TL082CPSR Equivalent & Substitute Parts Reference

Part Overview

The TL082CPSR 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 a Linear Amplifier and is currently designated as Last Time Buy, indicating discontinued production with limited inventory availability.

The TL082CPSR operates across a supply voltage range of 10V to 30V with an operating temperature range of 0°C to 70°C. Due to its Last Time Buy status, identification of equivalent substitute parts is necessary for design continuity and long-term component sourcing strategy.

• Voltage - Supply Span: 10V to 30V operating range
• Mounting Type: Surface Mount
• Package Category: 8-SOIC form factor

Substitute Parts Identified:

Group 1 - Direct Functional Equivalent (Active Status):

• TL082IDR: Active product status with extended operating temperature range (-40°C to 85°C), identical electrical specifications, different package width (0.154" vs 0.209"), Cut Tape & Digi-Reel packaging

Group 2 - Functional Equivalent with Parameter Variations (Active Status):

• TL082CMX/NOPB: Active product status, identical slew rate, elevated gain bandwidth product (4 MHz), increased input bias current (50 pA), increased input offset voltage (5 mV), increased supply current (3.6 mA per 2 channels), increased output current per channel (17 mA), fixed supply voltage (36V), Tape & Reel packaging

Parameter Comparison

Engineering Selection Recommendations

TL082IDR Selection Criteria: The TL082IDR is the primary recommended substitute for the TL082CPSR. This part maintains identical electrical performance across all critical parameters including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current specifications. The TL082IDR offers extended operating temperature range (-40°C to 85°C) compared to the TL082CPSR (0°C to 70°C), providing enhanced thermal performance margin. Active product status ensures long-term availability and supply continuity. The primary design consideration is package width variation: TL082IDR uses 0.154" width (3.90mm) versus TL082CPSR 0.209" width (5.30mm). PCB layout verification is required to confirm compatibility with existing footprints. Cut Tape & Digi-Reel packaging accommodates both automated assembly and manual component handling.

TL082CMX/NOPB and TL082CM/NOPB Selection Criteria: These parts are functionally equivalent substitutes with measurable parameter deviations. Both maintain J-FET amplifier topology and dual-channel configuration. Electrical performance differs in four parameters: gain bandwidth product (4 MHz vs 3 MHz), input bias current (50 pA vs 30 pA), input offset voltage (5 mV vs 3 mV), and supply current (3.6 mA vs 1.4 mA per 2 channels). Output current per channel is increased to 17 mA. Supply voltage operation is fixed at 36V, eliminating the flexible 10V to 30V range of the TL082CPSR. These parts are suitable for applications where the elevated electrical specifications do not create circuit performance degradation. Active product status ensures availability. Selection between TL082CMX/NOPB (Tape & Reel) and TL082CM/NOPB (Tube) depends on assembly process requirements.

Compliance and Certification: All substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) rating, matching the TL082CPSR environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q1: Can TL082IDR directly replace TL082CPSR in existing PCB designs?

A: Electrical substitution is direct. Physical substitution requires PCB layout verification due to package width difference (0.154" vs 0.209"). The 8-SOIC pin configuration remains identical. Footprint compatibility must be confirmed before production implementation.

Q2: What is the primary advantage of TL082IDR over TL082CPSR?

A: TL082IDR offers active product status with guaranteed long-term availability, whereas TL082CPSR is Last Time Buy with limited inventory. TL082IDR provides extended operating temperature range (-40°C to 85°C vs 0°C to 70°C), enabling deployment in wider environmental conditions.

Q3: Are TL082CMX/NOPB and TL082CM/NOPB suitable for direct substitution?

A: These parts are functionally equivalent with parameter variations. Substitution is valid only if circuit design tolerates increased input bias current (50 pA vs 30 pA), input offset voltage (5 mV vs 3 mV), and supply current (3.6 mA vs 1.4 mA per 2 channels). Fixed 36V supply voltage operation differs from the flexible 10V to 30V range. Application-specific circuit analysis is required.

Q4: What packaging options are available for substitute parts?

A: TL082IDR is supplied in Cut Tape & Digi-Reel format. TL082CMX/NOPB is supplied in Tape & Reel. TL082CM/NOPB is supplied in Tube. Selection depends on assembly process: automated pick-and-place systems typically use tape formats, while manual assembly may use tube packaging.

Q5: Do all substitute parts meet RoHS and environmental compliance requirements?

A: Yes. All substitute parts (TL082IDR, TL082CMX/NOPB, TL082CM/NOPB) are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching TL082CPSR compliance status.

Q6: What is the primary difference between TL082CMX/NOPB and TL082CM/NOPB?

A: Electrical specifications are identical. The difference is packaging format: TL082CMX/NOPB uses Tape & Reel, while TL082CM/NOPB uses Tube. Selection is based on assembly equipment compatibility and handling requirements.

Q7: Is the TL082CPSR package width difference critical for substitution?

A: Package width variation (0.209" vs 0.154") affects PCB footprint compatibility. Existing designs using TL082CPSR may require footprint modification to accommodate TL082IDR. Verify PCB layout spacing and component placement before substitution.
