Engineering Selection Recommendations

Direct Equivalents (Recommended for Immediate Substitution):

The TL072BCD and TL072BCDR are direct manufacturer equivalents of the TL072BCDE4. Both parts maintain identical electrical specifications across all critical parameters including slew rate, gain bandwidth product, input bias current, and supply voltage range. The TL072BCDR is recommended as the primary substitute due to its active product status and higher inventory availability (7194 units). The TL072BCD remains available as a secondary option with 1500 units in stock. Both parts are ROHS3 compliant and carry MSL Level 1 rating.

J-FET Amplifier Alternatives (Analog Devices AD8682 Series):

The AD8682ARZ, AD8682ARZ-REEL, and AD8682ARZ-REEL7 are J-FET amplifiers from Analog Devices that maintain the same amplifier type and package configuration. These parts feature improved input bias current (6 pA versus 65 pA) and lower input offset voltage (350 µV versus 2 mV). However, they exhibit reduced slew rate (9V/µs versus 13V/µs) and lower gain bandwidth product (3.5 MHz versus 5.25 MHz). All three variants are active products with ROHS3 compliance and extended operating temperature range (-40°C to 85°C). Selection among the three AD8682 variants depends on packaging requirements: AD8682ARZ for tube packaging, AD8682ARZ-REEL for standard reel format, and AD8682ARZ-REEL7 for tape and reel format.

General Purpose and Specialized Amplifier Alternatives:

The AS358AMTR-E1 (Diodes Incorporated), LM258D (STMicroelectronics), MC33072ADR2G (onsemi), and LT1352IS8#TR (Analog Devices) are functional alternatives that share the 8-SOIC package and dual-circuit configuration but differ in amplifier type and electrical characteristics. These parts are suitable for applications where the specific J-FET characteristics of the TL072BCDE4 are not critical. The LM833DT is an audio-optimized amplifier with higher gain bandwidth product (15 MHz) and slew rate (7V/µs), suitable for audio signal processing applications. All alternative parts are active products with ROHS3 compliance.

Selection Criteria:

For applications requiring preservation of the original TL072BCDE4 electrical performance, select TL072BCDR as the primary substitute. For applications tolerant of improved input bias current and offset voltage characteristics, select from the AD8682 series. For cost-optimized or extended temperature range applications, evaluate the general purpose alternatives based on specific circuit requirements and performance margins.

Frequently Asked Questions (FAQ)

Q: Can the TL072BCDR be used as a direct replacement for the TL072BCDE4?

A: Yes. The TL072BCDR is a direct manufacturer equivalent with identical electrical specifications. The only differences are packaging format (Cut Tape & Digi-Reel versus the original format) and product status (Active versus Obsolete). No circuit modifications are required.

Q: What is the primary difference between the TL072BCDE4 and the AD8682ARZ?

A: Both are J-FET amplifiers in 8-SOIC packages with two circuits. The AD8682ARZ features superior input bias current (6 pA versus 65 pA) and lower input offset voltage (350 µV versus 2 mV). However, it has lower slew rate (9V/µs versus 13V/µs) and reduced gain bandwidth product (3.5 MHz versus 5.25 MHz). The AD8682ARZ also supports extended operating temperature range (-40°C to 85°C versus 0°C to 70°C).

Q: Are the AS358AMTR-E1 and LM258D suitable replacements for the TL072BCDE4?

A: These parts share the 8-SOIC package and dual-circuit configuration but are General Purpose amplifiers rather than J-FET types. They are suitable only for applications where J-FET input characteristics are not essential. They feature higher input bias current (20 nA versus 65 pA) and different frequency response characteristics. Circuit-level evaluation is required before substitution.

Q: What packaging options are available for the AD8682 J-FET amplifier?

A: Three packaging variants are available: AD8682ARZ (Tube), AD8682ARZ-REEL (standard reel format), and AD8682ARZ-REEL7 (Tape & Reel format). All three variants have identical electrical specifications and differ only in packaging and handling format.

Q: Is the LM833DT compatible with the TL072BCDE4 in audio applications?

A: The LM833DT is an audio-optimized amplifier with higher gain bandwidth product (15 MHz) and slew rate (7V/µs) compared to the TL072BCDE4 (5.25 MHz and 13V/µs respectively). It is suitable for audio signal processing where higher bandwidth is beneficial. However, it has higher input bias current (300 nA versus 65 pA) and different input offset voltage (300 µV versus 2 mV). Circuit evaluation is required.

Q: What is the significance of the product status (Obsolete versus Active)?

A: Obsolete products are no longer manufactured and have limited availability. Active products are in current production with ongoing supply. For new designs or long-term production, active products such as TL072BCDR, AD8682 series, and other alternatives are recommended to ensure component availability and supply chain continuity.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All substitute parts listed in this reference are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the TL072BCDE4.

Q: What is the difference between the three AD8682 packaging variants?

A: AD8682ARZ is supplied in tube packaging for manual handling. AD8682ARZ-REEL is supplied on standard reel format for automated assembly. AD8682ARZ-REEL7 is supplied on tape and reel format optimized for high-speed pick-and-place equipment. All three have identical electrical specifications and differ only in packaging format and handling method.

Q: Can the MC33072ADR2G replace the TL072BCDE4 in precision analog circuits?

A: The MC33072ADR2G is a General Purpose amplifier with different input bias current (100 nA versus 65 pA) and input offset voltage (500 µV versus 2 mV). It features higher slew rate (13V/µs, matching the TL072BCDE4) and extended supply voltage range (3V to 44V). It is suitable for applications where precision input characteristics are not critical. Circuit-level evaluation is required for precision applications.

Q: What is the operating temperature range difference between the TL072BCDE4 and its substitutes?

A: The TL072BCDE4 operates from 0°C to 70°C. Most active substitutes (AD8682 series, AS358AMTR-E1, LM258D, LM833DT, MC33072ADR2G) operate from -40°C to 85°C, providing extended low-temperature capability. The LT1352IS8#TR also operates from -40°C to 85°C. For applications requiring the original 0°C to 70°C range, verify that the substitute part's extended range does not introduce design complications.
