TLC082AIP Equivalent & Substitute Parts

Part Overview

The TLC082AIP is a general-purpose operational amplifier featuring two independent circuits in an 8-pin DIP package. This device is manufactured by Texas Instruments and is classified as a linear amplifier suitable for general-purpose applications requiring dual-channel amplification. The TLC082AIP is currently designated as Last Time Buy, indicating that the through-hole variant is being phased out. Identifying equivalent substitute parts is necessary to ensure design continuity and support long-term production requirements, particularly for applications transitioning to surface-mount technology or requiring active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC082AIP 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: 3 pA
• Voltage - Input Offset: 390 µV
• Current - Supply: 1.9 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:

• Base Product Number: TLC082
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The TLC082AIDR is identified as a manufacturer-recommended substitute. This part maintains identical electrical specifications while differing in mounting technology (surface mount versus through hole) and packaging format (8-SOIC versus 8-DIP). The substitute is suitable for applications where surface-mount assembly is employed or where active product status is required.

Engineering Selection Recommendations

TLC082AIDR Selection Criteria:

The TLC082AIDR is the manufacturer-recommended substitute for the TLC082AIP. Selection of this part is appropriate under the following conditions:

1. Product Status Transition: The TLC082AIP is designated Last Time Buy, indicating limited future availability. The TLC082AIDR maintains Active product status, ensuring long-term supply continuity and support.

2. Assembly Technology Compatibility: The TLC082AIDR employs surface-mount technology (8-SOIC package) and is suitable for designs utilizing automated surface-mount assembly processes. The TLC082AIP through-hole variant is appropriate only for through-hole assembly or mixed-technology boards.

3. Regulatory Compliance: Both parts maintain identical ROHS3 compliance and REACH Unaffected status, satisfying equivalent environmental and regulatory requirements.

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

5. Packaging Consideration: PCB layout and footprint design must accommodate the 8-SOIC package format (0.154" width) rather than the 8-DIP format (0.300" width). This represents the primary design consideration for substitution.

Frequently Asked Questions (FAQ)

Q: Can the TLC082AIDR be used as a direct replacement for the TLC082AIP in existing designs?

A: Electrical substitution is direct; all electrical parameters are identical. However, mechanical substitution requires PCB redesign to accommodate the 8-SOIC surface-mount package instead of the 8-DIP through-hole package. The footprints are not interchangeable without layout modification.

Q: What is the primary reason for substituting the TLC082AIP with the TLC082AIDR?

A: The TLC082AIP is designated Last Time Buy, indicating discontinuation of the through-hole variant. The TLC082AIDR maintains Active product status and ensures continued availability. Additionally, surface-mount technology offers manufacturing advantages in modern production environments.

Q: Are the electrical specifications identical between TLC082AIP and TLC082AIDR?

A: Yes. Both parts share identical specifications for slew rate (19 V/µs), gain bandwidth product (10 MHz), input bias current (3 pA), input offset voltage (390 µV), supply current (1.9 mA per channel), output current (57 mA per channel), and operating temperature range (-40°C to 125°C). No circuit performance differences exist.

Q: What are the package dimension differences between these parts?

A: The TLC082AIP uses an 8-DIP package with 0.300" (7.62 mm) width, designed for through-hole mounting. The TLC082AIDR uses an 8-SOIC package with 0.154" (3.90 mm) width, designed for surface-mount assembly. These packages are not pin-compatible without adapter solutions.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the TLC082AIP and TLC082AIDR are ROHS3 Compliant and REACH Unaffected, satisfying identical environmental and regulatory standards.

Q: Which part should be selected for new designs?

A: The TLC082AIDR is the appropriate selection for new designs. It maintains Active product status, ensuring long-term availability and manufacturer support. The TLC082AIP should be reserved for existing designs requiring through-hole assembly or for applications with established supply chains.
