TL061ACPSR Equivalent & Substitute Parts

Part Overview

The TL061ACPSR 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, making identification of suitable substitute components essential for ongoing design support and production continuity. The TL061ACPSR delivers single-circuit amplification with low input bias current (30 pA) and operates across a 7V to 36V supply range, making it suitable for precision signal conditioning applications requiring low input offset voltage (3 mV) and moderate slew rate performance (3.5V/µs).

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL061ACPSR is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Single-circuit operational amplifier configuration (1 circuit required)
• Supply voltage range: minimum 7V, maximum 36V
• Surface mount packaging in 8-SOIC form factor
• Gain bandwidth product of 1 MHz or greater
• Input bias current performance suitable for precision applications
• Slew rate adequate for signal conditioning (≥0.5V/µs minimum)

Mechanical Compatibility:

• 8-SOIC package format (physical footprint compatibility)
• Surface mount technology

Compliance Requirements:

• ROHS3 compliance maintained
• Moisture sensitivity level 1 (unlimited)

The substitute parts identified below meet these criteria while accommodating variations in amplifier type (general purpose versus J-FET), operating temperature ranges, and product status. Selection depends on application-specific requirements for temperature range, supply current efficiency, and component availability.

Engineering Selection Recommendations

MC33171DR2G (onsemi) — Active Status, Extended Supply Range

• Suitable for applications requiring extended maximum supply voltage (44V vs. 36V)
• Active product status ensures long-term availability and manufacturing support
• Lowest input bias current among substitutes (20 nA) provides precision performance
• Higher gain bandwidth product (1.8 MHz) supports faster signal processing
• Wider operating temperature range (-40°C to 85°C) accommodates industrial environments
• Supply current comparable to TL061ACPSR (220 µA vs. 200 µA)
• Package width difference (3.90mm vs. 5.30mm) requires PCB layout verification

UA741CDT (STMicroelectronics) — Active Status, Matched Supply Range

• Active product status with established supply chain
• Supply voltage range (10V to 44V) overlaps TL061ACPSR minimum requirement (7V minimum)
• Lowest input offset voltage (1 mV) among all substitutes
• Identical gain bandwidth product (1 MHz) and operating temperature range (0°C to 70°C)
• Reduced input bias current (10 nA) improves precision over TL061ACPSR
• Higher supply current (1.7 mA) requires power budget evaluation
• Smaller package footprint (3.90mm) necessitates PCB redesign

UA741ID (STMicroelectronics) — Active Status, Extended Temperature Range

• Active product status with continuous manufacturing
• Extended operating temperature range (-40°C to 105°C) for extreme environment applications

• Identical supply voltage range and operating temperature to TL061ACPSR
• Higher input bias current (80 nA) compared to other substitutes
• Suitable only for applications where Texas Instruments sourcing is mandatory and immediate procurement is feasible

Frequently Asked Questions (FAQ)

Q: Can the MC33171DR2G directly replace the TL061ACPSR without PCB modifications?

A: Physical PCB modifications are required. The MC33171DR2G uses an 8-SOIC package with 3.90mm width, while the TL061ACPSR uses 5.30mm width. Footprint adjustment on the PCB is necessary. Electrical compatibility is maintained within the specified supply voltage range (7V to 36V).

Q: What is the primary difference between the TL061ACPSR and UA741 series substitutes?

A: The TL061ACPSR is a J-FET input amplifier with extremely low input bias current (30 pA), while UA741 series devices are general-purpose amplifiers with higher input bias current (10-80 nA). For applications sensitive to input bias current, the MC33171DR2G (20 nA) provides the closest performance match among active substitutes.

Q: Which substitute offers the best long-term availability?

A: UA741IDT (STMicroelectronics) is recommended for long-term availability, with active product status and highest inventory (9,200 pcs). MC33171DR2G (onsemi) also offers active status with significantly higher inventory (31,500 pcs), making it suitable for high-volume applications.

Q: Is the UA741CD suitable for new designs?

A: UA741CD carries last time buy status, indicating limited future manufacturing. It is not recommended for new designs. Use UA741CDT or UA741IDT instead, which maintain active status with STMicroelectronics.

Q: What are the supply current implications of substitution?

A: The TL061ACPSR draws 200 µA, while MC33171DR2G draws 220 µA (comparable). UA741 series devices draw 1.7 mA, representing an 8.5× increase. Power budget evaluation is required for battery-powered or low-power applications.

Q: Can substitutes operate at the TL061ACPSR minimum supply voltage of 7V?

A: MC33171DR2G operates from 3V minimum, providing full compatibility. UA741 series devices require minimum 10V (UA741CDT, UA741ID, UA741IDT) or 7V (UA741CD), with UA741CD matching the original specification exactly.

Q: What packaging formats are available for the substitute parts?

A: MC33171DR2G is supplied in cut tape and digi-reel format. UA741CD is supplied in tube format. UA741CDT and UA741IDT are supplied in cut tape and digi-reel format. UA741ID is supplied in tube format. Packaging selection depends on production handling requirements.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All identified substitute parts (MC33171DR2G, UA741CD, UA741CDT, UA741ID, UA741IDT) maintain ROHS3 compliance and moisture sensitivity level 1 (unlimited), matching the TL061ACPSR environmental specifications.
