TL082ID Equivalent & Substitute Parts

Part Overview

The TL082ID is a J-FET input operational amplifier manufactured by Texas Instruments, configured as a dual-channel (2 circuit) device in an 8-SOIC surface mount package. This component is classified as obsolete, though 2300 units remain in stock as new original inventory. The TL082ID is designed for applications requiring low input bias current and high input impedance characteristics inherent to J-FET amplifier topology.

Due to its obsolete product status, identifying equivalent and substitute parts is necessary for design continuity, long-term supply chain planning, and new production implementations. Substitute parts must maintain functional compatibility across critical electrical parameters including amplifier type, circuit count, package form factor, and operating specifications.

Engineering Selection Recommendations

For Direct Replacement (J-FET Topology Preservation):

TL082IDR is the primary recommended substitute. This part is manufactured by Texas Instruments, maintains identical J-FET amplifier topology, operates across the required temperature range (-40°C to 85°C), and holds active product status. The TL082IDR is available in Cut Tape and Digi-Reel packaging with 65,100 units in stock. Electrical parameters align closely with the TL082ID, with the exception of reduced output current per channel (10 mA versus 40 mA), which is acceptable for most applications not requiring maximum output drive capability.

ADTL082ARZ and ADTL082ARZ-REEL7 (Analog Devices Inc.) represent enhanced J-FET alternatives with superior performance characteristics. These parts feature improved input bias current (2 pA versus 30 pA), lower input offset voltage (1.5 mV versus 3 mV), higher slew rate (20 V/µs versus 13 V/µs), and extended operating temperature range (-40°C to 125°C). Both variants maintain active product status and are available in substantial quantities (13,125 and 22,215 units respectively). These parts are suitable for applications requiring enhanced precision and wider temperature operation.

For Functional Compatibility (Non-J-FET Alternatives):

MC33072DR2G (onsemi) provides general-purpose amplifier functionality in the 8-SOIC package with active product status. This part maintains the 13 V/µs slew rate and 4.5 MHz gain bandwidth product, operates across -40°C to 85°C, and supports a wider supply voltage range (3V to 44V). Input bias current is significantly higher (100 nA versus 30 pA), making this suitable for applications where J-FET input characteristics are not critical.

MC33172D and MC33172DT (STMicroelectronics) are general-purpose alternatives with active product status and extended temperature operation (-40°C to 105°C). These parts feature lower supply current (220 µA versus 1.4 mA) and wider supply voltage range (4V to 44V), but exhibit reduced slew rate (2 V/µs) and lower gain bandwidth product (2.1 MHz). Selection of these parts requires verification that reduced slew rate and bandwidth do not compromise application performance.

LM833DT (STMicroelectronics) is an audio amplifier variant with active product status, higher gain bandwidth product (15 MHz), and extended temperature range (-40°C to 105°C). This part is suitable only for audio-specific applications and exhibits significantly higher input bias current (300 nA), making it unsuitable for precision low-bias applications.

Compliance and Certification:

All listed substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and REACH Unaffected status, consistent with the TL082ID. All parts are classified under ECCN EAR99 and HTSUS 8542.33.0001.

Frequently Asked Questions (FAQ)

Q: Can TL082IDR be used as a direct replacement for TL082ID?

A: Yes. TL082IDR is a direct substitute manufactured by Texas Instruments with identical J-FET amplifier topology, dual-circuit configuration, and 8-SOIC package. Both parts operate across -40°C to 85°C. The primary difference is reduced output current per channel (10 mA versus 40 mA). Applications not requiring maximum output drive capability can implement TL082IDR without circuit modification. TL082IDR holds active product status, ensuring long-term availability.

Q: What is the difference between TL082IDR and ADTL082ARZ?

A: Both are J-FET dual-channel operational amplifiers in 8-SOIC packages with active product status. ADTL082ARZ (Analog Devices) offers superior electrical performance: input bias current of 2 pA versus 30 pA, input offset voltage of 1.5 mV versus 3 mV, and slew rate of 20 V/µs versus 13 V/µs. ADTL082ARZ also supports extended operating temperature range (-40°C to 125°C versus -40°C to 85°C). Selection depends on application precision requirements and temperature operating envelope.

Q: Can MC33072DR2G replace TL082ID in all applications?

A: MC33072DR2G is a general-purpose amplifier, not a J-FET device. While it maintains compatible slew rate (13 V/µs) and gain bandwidth product (4.5 MHz) in the same 8-SOIC package, input bias current is substantially higher (100 nA versus 30 pA). Applications requiring low input bias current or high input impedance characteristic of J-FET topology require J-FET substitutes such as TL082IDR or ADTL082ARZ. MC33072DR2G is suitable for general-purpose applications where J-FET input characteristics are not essential.

Q: Why is TL082BCD listed as obsolete when TL082IDR is active?

A: TL082BCD is classified as obsolete by the manufacturer despite 888,900 units in stock. TL082IDR, also manufactured by Texas Instruments, maintains active product status and represents the current production equivalent. For new designs and long-term supply chain planning, TL082IDR is the recommended selection to ensure continued availability and manufacturer support.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: Cut Tape (CT) & Digi-Reel (standard for high-volume production), Tape & Reel (TR) for automated assembly, and Tube packaging for lower-volume applications. TL082IDR is available in Cut Tape & Digi-Reel format. ADTL082ARZ-REEL7 is available in Cut Tape & Digi-Reel format. MC33072DR2G is available in Cut Tape & Digi-Reel format. Selection of packaging format depends on production volume and assembly equipment compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, consistent with TL082ID. All parts also maintain MSL Level 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status. These certifications ensure compatibility with modern manufacturing and environmental regulations.

Q: What is the minimum supply voltage requirement for substitute parts?

A: TL082ID requires minimum 10V supply. TL082IDR and TL082BCD maintain this 10V minimum. ADTL082ARZ and ADTL082ARZ-REEL7 operate at lower minimum supply voltage (8V), providing greater flexibility. MC33072DR2G operates at 3V minimum. MC33172D and MC33172DT operate at 4V minimum. LM833DT operates at 5V minimum. Application supply voltage must meet or exceed the substitute part's minimum specification.

Q: Can LM833DT be used in precision instrumentation applications?

A: LM833DT is classified as an audio amplifier and exhibits input bias current of 300 nA, significantly higher than TL082ID (30 pA). This part is not suitable for precision instrumentation applications requiring low input bias current and high input impedance. LM833DT is appropriate only for audio-specific applications where higher input bias current is acceptable.
