TL064CP Equivalent & Substitute Parts Reference

Part Overview

The TL064CP is a J-FET input operational amplifier containing four independent circuits in a 14-pin DIP package, manufactured by Texas Instruments. This device is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing system support and new designs requiring similar functionality.

The TL064CP 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. Its J-FET input stage provides high input impedance with 30 pA input bias current, making it suitable for precision analog signal processing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TL064CP are identified based on strict electrical and mechanical compatibility criteria. The primary substitution logic follows these parameters:

Critical Matching Parameters:

• Amplifier Type: J-FET input configuration
• Package / Case: 14-DIP form factor
• Mounting Type: Through Hole
• Gain Bandwidth Product: 1 MHz
• Voltage - Input Offset: 3 mV
• Operating Temperature Range: Minimum 0°C to 70°C coverage

Substitution Categories:

Direct Equivalent (Same Circuit Count): Parts maintaining 4 independent circuits with identical electrical specifications and 14-DIP packaging.

Functional Equivalent (Different Circuit Count): Parts with reduced circuit count (2 circuits) but matching core electrical parameters, requiring multiple devices for full replacement in 4-circuit applications.

Enhanced Specification Equivalent: Parts with improved specifications (lower input bias current, higher supply voltage capability, active product status) while maintaining core functionality and package compatibility.

Parameter Comparison

Engineering Selection Recommendations

TL064CN (onsemi): Direct electrical and mechanical equivalent to TL064CP. Maintains identical circuit count (4), slew rate (3.5V/µs), supply voltage range (10V to 30V), and 14-DIP package configuration. Product status is obsolete. Selection is appropriate for direct replacement in existing designs where component availability and inventory levels are primary considerations. RoHS non-compliance status matches the original part.

LF444CN/NOPB (Texas Instruments): Active product status provides long-term availability assurance. Maintains 4-circuit configuration and 14-DIP package. Electrical differences include reduced input bias current (10 pA versus 30 pA), reduced slew rate (1V/µs versus 3.5V/µs), increased supply current (600µA versus 200µA per 4 channels), and reduced output current per channel (14 mA versus 20 mA). Supply voltage capability extends to 36V. ROHS3 compliance supports modern manufacturing and environmental requirements. Selection is appropriate for new designs requiring long-term component support and regulatory compliance, provided application timing and power budget accommodate the electrical differences.

TL062IP (Texas Instruments): Active product status with extended operating temperature range (-40°C to 85°C). Contains 2 circuits versus 4 circuits in the main part, requiring dual devices for equivalent circuit count. Maintains matching slew rate (3.5V/µs), input bias current (30 pA), and supply voltage range (10V to 30V). Package is 8-DIP. ROHS3 compliance and active status support modern applications. Selection is appropriate for applications where dual 2-circuit devices are acceptable or where extended temperature range is required.

Frequently Asked Questions (FAQ)

Q: Can TL064CN be used as a direct replacement for TL064CP?

A: Yes. TL064CN provides direct electrical and mechanical compatibility. Both devices contain 4 J-FET circuits in 14-DIP packages with identical slew rate (3.5V/µs), gain bandwidth product (1 MHz), input bias current (30 pA), and supply voltage range (10V to 30V). Pin configuration and functional performance are equivalent.

Q: What are the key differences between TL064CP and LF444CN/NOPB?

A: LF444CN/NOPB maintains 4-circuit configuration and 14-DIP packaging but differs in: input bias current (10 pA versus 30 pA), slew rate (1V/µs versus 3.5V/µs), supply current (600µA versus 200µA per 4 channels), output current per channel (14 mA versus 20 mA), and supply voltage maximum (36V versus 30V). LF444CN/NOPB is an active product with ROHS3 compliance.

Q: Why is TL062IP listed as a substitute if it has only 2 circuits?

A: TL062IP is listed as a functional equivalent for applications where circuit count can be accommodated through multiple devices or where only 2 circuits are required. It maintains core electrical parameters (J-FET type, 3.5V/µs slew rate, 1 MHz bandwidth, 30 pA input bias current) and supply voltage range. Active product status and extended temperature range (-40°C to 85°C) provide advantages for certain applications.

Q: Are there packaging differences between these substitutes?

A: TL064CP and TL064CN use 14-DIP packages. LF444CN/NOPB also uses 14-DIP. TL062IP uses 8-DIP packaging. All are through-hole mount types with 0.300" (7.62mm) pitch, compatible with standard DIP sockets and PCB layouts designed for these form factors.

Q: What is the impact of the slew rate difference between TL064CP and LF444CN/NOPB?

A: TL064CP has 3.5V/µs slew rate while LF444CN/NOPB has 1V/µs. Slew rate determines the maximum rate of voltage change at the output. Applications requiring high-speed signal processing or steep transient response may be affected. LF444CN/NOPB is suitable for applications where lower slew rate is acceptable or where signal bandwidth is limited.

Q: What is the significance of RoHS compliance status?

A: TL064CP and TL064CN are RoHS non-compliant. LF444CN/NOPB and TL062IP are ROHS3 compliant. RoHS compliance is required for products sold into regulated markets and reflects manufacturing processes free from specified hazardous substances. New designs should prioritize ROHS3-compliant alternatives where possible.

Q: Can TL062IP be used in applications designed for TL064CP?

A: TL062IP can be used only if the application circuit design accommodates 2-circuit devices instead of 4-circuit devices. Electrical parameters (J-FET input, 3.5V/µs slew rate, 1 MHz bandwidth, 30 pA input bias current, 10V to 30V supply range) are compatible. Extended operating temperature range (-40°C to 85°C) provides additional capability. Pin-to-pin compatibility does not exist due to different package sizes (8-DIP versus 14-DIP).

Q: What supply current differences should be considered?

A: TL064CP and TL064CN draw 200µA total for 4 channels (50µA per channel). LF444CN/NOPB draws 600µA total for 4 channels (150µA per channel). TL062IP draws 200µA total for 2 channels (100µA per channel). Applications with strict power budget constraints should account for these differences, particularly in battery-powered or low-power systems.
