Engineering Selection Recommendations

Primary Recommendation - Direct Substitution:

The TLE2082ACDR (Tape & Reel packaging) is the recommended primary substitute for the TLE2082ACDG4. This part maintains identical electrical specifications across all key parameters: 40V/µs slew rate, 10 MHz gain bandwidth product, 20 pA input bias current, and 700 µV input offset voltage. The TLE2082ACDR is in Active product status with 2130 pieces in inventory, providing superior long-term supply availability compared to the Last Time Buy TLE2082ACDG4. Both parts are ROHS3 compliant and MSL Level 1. The only difference is packaging format (Tape & Reel versus Tube), which does not affect electrical performance or circuit compatibility.

Secondary Recommendation - Electrical Equivalent:

The TLE2082ACD (Tube packaging) provides identical electrical specifications to the TLE2082ACDG4 with significantly higher inventory availability (100,288 pieces). This part is also Last Time Buy status but offers extended supply window due to stock levels. Use this part when Tube packaging format is preferred or when Tape & Reel supply becomes constrained.

Alternative Consideration - Performance Trade-offs:

The AD8620ARZ series (AD8620ARZ, AD8620ARZ-REEL, AD8620ARZ-REEL7) offers superior electrical performance with 60V/µs slew rate, 25 MHz gain bandwidth product, and exceptionally low 3 pA input bias current. However, these parts have restricted supply voltage range (10V to 26V maximum versus 4.5V to 38V) and extended operating temperature range (-40°C to 125°C). Selection of AD8620ARZ variants requires verification that circuit supply voltages remain within the 10V to 26V window. All AD8620ARZ variants are in Active status with substantial inventory availability.

Not Recommended - Incompatible Parameters:

The TL082CMX/NOPB is not recommended as a direct substitute. Although it maintains J-FET dual-channel 8-SOIC configuration, it exhibits significantly degraded electrical performance: 13V/µs slew rate (versus 40V/µs), 4 MHz gain bandwidth product (versus 10 MHz), 50 pA input bias current (versus 20 pA), and 5000 µV input offset voltage (versus 700 µV). Additionally, the supply voltage range is fixed at 36V (±18V) rather than the flexible 4.5V to 38V range. This part is suitable only for applications with relaxed performance requirements.

Frequently Asked Questions (FAQ)

Q1: Can I directly replace TLE2082ACDG4 with TLE2082ACDR without circuit modification?

A: Yes. The TLE2082ACDR is electrically identical to the TLE2082ACDG4 across all specified parameters. The only difference is packaging format (Tape & Reel versus Tube). No circuit modifications are required. Both parts are pin-compatible in 8-SOIC surface mount footprints and maintain identical electrical performance.

Q2: What is the difference between TLE2082ACDG4 and TLE2082ACD?

A: Both parts are electrically identical with matching specifications for slew rate, gain bandwidth product, input bias current, and input offset voltage. The primary difference is inventory availability: TLE2082ACD has 100,288 pieces in stock versus 910 pieces for TLE2082ACDG4. Both are Last Time Buy status. The TLE2082ACD provides extended supply assurance due to higher stock levels.

Q3: Why is the AD8620ARZ not a direct substitute despite being a J-FET dual-channel amplifier?

A: The AD8620ARZ has different electrical performance characteristics and supply voltage constraints. While it offers superior slew rate (60V/µs versus 40V/µs) and gain bandwidth product (25 MHz versus 10 MHz), the maximum supply voltage is limited to 26V compared to 38V for the TLE2082ACDG4. Applications requiring supply voltages above 26V cannot use AD8620ARZ variants. Circuit evaluation is required to confirm compatibility.

Q4: Can I use AD712JRZ as a substitute for TLE2082ACDG4?

A: The AD712JRZ is not recommended as a direct substitute. Although it maintains J-FET dual-channel 8-SOIC configuration, it exhibits significantly lower slew rate (20V/µs versus 40V/µs) and gain bandwidth product (4 MHz versus 10 MHz). The input offset voltage is superior (300 µV versus 700 µV), but the overall performance profile is degraded. Use AD712JRZ only in applications with relaxed bandwidth and slew rate requirements.

Q5: What does "Last Time Buy" status mean for the TLE2082ACDG4?

A: Last Time Buy indicates that Texas Instruments has discontinued production of this part. Current inventory will be depleted without replenishment. Customers must transition to alternative parts before stock exhaustion. The TLE2082ACDR (Active status) is the recommended transition path, offering identical specifications with continued manufacturing support.

Q6: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed in this document maintain ROHS3 compliance and MSL Level 1 (Unlimited moisture sensitivity). All parts are suitable for lead-free soldering processes and meet environmental compliance requirements.

Q7: What packaging options are available for electrically equivalent substitutes?

A: The TLE2082ACDR is available in Tape & Reel (TR) packaging. The TLE2082ACD is available in Tube packaging. Both maintain identical electrical specifications. For Analog Devices alternatives, the AD8620ARZ series offers multiple packaging options: Tube (AD8620ARZ), Tape & Reel (AD8620ARZ-REEL), and Cut Tape & Digi-Reel® (AD8620ARZ-REEL7).

Q8: Can I mix packaging formats in production?

A: Yes. All variants of the same base part number (TLE2082 or AD8620) are electrically identical and can be used interchangeably in circuit designs. Packaging format selection is determined by manufacturing process requirements (automated tape handling versus manual tube handling) and does not affect electrical performance or circuit compatibility.
