 8-SOIC packaging. These parts operate across a wider supply voltage range (4V to 44V) and extended temperature span (-40°C to 105°C). However, electrical performance differs significantly: slew rate is reduced to 2V/µs, gain bandwidth product is 2.1 MHz, and supply current is substantially lower (220 µA). Selection of MC33172 variants is appropriate only when the original TL072 electrical specifications are not required and lower power consumption is prioritized.

Not Recommended: LM833DT

The LM833DT audio amplifier operates under fundamentally different electrical specifications (7V/µs slew rate, 15 MHz gain bandwidth product, 300 nA input bias current). While package compatibility exists, the audio amplifier architecture and performance characteristics diverge significantly from the J-FET input topology of the TL072CDRE4. This part is suitable only for applications where audio-specific performance is required and J-FET input characteristics are not essential.

Frequently Asked Questions (FAQ)

Q: Can TL072CDR be used as a direct replacement for TL072CDRE4?

A: Yes. The TL072CDR is the direct equivalent. Both parts share identical electrical specifications, supply voltage range, operating temperature window, and 8-SOIC package configuration. The primary difference is product status: TL072CDRE4 is obsolete while TL072CDR is in active production. Substitution requires no circuit modifications.

Q: What is the difference between TL072CDT and TL072CDR?

A: Both are J-FET input operational amplifiers with the TL072 base product number. The primary differences are manufacturer (STMicroelectronics versus Texas Instruments), packaging format (Cut Tape & Digi-Reel versus standard reel), and enhanced performance specifications in the STMicroelectronics variant (16V/µs slew rate, 6V to 36V supply range, 20 pA input bias current, AEC-Q100 automotive qualification). Electrical compatibility is maintained within the original operating parameters.

Q: Are TL072BIDT and TL072BIYDT interchangeable?

A: Yes, with packaging considerations. Both parts are identical in electrical specifications and performance. TL072BIDT is supplied in Cut Tape & Digi-Reel packaging, while TL072BIYDT is supplied in Tape & Reel format. Selection depends on assembly process requirements. Both are AEC-Q100 qualified automotive-grade devices with -40°C to 125°C operating range.

Q: Can MC33172D replace TL072CDRE4 in all applications?

A: No. While MC33172D shares the 8-SOIC package and dual-circuit configuration, it is a general-purpose amplifier with fundamentally different electrical characteristics. The MC33172D features lower slew rate (2V/µs), lower gain bandwidth product (2.1 MHz), and significantly higher input bias current (20 nA). Substitution is appropriate only when the original TL072 performance specifications are not required and the application can tolerate these electrical differences.

Q: What is the significance of AEC-Q100 qualification on TL072CDT and related variants?

A: AEC-Q100 qualification indicates the part meets automotive industry reliability and quality standards. Parts carrying this designation (TL072CDT, TL072ACDT, TL072IDT, TL072BIDT, TL072BIYDT) are suitable for automotive applications requiring enhanced temperature performance and reliability assurance. Non-automotive applications may use these parts without restriction, but the qualification is not required for general industrial or consumer use.

Q: Why does TL082ACDT have different package designation (8-SO versus 8-SOIC)?

A: TL082ACDT is supplied in 8-SO package format while most other variants use 8-SOIC. Both packages are physically compatible with 0.154" (3.90mm) width and identical pin configuration. The designation difference reflects supplier packaging variation. Electrical specifications and pin assignments remain identical. Substitution is mechanically and electrically valid.

Q: What inventory considerations should guide part selection?

A: TL072CDR offers the highest inventory availability (295,417 pieces), ensuring immediate procurement and long-term supply security. TL072CDT (203,200 pieces) and TL072IDT (55,200 pieces) provide substantial secondary options. MC33172D and MC33172DT offer 100,400 and 45,300 pieces respectively. TL072BIDT and TL072BIYDT have lower availability (1,249 and 3,600 pieces) and should be selected only when specific performance requirements justify potential lead time considerations.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed in this reference maintain ROHS3 compliance status. All parts are also REACH unaffected and carry identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications, ensuring regulatory consistency across substitution options.
