TL072CPWRE4 Equivalent & Substitute Parts

Part Overview

The TL072CPWRE4 is a J-FET input operational amplifier manufactured by Texas Instruments, configured as a dual-channel (2 circuit) device in an 8-TSSOP surface mount package. This part is classified as obsolete, with 695 units currently in stock. The TL072CPWRE4 is designed for applications requiring low input bias current and low input offset voltage characteristics typical of J-FET amplifier topologies.

Due to its obsolete product status, identifying equivalent and substitute parts is necessary for design continuity, long-term supply chain planning, and new production runs. Active alternatives with compatible electrical and mechanical specifications are available from both Texas Instruments and STMicroelectronics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL072CPWRE4 is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Amplifier Type: J-FET
• Number of Circuits: 2
• Package / Case: 8-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• Voltage - Input Offset: 3 mV
• Current - Supply: 1.4 mA (x2 Channels)

Secondary Compatibility Parameters:

• Slew Rate: 13 V/µs or higher
• Gain Bandwidth Product: 4 MHz or higher
• Current - Input Bias: 65 pA or lower
• Voltage - Supply Span (Min): 10 V or lower
• Voltage - Supply Span (Max): 30 V or higher
• Operating Temperature Range: Must encompass 0°C to 70°C minimum
• RoHS3 Compliance: Required
• MSL Rating: 1 (Unlimited)

The substitute parts TL072CPWR, TL082CPT, and TL082IPT meet these criteria with identical or superior electrical performance and identical mechanical packaging specifications.

Parameter Comparison

Engineering Selection Recommendations

TL072CPWR (Texas Instruments)

The TL072CPWR is the direct active equivalent to the TL072CPWRE4. Both parts share identical electrical specifications, including slew rate (13 V/µs), gain bandwidth product (5.25 MHz), input bias current (65 pA), and supply voltage range (10 V to 30 V). The TL072CPWR maintains active product status with 1615 units in inventory, providing superior supply chain continuity compared to the obsolete TL072CPWRE4. This part is recommended as the primary replacement for direct substitution in existing designs.

TL082CPT and TL082IPT (STMicroelectronics)

The TL082CPT and TL082IPT are functionally equivalent alternatives manufactured by STMicroelectronics. Both parts feature superior electrical performance in specific parameters: slew rate increased to 16 V/µs, input bias current reduced to 20 pA, and expanded supply voltage range (6 V to 36 V). Both TL082 variants carry AEC-Q100 automotive qualification and ROHS3 compliance. The TL082IPT extends the operating temperature range to -40°C to 105°C, providing broader environmental coverage. Selection between TL082CPT and TL082IPT depends on temperature range requirements for the application. Both parts maintain active status with substantial inventory availability (2200 and 5350 units respectively).

Selection Logic:

For applications requiring exact electrical parameter matching and Texas Instruments sourcing preference, select TL072CPWR. For applications benefiting from enhanced performance specifications, automotive qualification, or extended temperature range, select TL082CPT or TL082IPT based on operating temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can the TL072CPWR directly replace the TL072CPWRE4 without circuit modification?

A: Yes. The TL072CPWR is electrically and mechanically identical to the TL072CPWRE4. Both parts feature the same slew rate (13 V/µs), gain bandwidth product (5.25 MHz), input bias current (65 pA), voltage input offset (3 mV), supply current (1.4 mA per channel), and supply voltage range (10 V to 30 V). The 8-TSSOP package footprint is identical. No circuit modifications are required.

Q: What are the key differences between TL072CPWR and TL082CPT/TL082IPT?

A: The TL082 variants offer enhanced performance: slew rate increases from 13 V/µs to 16 V/µs, input bias current decreases from 65 pA to 20 pA, and supply voltage range expands from 10-30 V to 6-36 V. The TL082 parts carry AEC-Q100 automotive qualification. The TL082IPT additionally extends operating temperature from 0-70°C to -40-105°C. All three parts maintain identical 8-TSSOP packaging and 3 mV input offset voltage.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The TL072CPWR, TL082CPT, and TL082IPT are all ROHS3 compliant with MSL rating of 1 (Unlimited). All parts meet REACH requirements and carry EAR99 ECCN classification.

Q: Which substitute part should be selected for automotive applications?

A: The TL082CPT and TL082IPT are both AEC-Q100 qualified for automotive use. The TL082IPT is recommended for automotive applications requiring extended temperature range (-40°C to 105°C). The TL082CPT operates within the standard 0°C to 70°C range. The TL072CPWR does not carry automotive qualification.

Q: Is the 8-TSSOP package identical across all substitute parts?

A: Yes. All parts—TL072CPWRE4, TL072CPWR, TL082CPT, and TL082IPT—use the 8-TSSOP package with 0.173" width and 4.40 mm body width. PCB footprints and reflow profiles are identical.

Q: What is the inventory status for each substitute part?

A: TL072CPWR has 1615 units in stock. TL082CPT has 2200 units in stock. TL082IPT has 5350 units in stock. The original TL072CPWRE4 has 695 units remaining.
