TLC075CPWP Equivalent & Substitute Parts

Part Overview

The TLC075CPWP 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 Last Time Buy, indicating discontinued production with limited inventory availability. The TLC075CPWP operates across a wide supply voltage range of 4.5V to 16V and is suitable for applications requiring low input bias current and moderate bandwidth performance. Due to its Last Time Buy status, identification of functionally equivalent substitute components is necessary for design continuity and long-term product support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC075CPWP is determined by electrical and functional equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier Type: CMOS topology
• Number of Circuits: 4 independent amplifier channels
• 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 (x4 Channels)
• Output Current per Channel: 57 mA
• Supply Voltage Range: 4.5V to 16V minimum and maximum
• Operating Temperature Range: 0°C to 70°C

Mechanical and Compliance Criteria:

• Surface Mount technology
• RoHS3 Compliance
• REACH Unaffected status
• ECCN EAR99 classification

The TLC074CDR meets all electrical specifications and compliance requirements, with the primary distinction being package configuration and moisture sensitivity rating.

Engineering Selection Recommendations

TLC074CDR as Primary Substitute:

The TLC074CDR is the manufacturer-recommended substitute for the TLC075CPWP. This device maintains complete electrical equivalence across all operational parameters including amplifier topology, gain bandwidth product, slew rate, input characteristics, supply current, and output current specifications. Both devices operate identically within the 4.5V to 16V supply range and 0°C to 70°C temperature window.

Product Status Advantage:

The TLC074CDR carries Active product status, ensuring continued availability and long-term supply security. This contrasts with the TLC075CPWP Last Time Buy designation, which indicates production discontinuation. Selection of the TLC074CDR eliminates supply chain risk associated with obsolescence.

Compliance and Certification:

Both devices maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for equivalent applications. The TLC074CDR provides improved moisture sensitivity rating (MSL 1 with unlimited shelf life) compared to the TLC075CPWP (MSL 2 with 1-year shelf life), offering enhanced storage stability and reduced handling constraints.

Package Consideration:

The primary physical difference is package configuration: TLC075CPWP uses 20-PowerTSSOP while TLC074CDR uses 14-SOIC. PCB layout modifications are required for package substitution. The 14-SOIC package occupies less board area and may provide thermal management advantages in certain applications due to reduced package footprint.

Frequently Asked Questions (FAQ)

Q: Are the TLC075CPWP and TLC074CDR electrically interchangeable?

A: Yes. Both devices are CMOS four-channel operational amplifiers with identical electrical specifications: 19 V/µs slew rate, 10 MHz gain bandwidth product, 1.5 pA input bias current, 390 µV input offset voltage, 2.1 mA supply current, and 57 mA output current per channel. Supply voltage range (4.5V to 16V) and operating temperature (0°C to 70°C) are identical.

Q: What is the primary reason to substitute the TLC075CPWP?

A: The TLC075CPWP is designated Last Time Buy, indicating production discontinuation. The TLC074CDR maintains Active status, ensuring continued availability and eliminating obsolescence risk.

Q: Do I need to modify my PCB design to use the TLC074CDR?

A: Yes. The TLC075CPWP uses a 20-pin PowerTSSOP package while the TLC074CDR uses a 14-pin SOIC package. PCB layout, footprint, and pin routing require redesign. Pin assignments differ between packages and must be verified against device datasheets.

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

A: The TLC075CPWP has MSL 2 rating with 1-year shelf life, requiring controlled storage conditions. The TLC074CDR has MSL 1 rating with unlimited shelf life, providing superior storage stability and reduced handling constraints.

Q: Can I use the TLC074CDR in existing designs without circuit modification?

A: Electrical circuit operation is identical; however, PCB layout modification is mandatory due to different package types. Schematic connections remain the same, but physical placement and routing differ significantly.

Q: Are both devices RoHS compliant?

A: Yes. Both TLC075CPWP and TLC074CDR are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements.

Q: What packaging formats are available for the TLC074CDR?

A: The TLC074CDR is supplied in Cut Tape (CT) and Digi-Reel® formats, offering flexibility for both manual assembly and automated production environments.
