Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL072CPWRG4 is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria are:

Mandatory Matching Parameters:

• Amplifier Type: J-FET input configuration
• Number of Circuits: 2 independent operational amplifiers
• Package / Case: 8-TSSOP surface mount form factor
• Voltage - Input Offset: 3 mV maximum
• Current - Supply: 1.4 mA per channel
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant

Allowable Parameter Variations:

• Slew Rate: Substitute parts may exceed the 13V/µs specification
• Gain Bandwidth Product: Substitute parts may differ from 5.25 MHz
• Current - Input Bias: Substitute parts may have lower input bias current
• Voltage - Supply Span: Substitute parts may support wider supply ranges
• Operating Temperature: Substitute parts may support extended temperature ranges
• Product Status: Active substitutes are preferred over obsolete parts

The TL072CPWR and TL082 series devices meet these criteria and are classified as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

TL072CPWR (Texas Instruments)

The TL072CPWR is the direct equivalent to the TL072CPWRG4, offering identical electrical specifications and package configuration. This substitute maintains the same slew rate (13V/µs), gain bandwidth product (5.25 MHz), input bias current (65 pA), and supply voltage range (10V to 30V). The TL072CPWR holds active product status, ensuring continued availability and manufacturing support. This part is the primary selection for direct replacement in existing designs.

TL082CPT (STMicroelectronics)

The TL082CPT is a functionally compatible substitute manufactured by STMicroelectronics. It maintains the same 8-TSSOP package, dual-circuit J-FET configuration, and core electrical parameters including 3 mV input offset voltage and 1.4 mA supply current. The TL082CPT offers enhanced performance characteristics: higher slew rate (16V/µs versus 13V/µs), lower input bias current (20 pA versus 65 pA), and extended supply voltage range (6V to 36V versus 10V to 30V). The device carries AEC-Q100 automotive qualification and active product status. Operating temperature range is 0°C to 70°C, matching the original specification.

TL082IPT (STMicroelectronics)

The TL082IPT is an extended-temperature variant of the TL082CPT, maintaining identical electrical specifications and package configuration. This substitute provides the same performance enhancements as the TL082CPT with an extended operating temperature range of -40°C to 105°C. The TL082IPT carries AEC-Q100 automotive qualification and active product status. Selection of this part is appropriate for applications requiring operation beyond the standard 0°C to 70°C range.

Frequently Asked Questions (FAQ)

Q: Can the TL072CPWR be used as a direct replacement for the TL072CPWRG4?

A: Yes. The TL072CPWR is electrically and mechanically identical to the TL072CPWRG4. Both devices feature the same slew rate (13V/µs), gain bandwidth product (5.25 MHz), input bias current (65 pA), input offset voltage (3 mV), supply current (1.4 mA per channel), supply voltage range (10V to 30V), and 8-TSSOP package. The primary difference is product status: TL072CPWR is active while TL072CPWRG4 is obsolete.

Q: What are the key differences between the TL072 and TL082 series?

A: The TL082 series offers enhanced performance specifications compared to the TL072 series. The TL082 provides higher slew rate (16V/µs versus 13V/µs), lower input bias current (20 pA versus 65 pA), and wider supply voltage range (6V to 36V versus 10V to 30V). Both series maintain identical input offset voltage (3 mV), supply current (1.4 mA), and 8-TSSOP package configuration. The TL082 series carries AEC-Q100 automotive qualification.

Q: Are the TL082CPT and TL082IPT interchangeable?

A: The TL082CPT and TL082IPT are electrically identical and share the same 8-TSSOP package. The primary difference is operating temperature range: TL082CPT operates from 0°C to 70°C, while TL082IPT operates from -40°C to 105°C. Selection between these parts depends on the required operating temperature specification for the application.

Q: What is the significance of the 8-TSSOP package specification?

A: The 8-TSSOP (Thin Shrink Small Outline Package) is a surface mount package with 0.173 inches (4.40 mm) width. All substitute parts maintain this identical package specification, ensuring mechanical compatibility with existing printed circuit board layouts and assembly processes. No PCB redesign is required when substituting between these parts.

Q: Can the TL082 series be used in applications originally designed for the TL072?

A: The TL082 series can be used in applications designed for the TL072 series when the enhanced performance characteristics are compatible with the circuit design. The TL082 provides superior slew rate and lower input bias current, which may improve circuit performance. However, circuit validation is necessary to confirm compatibility with specific application requirements.

Q: What does RoHS3 compliance indicate?

A: RoHS3 compliance indicates that the device meets the Restriction of Hazardous Substances Directive requirements, confirming the absence of restricted materials including lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers. All listed substitute parts maintain ROHS3 compliance.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: Moisture Sensitivity Level 1 (Unlimited) indicates that the device has unlimited shelf life and does not require special moisture control during storage or handling. No baking or desiccant storage is required prior to assembly.

Q: Are there packaging format differences between the substitute parts?

A: The TL072CPWRG4 and TL072CPWR are supplied in Cut Tape (CT) and Digi-Reel® packaging. The TL082CPT and TL082IPT are supplied in Tape & Reel (TR) packaging. Both packaging formats are standard for surface mount components and are compatible with automated assembly equipment. Packaging format selection depends on production volume and assembly process requirements.
