TLE2061ID Equivalent & Substitute Parts

Part Overview

The TLE2061ID is a J-FET input operational amplifier manufactured by Texas Instruments in the Excalibur™ series. This single-circuit 8-SOIC surface mount device is designated as Last Time Buy, indicating discontinued production. The TLE2061ID provides low input bias current (4 pA) and low input offset voltage (600 µV) characteristics suitable for precision signal conditioning applications. Identification of equivalent and substitute parts is necessary due to product discontinuation and to support design flexibility across manufacturing batches and procurement channels.

The TLE2061IDR (Texas Instruments) is a direct equivalent, differing only in packaging format (Tape & Reel versus Tube). This part maintains identical electrical specifications and is the manufacturer-recommended substitute.

Parts AD8682ARZ, AD8682ARZ-REEL, and AD8682ARZ-REEL7 (Analog Devices) are J-FET amplifiers in 8-SOIC packages but contain two circuits instead of one. These parts exceed the electrical performance specifications of the TLE2061ID and are suitable for applications where dual-channel capability is acceptable or beneficial.

Parts AP4310AMTR-G1, AS358AMTR-E1, LM258AWDT, LM358AWDT, and LM358ADR2G are general-purpose amplifiers with different input topologies (not J-FET) and dual-circuit configurations. These parts are listed as cross-references but operate under different electrical characteristics and should be evaluated for specific application requirements.

Engineering Selection Recommendations

Direct Equivalent (Recommended for TLE2061ID Replacement):

TLE2061IDR is the manufacturer-recommended substitute. This part is produced by Texas Instruments with identical electrical and functional specifications. The only difference is packaging format: TLE2061IDR is supplied in Tape & Reel format while TLE2061ID is supplied in Tube format. Both parts are ROHS3 compliant, have MSL 1 rating, and are REACH unaffected. TLE2061IDR is in Active product status with 12,700 units in stock, providing long-term availability.

J-FET Amplifier Alternatives (Enhanced Performance):

AD8682ARZ, AD8682ARZ-REEL, AD8682ARZ-REEL7, and OP282GSZ are J-FET input amplifiers in 8-SOIC packages manufactured by Analog Devices. These parts exceed TLE2061ID specifications in slew rate (9 V/µs versus 3.4 V/µs), gain bandwidth product (3.5–4 MHz versus 2 MHz), and input offset voltage (200–350 µV versus 600 µV). All are ROHS3 compliant with MSL 1 rating and operating temperature range of -40°C to 85°C. These parts are suitable for applications requiring higher performance J-FET amplification. AD8682 variants contain two circuits; OP282GSZ also contains two circuits. Supply voltage minimum is 9 V for these parts, compared to 7 V for TLE2061ID.

General-Purpose Amplifier Cross-References:

AP4310AMTR-G1, AS358AMTR-E1, LM258AWDT, LM358AWDT, and LM358ADR2G are general-purpose amplifiers with bipolar input stages, not J-FET input stages. These parts are listed as cross-references but operate under fundamentally different electrical characteristics. All are ROHS3 compliant and in Active status. LM258AWDT and LM358AWDT are AEC-Q100 qualified automotive-grade parts. These parts are suitable only for applications where J-FET input characteristics are not required and where the lower input bias current and offset voltage specifications of J-FET devices are not critical.

Frequently Asked Questions (FAQ)

Q: Can TLE2061IDR be used as a direct replacement for TLE2061ID?

A: Yes. TLE2061IDR is the manufacturer-recommended equivalent. Both parts have identical electrical specifications, operating temperature range (-40°C to 85°C), supply voltage range (7–36 V), and 8-SOIC package. The difference is packaging format: TLE2061IDR is supplied in Tape & Reel format for automated assembly, while TLE2061ID is supplied in Tube format for manual handling.

Q: What is the key difference between TLE2061ID and AD8682ARZ?

A: TLE2061ID is a single-circuit J-FET amplifier, while AD8682ARZ is a dual-circuit J-FET amplifier. AD8682ARZ has superior performance specifications: slew rate of 9 V/µs (versus 3.4 V/µs), gain bandwidth product of 3.5 MHz (versus 2 MHz), and lower input offset voltage of 350 µV (versus 600 µV). However, AD8682ARZ requires a minimum supply voltage of 9 V, compared to 7 V for TLE2061ID. AD8682ARZ is suitable for applications requiring higher bandwidth and faster response.

Q: Are general-purpose amplifiers like LM258AWDT suitable replacements for TLE2061ID?

A: General-purpose amplifiers differ fundamentally from J-FET input amplifiers. LM258AWDT and similar parts use bipolar input stages, resulting in higher input bias current (20 nA versus 4 pA) and higher input offset voltage (1 mV versus 600 µV). These parts are suitable only for applications where the precision characteristics of J-FET input amplifiers are not required. Substitution should be evaluated on a circuit-specific basis.

Q: What is the significance of the 8-SOIC package specification?

A: The 8-SOIC (Small Outline Integrated Circuit) package is a surface mount form factor with 0.154-inch (3.90 mm) width. All listed substitute parts use the same 8-SOIC package, ensuring mechanical and electrical compatibility with existing PCB layouts and assembly processes. Package compatibility is a prerequisite for direct substitution.

Q: Why is TLE2061ID designated as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part. Existing inventory will be depleted, and no future production is planned. TLE2061IDR (Tape & Reel format) is the active replacement and should be used for new designs and long-term procurement planning.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed in this reference are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for electronic components in most jurisdictions.

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

A: Tube packaging is used for manual component handling and small-quantity assembly. Tape & Reel packaging is used for automated pick-and-place assembly equipment. Both formats contain the same electronic component; the difference is in handling and delivery method. Selection depends on assembly process requirements.
