TL082CPWRG4 Equivalent & Substitute Parts

Part Overview

The TL082CPWRG4 is a J-FET input operational amplifier featuring dual circuits in an 8-TSSOP surface mount package, manufactured by Texas Instruments. This device is classified as obsolete, indicating discontinued production and limited availability. The part delivers a 3 MHz gain bandwidth product with 13 V/µs slew rate, suitable for precision analog signal processing applications requiring low input bias current (30 pA) and low input offset voltage (3 mV). Due to obsolete status and finite inventory (1108 pcs), identifying equivalent substitute parts with active production status ensures design continuity and long-term supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TL082CPWRG4 are identified based on strict electrical and mechanical compatibility criteria. All substitute candidates share the following mandatory parameters with the main part:

Mandatory Compatibility Parameters:

• Amplifier Type: J-FET
• Number of Circuits: 2
• Package / Case: 8-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• Voltage - Input Offset: 3 mV
• Current - Supply: 1.4 mA (x2 Channels)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitution Logic: Substitute parts must maintain identical package geometry and mounting technology to ensure PCB compatibility without layout redesign. All candidates retain the dual J-FET amplifier architecture and core electrical specifications. Variations in slew rate, gain bandwidth product, input bias current, output current capability, and supply voltage range are permitted within the TL082 base product family, as these represent performance enhancements or extended operating conditions rather than functional incompatibilities. Product status transition from obsolete to active ensures long-term availability.

Parameter Comparison

Engineering Selection Recommendations

TL082CPWR (Texas Instruments, Active Status)

The TL082CPWR is the direct functional equivalent manufactured by Texas Instruments with active production status. Electrical specifications are identical to the TL082CPWRG4, including slew rate (13 V/µs), gain bandwidth product (3 MHz), and input bias current (30 pA). This part maintains the same supply voltage range (10 V to 30 V) and operating temperature window (0°C to 70°C). Inventory availability (35400 pcs) significantly exceeds the obsolete main part. Packaging differs only in format (Cut Tape & Digi-Reel versus the main part's unspecified packaging), with identical 8-TSSOP case geometry. This substitute is suitable for direct replacement in applications requiring standard commercial-grade operation.

TL082CPT (STMicroelectronics, Active Status, Automotive Grade)

The TL082CPT offers enhanced electrical performance with 16 V/µs slew rate and 4 MHz gain bandwidth product, representing a performance upgrade. Input bias current is reduced to 20 pA, and output current capability increases to 40 mA per channel. Supply voltage range expands to 6 V to 36 V, providing greater flexibility in power supply design. AEC-Q100 automotive qualification and automotive-grade designation indicate suitability for temperature-cycled and vibration-stressed environments. Operating temperature remains 0°C to 70°C. This substitute is appropriate for applications benefiting from enhanced performance specifications and automotive-grade reliability.

TL082IPT (STMicroelectronics, Active Status, Automotive Grade, Extended Temperature)

The TL082IPT combines all performance enhancements of the TL082CPT with extended operating temperature range (-40°C to 105°C), enabling deployment in industrial and harsh environment applications. Electrical specifications match the TL082CPT: 16 V/µs slew rate, 4 MHz gain bandwidth product, 20 pA input bias current, and 40 mA output current per channel. Supply voltage range is 6 V to 36 V. AEC-Q100 qualification and automotive-grade designation apply. This substitute is selected for applications requiring extended temperature operation beyond the standard 0°C to 70°C range.

Frequently Asked Questions (FAQ)

Q1: Can TL082CPWR be used as a direct replacement for TL082CPWRG4 without circuit modification?

A: Yes. The TL082CPWR maintains identical electrical specifications (slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and supply voltage range) and identical 8-TSSOP package geometry. No circuit redesign is required. The only difference is packaging format (Cut Tape & Digi-Reel versus the main part's unspecified format), which does not affect PCB assembly compatibility.

Q2: What are the performance differences between TL082CPWR and TL082CPT/TL082IPT?

A: TL082CPT and TL082IPT offer enhanced performance: slew rate increases from 13 V/µs to 16 V/µs, gain bandwidth product increases from 3 MHz to 4 MHz, input bias current decreases from 30 pA to 20 pA, and output current capability increases from 10 mA to 40 mA per channel. Supply voltage range expands from 10-30 V to 6-36 V. These are performance improvements, not incompatibilities. Existing circuits will function with these substitutes; performance may improve.

Q3: Are TL082CPT and TL082IPT interchangeable?

A: TL082CPT and TL082IPT are electrically identical except for operating temperature range. TL082CPT operates 0°C to 70°C; TL082IPT operates -40°C to 105°C. Both carry AEC-Q100 automotive qualification. Selection depends on application temperature requirements. For standard commercial temperature ranges, TL082CPT is appropriate. For extended or extreme temperature environments, TL082IPT is required.

Q4: Why do TL082CPT and TL082IPT have automotive-grade designation?

A: Automotive-grade designation and AEC-Q100 qualification indicate these parts meet automotive industry reliability and qualification standards, including temperature cycling, vibration, and environmental stress testing. This does not restrict use to automotive applications; these parts are suitable for any application requiring automotive-level reliability.

Q5: Is the 8-TSSOP package identical across all substitute parts?

A: Yes. All substitute parts use 8-TSSOP package with 0.173" width and 4.40mm width specification. PCB footprints are identical. No layout modification is required when substituting between any of these parts.

Q6: What is the significance of the obsolete status for TL082CPWRG4?

A: Obsolete status indicates Texas Instruments has discontinued production of this specific part number. Existing inventory (1108 pcs) will eventually deplete. Active substitute parts (TL082CPWR, TL082CPT, TL082IPT) ensure continued availability for new designs and future production runs. Designs using the obsolete part should transition to an active equivalent.

Q7: Can TL082IPT be used in applications originally designed for TL082CPWRG4?

A: Yes. TL082IPT is fully compatible. It maintains the same package, dual J-FET amplifier architecture, and core electrical specifications. The extended temperature range (-40°C to 105°C) and enhanced performance parameters (higher slew rate, higher gain bandwidth product, lower input bias current, higher output current) represent improvements. Applications operating within the original 0°C to 70°C range will function identically or with improved performance.
