Engineering Selection Recommendations

For Active Product Status Requirement:

Select TL082CMX/NOPB, TL082ACDR, TL082BCDR, TL082CDR, or TL082IDR. These parts maintain active product status with full manufacturer support and ongoing availability. TL082CMX/NOPB provides identical electrical specifications with Tape & Reel packaging. TL082ACDR and TL082CDR offer improved input bias current (30 pA vs. 50 pA) and reduced supply current (1.4 mA vs. 3.6 mA) with Cut Tape & Digi-Reel packaging. TL082BCDR provides the lowest input offset voltage (2 mV) among active alternatives.

For RoHS3 Compliance Requirement:

All substitute parts listed are ROHS3 compliant, whereas the main part TL082CMX is RoHS non-compliant. Any substitute selection automatically satisfies RoHS3 compliance requirements.

For Extended Temperature Range:

TL082IDR extends the operating temperature range to -40°C to 85°C, suitable for industrial and automotive applications requiring broader temperature coverage beyond the standard 0°C to 70°C range.

For Automotive Applications:

TL082ACD and TL082CD from STMicroelectronics carry AEC-Q100 automotive qualification. These parts are suitable for automotive-grade designs requiring formal qualification documentation.

For Packaging Format Flexibility:

TL082ACPSR and TL082CPSR provide 8-SO packaging (0.209" width) as an alternative to standard 8-SOIC (0.154" width), accommodating different PCB layout requirements while maintaining functional equivalence.

For Inventory Availability:

TL082BCD offers the highest inventory level (888,900 pcs) in Tube packaging format. TL082CDR provides 105,200 pcs in Cut Tape & Digi-Reel format. TL082IDR provides 65,100 pcs in Cut Tape & Digi-Reel format.

Frequently Asked Questions (FAQ)

Q1: Can TL082CMX be directly replaced with TL082CMX/NOPB?

A: Yes. TL082CMX/NOPB is a direct functional equivalent with identical electrical specifications (13V/µs slew rate, 4 MHz gain bandwidth product, 50 pA input bias current, 5 mV input offset voltage). The primary difference is packaging format: TL082CMX/NOPB is supplied in Tape & Reel format versus the original part's standard packaging. Both are 8-SOIC (0.154", 3.90mm width) surface mount packages with identical PCB footprints.

Q2: What are the key differences between TL082CMX and TL082ACDR?

A: TL082ACDR maintains J-FET dual-circuit topology and 8-SOIC package compatibility. Electrical differences include: reduced input bias current (30 pA vs. 50 pA), reduced input offset voltage (3 mV vs. 5 mV), reduced supply current (1.4 mA vs. 3.6 mA per channel), reduced output current per channel (10 mA vs. 17 mA), and reduced gain bandwidth product (3 MHz vs. 4 MHz). TL082ACDR is active product status with ROHS3 compliance. Supply voltage range is narrower (10V to 30V vs. 36V fixed).

Q3: Why would I select TL082IDR over other substitutes?

A: TL082IDR is selected when extended temperature range operation is required. It operates from -40°C to 85°C compared to the standard 0°C to 70°C range of other alternatives. Electrical specifications match TL082ACDR and TL082CDR. It is active product status with ROHS3 compliance and available in Cut Tape & Digi-Reel packaging with 65,100 pcs inventory.

Q4: Are TL082ACD and TL082CD suitable for automotive applications?

A: Yes. Both TL082ACD and TL082CD from STMicroelectronics carry AEC-Q100 automotive qualification. They are J-FET dual-circuit operational amplifiers in 8-SOIC packages. TL082CD is active product status with 21,083 pcs inventory in Tube packaging. TL082ACD is obsolete status. Both feature 16V/µs slew rate and 20 pA input bias current, meeting automotive-grade performance requirements.

Q5: What is the difference between 8-SOIC (0.154") and 8-SO (0.209") packages?

A: Both are 8-pin surface mount packages with identical pin configurations and electrical compatibility. The primary difference is package width: 8-SOIC measures 0.154" (3.90mm) width, while 8-SO measures 0.209" (5.30mm) width. PCB footprints differ accordingly. TL082ACPSR and TL082CPSR use the wider 8-SO format. Standard 8-SOIC format is more common in modern designs.

Q6: Can I use TL082BCD as a substitute if I need the highest inventory availability?

A: Yes. TL082BCD is a direct functional equivalent with 888,900 pcs inventory in Tube packaging. It features identical electrical specifications to TL082CMX (13V/µs slew rate, 4 MHz gain bandwidth product) with the exception of reduced input offset voltage (2 mV vs. 5 mV). It is obsolete product status but ROHS3 compliant. The 8-SOIC (0.154", 3.90mm) package is footprint-compatible with the original part.

Q7: What compliance certifications differ between the main part and substitutes?

A: The main part TL082CMX is RoHS non-compliant. All substitute parts are ROHS3 compliant. Additionally, TL082ACD and TL082CD carry AEC-Q100 automotive qualification, which is not present in other alternatives. All parts maintain REACH Unaffected status and EAR99 ECCN classification.

Q8: Which substitute offers the best balance of active status, compliance, and standard packaging?

A: TL082CDR provides optimal balance: active product status, ROHS3 compliance, standard 8-SOIC (0.154", 3.90mm) package, 105,200 pcs inventory, and Cut Tape & Digi-Reel packaging format. Electrical specifications include 13V/µs slew rate, 3 MHz gain bandwidth product, 30 pA input bias current, and 3 mV input offset voltage.
