TL064INS Equivalent & Substitute Parts

Part Overview

The TL064INS is a J-FET input operational amplifier containing four independent circuits in a 14-SO surface mount package, manufactured by Texas Instruments. This device is classified as Last Time Buy, indicating discontinued production with limited remaining inventory of 947 pieces. The TL064INS operates across a wide supply voltage range of 10V to 30V and maintains low input bias current of 30 pA, making it suitable for precision analog signal processing applications requiring high input impedance.

Equivalent and substitute parts are necessary due to the Last Time Buy status of the TL064INS. Alternative devices with identical or compatible electrical and mechanical specifications ensure design continuity and long-term component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL064INS is determined by electrical and mechanical compatibility across the following critical parameters: amplifier type (J-FET input architecture), number of circuits (4 independent amplifiers), 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 (10V to 30V minimum and maximum), operating temperature range (-40°C to 85°C), and surface mount packaging in 14-SOIC configuration.

Substitute parts are grouped into two categories:

Direct Equivalents (Identical Specifications): Parts that maintain all electrical parameters and operating conditions of the TL064INS, differing only in packaging format or manufacturer source.

Compatible Alternatives (Functional Equivalents): Parts that satisfy the core functional requirements but may differ in specific parameters such as amplifier type classification, slew rate, input bias current, or operating temperature range. These alternatives are suitable only when application requirements permit parameter variation.

Parameter Comparison

Engineering Selection Recommendations

TL064IDR (Texas Instruments): This part is the primary direct equivalent to the TL064INS. It maintains identical electrical specifications including J-FET amplifier type, 3.5 V/µs slew rate, 30 pA input bias current, and -40°C to 85°C operating temperature range. The TL064IDR differs only in packaging format (Cut Tape & Digi-Reel versus Tube) and physical package dimensions (0.154" versus 0.209" width). This part is in Active product status with 35,100 units in stock, providing superior long-term availability. The TL064IDR is suitable for direct substitution in applications where the narrower package footprint (3.90mm versus 5.30mm) is compatible with PCB layout requirements. Both parts are ROHS3 compliant with MSL 1 rating.

TL064CD (STMicroelectronics): This part is a direct electrical equivalent to the TL064INS with identical J-FET amplifier type, 3.5 V/µs slew rate, 30 pA input bias current, and 20 mA output current per channel. The TL064CD differs in minimum supply voltage (6V versus 10V) and operating temperature range (0°C to 70°C versus -40°C to 85°C). This part is suitable for substitution only in applications operating within 6V to 30V supply range and 0°C to 70°C temperature limits. The TL064CD is in Active product status with 11,300 units in stock and maintains identical Tube packaging format. ROHS3 compliance and MSL 1 rating are maintained.

MC3403DR2G (onsemi): This part is a functional alternative with significant parameter differences. The MC3403DR2G is classified as General Purpose amplifier rather than J-FET input, resulting in substantially higher input bias current (200 nA versus 30 pA), higher supply current per channel (2.8 mA versus 200 µA), and lower slew rate (0.6 V/µs versus 3.5 V/µs). The operating temperature range is restricted to 0°C to 70°C. The MC3403DR2G is suitable for substitution only in applications where high input impedance is not critical and where the lower slew rate and higher power consumption are acceptable. This part offers wider supply voltage range (3V to 36V) and higher output current per channel (30 mA). The MC3403DR2G is in Active product status with 20,100 units in stock.

Frequently Asked Questions (FAQ)

Q: Can the TL064IDR be used as a direct replacement for the TL064INS?

A: The TL064IDR is electrically equivalent to the TL064INS with identical amplifier type, slew rate, input bias current, and operating temperature range. The primary difference is physical package width (3.90mm versus 5.30mm). Substitution is valid if PCB layout accommodates the narrower package footprint. Both parts maintain ROHS3 compliance and MSL 1 rating.

Q: What are the key limitations of using TL064CD as a substitute?

A: The TL064CD has a reduced minimum supply voltage of 6V (versus 10V for TL064INS) and restricted operating temperature range of 0°C to 70°C (versus -40°C to 85°C). Applications requiring operation below 6V supply voltage or outside the 0°C to 70°C temperature range cannot use the TL064CD. All other electrical parameters remain identical.

Q: Is the MC3403DR2G suitable for high-impedance input applications?

A: No. The MC3403DR2G has input bias current of 200 nA compared to 30 pA for the TL064INS, making it unsuitable for applications requiring very high input impedance. The MC3403DR2G is classified as General Purpose amplifier rather than J-FET input, resulting in approximately 6,700 times higher input bias current. This part is suitable only for applications where input impedance requirements are less stringent.

Q: What is the impact of slew rate differences between substitute parts?

A: The TL064INS and its direct equivalents (TL064IDR and TL064CD) have 3.5 V/µs slew rate. The MC3403DR2G has 0.6 V/µs slew rate, approximately 5.8 times slower. Applications requiring fast signal transitions or high-frequency operation may experience performance degradation with the MC3403DR2G. The lower slew rate limits the maximum rate of output voltage change.

Q: Are all substitute parts available in the same packaging format?

A: No. The TL064INS and TL064CD are supplied in Tube packaging, while TL064IDR and MC3403DR2G are supplied in Cut Tape & Digi-Reel format. Additionally, the TL064INS has a wider package body (5.30mm) compared to TL064IDR, TL064CD, and MC3403DR2G (3.90mm). PCB layout and assembly equipment compatibility must be verified before substitution.

Q: What is the supply current difference between substitute parts?

A: The TL064INS, TL064IDR, and TL064CD each draw 200 µA per channel (800 µA total for four channels). The MC3403DR2G draws 2.8 mA per channel (11.2 mA total for four channels), approximately 14 times higher. Applications with strict power consumption requirements should not use the MC3403DR2G.

Q: Can the TL064INS be used in applications requiring operation below 0°C?

A: Yes. The TL064INS operates from -40°C to 85°C. The TL064IDR maintains this temperature range. The TL064CD and MC3403DR2G are limited to 0°C to 70°C and cannot be used for sub-zero temperature applications.

Q: What compliance certifications are maintained across all substitute parts?

A: All parts (TL064INS, TL064IDR, TL064CD, and MC3403DR2G) are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level). All parts carry ECCN EAR99 classification and HTSUS code 8542.33.0001.
