Substitute Part Grouping Explanation

Substitution of the TL064ACDRE4 is determined by the following critical parameters: amplifier type (J-FET), number of circuits (4), package type (14-SOIC), slew rate (3.5 V/µs), gain bandwidth product (1 MHz), input bias current (30 pA), input offset voltage (3 mV), supply current (200 µA per 4 channels), and supply voltage range (10 V to 30 V minimum and maximum).

Substitute parts are grouped into two categories:

Direct Equivalents (TL064 Series): Parts that maintain identical electrical specifications and J-FET amplifier topology. These include TL064ACDR (Texas Instruments, active product status) and TL064ACDT (STMicroelectronics, active product status). Both operate within the same supply voltage range and deliver equivalent performance characteristics.

Upgraded Alternatives (Enhanced Performance): Parts that exceed the baseline specifications while maintaining J-FET input architecture and four-circuit configuration. The TL064IDT (STMicroelectronics) extends the operating temperature range to -40°C ~ 105°C. The LF247DT and LF347DT series offer higher slew rates (16 V/µs), increased gain bandwidth product (4 MHz), and improved output current capability (40 mA per channel), with extended supply voltage specifications.

General Purpose Alternatives: Parts that substitute based on four-circuit configuration and 14-SOIC packaging but employ general purpose amplifier topology rather than J-FET input. These include LM124DT, LM224ADT, LM224D, and LM224DR2G. These alternatives are suitable only when J-FET input characteristics are not functionally required.

Frequently Asked Questions (FAQ)

Q: Can TL064ACDT be used as a direct replacement for TL064ACDRE4?

A: Yes. TL064ACDT maintains identical J-FET amplifier specifications, slew rate (3.5 V/µs), gain bandwidth product (1 MHz), input bias current (30 pA), and input offset voltage (3 mV). The primary difference is extended supply voltage range (6 V to 36 V versus 10 V to 30 V), which provides broader application compatibility. Both are packaged in 14-SOIC format and are ROHS3 compliant.

Q: What is the difference between TL064ACDR and TL064ACDT?

A: Both parts are electrically identical J-FET amplifiers with matching specifications. The difference is manufacturer: TL064ACDR is manufactured by Texas Instruments, while TL064ACDT is manufactured by STMicroelectronics. TL064ACDT offers extended supply voltage range (6 V to 36 V) compared to TL064ACDR (10 V to 30 V). Packaging format differs: TL064ACDR is supplied in Tape & Reel, while TL064ACDT is supplied in Tape & Reel with higher inventory availability (12,900 units).

Q: When should I select LF347DT instead of TL064ACDT?

A: Select LF347DT when the application requires higher slew rate (16 V/µs versus 3.5 V/µs) or increased gain bandwidth product (4 MHz versus 1 MHz). LF347DT also provides higher output current capability (40 mA per channel). Both maintain J-FET input architecture and four-circuit configuration in 14-SOIC packaging. LF347DT is suitable for applications demanding faster signal response and higher output drive capability.

Q: Are general purpose amplifiers (LM224 series) compatible with TL064ACDRE4 applications?

A: General purpose amplifiers are compatible only when J-FET input characteristics are not functionally required. The LM224 series uses general purpose amplifier topology rather than J-FET input, resulting in significantly higher input bias current (20 nA to 90 nA versus 30 pA). Applications requiring ultra-low input bias current, high input impedance, or low input offset current must use J-FET input devices (TL064 or LF347 series).

Q: What is the advantage of TL064IDT over TL064ACDT?

A: TL064IDT extends the operating temperature range to -40°C ~ 105°C, compared to TL064ACDT at 0°C ~ 70°C. Both maintain identical J-FET input specifications and electrical performance. TL064IDT is required for applications operating outside the 0°C ~ 70°C range. Both are packaged in 14-SOIC format and are ROHS3 compliant.

Q: Is packaging format interchangeable between substitute parts?

A: All substitute parts listed are packaged in 14-SOIC (0.154", 3.90mm Width) surface mount format, maintaining mechanical and electrical compatibility. Packaging format variations (Tape & Reel, Cut Tape & Digi-Reel, Tube) affect handling and supply chain logistics but do not affect circuit performance or PCB assembly compatibility.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts are ROHS3 compliant, carry Moisture Sensitivity Level 1 (Unlimited), and maintain REACH Unaffected status. All parts are classified under ECCN EAR99 and HTSUS 8542.33.0001. These certifications ensure regulatory compliance for industrial, commercial, and consumer applications.
