TL034ACN Equivalent & Substitute Parts

Part Overview

The TL034ACN is a J-FET input operational amplifier manufactured by Texas Instruments, configured as a 4-circuit integrated circuit in a 14-DIP through-hole package. This device is classified as Last Time Buy, indicating discontinued production with limited remaining inventory. The TL034ACN serves applications requiring low input bias current and stable offset voltage characteristics across the 0°C to 70°C operating temperature range. Alternative equivalent parts are necessary due to product status transition and packaging availability considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL034ACN is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier Type: J-FET input configuration
• Number of Circuits: 4 independent amplifier stages
• Slew Rate: 5.1 V/µs minimum
• Gain Bandwidth Product: 1.1 MHz minimum
• Current - Input Bias: 2 pA maximum
• Voltage - Input Offset: 580 µV maximum
• Voltage - Supply Span: 10 V to 30 V range
• Operating Temperature: 0°C to 70°C minimum coverage
• Current - Output / Channel: 40 mA minimum

Mechanical Equivalence Criteria:

• Package / Case: 14-DIP (0.300", 7.62mm) for direct socket compatibility
• Mounting Type: Through Hole

Compliance Criteria:

• RoHS3 Compliant status

Substitutes are identified based on identical electrical performance within specified tolerances and compatible packaging for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

TL034ACDR (Texas Instruments, Surface Mount Alternative):

The TL034ACDR maintains identical electrical specifications to the TL034ACN, including slew rate of 5.1 V/µs, gain bandwidth product of 1.1 MHz, input bias current of 2 pA, and input offset voltage of 580 µV. This part is manufactured by the same supplier and carries Active product status with significantly higher inventory availability (20,828 units). The TL034ACDR differs only in packaging format: 14-SOIC surface mount versus 14-DIP through-hole. Selection of this substitute requires PCB redesign for surface-mount assembly. ROHS3 compliance and REACH unaffected status are maintained.

LT1465CN (Analog Devices Inc., Through-Hole Alternative):

The LT1465CN provides through-hole 14-DIP packaging identical to the TL034ACN, enabling direct socket compatibility without PCB modification. This part is manufactured by Analog Devices Inc. and maintains Active product status. Electrical performance differs in the following parameters: slew rate of 0.9 V/µs (versus 5.1 V/µs), input bias current of 0.5 pA (superior to 2 pA), and supply current of 145 µA per 4 channels (versus 870 µA). The LT1465CN demonstrates lower power consumption and superior input bias current characteristics. Gain bandwidth product of 1.0 MHz and input offset voltage of 600 µV remain within acceptable tolerance. ROHS3 compliance and REACH unaffected status are maintained.

Selection between these substitutes depends on application requirements: TL034ACDR for high-speed applications with surface-mount capability, or LT1465CN for direct socket replacement with reduced power consumption.

Frequently Asked Questions (FAQ)

Q: Can the TL034ACDR directly replace the TL034ACN in existing designs?

A: Electrical substitution is direct; however, the TL034ACDR uses 14-SOIC surface-mount packaging versus the 14-DIP through-hole package of the TL034ACN. Direct socket replacement is not possible without PCB redesign and assembly process modification.

Q: What are the key differences between TL034ACDR and LT1465CN?

A: Both are 4-circuit J-FET amplifiers with 14-pin packages and identical supply voltage ranges (10 V to 30 V). The TL034ACDR maintains identical slew rate (5.1 V/µs) and input bias current (2 pA) to the TL034ACN. The LT1465CN offers lower slew rate (0.9 V/µs), superior input bias current (0.5 pA), and significantly reduced supply current (145 µA versus 870 µA). Packaging differs: TL034ACDR is surface mount (14-SOIC), while LT1465CN is through-hole (14-DIP).

Q: Is the LT1465CN suitable for high-speed applications?

A: The LT1465CN slew rate of 0.9 V/µs is lower than the TL034ACN specification of 5.1 V/µs. Applications requiring high-speed signal processing should retain the TL034ACDR or original TL034ACN. The LT1465CN is appropriate for applications where slew rate is not a limiting factor and power consumption reduction is beneficial.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both TL034ACDR and LT1465CN are ROHS3 Compliant and REACH Unaffected, matching the compliance status of the TL034ACN.

Q: What is the inventory status of these substitutes?

A: The TL034ACN is Last Time Buy status with 4,100 units available. The TL034ACDR is Active status with 20,828 units in stock. The LT1465CN is Active status with 1,425 units available. For long-term supply assurance, the TL034ACDR offers the highest inventory availability.

Q: Can the LT1465CN be used as a direct socket replacement?

A: Yes. The LT1465CN uses identical 14-DIP (0.300", 7.62mm) through-hole packaging and mounting type as the TL034ACN, enabling direct socket replacement without PCB modification. Electrical performance differences must be evaluated for specific application requirements.
