TL072BIN Equivalent & Substitute Parts

Part Overview

The TL072BIN is a J-FET input operational amplifier manufactured by STMicroelectronics, configured as a dual-channel (2 circuit) device in an 8-Mini DIP through-hole package. This part is classified as obsolete, though 1,330 units remain in current inventory as new original stock. The TL072BIN is qualified to AEC-Q100 automotive standards and operates across an extended temperature range of -40°C to 105°C, making it suitable for demanding automotive and industrial applications requiring low input bias current and stable gain-bandwidth characteristics.

Due to its obsolete product status, locating equivalent or substitute components is necessary for ongoing production support, design continuity, and long-term supply chain management. Active alternatives exist from both Texas Instruments and Analog Devices that maintain functional compatibility within specified electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the TL072BIN is determined by strict alignment across the following critical parameters:

Mandatory Compatibility Criteria:

Amplifier Type: J-FET input configuration
Number of Circuits: Dual-channel (2 circuits)
Package / Case: 8-DIP (0.300", 7.62mm) form factor
Mounting Type: Through-hole technology
RoHS Status: ROHS3 Compliant

Performance Parameter Ranges: Substitute parts must operate within the electrical envelope defined by the TL072BIN specifications. Key performance metrics include slew rate (16 V/µs), gain bandwidth product (4 MHz), input bias current (20 pA), input offset voltage (1 mV), supply current (1.4 mA), and output current per channel (40 mA). Substitute devices may exceed these specifications without functional degradation, provided they remain within the specified supply voltage range (6 V to 36 V minimum and maximum).

Operating Temperature Consideration: The TL072BIN operates from -40°C to 105°C. Substitute parts with narrower temperature ranges (such as 0°C to 70°C) are acceptable for applications that do not require the full extended temperature capability, but are not suitable for designs requiring the full automotive temperature specification.

Compliance and Certification: All substitute parts listed maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component.

Engineering Selection Recommendations

Primary Substitutes (Texas Instruments TL072 Series):

The TL072IP, TL072CP, TL072BCP, and TL072ACP are all active products from Texas Instruments sharing the TL072 base product number. These devices maintain identical supply current (1.4 mA), slew rate (13 V/µs), and gain bandwidth product (5.25 MHz) specifications. All are packaged in 8-DIP through-hole format with ROHS3 compliance.

The TL072IP offers the widest operating temperature range (-40°C to 85°C) among the Texas Instruments variants, making it the most suitable direct replacement for applications requiring extended temperature operation. The TL072CP and TL072BCP are restricted to 0°C to 70°C operation and are appropriate for commercial and industrial applications not requiring automotive temperature specifications. The TL072ACP operates identically to TL072CP and TL072BCP within the 0°C to 70°C range.

Secondary Substitute (Analog Devices LT1169CN8#PBF):

The LT1169CN8#PBF from Analog Devices provides an alternative J-FET dual-channel operational amplifier in 8-DIP packaging. This device exhibits superior input bias current (4 pA versus 20 pA) and input offset voltage (0.6 mV versus 1 mV), indicating enhanced DC precision characteristics. However, the LT1169CN8#PBF operates at higher supply current (5.3 mA versus 1.4 mA) and exhibits lower slew rate (4.2 V/µs versus 16 V/µs). The maximum supply voltage rating is 40 V, exceeding the TL072BIN specification of 36 V. Operating temperature range is limited to 0°C to 70°C. This substitute is suitable for precision analog applications where input offset and bias current performance are critical, provided power consumption and slew rate limitations are acceptable.

Compliance and Availability:

All substitute parts maintain ROHS3 compliance and REACH unaffected status. Texas Instruments variants demonstrate significantly higher inventory availability (81,250 units for TL072CP, 4,875 units for TL072IP, 2,356 units for TL072ACP, and 1,664 units for TL072BCP) compared to the obsolete TL072BIN (1,330 units). The LT1169CN8#PBF maintains 938 units in stock.

Frequently Asked Questions (FAQ)

Q: Can the TL072IP directly replace the TL072BIN in automotive applications?

A: The TL072IP is electrically compatible and maintains the 8-DIP through-hole package format. However, the TL072IP operates from -40°C to 85°C, while the TL072BIN extends to 105°C. For applications requiring operation above 85°C, the TL072IP is not suitable. Additionally, the TL072IP is not qualified to AEC-Q100 automotive standards; verification of application requirements is necessary.

Q: What is the primary difference between TL072CP, TL072BCP, and TL072ACP?

A: These three Texas Instruments variants are functionally equivalent in electrical performance (slew rate 13 V/µs, gain bandwidth product 5.25 MHz, supply current 1.4 mA). The primary differences are input offset voltage specifications (TL072BCP: 2 mV, TL072CP and TL072ACP: 3 mV) and operating temperature range (all three: 0°C to 70°C). Selection between these variants depends on DC accuracy requirements and application temperature constraints.

Q: Is the LT1169CN8#PBF suitable for high-speed signal processing applications?

A: The LT1169CN8#PBF exhibits a slew rate of 4.2 V/µs, which is significantly lower than the TL072BIN (16 V/µs) and Texas Instruments TL072 variants (13 V/µs). For applications requiring rapid signal transitions or high-frequency transient response, the LT1169CN8#PBF is not recommended. This device is optimized for precision DC and low-frequency analog signal conditioning.

Q: Can I use a substitute part with a narrower operating temperature range in a design originally specified for -40°C to 105°C?

A: Substitution with a narrower temperature range is only acceptable if the actual application operating environment does not exceed the substitute part's specified limits. The TL072CP, TL072BCP, and TL072ACP are limited to 0°C to 70°C operation. If your application requires operation below 0°C or above 70°C, these variants are not suitable. The TL072IP extends to -40°C to 85°C, providing broader coverage but still not reaching the original 105°C maximum.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (TL072IP, TL072CP, TL072BCP, TL072ACP, and LT1169CN8#PBF) are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment with the original TL072BIN component.

Q: What is the impact of higher supply current in the LT1169CN8#PBF?

A: The LT1169CN8#PBF operates at 5.3 mA supply current compared to 1.4 mA for the TL072BIN and Texas Instruments variants. This represents approximately 3.8 times higher power consumption. In battery-powered or power-constrained applications, this increased current draw may necessitate design modifications to power supply and thermal management. Evaluation of power budget impact is required before substitution.

Q: Can I substitute the TL072BIN with multiple different variants within the same design?

A: All Texas Instruments TL072 variants (TL072IP, TL072CP, TL072BCP, TL072ACP) share identical pinout and 8-DIP package format, enabling functional interchangeability within a single PCB design. However, differences in operating temperature range, input offset voltage, and supply current specifications must be evaluated for each application circuit. Mixed usage of variants with different temperature ratings or precision specifications within a single system may introduce performance inconsistencies and is not recommended without explicit circuit-level analysis.
