Substitute Part Grouping Explanation
Substitution of the TL062ACDRE4 is determined by the following critical parameters: amplifier type (J-FET), number of circuits (2), package type (8-SOIC), and electrical specifications including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and supply voltage range.
Direct Equivalents maintain identical electrical specifications and J-FET architecture, differing only in packaging format or product status. These parts are pin-compatible and functionally interchangeable without circuit modification.
Upgraded Alternatives provide enhanced performance characteristics such as extended operating temperature range, improved input bias current specifications, or expanded supply voltage range, while maintaining the same package and core J-FET amplifier topology.
Functional Alternatives offer general-purpose amplifier solutions with different amplifier types (such as general-purpose rather than J-FET) but maintain compatibility through identical package geometry, pin count, and similar electrical performance within acceptable application parameters.

Engineering Selection Recommendations
Direct Equivalent Selection:
The TL062ACDR represents the primary direct equivalent to the TL062ACDRE4. Both devices are manufactured by Texas Instruments, maintain identical electrical specifications, and are housed in the 8-SOIC package. The TL062ACDR is currently in active production status with higher inventory availability (1741 units), making it the preferred choice for direct replacement in existing designs. Both parts are ROHS3 compliant with MSL 1 rating.
Enhanced Performance Alternatives:
The TL062ID and TL062IDT (STMicroelectronics) provide extended operating temperature range (-40°C to 105°C versus 0°C to 70°C) and expanded supply voltage range (6V to 36V versus 10V to 30V) while maintaining identical J-FET amplifier specifications. These parts are suitable for applications requiring broader environmental operating conditions. Both are ROHS3 compliant with MSL 1 rating and available in active production status.
The ADA4062-2ARZ, ADA4062-2ARZ-R7, and ADA4062-2BRZ (Analog Devices Inc.) offer superior performance characteristics including lower input bias current (2 pA), higher gain bandwidth product (1.4 MHz), and extended operating temperature range (-40°C to 125°C). The ADA4062-2BRZ variant provides the lowest input offset voltage (500 µV). These devices are ROHS3 compliant with MSL 1 rating and suitable for precision applications requiring enhanced specifications.
Functional Alternatives:
The AS358MTR-E1 (Diodes Incorporated) and LM258AWDT (STMicroelectronics) are general-purpose amplifiers offering pin-compatible 8-SOIC packages. These alternatives are appropriate only when J-FET input characteristics are not critical to application performance. The LM258AWDT includes automotive qualification (AEC-Q100) and extended temperature range (-40°C to 105°C). Both are ROHS3 compliant.
Frequently Asked Questions (FAQ)
Q: Can the TL062ACDRE4 be directly replaced with the TL062ACDR?
A: Yes. The TL062ACDR is a direct equivalent with identical electrical specifications, J-FET amplifier type, dual-circuit configuration, and 8-SOIC package. The primary difference is packaging format (Tape & Reel versus individual packaging) and active production status. Pin configuration and electrical performance are identical.
Q: What is the difference between TL062ACDT and TL062ID?
A: Both are STMicroelectronics J-FET amplifiers in 8-SOIC packages with identical core specifications. The TL062ACDT is supplied in Cut Tape & Digi-Reel format, while TL062ID is supplied in Tube packaging. The TL062ID offers extended operating temperature range (-40°C to 105°C). Both support expanded supply voltage range (6V to 36V) compared to the original TL062ACDRE4 (10V to 30V).
Q: Are the Analog Devices ADA4062 series parts suitable replacements?
A: The ADA4062-2ARZ, ADA4062-2ARZ-R7, and ADA4062-2BRZ are pin-compatible J-FET amplifiers in 8-SOIC packages offering enhanced performance. They provide lower input bias current (2 pA versus 30 pA), higher gain bandwidth product (1.4 MHz versus 1 MHz), and extended temperature range (-40°C to 125°C). These are suitable for applications where improved specifications are beneficial or required.
Q: When should general-purpose amplifiers like the LM258AWDT be considered?
A: General-purpose amplifiers should be considered only when the specific J-FET input characteristics of the TL062ACDRE4 are not essential to application performance. The LM258AWDT offers lower supply current (700 µA versus 200 µA) and broader supply voltage range (3V to 30V), but lacks the high input impedance and low input bias current characteristics of J-FET designs. The LM258AWDT includes automotive qualification (AEC-Q100).
Q: What packaging options are available for TL062 equivalents?
A: TL062 equivalents are available in multiple packaging formats: Tape & Reel (TL062ACDR), Cut Tape & Digi-Reel (TL062ACDT, TL062IDT), and Tube (TL062ID). All maintain the same 8-SOIC (0.154", 3.90mm Width) package geometry and pin configuration. Selection depends on production volume requirements and assembly process compatibility.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All substitute parts listed are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the original TL062ACDRE4. All parts are REACH unaffected and classified as EAR99 for export control purposes.
Q: What is the primary limitation of the TL062ACDT regarding input bias current?
A: The TL062ACDT specifies input bias current as 30 nA (nanoseconds) rather than 30 pA (picoseconds) as in the original TL062ACDRE4. This represents a 1000-fold increase in input bias current. Applications sensitive to input bias current specifications should verify compatibility or select alternatives such as TL062ID or ADA4062 series, which maintain the 30 pA specification.
Q: Can the TL062ACDRE4 be used in automotive applications?
A: The TL062ACDRE4 itself does not carry automotive qualification. However, automotive-qualified alternatives are available: the LM158DT and LM258AWDT both include AEC-Q100 qualification. If automotive qualification is required, these alternatives should be evaluated for functional compatibility with the original design.
