TLC072IP Equivalent & Substitute Parts

Part Overview

The TLC072IP is a general-purpose operational amplifier featuring two independent circuits in an 8-pin DIP package. This device is designed for applications requiring low-power, general-purpose amplification with a gain-bandwidth product of 10 MHz and a slew rate of 19 V/µs. The TLC072IP is currently in Last Time Buy status, indicating that the manufacturer has discontinued or will discontinue production. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain supply chain reliability for new production runs and long-term support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC072IP is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 2
• Slew Rate: 19 V/µs
• Gain Bandwidth Product: 10 MHz
• Current - Input Bias: 1.5 pA
• Voltage - Input Offset: 390 µV
• Current - Supply: 2.1 mA (x2 Channels)
• Current - Output / Channel: 57 mA
• Voltage - Supply Span: 4.5 V to 16 V
• Operating Temperature Range: -40°C to 125°C

Mechanical Compatibility Criteria:

• Package / Case configuration
• Mounting Type (Through Hole vs. Surface Mount)
• Pin count and pinout compatibility

The TLC072IDR is identified as the manufacturer-recommended substitute. This part maintains identical electrical specifications while offering a different package configuration (8-SOIC surface mount versus 8-DIP through hole). The TLC072IDR is in Active product status, ensuring continued availability and long-term supply chain support.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TLC072IDR

The TLC072IDR is the manufacturer-recommended substitute for the TLC072IP. Both parts share the identical base product number (TLC072) and maintain all electrical specifications without deviation. The TLC072IDR is currently in Active product status, ensuring ongoing availability and manufacturing support.

Key Considerations for Selection:

1. Package Configuration: The TLC072IDR uses an 8-SOIC surface-mount package, whereas the TLC072IP uses an 8-DIP through-hole package. PCB layout and assembly process compatibility must be evaluated based on your manufacturing infrastructure.

2. Compliance Status: Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for equivalent applications.

3. Supply Chain Continuity: The TLC072IP is in Last Time Buy status, indicating limited future availability. The TLC072IDR's Active status provides long-term supply chain reliability for ongoing production requirements.

4. Electrical Equivalence: All electrical parameters—including slew rate, gain-bandwidth product, input bias current, input offset voltage, supply current, output current, and operating temperature range—are identical between the two parts. Direct functional substitution is supported without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the TLC072IDR be used as a direct replacement for the TLC072IP in existing designs?

A: The TLC072IDR is electrically equivalent to the TLC072IP across all specified parameters. However, the package difference (8-SOIC surface mount versus 8-DIP through hole) requires PCB layout modification. If your design uses through-hole assembly, the TLC072IDR requires a different footprint and assembly process.

Q: What is the significance of the TLC072IP being in Last Time Buy status?

A: Last Time Buy status indicates that Texas Instruments has announced the end of production for the TLC072IP. Existing inventory will be depleted, and the part will no longer be manufactured. Transitioning to the TLC072IDR ensures continued access to the TLC072 architecture beyond the Last Time Buy window.

Q: Are the electrical specifications identical between TLC072IP and TLC072IDR?

A: Yes. Both parts maintain identical specifications for slew rate (19 V/µs), gain-bandwidth product (10 MHz), input bias current (1.5 pA), input offset voltage (390 µV), supply current (2.1 mA per channel), output current (57 mA per channel), and operating temperature range (-40°C to 125°C). The only differences are packaging and mounting type.

Q: What are the compliance certifications for both parts?

A: Both the TLC072IP and TLC072IDR are ROHS3 compliant and REACH Unaffected. These certifications apply equally to both variants, supporting equivalent regulatory compliance in applications requiring these standards.

Q: Does the TLC072IDR have better availability than the TLC072IP?

A: Yes. The TLC072IDR is in Active product status with significantly higher inventory (17,600 pieces in stock versus 655 pieces for the TLC072IP). The Active status ensures ongoing manufacturing and supply chain support.

Q: Can I use the TLC072IDR in a through-hole socket designed for the TLC072IP?

A: No. The TLC072IDR uses an 8-SOIC surface-mount package with a different pin pitch and footprint. It cannot be inserted into a through-hole DIP socket. PCB redesign is required to accommodate the surface-mount package.

Q: Are there any thermal or power dissipation differences between the two packages?

A: The electrical specifications, including supply current and output current, are identical. However, the 8-SOIC package has different thermal characteristics than the 8-DIP package. Thermal analysis specific to your application and PCB layout is necessary to ensure adequate heat dissipation in the target environment.
