TL082CPS Equivalent & Substitute Parts

Part Overview

The TL082CPS is a J-FET input operational amplifier featuring two independent circuits in a push-pull output configuration. Manufactured by Texas Instruments, this device is classified as a linear amplifier and is designated as Last Time Buy, indicating discontinued production with limited remaining inventory. The TL082CPS is designed for applications requiring low input bias current and stable gain-bandwidth characteristics across a wide supply voltage range. Identification of equivalent substitute parts is necessary due to the Last Time Buy status and finite stock availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL082CPS is determined by equivalence across the following critical parameters:

Core Functional Parameters:

• Amplifier Type: J-FET input architecture
• Number of Circuits: Dual-channel configuration
• Slew Rate: 13 V/µs
• Gain Bandwidth Product: 3 MHz
• Input Bias Current: 30 pA
• Input Offset Voltage: 3 mV
• Supply Current: 1.4 mA
• Supply Voltage Range: 10 V to 30 V

Physical & Environmental Parameters:

• Mounting Type: Surface Mount
• Package Type: 8-SOIC
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity: MSL 1

The TL082IDR qualifies as a direct substitute based on matching all core functional parameters and environmental compliance requirements. Both devices share identical electrical specifications and are manufactured by Texas Instruments under the same base product number (TL082).

Parameter Comparison

*Both devices use 8-SOIC package format. Physical dimensions differ slightly; both are compatible with standard 8-SOIC PCB footprints.

Engineering Selection Recommendations

Primary Substitute: TL082IDR

The TL082IDR is the manufacturer-recommended substitute for the TL082CPS. This substitution is supported by:

1. Electrical Equivalence: All functional parameters match exactly, including slew rate, gain-bandwidth product, input bias current, input offset voltage, and supply current specifications.

2. Supply Voltage Compatibility: Both devices operate across the identical 10 V to 30 V supply range, ensuring direct compatibility in existing circuit designs.

3. Compliance & Certification: Both parts maintain ROHS3 compliance and MSL 1 moisture sensitivity rating, meeting environmental and reliability standards.

4. Product Status Advantage: The TL082IDR carries Active product status with 65,100 units in stock, providing long-term availability compared to the Last Time Buy status of the TL082CPS.

5. Operating Temperature Consideration: The TL082IDR supports an extended operating temperature range (-40°C ~ 85°C) compared to the TL082CPS (0°C ~ 70°C). Applications operating within the TL082CPS temperature window will function identically; applications requiring extended low-temperature operation benefit from the TL082IDR specification.

6. Package Compatibility: Both devices use 8-SOIC surface-mount packaging. Standard PCB footprints accommodate both variants without design modification.

Frequently Asked Questions (FAQ)

Q: Can the TL082IDR directly replace the TL082CPS in existing designs?

A: Yes. The TL082IDR is electrically and functionally equivalent to the TL082CPS across all specified parameters. No circuit modifications are required for substitution.

Q: Are there differences in package dimensions between these parts?

A: Both devices use 8-SOIC packaging. The TL082CPS specifies 0.209" (5.30mm) width, while the TL082IDR specifies 0.154" (3.90mm) width. Both conform to standard 8-SOIC footprint specifications and are compatible with existing PCB layouts designed for 8-SOIC components.

Q: What is the significance of the Last Time Buy status for the TL082CPS?

A: Last Time Buy indicates that Texas Instruments has discontinued production of the TL082CPS. Current inventory (4,135 units) represents the final available stock. The TL082IDR, with Active status and 65,100 units in inventory, provides assured long-term availability.

Q: Do the operating temperature ranges affect substitution suitability?

A: The TL082CPS operates from 0°C to 70°C, while the TL082IDR operates from -40°C to 85°C. For applications within the 0°C to 70°C window, both parts perform identically. The TL082IDR provides additional capability for extended temperature applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the TL082CPS and TL082IDR are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting current environmental and reliability standards.

Q: What is the base product number relationship?

A: Both the TL082CPS and TL082IDR are variants of the TL082 base product family manufactured by Texas Instruments. The suffix designations (CPS and IDR) indicate specific packaging and temperature grade configurations within this family.
