TL072CPSRE4 Equivalent & Substitute Parts

Part Overview

The TL072CPSRE4 is a J-FET input operational amplifier manufactured by Texas Instruments, configured as a dual-channel (2 circuit) device in an 8-SOIC surface mount package. This component is designed for applications requiring low input bias current and high input impedance characteristics typical of J-FET amplifier architectures.

The TL072CPSRE4 has been discontinued at DiGi Electronics. Equivalent substitute parts are available to maintain design continuity and ensure component availability for production and repair applications. Substitution must be evaluated based on electrical performance parameters, package compatibility, and operating specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL072CPSRE4 is determined by the following critical parameters:

Primary Substitution Criteria:

• Amplifier Type: J-FET input architecture
• Number of Circuits: Dual-channel (2 circuit) configuration
• Package Compatibility: 8-SOIC surface mount form factor
• Electrical Performance: Slew rate, gain bandwidth product, input bias current, and supply voltage range

Substitution Logic:

The TL072CPSR represents a direct manufacturer-recommended substitute. This part maintains identical electrical specifications (13 V/µs slew rate, 3 MHz gain bandwidth product, 65 pA input bias current) and package configuration. The primary difference is packaging format (Cut Tape & Digi-Reel versus tape reel configuration) and product status (Last Time Buy versus Discontinued).

The MC33172D and MC33172DT are cross-manufacturer alternatives from STMicroelectronics. These parts differ in amplifier type classification (General Purpose versus J-FET) and exhibit different electrical characteristics. Substitution with MC33172 series requires verification that the application tolerates reduced slew rate (2 V/µs versus 13 V/µs), lower gain bandwidth product (2.1 MHz versus 3 MHz), and higher input bias current (20 nA versus 65 pA). The MC33172 series offers extended operating temperature range (-40°C to 105°C) and wider supply voltage span (4 V to 44 V).

Parameter Comparison

Engineering Selection Recommendations

TL072CPSR (Recommended Primary Substitute):

The TL072CPSR is the manufacturer-recommended substitute for the TL072CPSRE4. This part maintains complete electrical and mechanical compatibility with identical specifications across all critical parameters. Both parts are ROHS3 compliant and carry MSL Level 1 rating. The TL072CPSR is currently in active production status with higher inventory availability (5249 units) compared to the discontinued TL072CPSRE4. Selection of TL072CPSR requires no circuit redesign or performance re-evaluation.

MC33172D / MC33172DT (Alternative Substitutes):

The MC33172 series from STMicroelectronics represents a functional alternative when J-FET input characteristics are not mandatory for the application. These parts are currently in active production status with substantial inventory availability (100400 units for MC33172D, 45300 units for MC33172DT). Both variants are ROHS3 compliant with MSL Level 1 rating.

Substitution with MC33172 series introduces the following electrical trade-offs:

• Reduced slew rate: 2 V/µs (versus 13 V/µs)
• Reduced gain bandwidth product: 2.1 MHz (versus 3 MHz)
• Increased input bias current: 20 nA (versus 65 pA)
• Improved input offset voltage: 1 mV (versus 3 mV)
• Reduced supply current: 220 µA (versus 1.4 mA per channel)

The MC33172 series accommodates extended operating temperature range (-40°C to 105°C) and wider supply voltage span (4 V to 44 V), providing operational flexibility beyond the TL072 specification envelope.

Packaging Consideration:

The MC33172 series utilizes a narrower 8-SOIC package (0.154", 3.90mm width) compared to the TL072 series (0.209", 5.30mm width). PCB layout modification is required for MC33172 substitution.

Frequently Asked Questions (FAQ)

Q: Can TL072CPSR be used as a direct replacement for TL072CPSRE4?

A: Yes. The TL072CPSR is the manufacturer-recommended substitute with identical electrical specifications, package configuration, and compliance certifications. No circuit modification is required.

Q: What are the key differences between TL072CPSRE4 and MC33172D?

A: The primary differences are amplifier type (J-FET versus General Purpose), slew rate (13 V/µs versus 2 V/µs), gain bandwidth product (3 MHz versus 2.1 MHz), input bias current (65 pA versus 20 nA), and package width (5.30mm versus 3.90mm). Applications requiring high-speed transient response or extremely low input bias current should retain the TL072 architecture.

Q: Is the MC33172 series suitable for audio frequency applications?

A: The MC33172 series supports audio frequency operation within its 2.1 MHz gain bandwidth product specification. Applications requiring bandwidth beyond 2.1 MHz or slew rates exceeding 2 V/µs should use the TL072 series.

Q: What is the difference between MC33172D and MC33172DT?

A: Both parts are electrically identical. The primary difference is packaging format: MC33172D is supplied in Tube packaging, while MC33172DT is supplied in Cut Tape & Digi-Reel format. Selection depends on production volume and handling requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The TL072CPSR, MC33172D, and MC33172DT are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: Can MC33172 be used in applications originally designed for TL072?

A: Substitution requires circuit performance evaluation. The reduced slew rate and gain bandwidth product may impact high-frequency performance. The extended operating temperature range and wider supply voltage span of MC33172 may provide advantages in certain applications. Application-specific testing is necessary to confirm functional equivalence.

Q: What is the current availability status of each substitute?

A: TL072CPSRE4 is discontinued. TL072CPSR is Last Time Buy status. MC33172D and MC33172DT are in active production with substantial inventory (100400 and 45300 units respectively).
