TLE2061ACD Equivalent & Substitute Parts

Part Overview

The TLE2061ACD is a J-FET input operational amplifier manufactured by Texas Instruments, designed for linear amplification applications. This device features a single amplifier circuit in an 8-SOIC surface mount package and is part of the Excalibur™ series. The TLE2061ACD is currently designated as Last Time Buy, indicating that the original manufacturer has ceased production or will cease production in the near future. Identifying equivalent and substitute parts is necessary to ensure continued availability for new designs, production continuity, and long-term system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE2061ACD is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Amplifier topology (J-FET input architecture)
• Number of circuits (single amplifier configuration)
• Slew rate (3.4 V/µs)
• Gain bandwidth product (2 MHz)
• Input bias current (4 pA)
• Supply current (290 µA)
• Output current capability (80 mA per channel)
• Supply voltage range (7 V to 36 V)
• Operating temperature range (0°C to 70°C)

Physical and Manufacturing Specifications:

• Package type (8-SOIC surface mount)
• Package dimensions (0.154" width, 3.90mm)
• RoHS3 compliance
• Moisture sensitivity level (MSL 1)

Packaging Format: The primary distinction between the TLE2061ACD and its substitute relates to packaging format (Tube versus Tape & Reel), which does not affect electrical performance or functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The TLE2061CDR serves as the direct substitute for the TLE2061ACD. Both devices are manufactured by Texas Instruments and share identical electrical specifications across all critical parameters including slew rate, gain bandwidth product, input bias current, supply current, output current capability, and supply voltage range.

The TLE2061CDR is designated as Active product status, ensuring continued availability and manufacturing support. This contrasts with the TLE2061ACD, which is Last Time Buy and will no longer be produced.

Both parts maintain full compliance with ROHS3 regulations and REACH requirements. Moisture sensitivity level is identical at MSL 1 (Unlimited), indicating no special handling requirements during storage or assembly.

The sole difference between these parts is packaging format: the TLE2061ACD is supplied in Tube packaging, while the TLE2061CDR is supplied in Tape & Reel format. This distinction affects only procurement, handling, and automated assembly processes and does not impact electrical performance or functional circuit behavior.

For new designs and production continuity, the TLE2061CDR is the appropriate selection. For existing applications currently using TLE2061ACD, direct substitution with TLE2061CDR is electrically and mechanically compatible.

Frequently Asked Questions (FAQ)

Q: Can the TLE2061CDR be used as a direct replacement for the TLE2061ACD in existing circuit designs?

A: Yes. The TLE2061CDR is electrically and mechanically equivalent to the TLE2061ACD. All critical electrical parameters, including slew rate, gain bandwidth product, input bias current, supply current, output current, and supply voltage range, are identical. Both devices use the same 8-SOIC surface mount package with identical pin configuration and dimensions.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube and Tape & Reel are packaging and delivery formats that do not affect the electrical characteristics of the component. Tube packaging is used for manual handling and smaller quantity orders, while Tape & Reel packaging is optimized for automated pick-and-place assembly equipment and higher volume production. The actual integrated circuit is identical in both formats.

Q: Why is the TLE2061ACD designated as Last Time Buy?

A: Last Time Buy designation indicates that the manufacturer has ceased or will cease production of this part number. This is a standard industry practice to notify customers of production discontinuation. The TLE2061CDR, with Active product status, represents the current production equivalent and should be used for new designs and ongoing production requirements.

Q: Are there any differences in the input offset voltage between these parts?

A: The TLE2061ACD specifies a maximum input offset voltage of 500 µV, while the TLE2061CDR specifies 600 µV. Both values fall within acceptable operational ranges for J-FET amplifier applications. Applications requiring the tighter 500 µV specification should evaluate the 600 µV specification of the TLE2061CDR against circuit requirements.

Q: Do both parts require special handling during storage or assembly?

A: No. Both the TLE2061ACD and TLE2061CDR have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture-related handling restrictions. Standard electronic component storage and handling practices are sufficient.

Q: Are both parts compliant with environmental and regulatory requirements?

A: Yes. Both the TLE2061ACD and TLE2061CDR are ROHS3 compliant and REACH unaffected. Both carry ECCN classification EAR99 and HTSUS code 8542.33.0001.
