TLC075AIN Equivalent & Substitute Parts

Part Overview

The TLC075AIN is a CMOS operational amplifier integrated circuit manufactured by Texas Instruments, configured as a 4-circuit amplifier in a 16-DIP through-hole package. This device is classified as Last Time Buy, indicating discontinued production with limited remaining inventory. The TLC075AIN operates across a wide supply voltage range of 4.5V to 16V and is suitable for applications requiring low input bias current and low input offset voltage characteristics typical of CMOS amplifier designs.

Identification of equivalent and substitute parts is necessary due to the Last Time Buy status of the TLC075AIN. Alternative components with identical electrical performance characteristics and compatible functional specifications enable continued system design and production without redesign constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC075AIN is determined by electrical parameter equivalence across all specified performance characteristics. The substitute part must satisfy the following criteria:

Electrical Performance Equivalence:

• Amplifier Type: CMOS
• Number of Circuits: 4
• 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 (x4 Channels)
• Current - Output / Channel: 57 mA
• Voltage - Supply Span: 4.5 V to 16 V
• Operating Temperature Range: -40°C to 125°C

Regulatory Compliance:

• RoHS3 Compliant
• REACH Unaffected
• ECCN: EAR99

The TLC074AIDR meets all electrical performance specifications and regulatory requirements. The primary distinction between the main part and substitute is the package format and mounting technology: the TLC075AIN uses through-hole 16-DIP packaging, while the TLC074AIDR uses surface-mount 14-SOIC packaging. This difference necessitates circuit board redesign for PCB layout and assembly process modifications.

Parameter Comparison

Engineering Selection Recommendations

The TLC074AIDR is electrically equivalent to the TLC075AIN across all specified performance parameters. Both devices are manufactured by Texas Instruments and maintain identical electrical characteristics including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current capability, and operating temperature range.

The TLC074AIDR holds Active product status, ensuring continued availability and manufacturing support, whereas the TLC075AIN is designated Last Time Buy with limited inventory. Both components satisfy ROHS3 compliance and REACH regulatory requirements.

The primary engineering consideration for substitution is the package format transition from through-hole 16-DIP to surface-mount 14-SOIC. This change requires circuit board redesign, including PCB footprint modification, trace routing adjustments, and assembly process changes from through-hole insertion to surface-mount placement and reflow soldering. No electrical circuit modifications are required.

Frequently Asked Questions (FAQ)

Q: Are the TLC075AIN and TLC074AIDR electrically interchangeable?

A: Yes. Both devices are CMOS 4-circuit amplifiers with identical electrical specifications including 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 across 4 channels), output current per channel (57 mA), and operating temperature range (-40°C to 125°C). Supply voltage range is identical at 4.5V to 16V.

Q: What is the primary difference between these two parts?

A: The TLC075AIN uses through-hole 16-DIP packaging for traditional PCB insertion assembly, while the TLC074AIDR uses surface-mount 14-SOIC packaging for automated surface-mount assembly. The TLC074AIDR is also in Active product status, whereas the TLC075AIN is Last Time Buy.

Q: Can I use the TLC074AIDR as a direct replacement without circuit modifications?

A: Electrical circuit modifications are not required. However, PCB layout redesign is necessary to accommodate the different package format. The 16-DIP through-hole footprint must be replaced with a 14-SOIC surface-mount footprint, and assembly processes must transition from through-hole insertion to surface-mount reflow soldering.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the TLC075AIN and TLC074AIDR are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic components.

Q: Why should I consider the TLC074AIDR if the TLC075AIN is available?

A: The TLC075AIN is designated Last Time Buy, indicating discontinued production with limited remaining inventory. The TLC074AIDR maintains Active product status with ongoing manufacturing support and availability, making it suitable for long-term production requirements.

Q: What is the pin count difference between these packages?

A: The TLC075AIN uses a 16-pin DIP package, while the TLC074AIDR uses a 14-pin SOIC package. The functional circuit remains identical; the package size reduction reflects surface-mount technology optimization.
