TL082CPW Equivalent & Substitute Parts

Part Overview

The TL082CPW 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 product status, though 1,797 pieces remain available in original inventory. The TL082CPW operates across a supply voltage range of 10V to 30V with a slew rate of 13V/µs and gain bandwidth product of 3 MHz, making it suitable for precision analog signal processing applications requiring low input bias current and low input offset voltage characteristics.

Engineering Selection Recommendations

TL082CPWR Selection: TL082CPWR is the primary recommended substitute for TL082CPW applications. This part maintains identical electrical specifications across all critical parameters: slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current. Both devices operate within the 0°C to 70°C temperature range and utilize the same 8-TSSOP package footprint. TL082CPWR holds active product status with significantly higher inventory availability (35,400 pieces), ensuring long-term supply continuity. Packaging format differs (Cut Tape & Digi-Reel® versus Tube), but this does not affect electrical or mechanical compatibility. ROHS3 compliance and MSL Level 1 rating are maintained.

TL082CM/NOPB Selection: TL082CM/NOPB is a functional substitute when package footprint flexibility exists. This part shares the same base product family and J-FET dual-circuit architecture. The 8-SOIC package (0.154", 3.90mm Width) differs from the 8-TSSOP footprint, requiring PCB layout modification. Electrical parameters show variations: supply current increases to 3.6mA, output current per channel increases to 17mA, and input bias current increases to 50pA. Gain bandwidth product increases to 4 MHz. Active product status with 2,200 pieces in inventory. Selection requires confirmation that the 8-SOIC footprint accommodates board design constraints and that the increased supply current and modified electrical characteristics align with circuit requirements.

TL082CPT and TL082IPT Selection: Both STMicroelectronics variants (TL082CPT and TL082IPT) are suitable substitutes when enhanced electrical performance and extended supply voltage range are compatible with application requirements. Both parts maintain the 8-TSSOP package footprint, enabling direct PCB compatibility. Enhanced specifications include 16V/µs slew rate (versus 13V/µs), 4 MHz gain bandwidth product (versus 3 MHz), lower input bias current (20pA versus 30pA), and significantly higher output current per channel (40mA versus 10mA). Supply voltage range extends to 6V minimum and 36V maximum, providing broader operational flexibility. Both parts carry AEC-Q100 automotive qualification. TL082IPT extends operating temperature to -40°C to 105°C, suitable for extended temperature applications. TL082CPT maintains 0°C to 70°C range. Active product status with 2,200 and 5,350 pieces in inventory respectively. Selection of these variants is appropriate when circuit design benefits from enhanced performance specifications and automotive-grade reliability.

Frequently Asked Questions (FAQ)

Q: Can TL082CPWR directly replace TL082CPW without PCB modification?

A: Yes. TL082CPWR maintains identical electrical specifications and uses the same 8-TSSOP package footprint as TL082CPW. PCB layout and schematic connections require no modification. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tube), which does not affect component functionality or mounting compatibility.

Q: What are the key differences between TL082CPWR and TL082CM/NOPB?

A: The primary difference is package type. TL082CPWR uses 8-TSSOP (0.173", 4.40mm Width), while TL082CM/NOPB uses 8-SOIC (0.154", 3.90mm Width). Electrical specifications also differ: TL082CM/NOPB has higher supply current (3.6mA versus 1.4mA), higher output current per channel (17mA versus 10mA), higher input bias current (50pA versus 30pA), and higher input offset voltage (5mV versus 3mV). TL082CM/NOPB requires PCB layout redesign and is suitable only when these electrical parameter changes are acceptable.

Q: Why would I select TL082CPT or TL082IPT over TL082CPWR?

A: TL082CPT and TL082IPT offer enhanced electrical performance: faster slew rate (16V/µs versus 13V/µs), higher gain bandwidth product (4 MHz versus 3 MHz), lower input bias current (20pA versus 30pA), and significantly higher output current per channel (40mA versus 10mA). Extended supply voltage range (6V to 36V versus 10V to 30V) provides broader operational flexibility. Both carry AEC-Q100 automotive qualification. TL082IPT additionally extends operating temperature to -40°C to 105°C. Selection depends on whether circuit design requires these enhanced specifications and automotive-grade reliability.

Q: Is TL082IPT suitable for extended temperature applications?

A: Yes. TL082IPT operates across -40°C to 105°C, compared to TL082CPW's 0°C to 70°C range. This extended temperature capability makes TL082IPT suitable for automotive and industrial applications requiring operation beyond standard commercial temperature limits. All other electrical and mechanical specifications remain compatible with TL082CPW requirements within the 0°C to 70°C overlap range.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TL082CPWR, TL082CM/NOPB, TL082CPT, and TL082IPT are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, matching TL082CPW compliance status.

Q: What is the inventory status of each substitute part?

A: TL082CPWR has the highest availability with 35,400 pieces in stock. TL082CPT and TL082CM/NOPB each have 2,200 pieces. TL082IPT has 5,350 pieces. TL082CPW (obsolete) has 1,797 pieces remaining. For long-term supply assurance, TL082CPWR is the preferred choice due to superior inventory levels and active product status.

Q: Can I use TL082CM/NOPB as a direct replacement without design changes?

A: No. TL082CM/NOPB requires PCB layout modification due to different package footprint (8-SOIC versus 8-TSSOP). Additionally, electrical parameter changes (higher supply current, higher output current, higher input bias current, higher input offset voltage) must be evaluated for circuit compatibility. Design review is necessary before implementation.

Q: What certifications do the STMicroelectronics variants carry?

A: Both TL082CPT and TL082IPT carry AEC-Q100 automotive qualification, indicating compliance with automotive industry reliability and quality standards. This qualification is not present in the Texas Instruments variants (TL082CPW and TL082CPWR).
