TL064CNSR Equivalent & Substitute Parts Reference

Part Overview

The TL064CNSR is a J-FET input operational amplifier containing four independent circuits in a 14-SOIC surface mount package, manufactured by Texas Instruments. This device is classified as Last Time Buy, indicating discontinued production with limited inventory availability. The TL064CNSR operates across a supply voltage range of 10V to 30V with low input bias current of 30 pA and is suitable for applications requiring high input impedance and low noise characteristics. Identification of equivalent and substitute parts is necessary due to product discontinuation and to ensure design continuity and long-term component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL064CNSR is determined by 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), supply voltage range compatibility, and surface mount 14-SOIC packaging.

The substitute parts identified are grouped into two categories:

Category 1: Direct J-FET Equivalents Parts TL064CDR (Texas Instruments) and TL064CD (STMicroelectronics) maintain identical J-FET amplifier architecture, electrical specifications, and functional performance. These parts are pin-compatible and electrically interchangeable with the TL064CNSR, with differences limited to packaging format and supply voltage span extensions.

Category 2: Functional Alternative Part MC3403DR2G (onsemi) provides a general-purpose four-circuit amplifier in 14-SOIC packaging with differential output configuration. While this part shares the same circuit count, package type, and operating temperature range, it differs in amplifier type (general purpose versus J-FET), slew rate (0.6 V/µs versus 3.5 V/µs), input bias current (200 nA versus 30 pA), and supply voltage range (3V to 36V versus 10V to 30V). This part is suitable only for applications where J-FET input characteristics are not required.

Engineering Selection Recommendations

For Direct Replacement (Preferred): TL064CDR and TL064CD are recommended as primary substitutes for the TL064CNSR. Both parts maintain J-FET input architecture and identical electrical performance specifications. TL064CDR (Texas Instruments, Active status) offers the highest inventory availability at 55,100 pieces and maintains the same manufacturer lineage as the original part. TL064CD (STMicroelectronics, Active status) provides an alternative source with 11,300 pieces in stock and extended minimum supply voltage capability (6V versus 10V). Both parts are ROHS3 compliant and carry MSL rating of 1 (Unlimited), ensuring compatibility with standard manufacturing processes.

For Functional Alternative (When J-FET Input Not Required): MC3403DR2G may be considered only in applications where J-FET input characteristics are not essential. This part introduces significant differences: reduced slew rate (0.6 V/µs versus 3.5 V/µs), substantially higher input bias current (200 nA versus 30 pA), increased supply current consumption (2.8 mA versus 200 µA per four channels), and extended supply voltage range (3V to 36V). The MC3403DR2G is suitable for general-purpose amplification in low-speed applications with relaxed input impedance requirements. Active product status and high inventory (20,100 pieces) support long-term availability.

Compliance and Certification: All substitute parts maintain ROHS3 compliance, MSL rating of 1 (Unlimited), and EAR99 export classification, ensuring regulatory and manufacturing process compatibility with the original TL064CNSR specification.

Frequently Asked Questions (FAQ)

Q: Can TL064CDR be used as a direct replacement for TL064CNSR in all applications? A: Yes. TL064CDR maintains identical J-FET amplifier architecture, electrical specifications (slew rate, gain bandwidth product, input bias current, offset voltage), and operating temperature range. The primary difference is packaging format (14-SOIC with 3.90mm width versus 5.30mm width) and identical supply voltage span (10V to 30V). PCB layout accommodation for the narrower package width is required.

Q: What are the key differences between TL064CD and TL064CDR? A: Both parts are J-FET equivalents with identical electrical performance. The primary differences are manufacturer (STMicroelectronics versus Texas Instruments), packaging format (Tube versus Cut Tape/Digi-Reel), and minimum supply voltage specification (6V versus 10V). TL064CD supports operation at lower minimum supply voltages, providing additional design flexibility.

Q: When is MC3403DR2G an acceptable substitute? A: MC3403DR2G is acceptable only when J-FET input characteristics are not required. Applications requiring high input impedance, extremely low input bias current (30 pA), or fast slew rate (3.5 V/µs) must use TL064CDR or TL064CD. MC3403DR2G is suitable for general-purpose amplification, transimpedance applications with moderate input impedance requirements, and designs operating from lower supply voltages (3V minimum).

Q: Are there package compatibility concerns when substituting TL064CNSR? A: Yes. The TL064CNSR uses a 14-SOIC package with 5.30mm width, while TL064CDR and TL064CD use 14-SOIC packages with 3.90mm width. Both are surface mount 14-pin SOIC packages with identical pin assignments, but PCB footprint dimensions differ. Verify PCB layout accommodates the narrower package width before implementation.

Q: What is the inventory status for each substitute part? A: TL064CDR (Texas Instruments) has the highest availability at 55,100 pieces. TL064CD (STMicroelectronics) has 11,300 pieces in stock. MC3403DR2G (onsemi) has 20,100 pieces available. The original TL064CNSR has 2,415 pieces remaining as Last Time Buy inventory.

Q: Do all substitute parts meet the same compliance requirements? A: Yes. TL064CDR, TL064CD, and MC3403DR2G are all ROHS3 compliant, carry MSL rating of 1 (Unlimited), are REACH unaffected, and share EAR99 export classification with the TL064CNSR. All parts are suitable for standard manufacturing processes without additional compliance considerations.
