Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL064INSR is determined by the following critical parameters: amplifier type (J-FET input architecture), number of circuits (4), slew rate (3.5 V/µs), gain bandwidth product (1 MHz), input bias current (30 pA), input offset voltage (3 mV), supply current per channel (200 µA), output current per channel (20 mA), supply voltage range (10 V to 30 V minimum), operating temperature range (-40°C to 85°C minimum), and surface mount packaging in 14-SOIC configuration.

Substitute parts are grouped into two categories:

Category 1: Direct J-FET Equivalents (TL064 Base Product Family) Parts maintaining identical J-FET amplifier architecture, 4-circuit configuration, and electrical specifications. These include TL064IDR, TL064BCD, TL064ACDT, TL064CD, TL064CDT, and TL064IDT. Variations exist in packaging format (Tape & Reel, Tube, Cut Tape), temperature rating, and supply voltage range extensions. All maintain the core 3.5 V/µs slew rate and 1 MHz gain bandwidth product.

Category 2: Functional Alternative (MC3403DR2G) The MC3403DR2G from onsemi is a general-purpose 4-circuit amplifier with differential output configuration. While not J-FET input, it provides functional substitution for applications where input bias current tolerance is less critical. This part operates across a wider supply voltage range (3 V to 36 V) and extended temperature capability but exhibits different electrical characteristics including higher input bias current (200 nA) and lower slew rate (0.6 V/µs).

Engineering Selection Recommendations

For Direct Replacement (J-FET Architecture Required):

Select from the TL064 family equivalents when the application requires J-FET input characteristics, specifically the 30 pA input bias current specification. Among active status parts, TL064IDR (Texas Instruments, 35,100 units in stock) provides the closest electrical match with identical temperature range (-40°C to 85°C) and supply voltage specifications (10 V to 30 V). TL064IDT (STMicroelectronics, 16,553 units) extends the upper temperature rating to 105°C and broadens supply voltage range to 6 V to 36 V, suitable for extended industrial applications.

For applications operating within 0°C to 70°C temperature range, TL064ACDT, TL064CD, and TL064CDT (all STMicroelectronics, combined inventory 42,360 units) offer active product status with extended supply voltage range (6 V to 36 V). These parts are suitable for cost-optimized designs where the narrower temperature range is acceptable.

For Functional Substitution (General Purpose Alternative):

The MC3403DR2G (onsemi, 20,100 units in stock) serves as a functional alternative only when input bias current tolerance can be relaxed from 30 pA to 200 nA. This part is appropriate for applications where low input bias current is not a critical design parameter. The MC3403DR2G provides superior supply voltage flexibility (3 V to 36 V) and higher output current capability (30 mA per channel versus 20 mA), but exhibits reduced slew rate (0.6 V/µs versus 3.5 V/µs) and significantly higher supply current consumption (2.8 mA versus 200 µA per 4 channels).

Compliance and Certification:

All substitute parts maintain ROHS3 compliance, MSL Level 1 (unlimited moisture sensitivity), and REACH unaffected status, ensuring regulatory compatibility with the original TL064INSR specification.

Frequently Asked Questions (FAQ)

Q1: Can TL064IDR directly replace TL064INSR in existing designs?

A: Yes. TL064IDR maintains identical electrical specifications including J-FET input architecture, 3.5 V/µs slew rate, 1 MHz gain bandwidth product, 30 pA input bias current, and -40°C to 85°C operating temperature range. The primary difference is packaging format: TL064IDR is supplied in Cut Tape & Digi-Reel format versus Tape & Reel for TL064INSR. Both are surface mount 14-SOIC packages with compatible pinouts.

Q2: What are the key differences between TL064 variants from different manufacturers?

A: Texas Instruments TL064IDR and STMicroelectronics TL064ACDT, TL064CD, TL064CDT, and TL064IDT all maintain the core J-FET amplifier architecture and 1 MHz gain bandwidth product. STMicroelectronics variants extend the minimum supply voltage from 10 V to 6 V and maximum supply voltage from 30 V to 36 V. TL064IDT additionally extends the upper operating temperature to 105°C. All variants maintain 30 pA input bias current and 3.5 V/µs slew rate.

Q3: Is MC3403DR2G suitable as a substitute for TL064INSR?

A: MC3403DR2G is a functional alternative only for applications where J-FET input characteristics are not mandatory. The MC3403DR2G uses general-purpose amplifier architecture with 200 nanoampere input bias current (versus 30 picoampere for TL064INSR), significantly lower slew rate (0.6 V/µs versus 3.5 V/µs), and higher supply current consumption (2.8 mA versus 200 µA per 4 channels). It is not recommended for precision low-bias-current applications or high-speed signal processing.

Q4: Which substitute part offers the widest operating temperature range?

A: TL064IDT (STMicroelectronics) provides the widest operating temperature range of -40°C to 105°C, compared to TL064INSR at -40°C to 85°C. This extended upper temperature rating is suitable for automotive and industrial applications requiring operation in elevated ambient conditions.

Q5: What packaging options are available for TL064 substitutes?

A: TL064 equivalents are available in three packaging formats: Tape & Reel (TL064INSR, TL064ACDT), Tube (TL064BCD, TL064CD), and Cut Tape & Digi-Reel (TL064IDR, TL064CDT, TL064IDT). All use 14-SOIC surface mount configuration. Selection depends on production volume and assembly line requirements. Tape & Reel and Cut Tape formats are suitable for automated pick-and-place assembly; Tube packaging is appropriate for lower-volume manual assembly.

Q6: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (TL064IDR, TL064BCD, TL064ACDT, TL064CD, TL064CDT, TL064IDT, and MC3403DR2G) are ROHS3 compliant with MSL Level 1 (unlimited moisture sensitivity) and REACH unaffected status, ensuring regulatory compatibility with the original TL064INSR.

Q7: Which substitute offers the best inventory availability?

A: TL064IDR (Texas Instruments) provides the highest inventory level at 35,100 units in stock, followed by TL064CDT (STMicroelectronics) at 18,160 units and MC3403DR2G (onsemi) at 20,100 units. For applications requiring immediate supply chain security, TL064IDR is the recommended choice.
