TL074ACN Equivalent & Substitute Parts

Part Overview

The TL074ACN is a J-FET input operational amplifier featuring four independent circuits in a 14-DIP through-hole package, manufactured by STMicroelectronics. This device is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and procurement. The TL074ACN operates across a 36V supply span with a slew rate of 13V/µs and gain bandwidth product of 3 MHz, making it suitable for precision analog signal processing applications requiring low input bias current characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL074ACN is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Amplifier type (J-FET input architecture)
• Number of circuits (4 independent operational amplifiers)
• Supply voltage span (minimum and maximum operating voltages)
• Slew rate and gain bandwidth product (frequency response characteristics)
• Input bias current and input offset voltage (precision specifications)
• Output current capability per channel
• Operating temperature range

Mechanical Compatibility Criteria:

• Package type (14-DIP through-hole configuration)
• Physical dimensions (0.300", 7.62mm pitch)
• Pin count and pinout arrangement

Substitute parts are grouped into two categories: direct equivalents (identical electrical and mechanical specifications) and functional alternatives (compatible electrical performance within application tolerance but with differing secondary parameters such as product status or supply current).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred for Pin-Compatible Replacement):

TL074BCN (STMicroelectronics) serves as the direct electrical and mechanical equivalent to TL074ACN. Both devices share identical slew rate (13V/µs), gain bandwidth product (3 MHz), supply current (1.4mA per channel), output current capability (40 mA per channel), and voltage supply span (36V). The primary distinction is input offset voltage specification (1 mV for TL074BCN versus 3 mV for TL074ACN), representing improved precision in the substitute. Both are classified as obsolete products.

Active Product Alternatives:

TL074IN (Texas Instruments) is an active product offering enhanced gain bandwidth product (5.25 MHz) and extended operating temperature range (-40°C to 85°C). However, this device exhibits higher input bias current (65 pA versus 20 pA) and reduced supply voltage span (10V to 30V versus 36V). This substitute is suitable for applications where extended temperature operation and higher frequency response are required, provided the reduced supply voltage range is compatible with the circuit design.

LF444CN/NOPB and LF444ACN/NOPB (Texas Instruments) are active J-FET quad operational amplifiers with significantly reduced supply current (0.6 mA per channel versus 1.4 mA) and lower output current capability (14 mA per channel versus 40 mA). These devices feature reduced slew rate (1 V/µs versus 13 V/µs) and gain bandwidth product (1 MHz versus 3 MHz). These substitutes are applicable only in low-speed, low-power applications where the reduced performance specifications are acceptable.

All substitute candidates maintain ROHS3 compliance and through-hole 14-DIP packaging compatibility with the original TL074ACN.

Frequently Asked Questions (FAQ)

Q: Can TL074IN be used as a direct replacement for TL074ACN in all applications?

A: TL074IN is mechanically compatible and shares the same 14-DIP package. However, electrical differences exist: TL074IN operates across a 10V to 30V supply span compared to TL074ACN's 36V span, and exhibits higher input bias current (65 pA versus 20 pA). TL074IN is suitable only for applications where the reduced supply voltage range and higher input bias current are acceptable. TL074IN is an active product, whereas TL074ACN is obsolete.

Q: What is the primary advantage of LF444CN/NOPB over TL074ACN?

A: LF444CN/NOPB is an active product with significantly lower supply current consumption (0.6 mA per channel versus 1.4 mA). This device is suitable for battery-powered or power-constrained applications. However, LF444CN/NOPB exhibits substantially reduced slew rate (1 V/µs versus 13 V/µs) and gain bandwidth product (1 MHz versus 3 MHz), limiting its use to low-frequency signal processing applications.

Q: Are all substitute parts available in the same 14-DIP through-hole package?

A: All substitute parts listed are available in 14-DIP through-hole packages with identical 0.300" (7.62mm) pitch. Physical board layout compatibility is maintained across all substitutes.

Q: Which substitute offers the best performance match to TL074ACN?

A: TL074BCN provides the closest electrical performance match, with identical slew rate (13 V/µs), gain bandwidth product (3 MHz), supply current (1.4 mA per channel), and output current capability (40 mA per channel). TL074BCN is classified as obsolete, similar to TL074ACN.

Q: What is the supply voltage compatibility range for each substitute?

A: TL074ACN and TL074BCN operate across a 36V supply span. TL074IN operates across a 10V to 30V span (reduced range). LF444CN/NOPB operates across a 36V span. LF444ACN/NOPB operates across a 44V span (expanded range). Circuit designs must verify that the selected substitute's supply voltage range accommodates the intended power supply configuration.

Q: Can LF444ACN/NOPB be used in place of TL074ACN?

A: LF444ACN/NOPB is mechanically compatible (14-DIP package) and operates across an expanded 44V supply span. However, it exhibits significantly reduced slew rate (1 V/µs versus 13 V/µs), lower gain bandwidth product (1 MHz versus 3 MHz), and reduced output current capability (14 mA per channel versus 40 mA). LF444ACN/NOPB is suitable only for low-frequency, low-power applications where these reduced specifications are acceptable.

Q: What is the input bias current difference between TL074ACN and its substitutes?

A: TL074ACN specifies 20 pA input bias current. TL074BCN matches this specification. TL074IN exhibits higher input bias current (65 pA). LF444CN/NOPB and LF444ACN/NOPB feature lower input bias current (10 pA). Applications requiring ultra-low input bias current should prioritize LF444 series devices.

Q: Are all substitutes RoHS3 compliant?

A: All substitute parts listed (TL074BCN, TL074IN, LF444CN/NOPB, and LF444ACN/NOPB) are ROHS3 compliant, matching the compliance status of the original TL074ACN.
