TL061ACPSRE4 Equivalent & Substitute Parts

Part Overview

The TL061ACPSRE4 is a J-FET input operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design requirements and production continuity. The TL061ACPSRE4 features a single amplifier circuit with J-FET input characteristics, delivering a 1 MHz gain bandwidth product and 3.5 V/µs slew rate. Substitute parts must maintain functional compatibility across electrical specifications and physical packaging constraints.

Substitute Part Grouping Explanation

Substitution of the TL061ACPSRE4 is determined by the following critical parameters: single circuit configuration, 1 MHz gain bandwidth product, surface mount 8-SOIC package type, supply voltage range compatibility (minimum 7 V, maximum 36 V), and operating temperature range (0°C ~ 70°C). The substitute parts identified—UA741CD, UA741CDT, UA741ID, and UA741IDT—share the same gain bandwidth product (1 MHz), single circuit architecture, and surface mount 8-SOIC packaging. All substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

The primary distinction between the TL061ACPSRE4 and substitute parts lies in amplifier type classification: the main part is J-FET input, while substitutes are general purpose amplifiers. This functional difference does not preclude substitution where circuit topology permits general purpose amplifier operation. Supply voltage range compatibility is maintained across all parts within the specified 7 V to 36 V envelope, with certain substitutes offering extended ranges. Operating temperature ranges vary among substitutes, with UA741ID and UA741IDT supporting extended industrial temperature specifications (-40°C ~ 105°C).

Engineering Selection Recommendations

UA741CDT is the primary recommended substitute for the TL061ACPSRE4. This part maintains active product status with STMicroelectronics, ensuring long-term availability and supply chain stability. The UA741CDT is ROHS3 compliant and offers extended maximum supply voltage (44 V versus 36 V), providing additional design margin. With 82,190 units in current inventory, this part presents optimal procurement conditions.

UA741IDT serves as the secondary recommendation for applications requiring extended operating temperature range (-40°C ~ 105°C). This part is actively manufactured by STMicroelectronics and maintains identical electrical specifications to UA741CDT while supporting industrial temperature specifications. Inventory availability is 9,200 units.

UA741ID is suitable for applications requiring extended temperature operation with tube packaging. This part is actively produced by STMicroelectronics with 1,323 units available. Operating temperature range extends to -40°C ~ 105°C.

UA741CD is classified as Last Time Buy status, indicating limited future availability. This part is suitable only for immediate replacement requirements where extended temperature operation is not necessary. Current inventory is 38,276 units.

All substitute parts share the critical 1 MHz gain bandwidth product and single circuit configuration. Package width differences (0.209" for TL061ACPSRE4 versus 0.154" for all substitutes) require PCB layout verification. Supply voltage minimum specification increases from 7 V to 10 V for STMicroelectronics variants; circuit designs operating below 10 V must utilize UA741CD.

Frequently Asked Questions (FAQ)

Q: Can the UA741 series directly replace the TL061ACPSRE4 in all applications?

A: Direct substitution is possible where circuit topology does not depend on J-FET input characteristics specific to the TL061ACPSRE4. The UA741 series provides general purpose amplifier functionality with identical gain bandwidth product (1 MHz) and single circuit configuration. Applications requiring ultra-low input bias current (30 pA) may experience performance differences, as UA741 variants specify 10 nA to 80 nA input bias current.

Q: What is the significance of the package width difference between TL061ACPSRE4 and substitute parts?

A: The TL061ACPSRE4 uses an 8-SOIC package with 0.209" width, while all substitute parts use 0.154" width 8-SOIC packages. This dimensional difference requires PCB layout verification to confirm pin-to-pin compatibility and trace routing feasibility. Physical footprint differences may necessitate PCB redesign.

Q: Which substitute part should be selected for designs operating below 10 V supply voltage?

A: The UA741CD is the only substitute part with a 7 V minimum supply voltage specification, matching the TL061ACPSRE4. STMicroelectronics variants (UA741CDT, UA741ID, UA741IDT) specify 10 V minimum supply voltage and are unsuitable for designs operating below this threshold.

Q: What are the packaging format differences among substitute parts?

A: UA741CD and UA741ID are supplied in tube packaging. UA741CDT and UA741IDT are supplied in cut tape (CT) and Digi-Reel format. Packaging selection depends on production volume and assembly line requirements.

Q: How do slew rate differences affect circuit performance?

A: The TL061ACPSRE4 specifies 3.5 V/µs slew rate, while all UA741 substitutes specify 0.5 V/µs. This represents a 7-fold reduction in slew rate capability. Applications with high-frequency signal conditioning or fast transient response requirements may experience performance degradation. Circuit simulation and testing are necessary to confirm acceptable performance in rate-sensitive applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all identified substitute parts (UA741CD, UA741CDT, UA741ID, UA741IDT) are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), matching the TL061ACPSRE4 compliance profile.

Q: Which substitute part offers the longest product lifecycle?

A: UA741CDT and UA741IDT are actively manufactured by STMicroelectronics with active product status, ensuring continued availability. UA741CD is classified as Last Time Buy, indicating limited future production. UA741ID maintains active status with extended temperature specifications.
