TL072ACPSR Equivalent & Substitute Parts Reference

Part Overview

The TL072ACPSR 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 classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The TL072ACPSR operates across a 10V to 30V supply voltage range with a slew rate of 13V/µs and 3 MHz gain bandwidth product, making it suitable for precision analog signal processing applications requiring low input bias current characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL072ACPSR is determined by the following critical parameters: dual-channel configuration (2 circuits), surface mount packaging in 8-SOIC form factor, supply voltage compatibility (minimum 10V, maximum 30V), and functional amplifier classification. The substitute parts identified fall into two categories based on amplifier type alignment:

Category 1 - Direct J-FET Type Match: TL072CPSR maintains identical J-FET amplifier architecture, matching slew rate (13V/µs), gain bandwidth product (3 MHz), input bias current (65 pA), and input offset voltage (3 mV). This part differs only in product status (Last Time Buy versus Obsolete) and packaging format (Cut Tape & Digi-Reel versus standard packaging).

Category 2 - General Purpose Amplifier Alternatives: MC33172D and MC33172DT are general purpose amplifiers with dual-channel configuration and 8-SOIC packaging. These parts operate within the TL072ACPSR supply voltage range (4V to 44V encompasses the 10V to 30V requirement) and maintain surface mount compatibility. However, these alternatives exhibit different electrical characteristics: lower slew rate (2V/µs versus 13V/µs), reduced gain bandwidth product (2.1 MHz versus 3 MHz), higher input bias current (20 nA versus 65 pA), and lower input offset voltage (1 mV versus 3 mV).

Engineering Selection Recommendations

Primary Recommendation: TL072CPSR

The TL072CPSR is the preferred substitute for the obsolete TL072ACPSR. This part maintains identical electrical specifications across all critical parameters: J-FET amplifier type, dual-channel configuration, 13V/µs slew rate, 3 MHz gain bandwidth product, 65 pA input bias current, and 3 mV input offset voltage. Both parts operate within the 10V to 30V supply voltage range and are housed in 8-SOIC surface mount packages. The TL072CPSR carries active Last Time Buy status with significantly higher inventory availability (5249 units versus 676 units), ensuring procurement continuity. Both parts maintain ROHS3 compliance and MSL Level 1 rating.

Secondary Recommendation: MC33172D or MC33172DT

The MC33172 series (both D and DT variants) provides functional substitution when J-FET input characteristics are not critical to circuit performance. These general purpose amplifiers maintain dual-channel configuration and 8-SOIC surface mount packaging with active product status and superior inventory levels (100400 and 45300 units respectively). The MC33172 series operates across a wider supply voltage range (4V to 44V) and extended operating temperature range (-40°C to 105°C). However, these alternatives exhibit reduced slew rate (2V/µs), lower gain bandwidth product (2.1 MHz), and significantly higher input bias current (20 nA). The MC33172 series is suitable for applications where high-speed signal processing and ultra-low input bias current are not required.

Package Consideration:

The MC33172 series uses a narrower 8-SOIC package (0.154", 3.90mm width) compared to the TL072 series (0.209", 5.30mm width). PCB layout modifications may be required for direct physical substitution.

Frequently Asked Questions (FAQ)

Q1: Can TL072CPSR directly replace TL072ACPSR in existing designs?

Yes. The TL072CPSR is electrically and functionally identical to the TL072ACPSR across all specified parameters. Both parts are J-FET input dual-channel operational amplifiers with identical slew rate, gain bandwidth product, input bias current, input offset voltage, and supply voltage specifications. The primary difference is product status: TL072ACPSR is obsolete while TL072CPSR is Last Time Buy. Physical packaging is identical (8-SOIC, 0.209", 5.30mm width), permitting direct PCB substitution without layout modifications.

Q2: What are the key differences between TL072ACPSR and MC33172 series?

The primary differences are amplifier type classification and electrical performance characteristics. TL072ACPSR uses J-FET input architecture with 13V/µs slew rate and 65 pA input bias current. MC33172 series uses general purpose amplifier architecture with 2V/µs slew rate and 20 nA input bias current. The MC33172 series operates across a wider supply voltage range (4V to 44V versus 10V to 30V) and extended temperature range (-40°C to 105°C versus 0°C to 70°C). The MC33172 series is suitable for applications where high-speed transient response and ultra-low input bias current are not required.

Q3: Are there package compatibility issues when substituting MC33172 for TL072ACPSR?

Yes. The MC33172 series uses a narrower 8-SOIC package (0.154", 3.90mm width) compared to the TL072ACPSR (0.209", 5.30mm width). While both are 8-pin SOIC packages, the physical dimensions differ. Direct PCB substitution without layout modification is not possible. PCB redesign or adapter solutions are required for physical compatibility.

Q4: Which substitute part has the best inventory availability?

MC33172D has the highest inventory availability at 100400 units in stock. MC33172DT follows with 45300 units. TL072CPSR has 5249 units available. The TL072ACPSR (original part) has 676 units remaining. For long-term procurement security, MC33172 series parts offer superior stock levels.

Q5: Do all substitute parts maintain RoHS3 and MSL Level 1 compliance?

Yes. TL072CPSR, MC33172D, and MC33172DT all maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original TL072ACPSR.
