TL062ACN Equivalent & Substitute Parts

Part Overview

The TL062ACN is a J-FET input operational amplifier featuring dual circuits in an 8-Mini DIP package, manufactured by STMicroelectronics. This device is classified as obsolete, though 1151 pieces remain available in stock. The TL062ACN operates across a supply voltage range of 6V to 36V with a slew rate of 3.5V/µs and 1 MHz gain bandwidth product, making it suitable for precision analog signal processing applications requiring low input bias current characteristics.

Due to its obsolete status, identifying equivalent and substitute parts is necessary for design continuity, long-term availability assurance, and potential performance optimization in new production runs or redesigns.

Substitute Part Grouping Explanation

Substitution of the TL062ACN is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria are:

Critical Parameters for Direct Substitution:

Amplifier Type: J-FET (required for input bias current performance)
Number of Circuits: 2 (functional requirement)
Package / Case: 8-DIP (0.300", 7.62mm) (mechanical compatibility)
Mounting Type: Through Hole (board assembly compatibility)

Secondary Parameters Defining Compatibility Bands:

Slew Rate: 3.5V/µs or higher
Gain Bandwidth Product: 1 MHz or higher
Current - Input Bias: 30 nA or lower
Voltage - Input Offset: 3 mV or lower
Voltage - Supply Span: minimum 6V to 36V maximum (or broader range)
Current - Output / Channel: 20 mA or higher

Substitute parts are grouped into two categories:

Upgrade Substitutes: Parts with identical base product number (TL062) but active product status and enhanced specifications.

Similar Substitutes: Parts with different base product numbers but compatible electrical and mechanical parameters. These include both J-FET amplifiers (preferred for direct functional replacement) and general-purpose amplifiers (acceptable where supply voltage and current requirements align).

Engineering Selection Recommendations

TL062IP (Upgrade Substitute - Recommended for Direct Replacement)

The TL062IP from Texas Instruments is the primary upgrade substitute for the obsolete TL062ACN. Both devices share the identical base product number (TL062) and J-FET amplifier architecture. The TL062IP maintains the same slew rate (3.5V/µs) and gain bandwidth product (1 MHz) as the original part. The TL062IP features superior input bias current performance (30 pA versus 30 nA) and is currently in active production status with 5325 pieces in stock. The primary design consideration is the reduced maximum supply voltage (30V versus 36V) and increased minimum supply voltage (10V versus 6V). The TL062IP is ROHS3 compliant and suitable for direct PCB substitution in through-hole 8-DIP applications.

LT1457CN8#PBF and LT1464CN8#PBF (J-FET Alternatives)

Both Analog Devices LT-series devices are J-FET amplifiers in 8-DIP packages with active product status. The LT1457CN8#PBF offers enhanced slew rate (4V/µs) and gain bandwidth product (1.7 MHz) with exceptional input bias current (7 pA) and input offset voltage (200 µV). The LT1464CN8#PBF provides ultra-low input bias current (0.5 pA) with 1 MHz gain bandwidth product and reduced supply current (145 µA per channel). Both devices operate across -40°C to 85°C and support supply voltages from 9V to 36V (LT1457) and 10V to 30V (LT1464). These parts are suitable where enhanced precision or extended temperature range is required.

OPA2137PA (J-FET Alternative)

The OPA2137PA from Texas Instruments is a J-FET MicroAmplifier with identical slew rate (3.5V/µs) and gain bandwidth product (1 MHz) to the TL062ACN. It features low input bias current (5 pA), low input offset voltage (1.5 mV), and higher output current capability (60 mA per channel). The OPA2137PA operates across -40°C to 85°C with supply voltage range of 4.5V to 36V. This device is suitable for applications requiring enhanced output drive capability while maintaining J-FET input characteristics.

LM358AN/NOPB and LM358AP (General-Purpose Alternatives)

The LM358 series devices are general-purpose amplifiers with 1 MHz gain bandwidth product (LM358AN/NOPB) or 700 kHz (LM358AP). These parts feature lower input bias current (45 nA and 15 nA respectively) and higher output current capability (40 mA per channel). The LM358AN/NOPB operates at 0°C to 70°C with 3V to 32V supply range, while the LM358AP operates at 0°C to 70°C with 3V to 30V supply range. These devices are suitable for cost-sensitive applications where J-FET input characteristics are not critical and lower supply voltage operation is acceptable.

All recommended substitutes are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the TL062IP directly replace the TL062ACN on existing PCBs?

A: Yes, the TL062IP is mechanically and functionally compatible with the TL062ACN. Both devices use the 8-DIP (0.300", 7.62mm) through-hole package. The primary design consideration is the supply voltage range: the TL062IP requires a minimum of 10V (versus 6V for the TL062ACN) and supports a maximum of 30V (versus 36V for the TL062ACN). Verify that your circuit's supply voltage falls within the 10V to 30V range before substitution.

Q: What is the difference between J-FET and general-purpose amplifiers in this comparison?

A: J-FET amplifiers feature extremely low input bias current (typically in the picoampere range) and are suitable for high-impedance signal sources and precision measurement applications. General-purpose amplifiers like the LM358 series have higher input bias current (in the nanoampere range) but offer lower cost and broader supply voltage compatibility. Select J-FET devices when input bias current performance is critical; select general-purpose devices for cost-sensitive applications with lower impedance sources.

Q: Are all substitute parts available in the same packaging?

A: Yes, all substitute parts listed in this document are available in the 8-DIP (0.300", 7.62mm) through-hole package, ensuring mechanical compatibility with existing PCB designs. Verify the supplier device package designation (8-PDIP or 8-Mini DIP) when ordering to ensure correct lead spacing and pin configuration.

Q: What are the key electrical differences between the TL062ACN and LT1464CN8#PBF?

A: The LT1464CN8#PBF offers superior input bias current performance (0.5 pA versus 30 nA), lower input offset voltage (600 µV versus 3 mV), and reduced supply current (145 µA per channel versus 200 µA). However, the LT1464CN8#PBF has a lower slew rate (0.9V/µs versus 3.5V/µs) and narrower supply voltage range (10V to 30V versus 6V to 36V). Select the LT1464CN8#PBF for precision, low-power applications; select the TL062IP for applications requiring higher slew rate or extended supply voltage range.

Q: Can I use an LM358 series device as a substitute for the TL062ACN?

A: The LM358 series devices are functionally compatible in terms of dual-circuit configuration and 8-DIP packaging. However, they are general-purpose amplifiers rather than J-FET amplifiers, resulting in higher input bias current (15 to 45 nA versus 30 nA) and lower slew rate (0.3V/µs versus 3.5V/µs). Use LM358 devices only in applications where J-FET input characteristics are not required and where the lower slew rate is acceptable.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts listed are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components in the European Union and other regulated markets.

Q: Which substitute offers the best overall performance improvement over the TL062ACN?

A: The LT1457CN8#PBF provides the most comprehensive performance enhancement, featuring higher slew rate (4V/µs), higher gain bandwidth product (1.7 MHz), and exceptional input bias current (7 pA). However, this device has higher supply current consumption (1.8 mA per channel) and narrower supply voltage range (9V to 36V). Select based on your specific application requirements: prioritize slew rate and bandwidth for high-speed applications, or prioritize input bias current for precision measurement applications.
