TLE2061AID Equivalent & Substitute Parts

Part Overview

The TLE2061AID is a J-FET input operational amplifier manufactured by Texas Instruments, designed for low-noise, high-impedance signal processing applications. This device integrates one amplifier circuit in an 8-SOIC surface mount package and operates across a wide supply voltage range of 7V to 36V with an operating temperature range of -40°C to 85°C.

The TLE2061AID is classified as Last Time Buy, indicating discontinued production. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE2061AID is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Amplifier topology: J-FET input configuration
• Number of circuits: Single amplifier per package
• Package type: 8-SOIC surface mount form factor
• Slew rate: 3.4 V/µs minimum
• Gain bandwidth product: 2 MHz minimum
• Input bias current: 4 pA maximum
• Supply voltage range: 7V to 36V minimum span
• Operating temperature range: -40°C to 85°C minimum coverage
• Output current capability: 80 mA per channel minimum

The TLE2061IDR, manufactured by Texas Instruments in the Excalibur™ series, meets all primary substitution criteria. This part maintains identical electrical performance specifications and mechanical compatibility while differing only in packaging format (Tape & Reel versus Tube) and product status (Active versus Last Time Buy).

Parameter Comparison

Engineering Selection Recommendations

TLE2061IDR as Primary Substitute:

The TLE2061IDR is the manufacturer-recommended substitute for the TLE2061AID. Both parts are manufactured by Texas Instruments within the Excalibur™ series and share identical electrical specifications across all critical parameters. The TLE2061IDR maintains full compatibility with existing TLE2061AID designs without circuit modification.

The key distinction between these parts is packaging format and product lifecycle status. The TLE2061AID is supplied in Tube packaging and carries Last Time Buy status, indicating end-of-life production. The TLE2061IDR is supplied in Tape & Reel format and maintains Active product status with significantly higher inventory availability (12,700 pieces versus 1,040 pieces).

Both parts comply with ROHS3 regulations, carry MSL Level 1 (Unlimited) moisture sensitivity classification, and maintain REACH Unaffected status. No design changes, PCB modifications, or thermal management adjustments are required when transitioning from TLE2061AID to TLE2061IDR.

Compliance and Certification Alignment:

Both parts carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8542.33.0001), ensuring equivalent export control and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can TLE2061IDR directly replace TLE2061AID in existing designs?

A: Yes. The TLE2061IDR is electrically and mechanically identical to the TLE2061AID. No circuit modifications, PCB layout changes, or firmware updates are required. The parts are pin-compatible and functionally equivalent across all specified parameters.

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

A: Tube packaging (TLE2061AID) supplies components in plastic tubes suitable for manual handling and small-quantity applications. Tape & Reel packaging (TLE2061IDR) supplies components on continuous carrier tape wound on reels, optimized for automated assembly equipment and high-volume production. Both packaging formats contain identical die and internal circuitry.

Q: Why is TLE2061AID marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. Existing inventory will be depleted without replenishment. Customers requiring continued supply must transition to the TLE2061IDR or identify alternative solutions.

Q: Are there electrical performance differences between TLE2061AID and TLE2061IDR?

A: The parts are electrically equivalent with one minor specification variance: input offset voltage is specified at 500 µV (TLE2061AID) versus 600 µV (TLE2061IDR). This 100 µV difference falls within normal manufacturing tolerance ranges and does not affect circuit functionality in standard applications.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both TLE2061AID and TLE2061IDR carry identical ROHS3 compliance, MSL Level 1 moisture sensitivity rating, REACH Unaffected status, and export control classifications (ECCN: EAR99).

Q: What is the current inventory status for each part?

A: TLE2061AID inventory is limited to 1,040 pieces in stock. TLE2061IDR inventory is significantly higher at 12,700 pieces. For new designs or long-term supply requirements, TLE2061IDR is the recommended selection.

Q: Are there any thermal or mechanical considerations when substituting these parts?

A: No. Both parts use identical 8-SOIC surface mount packages with matching thermal characteristics, pin assignments, and mechanical dimensions (0.154" width, 3.90mm). PCB footprints, thermal vias, and mounting hardware require no modification.
