TL061CD Equivalent & Substitute Parts
Part Overview
The TL061CD is a J-FET input operational amplifier manufactured by Texas Instruments in 8-SOIC surface mount packaging. This device is classified as a Last Time Buy product, indicating that Texas Instruments has discontinued active production. The TL061CD features a single amplifier circuit with J-FET input stage technology, delivering low input bias current and high input impedance characteristics suitable for precision signal conditioning applications.
Due to Last Time Buy status, equivalent substitute parts are necessary for ongoing design support and production continuity. Substitute options include direct pin-compatible alternatives from the same manufacturer in active production status, as well as functionally equivalent general-purpose amplifiers from alternative manufacturers.

Substitute Part Grouping Explanation
Substitution logic for the TL061CD is based on the following criteria:
Primary Substitutes (Direct J-FET Equivalents): Parts TL061CDR, TL061ACDT, TL061CDT, and TL061IDT maintain identical amplifier type (J-FET), matching slew rate (3.5 V/µs), gain bandwidth product (1 MHz), input bias current (30 pA), and input offset voltage (3 mV). These parts are pin-compatible and functionally equivalent, differing only in packaging format (Cut Tape & Digi-Reel versus Tube) and temperature rating. TL061CDR is the direct active production equivalent in Cut Tape packaging. TL061IDT and TL061CDT offer extended temperature range (-40°C to 105°C and 0°C to 70°C respectively) with identical electrical performance.
Secondary Substitutes (General-Purpose Alternatives): Parts UA741CD, UA741CDT, UA741ID, and UA741IDT are general-purpose amplifiers that share the same 8-SOIC package and 1 MHz gain bandwidth product. These devices differ in amplifier type (General Purpose versus J-FET), resulting in higher input bias current (10–80 nA versus 30 pA) and lower slew rate (0.5 V/µs versus 3.5 V/µs). These substitutes are suitable only for applications where J-FET input characteristics are not critical.
Alternative Manufacturer Substitute: The MC33171DR2G from onsemi is a general-purpose amplifier in 8-SOIC packaging with 1.8 MHz gain bandwidth product and extended supply voltage range (3–44 V). This part differs significantly in amplifier type, input bias current (20 nA), and slew rate (2.1 V/µs), making it suitable for applications with relaxed input impedance requirements.

Engineering Selection Recommendations
For Direct Replacement (Recommended): Select TL061CDR from Texas Instruments or TL061CDT from STMicroelectronics. Both parts maintain identical electrical specifications to the TL061CD, including J-FET amplifier type, 3.5 V/µs slew rate, and 30 pA input bias current. TL061CDR is available in higher quantity (55,400 units) and is the manufacturer-recommended direct substitute. Both parts are ROHS3 compliant and carry MSL Level 1 rating.
For Extended Temperature Applications: Select TL061IDT from STMicroelectronics, which provides identical electrical performance to the TL061CD with extended operating temperature range (-40°C to 105°C). This part is suitable for applications requiring operation beyond the standard 0°C to 70°C range while maintaining J-FET input characteristics.
For General-Purpose Applications (Non-Critical Input Impedance): The UA741CDT or UA741IDT from STMicroelectronics are suitable alternatives when J-FET input characteristics are not required. These parts offer Active product status and extended temperature range options. Note that these substitutes exhibit higher input bias current (10 nA) and lower slew rate (0.5 V/µs) compared to the TL061CD.
For Alternative Manufacturer Requirement: The MC33171DR2G from onsemi provides a general-purpose amplifier solution in 8-SOIC packaging with Active product status. This part is suitable only for applications where input impedance and slew rate specifications are not critical design parameters.
All recommended substitutes are ROHS3 compliant, carry MSL Level 1 rating, and are classified as EAR99 for export control purposes.
Frequently Asked Questions (FAQ)
Q: Can TL061CDR be used as a direct replacement for TL061CD?
A: Yes. TL061CDR is the manufacturer-recommended direct substitute. Both parts are J-FET amplifiers with identical electrical specifications: 3.5 V/µs slew rate, 1 MHz gain bandwidth product, 30 pA input bias current, and 3 mV input offset voltage. The primary difference is packaging format (Cut Tape & Digi-Reel versus Tube) and product status (Active versus Last Time Buy). Pin configuration and electrical performance are identical.
Q: What is the difference between TL061CDT and TL061IDT?
A: Both parts are J-FET amplifiers from STMicroelectronics with identical electrical specifications and 8-SOIC packaging. The primary difference is operating temperature range: TL061CDT operates from 0°C to 70°C, while TL061IDT operates from -40°C to 105°C. Select TL061IDT for applications requiring extended temperature operation.
Q: Can UA741 series parts replace TL061CD?
A: UA741 series parts are functionally compatible but not electrically equivalent. Both share the same 8-SOIC package and 1 MHz gain bandwidth product. However, UA741 devices are general-purpose amplifiers with significantly different input characteristics: 10–80 nA input bias current (versus 30 pA for TL061CD) and 0.5 V/µs slew rate (versus 3.5 V/µs). Use UA741 substitutes only in applications where high input impedance and fast slew rate are not required.
Q: Is MC33171DR2G compatible with TL061CD?
A: MC33171DR2G is pin-compatible in 8-SOIC packaging but differs significantly in electrical performance. This onsemi general-purpose amplifier has 1.8 MHz gain bandwidth product, 2.1 V/µs slew rate, and 20 nA input bias current. It is suitable only for applications where J-FET input characteristics and 3.5 V/µs slew rate are not critical specifications.
Q: What packaging options are available for TL061 substitutes?
A: TL061 substitutes are available in three packaging formats: Tube (TL061CD), Cut Tape & Digi-Reel (TL061CDR, TL061CDT, TL061IDT), and Tape & Reel (TL061ACDT). Select packaging based on production volume and assembly process requirements. Cut Tape & Digi-Reel format is standard for high-volume automated assembly.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All substitute parts listed—TL061CDR, TL061ACDT, TL061CDT, TL061IDT, UA741CD, UA741CDT, UA741ID, UA741IDT, and MC33171DR2G—are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.
Q: What is the supply voltage range for TL061 substitutes?
A: TL061CD and all TL061 substitutes (TL061CDR, TL061ACDT, TL061CDT, TL061IDT) operate with a supply voltage span of 6–36 V (minimum 6 V for STMicroelectronics variants, 7 V for Texas Instruments TL061CD). UA741 variants operate at 7–36 V (Texas Instruments) or 10–44 V (STMicroelectronics). MC33171DR2G operates at 3–44 V. Verify supply voltage compatibility with your application before substitution.
