TL061CD Equivalent & Substitute Parts

Part Overview

The TL061CD is a J-FET input operational amplifier manufactured by STMicroelectronics in an 8-SOIC surface mount package. This device is classified as obsolete, indicating discontinued production and limited availability through standard distribution channels. The TL061CD serves applications requiring low input bias current and high input impedance characteristics typical of J-FET amplifier designs. Due to its obsolete status, identification of equivalent and substitute parts is necessary for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL061CD is determined by electrical and mechanical parameter compatibility within the J-FET operational amplifier category. The critical parameters governing substitution are:

Electrical Parameters:

• Amplifier Type: J-FET (required match)
• Number of Circuits: 1 (required match)
• Slew Rate: 3.5 V/µs (required match)
• Gain Bandwidth Product: 1 MHz (required match)
• Current - Input Bias: 30 pA (required match)
• Voltage - Input Offset: 3 mV (required match)
• Current - Supply: 200 µA (required match)
• Voltage - Supply Span: 6 V minimum to 36 V maximum (required match or compatible range)

Mechanical Parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width) (required match)
• Mounting Type: Surface Mount (required match)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (required match)
• Moisture Sensitivity Level: 1 (Unlimited) (required match)

Substitute parts are grouped into two categories: Direct Manufacturer Equivalents (same part number from different manufacturers) and Similar Manufacturer Parts (same base product number with different temperature or packaging variants). All substitute parts maintain identical electrical performance specifications and package dimensions, ensuring functional and mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TL061CDR (Texas Instruments)

The TL061CDR is the recommended substitute for the obsolete STMicroelectronics TL061CD. This part maintains identical electrical specifications and package configuration while offering active product status from Texas Instruments. The TL061CDR is available in Cut Tape and Digi-Reel packaging with 55,400 units in stock, ensuring procurement availability. Both parts operate within the 0°C to 70°C temperature range and meet ROHS3 compliance requirements.

Secondary Substitute: TL061ACDR (Texas Instruments)

The TL061ACDR provides an alternative with active product status and identical electrical performance. This variant is supplied in Tape & Reel packaging with 5,300 units available. Selection between TL061CDR and TL061ACDR depends on packaging requirements for automated assembly processes.

Extended Temperature Alternative: TL061IDR (Texas Instruments)

The TL061IDR extends the operating temperature range to -40°C to 85°C, suitable for applications requiring industrial or extended temperature performance. This part maintains all core electrical specifications and active product status. The TL061IDR is available in Cut Tape and Digi-Reel packaging with 18,558 units in stock.

Compatibility Note: Texas Instruments TL061CD

The Texas Instruments TL061CD (Last Time Buy status) provides direct part number equivalence but with a minimum supply voltage of 7 V compared to the STMicroelectronics 6 V minimum. This specification difference requires verification for applications operating at the lower voltage boundary.

Frequently Asked Questions (FAQ)

Q: Can TL061CDR directly replace TL061CD in existing designs?

A: Yes. The TL061CDR maintains identical electrical specifications (slew rate, gain bandwidth product, input bias current, input offset voltage, and supply current) and package configuration (8-SOIC surface mount). The primary difference is product status (active versus obsolete) and packaging format (Cut Tape & Digi-Reel versus tube). Designs operating at supply voltages of 7 V or higher are fully compatible. Designs requiring 6 V minimum supply operation should verify the Texas Instruments specification of 7 V minimum supply voltage.

Q: What is the difference between TL061ACDR and TL061CDR?

A: Both parts are manufactured by Texas Instruments with identical electrical performance and 8-SOIC package configuration. The primary difference is packaging format: TL061ACDR is supplied in Tape & Reel (TR) format for automated assembly, while TL061CDR is supplied in Cut Tape (CT) and Digi-Reel format. Selection depends on assembly process requirements and tape specifications.

Q: Is TL061IDR suitable as a substitute for TL061CD?

A: The TL061IDR is electrically compatible with identical core specifications. However, the operating temperature range differs: TL061IDR operates from -40°C to 85°C, while TL061CD operates from 0°C to 70°C. Selection of TL061IDR is appropriate for applications requiring extended temperature performance or industrial-grade specifications. For standard 0°C to 70°C applications, TL061CDR or TL061ACDR are preferred due to matching temperature specifications.

Q: Why is the STMicroelectronics TL061ACD listed as a substitute?

A: The TL061ACD is a variant of the same base product (TL061) from STMicroelectronics with identical electrical specifications and package configuration. However, both the TL061CD and TL061ACD are classified as obsolete. The TL061ACD is included for reference in legacy designs but does not resolve the obsolescence issue. Texas Instruments active alternatives (TL061CDR, TL061ACDR, TL061IDR) are recommended for new procurement.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), matching the original TL061CD specifications. This ensures environmental and regulatory compatibility across all substitutes.

Q: What packaging options are available for active substitutes?

A: Active Texas Instruments substitutes are available in two packaging formats: Tape & Reel (TL061ACDR) and Cut Tape & Digi-Reel (TL061CDR and TL061IDR). Selection depends on assembly equipment compatibility and procurement volume requirements. Tape & Reel format is standard for high-volume automated assembly, while Cut Tape format accommodates lower-volume or mixed-component assembly processes.

Q: Can the TL061CD be used interchangeably with UA741 series parts?

A: No. While some cross-reference lists reference UA741 variants, the UA741 is a bipolar input operational amplifier with fundamentally different electrical characteristics (higher input bias current, different slew rate, and different gain bandwidth product). The TL061CD is a J-FET input amplifier and is not electrically interchangeable with UA741 series parts. Substitution requires matching amplifier type (J-FET) and all specified electrical parameters.
