TL082CPSRG4 Equivalent & Substitute Parts

Part Overview

The TL082CPSRG4 is a J-FET input operational amplifier manufactured by Texas Instruments, configured as a dual-channel (2 circuit) device in an 8-SO surface mount package. This component is classified as a linear amplifier and is designated as Last Time Buy status, indicating discontinued production with limited inventory availability.

The necessity to identify equivalent and substitute parts for the TL082CPSRG4 arises from its Last Time Buy product status. Organizations requiring this component for ongoing production, maintenance, or new designs must evaluate alternative part numbers that maintain electrical and mechanical compatibility while ensuring continued supply chain access.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL082CPSRG4 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Amplifier Type: J-FET configuration
• Number of Circuits: Dual-channel (2 circuit) topology
• Slew Rate: 13 V/µs
• Gain Bandwidth Product: 3 MHz
• Current - Input Bias: 30 pA
• Voltage - Input Offset: 3 mV
• Current - Supply: 1.4 mA (x2 Channels)
• Current - Output / Channel: 10 mA
• Voltage - Supply Span: 10 V to 30 V
• Operating Temperature: 0°C ~ 70°C minimum
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Secondary Considerations:

• Package dimensions and supplier device package designation
• Product status and supply availability
• Moisture Sensitivity Level compliance

Parts meeting all primary criteria are classified as direct electrical equivalents. Parts with identical electrical specifications but different packaging formats or product status are classified as functional equivalents with packaging or availability distinctions.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalent (Identical Specifications):

The TL082CPSR is a direct electrical equivalent to the TL082CPSRG4. Both parts share identical electrical parameters including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range. Both operate within the 0°C to 70°C temperature range and are packaged in 8-SOIC (0.209", 5.30mm Width) format. Both are designated Last Time Buy status, indicating similar supply constraints. This part is suitable for direct substitution in applications where the original part number is no longer available.

Extended Temperature Range Alternative:

The TL082IDR provides identical electrical specifications to the TL082CPSRG4 with an extended operating temperature range of -40°C to 85°C. This part is currently in Active product status, ensuring continued availability. The TL082IDR is packaged in 8-SOIC (0.154", 3.90mm Width) format with Cut Tape and Digi-Reel® packaging options. The narrower package width (3.90mm versus 5.30mm) requires verification of PCB layout compatibility. This part is recommended for applications requiring extended temperature operation or long-term supply assurance.

Non-Equivalent Alternatives:

The TL082CMX/NOPB and TL082CM/NOPB are not direct electrical equivalents. These parts exhibit higher gain bandwidth product (4 MHz versus 3 MHz), elevated input bias current (50 pA versus 30 pA), increased input offset voltage (5 mV versus 3 mV), higher supply current (3.6 mA versus 1.4 mA per channel), and increased output current (17 mA versus 10 mA per channel). Additionally, these parts operate with a fixed supply voltage span of 36 V, differing from the 10 V to 30 V range of the TL082CPSRG4. These parts are classified as Active status with improved availability. Substitution is permissible only in applications where the elevated electrical parameters do not create circuit performance degradation or power dissipation concerns.

Frequently Asked Questions (FAQ)

Q: Can the TL082CPSR be used as a direct replacement for the TL082CPSRG4?

A: Yes. The TL082CPSR is electrically identical to the TL082CPSRG4 across all specified parameters. Both parts are Last Time Buy status. The primary distinction is inventory availability, with the TL082CPSR currently showing higher stock levels (2300 Pcs versus 920 Pcs).

Q: What is the primary advantage of selecting the TL082IDR over the TL082CPSRG4?

A: The TL082IDR offers extended operating temperature range (-40°C to 85°C versus 0°C to 70°C) and Active product status, ensuring long-term supply availability. Electrical specifications are identical. PCB layout verification is required due to package width reduction from 5.30mm to 3.90mm.

Q: Are the TL082CMX/NOPB and TL082CM/NOPB suitable substitutes?

A: These parts are not direct electrical equivalents. They exhibit higher gain bandwidth product, input bias current, input offset voltage, supply current, and output current specifications. Substitution is permissible only when circuit design tolerates these elevated parameters without performance degradation.

Q: What packaging format differences exist among the substitute parts?

A: The TL082CPSRG4 and TL082CPSR are supplied in Tape & Reel format. The TL082IDR is available in Cut Tape and Digi-Reel® formats. The TL082CM/NOPB is supplied in Tube format. Packaging selection depends on assembly process requirements and inventory management practices.

Q: Does package size variation affect circuit compatibility?

A: The TL082IDR uses a narrower 8-SOIC package (3.90mm width) compared to the TL082CPSRG4 (5.30mm width). Pin pitch and electrical connections remain identical. PCB footprint and layout spacing must be verified to accommodate the reduced package width.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the environmental and regulatory status of the TL082CPSRG4.

Q: What is the recommended substitution priority?

A: Priority 1: TL082CPSR (identical specifications and package). Priority 2: TL082IDR (identical electrical specifications, extended temperature range, Active status, requires package width verification). Priority 3: TL082CMX/NOPB or TL082CM/NOPB (only when elevated electrical parameters are acceptable).
