Engineering Selection Recommendations

Direct Replacement (Highest Compatibility):

TLE2072CDR is the primary substitute for TLE2072CDRG4. Both parts are manufactured by Texas Instruments, share identical electrical specifications (45 V/µs slew rate, 10 MHz gain bandwidth product, 1 pA input bias current, 300 µV input offset voltage), and operate across the same supply voltage range (4.5 V to 38 V). The TLE2072CDR is currently in active production status with 2814 pieces in stock, providing immediate availability. Packaging differs only in format (Cut Tape & Digi-Reel® versus Digi-Reel®), with no impact on component functionality. Both are ROHS3 compliant and REACH unaffected.

J-FET Substitutes with Extended Temperature Range:

The LT1057 series (LT1057IS8#PBF, LT1057IS8#TRPBF, LT1057S8#PBF, LT1057S8#TRPBF) manufactured by Analog Devices Inc. are J-FET amplifiers in 8-SOIC packages with active product status. These parts maintain J-FET input architecture and operate within the TLE2072CDRG4 supply voltage range (20 V to 36 V minimum overlap). The LT1057 series exhibits lower slew rate (13 V/µs versus 45 V/µs) and lower gain bandwidth product (5 MHz versus 10 MHz), with superior input bias current performance (7 pA versus 1 pA). Operating temperature extends to -40°C to 85°C for IS8 variants, providing broader thermal coverage. These parts are suitable for applications where the reduced slew rate and bandwidth are acceptable.

J-FET Substitute with Extended Supply Voltage:

LT1169CS8#PBF is a J-FET amplifier from Analog Devices Inc. with the widest supply voltage range (9 V to 40 V), accommodating the TLE2072CDRG4 operating envelope. Input bias current is 4 pA with 600 µV input offset voltage. Slew rate (4.2 V/µs) and gain bandwidth product (5.3 MHz) are lower than the original part. This substitute is appropriate for applications requiring extended positive supply voltage capability.

General Purpose Alternatives:

AS358AMTR-G1 (Diodes Incorporated) and MC1458DT (STMicroelectronics) are general-purpose amplifiers in 8-SOIC packages with 2 circuits. These parts do not maintain J-FET input architecture but provide functional amplification in identical package configurations. AS358AMTR-G1 offers extended operating temperature (-40°C to 85°C) and lower supply current (700 µA). MC1458DT operates at 0°C to 70°C with 1 MHz gain bandwidth product and 0.8 V/µs slew rate, suitable only for low-frequency applications. These alternatives are applicable only when J-FET input characteristics are not required.

Audio Amplifier Alternatives:

LM833DR2G (onsemi) and LM833DT (STMicroelectronics) are audio-grade amplifiers with 15 MHz gain bandwidth product and 7 V/µs slew rate. LM833DT provides the widest operating temperature range (-40°C to 105°C) and operates across 5 V to 30 V supply range. These parts are suitable for audio and general-purpose signal conditioning applications where audio-grade performance is specified.

Frequently Asked Questions (FAQ)

Q: Can TLE2072CDR directly replace TLE2072CDRG4 without circuit modifications?

A: Yes. TLE2072CDR is electrically and mechanically identical to TLE2072CDRG4. Both parts share the same J-FET input architecture, slew rate (45 V/µs), gain bandwidth product (10 MHz), input bias current (1 pA), input offset voltage (300 µV), supply current (3.1 mA), output current (48 mA), and supply voltage range (4.5 V to 38 V). The 8-SOIC package pinout is identical. No circuit modifications are required. The only difference is packaging format and product status (TLE2072CDR is active production).

Q: What is the key difference between J-FET and General Purpose amplifier substitutes?

A: J-FET input amplifiers (TLE2072CDRG4, TLE2072CDR, LT1057 series, LT1169CS8#PBF) feature extremely low input bias current (1 pA to 7 pA range) and high input impedance, making them suitable for high-impedance signal sources and precision measurement applications. General Purpose amplifiers (AS358AMTR-G1, MC1458DT) have higher input bias current (20 nA to 30 nA) and lower input impedance, appropriate for standard signal conditioning and buffering applications. Selection depends on whether the application requires J-FET input characteristics.

Q: Why do LT1057 series parts have lower slew rate and bandwidth than TLE2072CDRG4?

A: The LT1057 series is designed for precision, low-noise applications with emphasis on input bias current performance (7 pA) and input offset voltage stability (220 µV). The lower slew rate (13 V/µs) and gain bandwidth product (5 MHz) reflect design trade-offs optimizing for precision over speed. Applications requiring 45 V/µs slew rate and 10 MHz bandwidth must use TLE2072CDR or higher-performance alternatives.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (TLE2072CDR, LT1057 series, LT1169CS8#PBF, AS358AMTR-G1, LM833 series, MC1458DT) are ROHS3 compliant and REACH unaffected, matching the regulatory compliance of TLE2072CDRG4.

Q: What is the supply voltage compatibility range for substitutes?

A: TLE2072CDRG4 operates from 4.5 V to 38 V. TLE2072CDR matches this range exactly. LT1057 series requires minimum 20 V supply (incompatible with 4.5 V to 20 V applications). LT1169CS8#PBF operates from 9 V to 40 V (incompatible with 4.5 V to 9 V applications). AS358AMTR-G1 operates from 3 V to 36 V (compatible). LM833 series operates from 5 V to 30 V or 10 V to 36 V depending on variant (partially compatible). MC1458DT operates from 5 V to 30 V (partially compatible). Verify supply voltage requirements before substitution.

Q: Which substitute offers the best inventory availability?

A: LM833DT (STMicroelectronics) has the highest inventory with 166,607 pieces in stock. LM833DR2G (onsemi) has 45,855 pieces. AS358AMTR-G1 (Diodes Incorporated) has 24,300 pieces. TLE2072CDR has 2,814 pieces. LT1057 series variants range from 1,515 to 2,900 pieces. Inventory levels should be verified at time of procurement.

Q: Can MC1458DT substitute for TLE2072CDRG4 in high-frequency applications?

A: No. MC1458DT has 1 MHz gain bandwidth product and 0.8 V/µs slew rate, insufficient for applications requiring 10 MHz bandwidth and 45 V/µs slew rate. MC1458DT is suitable only for low-frequency applications below 1 MHz.

Q: What is the operating temperature range difference between substitutes?

A: TLE2072CDRG4 operates 0°C to 70°C. TLE2072CDR matches this range. LT1057IS8 variants extend to -40°C to 85°C. LT1057S8 variants remain 0°C to 70°C. LT1169CS8#PBF operates 0°C to 70°C. AS358AMTR-G1 extends to -40°C to 85°C. LM833DR2G extends to -40°C to 85°C. LM833DT extends to -40°C to 105°C. MC1458DT operates 0°C to 70°C. Select based on application temperature requirements.
