TLE2061ACDRG4 Equivalent & Substitute Parts

Part Overview

The TLE2061ACDRG4 is a J-FET input operational amplifier manufactured by Texas Instruments, part of the Excalibur™ series. This single-circuit 8-SOIC surface mount device is designed for low-noise, high-impedance signal conditioning applications. The device is currently classified as Obsolete, making identification of equivalent substitute parts essential for design continuity and procurement planning. The TLE2061ACDRG4 operates across a wide supply voltage range (7V to 36V) with minimal input bias current (4 pA), making it suitable for precision analog applications requiring low input offset voltage and high input impedance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE2061ACDRG4 is determined by strict equivalence across all electrical and mechanical parameters. The primary substitution criterion is the maintenance of identical J-FET amplifier topology with matching performance specifications across slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current capability, and supply voltage range. The package type (8-SOIC surface mount) and operating temperature range (0°C to 70°C) must remain constant. Compliance certifications including RoHS3 status and moisture sensitivity level must be preserved.

The TLE2061ACD represents a direct functional equivalent, maintaining all electrical specifications while differing only in packaging format (Tube versus the original specification) and product lifecycle status (Last Time Buy versus Obsolete). Both devices share the identical base product number TLE2061 and are manufactured by Texas Instruments within the same Excalibur™ series.

Parameter Comparison

Engineering Selection Recommendations

The TLE2061ACD is a direct electrical and mechanical equivalent to the TLE2061ACDRG4. All performance-critical parameters are identical, including amplifier topology, frequency response, noise characteristics, supply voltage range, and thermal operating window. Both devices maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with modern manufacturing and environmental standards.

The primary distinction between these parts is product lifecycle status and packaging format. The TLE2061ACDRG4 is classified as Obsolete, indicating end-of-life status with no further manufacturing planned. The TLE2061ACD carries Last Time Buy status, indicating limited remaining inventory availability before discontinuation. The TLE2061ACD is supplied in Tube packaging, whereas the main part specification references Tape and Reel format. This packaging difference does not affect electrical performance or PCB assembly compatibility when using standard surface mount assembly equipment.

For new designs or production continuity, the TLE2061ACD should be selected as the primary substitute. Procurement should account for Last Time Buy status by securing adequate inventory for production requirements, as future availability cannot be guaranteed.

Frequently Asked Questions (FAQ)

Q: Can the TLE2061ACD be used as a direct replacement for the TLE2061ACDRG4 in existing designs?

A: Yes. The TLE2061ACD is electrically and mechanically equivalent. All performance parameters, supply voltage range, operating temperature range, package dimensions, and pin configuration are identical. No circuit modifications are required.

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

A: Tape and Reel packaging supplies components on continuous carrier tape suitable for automated pick-and-place assembly equipment. Tube packaging supplies components in plastic tubes, typically for manual handling or lower-volume assembly. Both formats contain identical components with identical electrical specifications. The choice between formats depends on assembly process requirements and volume.

Q: Why is the TLE2061ACDRG4 listed as Obsolete?

A: Obsolete status indicates that Texas Instruments has discontinued manufacturing of this specific part number variant. The underlying device technology remains current, but this particular configuration is no longer produced. The TLE2061ACD represents the available continuation of this product line.

Q: What does Last Time Buy status mean for the TLE2061ACD?

A: Last Time Buy indicates that the manufacturer has announced a final production run with a specified cutoff date for orders. After this date, the part will no longer be available from the manufacturer. Existing inventory may be available from authorized distributors, but supply is finite and will eventually be exhausted.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the TLE2061ACDRG4 and TLE2061ACD carry identical RoHS3 compliance status and REACH unaffected designation. Both maintain MSL Level 1 (Unlimited) moisture sensitivity rating. Compliance certifications are equivalent.

Q: Can I mix Tape and Reel and Tube packaging in the same production run?

A: Yes, from an electrical and functional perspective. However, assembly process considerations may apply. Tape and Reel format is optimized for continuous automated assembly, while Tube format may require manual feeding or different feeder equipment. Consult your assembly service provider regarding equipment compatibility and process efficiency.
