TL064ACP Equivalent & Substitute Parts

Part Overview

The TL064ACP is a J-FET input operational amplifier containing four independent circuits in a 14-DIP package. This device is classified as obsolete and is no longer in active production. The TL064ACP 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. Due to its obsolete status, identifying equivalent substitute parts is necessary for design continuity and component procurement in legacy system maintenance and new designs requiring compatible performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TL064ACP are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Critical Matching Parameters:

• Amplifier Type: J-FET input configuration
• Number of Circuits: 4 independent operational amplifiers
• Package Type: 14-DIP (0.300", 7.62mm) with Through Hole mounting
• Gain Bandwidth Product: 1 MHz
• Operating Temperature Range: 0°C ~ 70°C

Acceptable Variation Parameters:

• Slew Rate: Minimum 1V/µs (TL064ACP specifies 3.5V/µs)
• Current - Input Bias: Maximum 30 pA (lower values acceptable)
• Voltage - Input Offset: Maximum 3 mV (lower values acceptable)
• Voltage - Supply Span: Minimum 10V to Maximum 30V (wider ranges acceptable)
• Current - Supply: Up to 600µA per channel (higher values acceptable for same functionality)

The substitute parts TL064ACN and LF444ACN/NOPB meet these criteria with identical package configurations and circuit counts. Both maintain J-FET input characteristics and 1 MHz gain bandwidth product specifications.

Parameter Comparison

Engineering Selection Recommendations

TL064ACN (onsemi): This part provides direct electrical and mechanical equivalence to the TL064ACP. Identical slew rate (3.5V/µs), input bias current (30 pA), and supply voltage specifications ensure pin-for-pin compatibility. The TL064ACN is also classified as obsolete, making it suitable for legacy system repairs where exact performance matching is required. However, RoHS non-compliance status matches the original part.

LF444ACN/NOPB (Texas Instruments): This part is classified as active and ROHS3 compliant, providing long-term availability and regulatory compliance advantages. The LF444ACN/NOPB maintains identical package configuration, circuit count, and gain bandwidth product. Performance differences include lower input bias current (10 pA versus 30 pA), lower input offset voltage (2 mV versus 3 mV), and reduced slew rate (1V/µs versus 3.5V/µs). The supply voltage range is fixed at 44V, which exceeds the TL064ACP minimum requirement of 10V. Higher supply current consumption (600µA versus 200µA per channel) must be evaluated in power-constrained applications. The LF444ACN/NOPB is recommended for new designs requiring modern compliance certifications and extended component lifecycle.

Frequently Asked Questions (FAQ)

Q: Can TL064ACN be used as a direct replacement for TL064ACP?

A: Yes. The TL064ACN provides electrical and mechanical equivalence with identical slew rate, input bias current, voltage offset, and supply voltage specifications. Both parts use the 14-DIP package with Through Hole mounting. Pin configuration and functional performance are identical.

Q: What are the key differences between TL064ACP and LF444ACN/NOPB?

A: The primary differences are: (1) Slew Rate—LF444ACN/NOPB is 1V/µs versus TL064ACP at 3.5V/µs; (2) Input Bias Current—LF444ACN/NOPB is 10 pA versus TL064ACP at 30 pA; (3) Input Offset Voltage—LF444ACN/NOPB is 2 mV versus TL064ACP at 3 mV; (4) Supply Current—LF444ACN/NOPB is 600µA per channel versus TL064ACP at 200µA per channel; (5) Supply Voltage Range—LF444ACN/NOPB is fixed at 44V versus TL064ACP at 10V to 30V; (6) Product Status—LF444ACN/NOPB is Active versus TL064ACP is Obsolete; (7) RoHS Compliance—LF444ACN/NOPB is ROHS3 Compliant versus TL064ACP is non-compliant.

Q: Is the LF444ACN/NOPB suitable for applications requiring the TL064ACP's lower slew rate specification?

A: The LF444ACN/NOPB has a lower slew rate (1V/µs) than the TL064ACP (3.5V/µs). Applications requiring high-speed transient response or fast signal switching may not be compatible with the LF444ACN/NOPB. Verify circuit requirements before substitution.

Q: Are all substitute parts pin-compatible with the TL064ACP?

A: Yes. Both TL064ACN and LF444ACN/NOPB use the 14-DIP (0.300", 7.62mm) package with identical Through Hole mounting configuration. Pin assignments are compatible for direct socket replacement.

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

A: The LF444ACN/NOPB requires 600µA per channel (total 2.4mA for four channels) versus the TL064ACP at 200µA per channel (total 800µA for four channels). This represents a 3x increase in quiescent current draw. Power supply design and thermal management must accommodate this higher consumption.

Q: Can the LF444ACN/NOPB operate at the TL064ACP's minimum supply voltage of 10V?

A: No. The LF444ACN/NOPB supply voltage is specified at 44V fixed. It cannot operate at the TL064ACP's 10V minimum. Verify power supply design compatibility before substitution.

Q: Why is the LF444ACN/NOPB recommended despite performance differences?

A: The LF444ACN/NOPB is recommended for new designs because it is classified as Active (ensuring long-term availability) and ROHS3 Compliant (meeting modern regulatory requirements). The TL064ACP and TL064ACN are both obsolete. For legacy system maintenance requiring exact performance matching, use TL064ACN.
