Engineering Selection Recommendations

Tier 1 - Direct Electrical Equivalent (Recommended for Drop-In Replacement):

TL082CDR (Texas Instruments) is the primary substitute for TL082CDRG4. This part maintains identical electrical specifications across all critical parameters: 13 V/µs slew rate, 3 MHz gain bandwidth product, 30 pA input bias current, and 3 mV input offset voltage. The supply voltage range (10 V to 30 V) and operating temperature (0°C to 70°C) are identical. TL082CDR is in active production status, ensuring long-term availability. Both parts are ROHS3 compliant and carry MSL 1 rating. The primary difference is packaging format: TL082CDR is supplied in Cut Tape (CT) & Digi-Reel® format, matching the original part's packaging specification.

Tier 2 - Enhanced Performance Substitutes (Superior Specifications):

TL082BCDT, TL082ACDT, and TL082CDT (all STMicroelectronics) offer improved electrical performance while maintaining J-FET amplifier topology and dual-circuit configuration. These parts feature 16 V/µs slew rate (23% improvement), 4 MHz gain bandwidth product (33% improvement), and reduced input bias current (20 pA versus 30 pA). Input offset voltage remains at 3 mV or better. Output current capability increases to 40 mA per channel (4× improvement). Supply voltage range expands to 6 V minimum and 36 V maximum, providing greater flexibility. All three parts are in active production with AEC-Q100 automotive qualification. Operating temperature range is 0°C to 70°C, matching the original specification.

Tier 3 - Extended Temperature Range Alternatives:

TL082AIYDT and TL082BIYDT (STMicroelectronics) provide identical electrical performance to Tier 2 parts with extended operating temperature range (-40°C to 105°C). These parts are suitable for applications requiring operation beyond the standard 0°C to 70°C range. Both carry AEC-Q100 automotive qualification and are in active production status.

Tier 4 - Functional Alternative (Different Amplifier Type):

LM833DT (STMicroelectronics) is an audio amplifier with dual circuits in 8-SOIC package. This part differs fundamentally in amplifier type (audio versus J-FET) and input bias current (300 nA versus 30 pA). LM833DT is suitable only for applications where higher input bias current is acceptable and audio-grade performance is sufficient. This part is not recommended as a direct substitute for precision analog applications requiring J-FET input characteristics.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and 8-SOIC surface mount package compatibility with the original TL082CDRG4.

Frequently Asked Questions (FAQ)

Q1: Can TL082CDR be used as a direct replacement for TL082CDRG4?

A: Yes. TL082CDR is electrically identical to TL082CDRG4 across all specified parameters: slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range. Both operate at 0°C to 70°C. The primary advantage of TL082CDR is active production status, ensuring availability for new procurement. Packaging format (Cut Tape & Digi-Reel®) is identical.

Q2: What are the advantages of using TL082BCDT or TL082ACDT instead of TL082CDR?

A: TL082BCDT and TL082ACDT offer superior performance specifications: 16 V/µs slew rate (versus 13 V/µs), 4 MHz gain bandwidth product (versus 3 MHz), lower input bias current (20 pA versus 30 pA), and higher output current capability (40 mA versus 10 mA per channel). Supply voltage range expands to 6 V minimum and 36 V maximum. These improvements provide better signal fidelity, lower input loading, and greater output drive capability. Both parts carry AEC-Q100 automotive qualification and are in active production.

Q3: Is LM833DT a suitable substitute for TL082CDRG4?

A: LM833DT is not recommended as a direct substitute. While both are dual-circuit operational amplifiers in 8-SOIC packages, LM833DT is an audio amplifier with fundamentally different input characteristics. Input bias current is 300 nA (versus 30 pA for TL082CDRG4), making it unsuitable for precision analog applications requiring low input loading. LM833DT is appropriate only for audio applications where higher input bias current is acceptable.

Q4: What is the difference between TL082AIYDT and TL082BCDT?

A: Both parts have identical electrical specifications and AEC-Q100 automotive qualification. The primary difference is operating temperature range: TL082AIYDT operates from -40°C to 105°C, while TL082BCDT operates from 0°C to 70°C. TL082AIYDT is suitable for applications requiring extended temperature operation. Additionally, TL082AIYDT is supplied in Tape & Reel (TR) format, while TL082BCDT is supplied in Cut Tape (CT) & Digi-Reel® format.

Q5: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (TL082CDR, TL082BCD, TL082CMX/NOPB, LM833DT, TL072CDT, TL082ACDT, TL082AIYDT, TL082BCDT, TL082BIYDT, and TL082CDT) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original TL082CDRG4 specification.

Q6: Can TL082CMX/NOPB be used as a substitute?

A: TL082CMX/NOPB is electrically compatible but with performance trade-offs. This part features identical slew rate (13 V/µs) and similar gain bandwidth product (4 MHz). However, input bias current increases to 50 pA (versus 30 pA), input offset voltage increases to 5 mV (versus 3 mV), and supply current increases to 3.6 mA per channel (versus 1.4 mA). Supply voltage range is fixed at 36 V (versus 10 V to 30 V for TL082CDRG4). TL082CMX/NOPB is suitable only for applications where these parameter variations are acceptable.

Q7: What packaging formats are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: Cut Tape (CT) & Digi-Reel®, Tape & Reel (TR), Cut Tape (CT), and Tube. Cut Tape (CT) & Digi-Reel® format matches the original TL082CDRG4 specification and is recommended for standard procurement. Tape & Reel (TR) format is suitable for high-volume automated assembly. Selection depends on production volume and assembly equipment compatibility.

Q8: Do substitute parts maintain the same pin configuration?

A: Yes. All substitute parts maintain the 8-SOIC (0.154", 3.90 mm width) package specification, ensuring identical pin configuration and PCB footprint compatibility with TL082CDRG4. Surface mount assembly equipment and PCB layouts require no modification.
