TL064BCP Equivalent & Substitute Parts

Part Overview

The TL064BCP is a J-FET input operational amplifier containing four independent circuits in a 14-pin DIP package. This device is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing applications and new designs. The TL064BCP operates across a supply voltage range of 10V to 30V with a slew rate of 3.5V/µs and a gain bandwidth product of 1 MHz, making it suitable for precision analog signal processing applications requiring low input bias current.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL064BCP is determined by the following critical parameters:

Primary Substitution Criteria:

• Amplifier type: J-FET input configuration
• Number of circuits: Four independent operational amplifiers
• Package type: 14-pin DIP with 0.300" (7.62mm) pitch
• Mounting method: Through-hole technology
• Operating temperature range: 0°C to 70°C
• Gain bandwidth product: 1 MHz
• Input offset voltage: 2 mV maximum

Secondary Compatibility Parameters:

• Supply voltage range compatibility
• Slew rate performance characteristics
• Input bias current specifications
• Supply current consumption per channel

The substitute parts identified maintain the core J-FET amplifier architecture and 14-DIP package format, ensuring mechanical and functional compatibility with existing circuit designs. Variations in slew rate, input bias current, and supply current reflect different manufacturing generations and performance grades within the same product family.

Engineering Selection Recommendations

TL064BCN (Direct Substitute): The TL064BCN is the active production equivalent of the TL064BCP. This part maintains identical electrical specifications including slew rate (3.5V/µs), input bias current (30 pA), and supply voltage range (10V to 30V). The TL064BCN is ROHS3 compliant and currently in active production status, making it the primary choice for direct replacement in existing designs. The packaging format and pin configuration are identical, requiring no circuit board modifications.

LF444ACN/NOPB (Functional Substitute): The LF444ACN/NOPB is a J-FET quad operational amplifier suitable for applications where the TL064BCP supply voltage range is not a limiting factor. This part exhibits superior input bias current performance (10 pA versus 30 pA) and operates across a wider supply voltage range (44V symmetric). The LF444ACN/NOPB is ROHS3 compliant and actively produced. Circuit design modifications are required to accommodate the different supply voltage specifications and increased supply current consumption (600µA versus 200µA total). The slew rate is reduced to 1V/µs, which may impact high-frequency signal processing applications.

Compliance Considerations: Both substitute parts are ROHS3 compliant, addressing environmental and regulatory requirements that the obsolete TL064BCP does not meet. Selection between TL064BCN and LF444ACN/NOPB depends on whether the existing circuit design operates within the 10V to 30V supply range (TL064BCN) or requires the extended 44V supply capability (LF444ACN/NOPB).

Frequently Asked Questions (FAQ)

Q: Can the TL064BCN be used as a direct replacement for the TL064BCP without circuit modifications?

A: Yes. The TL064BCN maintains identical electrical specifications and package format. No circuit board modifications are required for pin-to-pin substitution.

Q: What are the key differences between TL064BCN and LF444ACN/NOPB?

A: The primary differences are supply voltage range (TL064BCN: 10V to 30V; LF444ACN/NOPB: 44V), input bias current (TL064BCN: 30 pA; LF444ACN/NOPB: 10 pA), slew rate (TL064BCN: 3.5V/µs; LF444ACN/NOPB: 1V/µs), and total supply current (TL064BCN: 200µA; LF444ACN/NOPB: 600µA). Circuit design modifications are necessary when substituting with LF444ACN/NOPB.

Q: Is the LF444ACN/NOPB suitable for high-speed signal processing applications?

A: The LF444ACN/NOPB has a slew rate of 1V/µs compared to the TL064BCP's 3.5V/µs. Applications requiring faster signal transitions should use the TL064BCN instead.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both TL064BCN and LF444ACN/NOPB are ROHS3 compliant, whereas the TL064BCP is RoHS non-compliant.

Q: What is the impact of increased supply current in the LF444ACN/NOPB?

A: The LF444ACN/NOPB consumes 600µA total supply current compared to 200µA for the TL064BCP. Power supply design and thermal management considerations must be evaluated for applications with multiple devices or power-constrained systems.

Q: Can the TL064BCN and LF444ACN/NOPB be used interchangeably in the same circuit?

A: No. The different supply voltage ranges and electrical characteristics require circuit design verification before substitution. The TL064BCN is the appropriate choice for designs operating within the 10V to 30V range.

Q: What packaging options are available for these substitute parts?

A: All three parts (TL064BCP, TL064BCN, and LF444ACN/NOPB) are available in 14-pin DIP through-hole packages with 0.300" (7.62mm) pitch, ensuring mechanical compatibility.
