Engineering Selection Recommendations

Tier 1 - Direct Functional Equivalent (Recommended Primary Substitute):

TLE2082ACDR is the active equivalent of TLE2082ACDRG4. Both parts share identical electrical specifications, J-FET architecture, dual-circuit configuration, and 8-SOIC packaging. The only difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. Tube). This part maintains full parameter compatibility and is the preferred substitute for direct replacement in existing designs.

Tier 2 - Performance-Enhanced Substitutes (Extended Operating Range):

AD8620ARZ, AD8620ARZ-REEL, AD8620ARZ-REEL7, and AD8620BRZ offer superior performance characteristics including higher slew rate (60 V/µs), higher gain bandwidth product (25 MHz), and extended operating temperature range (-40°C to 125°C). These parts exceed the original specifications while maintaining 8-SOIC packaging and J-FET input architecture. Supply voltage range is narrower (10 V to 26 V) compared to the original (4.5 V to 38 V). These substitutes are suitable for applications requiring enhanced performance and wider temperature operation.

Tier 3 - Functional Substitutes (Performance Trade-offs):

AD712JRZ, AD712JRZ-REEL, and AD712JRZ-REEL7 provide J-FET dual-circuit operation in 8-SOIC packaging with active product status. These parts exhibit lower slew rate (20 V/µs) and lower gain bandwidth product (4 MHz) compared to the original specification. Input offset voltage is superior (300 µV vs. 700 µV). Supply voltage range is 9 V to 36 V. These substitutes are applicable in applications where the original slew rate and bandwidth are not critical performance requirements.

TL082CMX/NOPB is a J-FET dual-circuit operational amplifier in 8-SOIC packaging with active status. This part exhibits significantly reduced slew rate (13 V/µs), lower gain bandwidth product (4 MHz), and higher input offset voltage (5 mV). Supply voltage is fixed at 36 V. This substitute is suitable only for low-frequency signal conditioning applications where performance degradation is acceptable.

AD746JRZ provides enhanced slew rate (75 V/µs) and gain bandwidth product (13 MHz) in J-FET dual-circuit 8-SOIC configuration. However, input bias current is elevated (110 pA vs. 20 pA). This substitute is applicable in high-speed applications where input bias current elevation is tolerable.

All recommended substitutes maintain RoHS3 compliance and MSL 1 moisture sensitivity rating consistent with the original part.

Frequently Asked Questions (FAQ)

Q1: Can TLE2082ACDR directly replace TLE2082ACDRG4 in existing PCB assemblies?

A: Yes. TLE2082ACDR is the active equivalent with identical electrical specifications and 8-SOIC packaging. The only difference is packaging format (Tape & Reel vs. Tube). Both parts are pin-compatible and functionally equivalent. Verify with your assembly supplier that Tape & Reel format is compatible with your pick-and-place equipment.

Q2: What is the primary reason for substituting TLE2082ACDRG4?

A: TLE2082ACDRG4 is classified as obsolete. TLE2082ACDR is the active equivalent manufactured by Texas Instruments with identical performance characteristics. Substitution ensures long-term procurement availability and supply chain continuity.

Q3: Are AD8620 series parts suitable replacements for the TLE2082ACDRG4?

A: AD8620ARZ, AD8620ARZ-REEL, AD8620ARZ-REEL7, and AD8620BRZ are performance-enhanced substitutes. They exceed the original specifications in slew rate (60 V/µs vs. 40 V/µs), gain bandwidth product (25 MHz vs. 10 MHz), and input bias current (3 pA vs. 20 pA). However, the supply voltage range is narrower (10 V to 26 V vs. 4.5 V to 38 V). These parts are suitable if your application operates within the narrower supply voltage range and benefits from enhanced performance.

Q4: What are the trade-offs when using AD712JRZ as a substitute?

A: AD712JRZ provides active product status and J-FET dual-circuit operation in 8-SOIC packaging. Trade-offs include lower slew rate (20 V/µs vs. 40 V/µs) and lower gain bandwidth product (4 MHz vs. 10 MHz). Input offset voltage is superior (300 µV vs. 700 µV). This substitute is suitable for low-to-moderate frequency applications where the reduced slew rate and bandwidth are acceptable.

Q5: Is TL082CMX/NOPB a viable substitute?

A: TL082CMX/NOPB maintains J-FET dual-circuit 8-SOIC packaging and active product status. However, it exhibits significant performance degradation: slew rate of 13 V/µs (vs. 40 V/µs), gain bandwidth product of 4 MHz (vs. 10 MHz), and input offset voltage of 5 mV (vs. 700 µV). Additionally, supply voltage is fixed at 36 V. This substitute is only viable for low-frequency signal conditioning applications where performance reduction is acceptable.

Q6: What packaging format differences exist among the substitute parts?

A: All substitute parts use 8-SOIC (0.154", 3.90mm Width) surface mount packaging, maintaining mechanical compatibility. Packaging format variations (Tube, Tape & Reel, Cut Tape & Digi-Reel) affect procurement and assembly handling but do not impact electrical performance or PCB layout. Verify packaging format compatibility with your assembly process.

Q7: Do all substitute parts maintain RoHS3 and MSL 1 compliance?

A: Yes. All recommended substitute parts maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, consistent with the original TLE2082ACDRG4 specification.

Q8: Which substitute offers the best overall performance improvement?

A: AD8620BRZ provides the highest performance enhancement with 60 V/µs slew rate, 25 MHz gain bandwidth product, and the lowest input offset voltage (45 µV). It also extends operating temperature range to -40°C to 125°C. The trade-off is a narrower supply voltage range (10 V to 26 V). This substitute is optimal for applications requiring enhanced speed and precision within the specified supply voltage envelope.

Q9: Can I use AD746JRZ if my application requires high slew rate?

A: AD746JRZ provides 75 V/µs slew rate and 13 MHz gain bandwidth product, exceeding the original specification. However, input bias current is elevated to 110 pA (vs. 20 pA). This substitute is suitable for high-speed applications where elevated input bias current does not compromise circuit performance. Verify bias current effects on your specific application.

Q10: What is the inventory status of substitute parts?

A: TLE2082ACDR (2,130 pcs), TL082CMX/NOPB (2,264 pcs), AD712JRZ (7,752 pcs), AD712JRZ-REEL (16,400 pcs), AD712JRZ-REEL7 (38,531 pcs), AD746JRZ (2,113 pcs), AD8620ARZ (2,100 pcs), AD8620ARZ-REEL (2,610 pcs), AD8620ARZ-REEL7 (4,300 pcs), and AD8620BRZ (2,256 pcs) are all in stock.
