Substitution of the TLE2061CD is determined by the following critical parameters:

Primary Substitution Criteria:

Amplifier Type: J-FET (low input bias current requirement)
Package / Case: 8-SOIC form factor (0.154", 3.90mm Width)
Mounting Type: Surface Mount
Voltage - Supply Span: Minimum 7 V, Maximum 36 V
Operating Temperature: Minimum 0°C, Maximum 70°C (or extended range)

Substitution Categories:

Direct Equivalent (Same Circuit Count): TLE2061CDR is the tape-and-reel packaging variant of the same base product (TLE2061) with identical electrical specifications and Last Time Buy status mitigation.
Dual-Circuit J-FET Alternatives: OP282GSZ-REEL, AD8682ARZ-REEL, and TL072BIYDT provide J-FET amplification in dual-circuit configurations. These parts maintain J-FET input characteristics but require circuit design accommodation for the additional circuit and may offer enhanced performance parameters (higher slew rate, gain bandwidth product).
General-Purpose Alternatives: AP4310AMTR-G1 and AS358AMTR-E1/AS358AMTR-G1 provide dual-circuit general-purpose amplification in 8-SOIC packaging. These parts sacrifice J-FET input characteristics (higher input bias current: 20 nA vs. 4 pA) but offer lower supply voltage minimums (3 V) and extended temperature ranges.
J-FET Alternatives with Enhanced Specifications: TL062ACDT and TL082BIYDT provide J-FET amplification with automotive-grade qualification (AEC-Q100) and extended temperature ranges, suitable for demanding environments.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): Select TLE2061CDR. This part is the tape-and-reel packaging variant of the TLE2061 base product with identical electrical performance, supply voltage range (7 V to 36 V), and operating temperature (0°C to 70°C). Product status is Active, ensuring long-term availability. Both parts are ROHS3 compliant with MSL 1 rating.

For Extended Temperature Range Applications: Select TL072BIYDT or TL082BIYDT. Both are J-FET dual-circuit amplifiers with automotive-grade qualification (AEC-Q100) and extended operating temperature ranges (-40°C to 125°C and -40°C to 105°C respectively). These parts maintain J-FET input characteristics and 8-SOIC packaging. Circuit design must accommodate dual-circuit configuration.

For Low-Supply-Voltage Applications: Select AP4310AMTR-G1 or AS358AMTR-E1/AS358AMTR-G1. These general-purpose dual-circuit amplifiers operate from 3 V minimum supply voltage, compared to 7 V for TLE2061CD. Trade-off: input bias current increases to 20 nA (vs. 4 pA for J-FET types). Both are ROHS3 compliant and Active status.

For Enhanced Performance (Higher Slew Rate and Bandwidth): Select OP282GSZ-REEL or AD8682ARZ-REEL. Both are J-FET dual-circuit amplifiers with slew rates of 9 V/µs (vs. 3.4 V/µs) and gain bandwidth products of 4 MHz and 3.5 MHz respectively. Operating temperature range extends to -40°C to 85°C. Both are ROHS3 compliant and Active status.

For Matched Slew Rate and Bandwidth (Single-Circuit Requirement): No single-circuit substitute with identical slew rate (3.4 V/µs) and gain bandwidth product (2 MHz) is available in the provided list. TLE2061CDR remains the only direct equivalent.

All recommended substitutes are ROHS3 compliant, REACH unaffected, and carry ECCN EAR99 classification, matching the compliance profile of TLE2061CD.

Frequently Asked Questions (FAQ)

Q1: Can TLE2061CDR be used as a direct replacement for TLE2061CD?

A: Yes. TLE2061CDR is the tape-and-reel packaging variant of the same TLE2061 base product. Electrical specifications, supply voltage range (7 V to 36 V), operating temperature (0°C to 70°C), and 8-SOIC package are identical. The only difference is packaging format (Tape & Reel vs. Tube). Product status is Active, providing supply continuity.

Q2: Why would I select a dual-circuit amplifier as a substitute for a single-circuit device?

A: Dual-circuit amplifiers (OP282GSZ-REEL, AD8682ARZ-REEL, TL072BIYDT, TL082BIYDT) provide J-FET input characteristics in a single 8-SOIC package. If your application requires two amplifier channels, a dual-circuit part reduces component count and board space. If only one channel is needed, the second circuit remains unused. All maintain 8-SOIC packaging and 36 V maximum supply voltage compatibility.

Q3: What is the trade-off when selecting AP4310AMTR-G1 or AS358AMTR-E1?

A: These general-purpose amplifiers sacrifice J-FET input characteristics (input bias current increases from 4 pA to 20 nA) but offer lower minimum supply voltage (3 V vs. 7 V) and extended temperature ranges. Select these only if your application does not require ultra-low input bias current and can benefit from lower supply voltage operation.

Q4: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the compliance status of TLE2061CD. Moisture Sensitivity Level (MSL) ratings vary: TLE2061CD, TLE2061CDR, OP282GSZ-REEL, OP282GSZ, and TL062ACDT carry MSL 1 (Unlimited); TL072BIYDT and TL082BIYDT carry MSL 1; AP4310AMTR-G1 and AS358AMTR-G1 carry MSL 3 (168 Hours).

Q5: Can I use TL062ACDT as a substitute?

A: TL062ACDT is a J-FET dual-circuit amplifier in 8-SOIC packaging with identical operating temperature range (0°C to 70°C) and supply voltage span (6 V to 36 V minimum, compatible with 7 V to 36 V requirement). However, slew rate (3.5 V/µs) and gain bandwidth product (1 MHz) differ from TLE2061CD (3.4 V/µs and 2 MHz). Input bias current is 30 nA (vs. 4 pA), representing a significant trade-off. Select only if application tolerates these parameter differences.

Q6: What is the inventory status of substitute parts?

A: TLE2061CDR has 12,600 units in stock (Active status). OP282GSZ-REEL has 18,270 units. AD8682ARZ-REEL has 3,400 units. TL072BIYDT has 3,600 units. TL082BIYDT has 12,000 units. AP4310AMTR-G1 has 888,300 units (highest availability). AS358AMTR-E1 has 300,200 units. AS358AMTR-G1 has 24,300 units. All are in Active status except TLE2061CD (Last Time Buy).

Q7: Do all substitute parts use the same 8-SOIC package?

A: Yes. All substitute parts use 8-SOIC (0.154", 3.90mm Width) surface mount packaging, ensuring PCB layout compatibility with TLE2061CD. Supplier device package designations may vary slightly (8-SOIC vs. 8-SO), but physical dimensions and pin assignments are equivalent for this package family.

Q8: Which substitute offers the best performance improvement?

A: TL072BIYDT and TL082BIYDT offer the highest slew rate (16 V/µs vs. 3.4 V/µs) and gain bandwidth product (4 MHz vs. 2 MHz). Both include automotive-grade qualification (AEC-Q100) and extended temperature ranges. Trade-off: input bias current increases to 20 pA, and supply current increases to 1.4 mA. Select for high-speed, high-performance applications.
