TLC074AIPWP Equivalent & Substitute Parts

Part Overview

The TLC074AIPWP is a CMOS operational amplifier integrated circuit containing four independent amplifier circuits in a 20-pin PowerTSSOP surface mount package. This device is classified as obsolete, which necessitates identification of equivalent substitute components for ongoing design support and procurement requirements. The TLC074AIPWP maintains full electrical and functional compatibility with active alternative configurations within the TLC074 product family.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the TLC074AIPWP are identified based on electrical parameter equivalence within the TLC074 base product family. The substitution criteria are strictly limited to the following parameters:

• 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

The TLC074AID meets all electrical parameter requirements for functional substitution. The primary difference between these components is the package configuration: the TLC074AIPWP uses a 20-pin PowerTSSOP package, while the TLC074AID uses a 14-pin SOIC package. Both devices are manufactured by Texas Instruments and maintain identical electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The TLC074AID is the designated manufacturer-recommended substitute for the obsolete TLC074AIPWP. Both components maintain identical electrical specifications and are manufactured by Texas Instruments under the same base product number TLC074.

The TLC074AID offers the following advantages for component selection:

• Active product status ensures ongoing availability and manufacturing support
• Improved moisture sensitivity level (MSL 1 vs. MSL 2) provides extended shelf life without moisture bake-out requirements
• ROHS3 and REACH compliance maintained across both components
• All electrical parameters remain equivalent, ensuring functional interchangeability in circuit applications

The primary consideration for substitution is package compatibility. The TLC074AID uses a 14-pin SOIC package compared to the 20-pin PowerTSSOP package of the TLC074AIPWP. PCB layout modifications are required to accommodate the different package footprint and pin configuration.

Frequently Asked Questions (FAQ)

Q: Are the TLC074AIPWP and TLC074AID electrically interchangeable?

A: Yes. Both components share identical electrical specifications including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and operating temperature range. Functional interchangeability is confirmed across all provided electrical parameters.

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

A: The primary difference is the package configuration. The TLC074AIPWP uses a 20-pin PowerTSSOP package, while the TLC074AID uses a 14-pin SOIC package. This difference requires PCB layout redesign for substitution.

Q: Why is the TLC074AIPWP classified as obsolete?

A: The TLC074AIPWP is listed as obsolete by the manufacturer. The TLC074AID maintains active product status and is the recommended alternative for new designs and ongoing procurement.

Q: Do both components meet RoHS and REACH compliance requirements?

A: Yes. Both the TLC074AIPWP and TLC074AID are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the difference in moisture sensitivity levels between these components?

A: The TLC074AIPWP has MSL 2 (1 Year), requiring moisture bake-out after one year of storage. The TLC074AID has MSL 1 (Unlimited), eliminating moisture bake-out requirements and providing extended shelf life.

Q: Can I use the TLC074AID as a direct replacement without circuit modifications?

A: Electrical substitution is direct. However, PCB layout modifications are required due to the different package footprint and pin configuration between the 20-pin PowerTSSOP and 14-pin SOIC packages.

Q: Are both components available from Texas Instruments?

A: The TLC074AID is actively manufactured by Texas Instruments. The TLC074AIPWP is obsolete and no longer in active production, though existing inventory may be available through component distributors.
