Substitution of the TL082ACDRE4 is determined by strict alignment of electrical and mechanical parameters within the 8-SOIC package form factor. The critical substitution criteria are:

Primary Compatibility Parameters:

Package / Case: 8-SOIC (0.154", 3.90mm Width)
Mounting Type: Surface Mount
Number of Circuits: 2
Amplifier Type: J-FET (preferred) or functionally equivalent general-purpose amplifier
Voltage - Supply Span: Minimum 10V to Maximum 30V overlap required
Operating Temperature: Minimum 0°C capability required

Secondary Electrical Parameters:

Slew Rate: 13V/µs or greater
Gain Bandwidth Product: 3 MHz or greater
Current - Input Bias: 30 pA or lower
Voltage - Input Offset: 3 mV or lower
Current - Supply: 1.4 mA (x2 Channels) or lower
Current - Output / Channel: 10 mA or greater

Substitute parts are grouped into two categories: Direct J-FET Equivalents (TL082ACDR, TL082BCD, TL082CMX/NOPB) and Enhanced Performance Alternatives (AD8512ARZ, AD8512ARZ-REEL, ADTL082ARZ-REEL7, MC33072DR2G, MC33172D, MC33172DT, LM833DT).

Engineering Selection Recommendations

Direct Replacement (Recommended for Obsolete Part Mitigation):

TL082ACDR is the primary recommended substitute. This part maintains identical electrical specifications to the TL082ACDRE4 while holding Active product status from Texas Instruments. Both devices are ROHS3 compliant, MSL Level 1, and packaged in 8-SOIC form factor. The TL082ACDR is available in Cut Tape (CT) & Digi-Reel® packaging with 100,098 pieces in stock, providing superior procurement continuity compared to the obsolete TL082ACDRE4.

Secondary Direct Equivalent:

TL082BCD offers identical electrical performance with marginally improved input offset voltage (2 mV versus 3 mV). However, this part is classified as Obsolete, limiting its long-term availability despite current inventory of 888,900 pieces.

Enhanced Performance Alternatives (Active Status):

AD8512ARZ and AD8512ARZ-REEL provide superior electrical performance with 20V/µs slew rate, 8 MHz gain bandwidth product, and extended operating temperature range (-40°C to 125°C). These Analog Devices J-FET amplifiers maintain the 10V to 30V supply voltage compatibility and 8-SOIC package form factor. Input bias current is reduced to 25 pA, and input offset voltage is improved to 100 µV. Output current capability increases to 70 mA per channel.

ADTL082ARZ-REEL7 represents the highest performance J-FET option with 2 pA input bias current, 1.5 mV input offset voltage, and extended supply voltage range (8V to 36V). This part is suitable for applications requiring ultra-low input bias current and superior precision.

General Purpose Alternatives:

MC33072DR2G (onsemi) and MC33172D/MC33172DT (STMicroelectronics) are general-purpose amplifiers with Active status. MC33072DR2G maintains 13V/µs slew rate and 4.5 MHz gain bandwidth product with extended supply voltage range (3V to 44V). MC33172D and MC33172DT feature lower supply current (220 µA) but reduced slew rate (2V/µs) and gain bandwidth product (2.1 MHz).

Audio Amplifier Alternative:

LM833DT is classified as an audio amplifier with 15 MHz gain bandwidth product and 7V/µs slew rate. This part is suitable only for audio-specific applications and is not recommended for general-purpose analog signal processing due to higher input bias current (300 nA) and different amplifier architecture.

Compliance and Certification:

All recommended substitute parts maintain ROHS3 compliance, MSL Level 1 moisture sensitivity, and EAR99 export classification. REACH status is unaffected for all listed alternatives.

Frequently Asked Questions (FAQ)

Q: Can TL082ACDR be used as a direct drop-in replacement for TL082ACDRE4?

A: Yes. TL082ACDR is electrically and mechanically identical to TL082ACDRE4. Both devices feature identical slew rate (13V/µs), gain bandwidth product (3 MHz), input bias current (30 pA), input offset voltage (3 mV), supply current (1.4 mA per channel), output current (10 mA), and supply voltage range (10V to 30V). The primary difference is product status: TL082ACDR is Active while TL082ACDRE4 is Obsolete. Both are packaged in 8-SOIC form factor with identical pinout and electrical characteristics.

Q: What is the key difference between J-FET amplifiers and general-purpose amplifiers in this list?

A: J-FET amplifiers (TL082 series, AD8512, ADTL082) feature extremely low input bias current (2 to 50 pA range) due to J-FET input stage architecture. General-purpose amplifiers (MC33072, MC33172) use bipolar input stages with higher input bias current (20 to 100 nA range). J-FET amplifiers are preferred for high-impedance signal sources and precision measurement applications. General-purpose amplifiers offer lower input offset voltage and wider supply voltage ranges.

Q: Can MC33172D replace TL082ACDRE4 in all applications?

A: No. While MC33172D is packaged in 8-SOIC and operates within the 10V to 30V supply range, it exhibits significantly reduced slew rate (2V/µs versus 13V/µs) and lower gain bandwidth product (2.1 MHz versus 3 MHz). MC33172D is suitable only for low-frequency applications where slew rate and bandwidth are not critical. Additionally, MC33172D features higher input bias current (20 nA versus 30 pA), making it unsuitable for high-impedance signal conditioning.

Q: What is the advantage of AD8512ARZ over TL082ACDR?

A: AD8512ARZ provides enhanced electrical performance: 20V/µs slew rate (versus 13V/µs), 8 MHz gain bandwidth product (versus 3 MHz), 25 pA input bias current (versus 30 pA), and 100 µV input offset voltage (versus 3 mV). AD8512ARZ also features extended operating temperature range (-40°C to 125°C versus 0°C to 70°C) and higher output current capability (70 mA versus 10 mA). These improvements make AD8512ARZ suitable for higher-speed signal processing and wider temperature applications. However, AD8512ARZ exhibits higher supply current (2.2 mA versus 1.4 mA).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed in this document are ROHS3 compliant with MSL Level 1 moisture sensitivity rating. All parts are classified as EAR99 for export purposes and are REACH unaffected.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: Cut Tape (CT) & Digi-Reel® (TL082ACDR, AD8512ARZ-REEL, ADTL082ARZ-REEL7, MC33072DR2G, MC33172DT, LM833DT), Tape & Reel (TR) (TL082CMX/NOPB), and Tube (TL082BCD, AD8512ARZ, MC33172D). All maintain identical 8-SOIC form factor and pinout. Selection of packaging format depends on procurement volume and assembly process requirements.

Q: Is TL082CMX/NOPB suitable as a substitute?

A: TL082CMX/NOPB is a J-FET amplifier with identical slew rate (13V/µs) but exhibits degraded electrical specifications: input bias current of 50 pA (versus 30 pA), input offset voltage of 5 mV (versus 3 mV), and higher supply current (3.6 mA versus 1.4 mA). Additionally, TL082CMX/NOPB operates at fixed 36V supply voltage rather than the 10V to 30V range of TL082ACDRE4. This part is not recommended as a substitute.

Q: Can ADTL082ARZ-REEL7 be used in applications requiring 0°C to 70°C operating temperature?

A: Yes. ADTL082ARZ-REEL7 operates across -40°C to 125°C temperature range, which encompasses the 0°C to 70°C requirement of TL082ACDRE4. ADTL082ARZ-REEL7 is suitable for this application with superior performance characteristics including 2 pA input bias current and 1.5 mV input offset voltage.
