TL072ACPSRG4 Equivalent & Substitute Parts

Part Overview

The TL072ACPSRG4 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, indicating discontinued production and limited availability through standard distribution channels. The part operates across a supply voltage range of 10V to 30V with a slew rate of 13V/µs and gain bandwidth product of 3 MHz, making it suitable for precision analog signal processing applications requiring low input bias current (65 pA) and low input offset voltage (3 mV).

Due to its obsolete status, identifying functionally compatible substitute components is essential for design continuity, production planning, and long-term system reliability. Active alternatives with equivalent electrical and mechanical characteristics are available from alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL072ACPSRG4 is determined by the following critical parameters that must be maintained or exceeded in alternative components:

Mechanical Compatibility:

• Dual-channel configuration (2 circuits minimum)
• Surface mount package type
• 8-pin SOIC package footprint compatibility

Electrical Performance Criteria:

• Supply voltage range must encompass the original 10V to 30V specification
• Slew rate of 13V/µs or greater
• Gain bandwidth product of 3 MHz or greater
• Input bias current of 65 pA or lower
• Input offset voltage of 3 mV or lower

Regulatory & Compliance:

• RoHS3 compliance
• MSL rating of 1 (Unlimited)
• REACH unaffected status

The substitute parts identified (MC33172D and MC33172DT) are both manufactured by STMicroelectronics and share the same base product number (MC33172). Both variants meet the mechanical package requirements and regulatory compliance standards. However, these substitutes operate as general-purpose amplifiers rather than J-FET input types, with different electrical characteristics that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Active Product Availability: Both MC33172D and MC33172DT are active products with substantial inventory availability (100,400 pcs and 45,300 pcs respectively), providing reliable long-term sourcing compared to the obsolete TL072ACPSRG4.

Regulatory Compliance: All three components maintain ROHS3 compliance, MSL rating of 1 (Unlimited), and REACH unaffected status, ensuring compatibility with current environmental and regulatory requirements.

Packaging Differentiation: MC33172D is supplied in tube packaging, while MC33172DT is available in cut tape and Digi-Reel® formats. Selection between these variants depends on production volume and assembly line requirements.

Electrical Performance Trade-offs: The MC33172 substitutes exhibit lower slew rate (2V/µs versus 13V/µs) and reduced gain bandwidth product (2.1 MHz versus 3 MHz). These differences must be evaluated against specific application bandwidth and transient response requirements. The MC33172 series provides superior input bias current performance (20 pA versus 65 pA) and lower input offset voltage (1 mV versus 3 mV), which may benefit precision measurement applications.

Package Footprint Consideration: The MC33172 variants use a narrower 8-SOIC package (0.154", 3.90mm width) compared to the TL072ACPSRG4 (0.209", 5.30mm width). PCB layout verification is required to confirm footprint compatibility with existing designs.

Temperature Range Extension: The MC33172 series operates across -40°C to 105°C, providing extended temperature coverage beyond the TL072ACPSRG4 specification of 0°C to 70°C.

Frequently Asked Questions (FAQ)

Q: Can MC33172D and MC33172DT be used interchangeably as substitutes for TL072ACPSRG4?

A: Both MC33172D and MC33172DT share identical electrical specifications and are functionally equivalent. The primary difference is packaging format: MC33172D is supplied in tube packaging, while MC33172DT is supplied in cut tape and Digi-Reel® formats. Selection depends on production volume and assembly equipment compatibility.

Q: What are the key electrical differences between TL072ACPSRG4 and MC33172 substitutes?

A: The TL072ACPSRG4 features J-FET input architecture with higher slew rate (13V/µs) and gain bandwidth product (3 MHz), while MC33172 variants are general-purpose amplifiers with lower slew rate (2V/µs) and gain bandwidth product (2.1 MHz). However, MC33172 provides superior input bias current (20 pA) and input offset voltage (1 mV) performance. Applications requiring high-speed transient response may not be suitable for MC33172 substitution.

Q: Are there package footprint compatibility issues when substituting MC33172 for TL072ACPSRG4?

A: Both components use 8-SOIC surface mount packages, but with different body widths: TL072ACPSRG4 is 0.209" (5.30mm) while MC33172 is 0.154" (3.90mm). PCB layout and footprint verification is required to confirm compatibility with existing designs. The narrower MC33172 package may require design modifications.

Q: Do MC33172D and MC33172DT meet the same regulatory and compliance standards as TL072ACPSRG4?

A: Yes. All three components are ROHS3 compliant, carry MSL rating of 1 (Unlimited), and maintain REACH unaffected status. Regulatory compliance is equivalent across all variants.

Q: What is the supply voltage compatibility between TL072ACPSRG4 and MC33172 substitutes?

A: TL072ACPSRG4 operates within 10V to 30V supply range, while MC33172 variants operate within 4V to 44V range. MC33172 provides broader supply voltage compatibility and can operate at lower minimum voltages. Existing 10V to 30V supply designs are fully compatible with MC33172 substitution.

Q: How does the extended operating temperature range of MC33172 affect substitution suitability?

A: MC33172 operates across -40°C to 105°C compared to TL072ACPSRG4 at 0°C to 70°C. This extended range provides additional design flexibility for applications requiring operation outside the original temperature specification. Applications limited to 0°C to 70°C operation are fully compatible with MC33172 substitution.

Q: What inventory considerations exist for TL072ACPSRG4 versus MC33172 substitutes?

A: TL072ACPSRG4 is obsolete with limited remaining inventory (779 pcs). MC33172D and MC33172DT are active products with substantial inventory (100,400 pcs and 45,300 pcs respectively), providing reliable long-term sourcing and production continuity.
