TL072CPE4 Equivalent & Substitute Parts

Part Overview

The TL072CPE4 is a J-FET input operational amplifier featuring two independent circuits in an 8-DIP package. This device is classified as obsolete, though 1012 units remain in stock. The TL072CPE4 is designed for applications requiring low input bias current and low input offset voltage characteristics typical of J-FET amplifier designs. Due to its obsolete status, identifying equivalent and substitute parts is essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL072CPE4 is determined by the following critical parameters:

Primary Substitution Criteria:

• Package compatibility: 8-DIP (0.300", 7.62 mm) through-hole mounting
• Number of circuits: 2 independent amplifier circuits
• Amplifier type: J-FET input stage
• Electrical performance envelope: Slew rate, gain bandwidth product, input bias current, and input offset voltage

Substitution Logic:

The TL072CP represents a direct manufacturer equivalent from Texas Instruments. It maintains identical electrical specifications and package configuration while offering active product status and higher inventory availability (81,250 units). The packaging format differs (Tube vs. unspecified for the main part), but the electrical and mechanical compatibility is complete.

The MUSES8820D represents a functional alternative from Nisshinbo Micro Devices Inc. While it maintains the 8-DIP package and dual-circuit configuration, it employs an audio amplifier topology rather than J-FET input architecture. This substitute exhibits different electrical characteristics: higher gain bandwidth product (11 MHz vs. 5.25 MHz), higher input bias current (100 nA vs. 65 pA), and lower slew rate (5 V/µs vs. 13 V/µs). The MUSES8820D operates across an extended temperature range (-40°C to 85°C) and supports higher output current per channel (50 mA).

Engineering Selection Recommendations

TL072CP Selection:

The TL072CP is the primary recommended substitute for the obsolete TL072CPE4. This part maintains complete electrical and mechanical compatibility with identical specifications across all critical parameters. The TL072CP carries active product status, ensuring long-term availability and supply chain stability. Both parts are ROHS3 compliant and carry identical REACH and ECCN classifications. The primary advantage of TL072CP is the significantly higher inventory availability (81,250 units in stock versus 1,012 units for the main part), reducing procurement risk for production applications.

MUSES8820D Selection:

The MUSES8820D is suitable only for applications where the electrical performance differences are acceptable. This substitute is appropriate for designs that can tolerate higher input bias current (100 nA vs. 65 pA), lower slew rate (5 V/µs vs. 13 V/µs), and higher supply current consumption (8 mA vs. 1.4 mA). The MUSES8820D offers advantages in extended operating temperature range (-40°C to 85°C) and higher output current capability (50 mA per channel). This part is RoHS compliant and maintains the same package footprint. Selection of MUSES8820D requires circuit-level verification that the audio amplifier topology and altered electrical characteristics do not degrade system performance.

Frequently Asked Questions (FAQ)

Q: Can TL072CP be used as a direct replacement for TL072CPE4 without circuit modification?

A: Yes. The TL072CP maintains identical electrical specifications, package configuration, and pin assignment. No circuit modification is required for direct substitution.

Q: What are the key differences between TL072CPE4 and MUSES8820D?

A: The primary differences are amplifier topology (J-FET vs. Audio), input bias current (65 pA vs. 100 nA), slew rate (13 V/µs vs. 5 V/µs), and supply current (1.4 mA vs. 8 mA). The MUSES8820D offers extended temperature range and higher output current per channel.

Q: Is the 8-DIP package identical between all three parts?

A: Yes. All three parts use the 8-DIP (0.300", 7.62 mm) through-hole package with identical pin spacing and mounting requirements.

Q: Why is TL072CPE4 classified as obsolete?

A: Product status reflects manufacturer discontinuation decisions. The TL072CP remains in active production as the current equivalent.

Q: Are there compliance differences between the substitutes?

A: Both TL072CP and TL072CPE4 are ROHS3 compliant. MUSES8820D is RoHS compliant. All three parts are REACH unaffected and carry EAR99 ECCN classification.

Q: What is the impact of higher input bias current in MUSES8820D?

A: Higher input bias current (100 nA vs. 65 pA) may affect circuit performance in high-impedance input applications. Circuit-level analysis is required to determine acceptability.

Q: Can MUSES8820D operate at the same supply voltages as TL072CPE4?

A: MUSES8820D supports a wider supply voltage range (7 V to 32 V vs. 10 V to 30 V). It is compatible with TL072CPE4 supply voltages and extends to lower minimum voltage.
