Part Overview

The TL061ACD is a J-FET input operational amplifier manufactured by STMicroelectronics, housed in an 8-SOIC surface mount package. This device is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and production requirements. The TL061ACD serves applications requiring low input bias current and low input offset voltage characteristics typical of J-FET amplifier designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL061ACD is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier Type: J-FET
• Number of Circuits: 1
• Slew Rate: 3.5 V/µs
• Gain Bandwidth Product: 1 MHz
• Current - Input Bias: 30 pA
• Voltage - Input Offset: 3 mV
• Current - Supply: 200 µA
• Current - Output / Channel: 20 mA

Mechanical & Environmental Criteria:

• Package / Case: 8-SOIC surface mount configuration
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Supply Voltage Compatibility: The TL061ACD operates across 6 V to 36 V supply span. Substitute parts must support this range or a compatible subset. Parts with minimum supply voltage of 7 V remain functionally compatible in applications utilizing 7 V or higher supply voltages.

Temperature Range Considerations: The TL061ACD operates from 0°C to 70°C. Substitute parts with extended temperature ranges (-40°C to 105°C or -40°C to 85°C) provide broader operational capability and are classified as upgrades rather than direct equivalents.

Packaging Format: All listed substitutes maintain the 8-SOIC package footprint. The TL061CPSR variant uses an 8-SO package (0.209", 5.30mm Width) and requires PCB layout verification for mechanical compatibility despite electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Active Status): The TL061ACDR (Texas Instruments) and TL061CDR (Texas Instruments) are the primary recommended substitutes for the obsolete TL061ACD. Both parts maintain identical electrical specifications and 8-SOIC package configuration. TL061ACDR is supplied in Tape & Reel packaging, while TL061CDR is supplied in Cut Tape & Digi-Reel format. Both are ROHS3 compliant and carry Active product status, ensuring long-term availability and supply chain stability.

Upgrade Options (Extended Temperature Range): The TL061ID (STMicroelectronics) and TL061IDR (Texas Instruments) provide extended operating temperature ranges (-40°C to 105°C and -40°C to 85°C respectively) while maintaining all core electrical parameters. These upgrades are suitable for applications requiring broader thermal performance. TL061IDR carries Active status and represents the highest inventory availability (18,558 units).

Last Time Buy Alternatives: The TL061CD (Texas Instruments, Tube packaging) and TL061CPSR (Texas Instruments, Tape & Reel packaging) are classified as Last Time Buy. These parts remain electrically equivalent but have limited production windows. The TL061CPSR uses an 8-SO package (0.209", 5.30mm Width) requiring PCB layout verification for mechanical fit despite electrical compatibility.

Compliance & Regulatory: All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), REACH Unaffected status, and identical ECCN and HTSUS classifications as the original TL061ACD, ensuring regulatory continuity.

Frequently Asked Questions (FAQ)

Q: Can TL061ACDR directly replace TL061ACD without circuit modification?

A: Yes. TL061ACDR maintains identical electrical specifications (slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current) and the same 8-SOIC package footprint. The minimum supply voltage increases from 6 V to 7 V; applications operating at 7 V or higher supply voltage experience no functional difference.

Q: What is the difference between TL061CDR and TL061ACDR?

A: Both parts are electrically identical with matching specifications and 8-SOIC packaging. The primary difference is packaging format: TL061ACDR is supplied in Tape & Reel (TR), while TL061CDR is supplied in Cut Tape (CT) & Digi-Reel format. Selection depends on assembly process requirements and inventory management preferences.

Q: Why would I select TL061IDR over TL061CDR?

A: TL061IDR provides an extended operating temperature range (-40°C to 85°C) compared to TL061CDR (0°C to 70°C). Applications requiring operation below 0°C or above 70°C necessitate TL061IDR. Additionally, TL061IDR carries Active product status with significantly higher inventory availability (18,558 units versus 55,400 units for TL061CDR), though both are currently in production.

Q: Is TL061CPSR mechanically compatible with TL061ACD?

A: TL061CPSR is electrically equivalent but uses an 8-SO package (0.209", 5.30mm Width) versus the 8-SOIC package (0.154", 3.90mm Width) of TL061ACD. PCB layout verification is required to confirm mechanical fit. Pin spacing and lead geometry differ between these package types.

Q: What supply voltage range should I use for TL061ACDR?

A: TL061ACDR operates across 7 V to 36 V supply span. The original TL061ACD supports 6 V minimum; applications utilizing 6 V supply voltage require either the original TL061ACD or TL061ID (which maintains 6 V minimum). For 7 V and higher supplies, TL061ACDR is fully compatible.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (TL061ACDR, TL061ID, TL061IDR, TL061CD, TL061CDR, TL061CPSR) are ROHS3 compliant with MSL Level 1 (Unlimited) and REACH Unaffected status, matching the regulatory profile of the original TL061ACD.

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

A: TL061IDR (Texas Instruments) carries Active product status with the highest current inventory (18,558 units) and represents the most secure long-term supply option. TL061CDR also maintains Active status with substantial inventory (55,400 units). Both TL061CD and TL061CPSR are classified as Last Time Buy with limited production windows.

Q: Can I use TL061ID as a drop-in replacement?

A: TL061ID is electrically and mechanically compatible with TL061ACD. However, TL061ID is classified as Obsolete (same status as TL061ACD), making it unsuitable for long-term production requirements. TL061IDR (Active status) is the preferred upgrade path for extended temperature applications.
