TL072IN Equivalent & Substitute Parts

Part Overview

The TL072IN is a J-FET input operational amplifier manufactured by STMicroelectronics, configured as a dual-channel (2 circuit) device in an 8-Mini DIP package. This component is classified as obsolete, though 3,130 units remain in stock as new original inventory. The TL072IN is qualified to AEC-Q100 automotive standards and operates across a supply voltage range of 6V to 36V with an operating temperature range of -40°C to 105°C.

Due to its obsolete product status, equivalent and substitute parts are necessary for new designs, long-term availability assurance, and applications requiring active product support. Substitute parts listed below maintain functional compatibility through matching or superior electrical characteristics while offering active product status from major manufacturers.

Engineering Selection Recommendations

For Direct Replacement (J-FET Topology Required):

The AD712JNZ and AD712KNZ from Analog Devices provide the closest functional equivalence to the TL072IN. Both maintain J-FET input architecture, dual-channel configuration, 4 MHz gain bandwidth product, and 8-DIP packaging. The AD712 series offers superior slew rate (20 V/µs versus 16 V/µs) and lower input offset voltage (0.3 mV versus 3 mV). Both parts are ROHS3 compliant and carry active product status with substantial inventory availability (2,001 and 3,745 units respectively). The minimum supply voltage requirement increases from 6V to 9V; applications operating below 9V require alternative selection.

The LF412CN/NOPB from Texas Instruments provides equivalent J-FET performance with 4 MHz bandwidth and maintains the lowest input offset voltage (1 mV) among J-FET substitutes. This part supports supply voltages up to 40V (versus 36V maximum for TL072IN) and offers the highest inventory availability (44,180 units). Operating temperature range is limited to 0°C to 70°C, restricting use in the full automotive temperature range of the original part.

The LF353N/NOPB from Texas Instruments offers J-FET input characteristics with 4 MHz bandwidth and 13 V/µs slew rate, meeting minimum substitution criteria. This part maintains 10V to 36V supply range and is ROHS3 compliant with active product status.

For Enhanced Performance Applications:

The LM4562NA/NOPB and LME49720NA/NOPB from Texas Instruments provide superior performance characteristics including 55 MHz gain bandwidth product, 20 V/µs slew rate, and exceptionally low input bias current (10 nA). These audio-grade amplifiers support extended temperature range (-40°C to 85°C) and are suitable for applications requiring higher bandwidth and lower noise. Supply voltage range is 5V to 34V. Both parts are ROHS3 compliant with active product status and substantial inventory (8,125 and 8,769 units respectively).

For Cost-Optimized Applications (Where J-FET Input Not Required):

The NE5532AP from Texas Instruments provides general purpose amplification with 10 MHz gain bandwidth product and 9 V/µs slew rate. This part is ROHS3 compliant and active, with 3,497 units in stock. Supply range is limited to 10V to 30V, and input bias current is significantly higher (200 nA).

Compliance and Certification:

All recommended substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited). The LM4562NA/NOPB and LME49720NA/NOPB support the extended automotive temperature range (-40°C to 85°C) closest to the original TL072IN specification (-40°C to 105°C). Applications requiring full AEC-Q100 automotive qualification should verify specific part certifications with manufacturers, as this data is not provided for substitute parts.

Frequently Asked Questions (FAQ)

Q: Can the AD712JNZ directly replace the TL072IN in all applications?

A: The AD712JNZ provides functional equivalence for most applications due to matching J-FET topology, dual-channel configuration, 4 MHz bandwidth, and 8-DIP packaging. However, the minimum supply voltage increases from 6V to 9V. Applications operating at 6V to 8V supply voltage require alternative selection. Operating temperature range is reduced from -40°C to 105°C to 0°C to 70°C, limiting use in extended automotive temperature environments.

Q: What is the primary difference between J-FET and general purpose amplifier substitutes?

A: J-FET input amplifiers (AD712JNZ, AD712KNZ, LF353N/NOPB, LF412CN/NOPB) feature extremely low input bias current (20-50 pA) and high input impedance, suitable for high-impedance signal sources and precision measurement applications. General purpose amplifiers (AD706JNZ, MC1458P, NE5532AP) have higher input bias current (50 nA to 200 nA) and lower input impedance, appropriate for standard signal conditioning and audio applications. Selection depends on circuit requirements for input impedance and bias current characteristics.

Q: Is the LF412CN/NOPB suitable for automotive applications requiring AEC-Q100 qualification?

A: The LF412CN/NOPB is ROHS3 compliant and maintains J-FET performance equivalent to the TL072IN. However, the provided data does not confirm AEC-Q100 qualification for this part. Applications requiring automotive qualification should verify certification status directly with Texas Instruments before design implementation.

Q: Why do some substitute parts have higher supply current requirements?

A: Supply current varies based on amplifier architecture and performance class. The TL072IN draws 1.4 mA total supply current, while the AD712 series draws 5 mA and the LM4562 series draws 10 mA per channel. Higher supply current typically correlates with higher bandwidth, lower noise, and improved slew rate performance. Applications with strict power budget constraints should prioritize lower-current alternatives such as LF353N/NOPB (3.6 mA for dual channels) or LF412CN/NOPB (3.6 mA for dual channels).

Q: Can the LM4562NA/NOPB be used in place of the TL072IN for audio applications?

A: The LM4562NA/NOPB is specifically designed for audio applications and provides superior performance: 55 MHz bandwidth versus 4 MHz, 20 V/µs slew rate versus 16 V/µs, and exceptionally low input bias current (10 nA). This part is suitable for audio signal processing where the TL072IN would be used. However, the supply voltage range is 5V to 34V (versus 6V to 36V), and operating temperature is -40°C to 85°C. Verify supply voltage compatibility before implementation.

Q: What packaging considerations apply to these substitute parts?

A: All listed substitute parts maintain the 8-DIP (0.300", 7.62mm) through-hole package format, ensuring mechanical compatibility with existing PCB layouts designed for the TL072IN. All parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), requiring no special handling or storage conditions beyond standard component practices.

Q: Which substitute part offers the best balance of performance and availability?

A: The LF412CN/NOPB from Texas Instruments provides optimal balance: J-FET input topology matching the TL072IN, 4 MHz bandwidth, 15 V/µs slew rate, lowest input offset voltage among J-FET substitutes (1 mV), extended supply range to 40V, active product status, and highest inventory availability (44,180 units). The primary limitation is operating temperature range (0°C to 70°C), which restricts use in full automotive temperature environments.

Q: Are there supply voltage compatibility issues when substituting the TL072IN?

A: Yes. The TL072IN operates from 6V minimum supply voltage. Most J-FET substitutes (AD712 series, LF353N/NOPB, LF412CN/NOPB) require minimum 9V to 10V supply voltage. Applications operating at 6V to 8V supply voltage cannot use these substitutes. The AD706JNZ general purpose amplifier supports 4V minimum supply, but lacks J-FET input characteristics. Verify supply voltage requirements before part selection.
