Substitute Part Grouping Explanation

Substitution eligibility for the TL072CPS is determined by strict equivalence across the following critical parameters:

Functional Equivalence Criteria:

• Amplifier Type: J-FET input architecture
• Number of Circuits: Dual (2) operational amplifiers per package
• Input Bias Current: 65 pA maximum
• Input Offset Voltage: 3 mV maximum
• Supply Voltage Range: 10 V to 30 V operation
• Slew Rate: 13 V/µs minimum
• Supply Current: 1.4 mA per channel maximum

Package Compatibility:

• Surface mount 8-SOIC configuration
• Pin-for-pin compatible footprint

Compliance Requirements:

• RoHS3 compliance
• MSL Level 1 rating

The TL072IDR meets all functional equivalence criteria and package requirements, qualifying as a direct substitute. The TL072IDR operates across an extended temperature range (-40°C to 85°C) compared to the TL072CPS (0°C to 70°C) and features improved gain bandwidth product (5.25 MHz versus 3 MHz), providing enhanced performance margins while maintaining full backward compatibility.

Engineering Selection Recommendations

TL072IDR Selection Rationale:

The TL072IDR is the recommended substitute for the TL072CPS based on the following engineering factors:

1. Product Status Alignment: The TL072CPS carries Last Time Buy status with finite inventory (2,178 pcs). The TL072IDR maintains Active product status with significantly higher availability (35,200 pcs), ensuring long-term supply chain continuity.

2. Functional Compatibility: Both devices share identical J-FET amplifier architecture, dual-circuit configuration, input bias current, input offset voltage, slew rate, and supply voltage specifications. All critical electrical parameters remain within specification for direct substitution.

3. Enhanced Performance Margin: The TL072IDR provides 75% higher gain bandwidth product (5.25 MHz versus 3 MHz), delivering improved frequency response characteristics while maintaining backward compatibility with existing circuit designs.

4. Extended Operating Range: The TL072IDR operates across -40°C to 85°C, encompassing the TL072CPS operating range (0°C to 70°C) and providing thermal margin for industrial and extended-temperature applications.

5. Compliance Certification: Both devices maintain ROHS3 compliance and MSL Level 1 rating, satisfying regulatory and manufacturing requirements without modification.

6. Package Compatibility: Both devices utilize 8-SOIC surface mount packages with identical pinout. The TL072IDR package width (3.90mm) is more compact than the TL072CPS (5.30mm), offering improved PCB layout density without requiring design changes.

Frequently Asked Questions (FAQ)

Q: Can the TL072IDR directly replace the TL072CPS without circuit modification?

A: Yes. The TL072IDR is pin-for-pin compatible with identical electrical specifications for all critical parameters: input bias current, input offset voltage, slew rate, supply voltage range, and supply current. No circuit redesign is required.

Q: What is the difference in package dimensions between these parts?

A: The TL072CPS uses an 8-SOIC package with 5.30mm width, while the TL072IDR uses an 8-SOIC package with 3.90mm width. Both maintain identical pinout and footprint compatibility. The TL072IDR's narrower package may provide improved PCB layout efficiency.

Q: Why does the TL072IDR have higher gain bandwidth product?

A: The TL072IDR specification lists 5.25 MHz gain bandwidth product compared to 3 MHz for the TL072CPS. This represents improved frequency response performance while maintaining all other electrical parameters within specification.

Q: Is the TL072IDR suitable for applications currently using TL072CPS?

A: Yes. The TL072IDR meets or exceeds all electrical specifications of the TL072CPS and operates across an extended temperature range. It is suitable for all applications currently using the TL072CPS, including audio amplification, precision instrumentation, and signal conditioning circuits.

Q: What is the inventory status difference between these parts?

A: The TL072CPS is Last Time Buy status with 2,178 pcs available. The TL072IDR is Active status with 35,200 pcs in stock, providing significantly greater availability for new production and long-term supply assurance.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the TL072CPS and TL072IDR are ROHS3 compliant with MSL Level 1 rating, meeting environmental and manufacturing standards without restriction.

Q: What is the temperature operating range difference?

A: The TL072CPS operates from 0°C to 70°C. The TL072IDR operates from -40°C to 85°C, providing extended low-temperature and high-temperature capability. Applications requiring operation below 0°C or above 70°C must use the TL072IDR.
