TLC084CPWP Equivalent & Substitute Parts

Part Overview

The TLC084CPWP is a general-purpose 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 availability. The TLC084CPWP 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.

Identification of equivalent and substitute parts is necessary due to the Last Time Buy status of the TLC084CPWP. Alternative configurations within the TLC084 base product family provide functionally identical electrical performance while offering different packaging options and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC084CPWP is determined by electrical and functional equivalence within the TLC084 base product family. All substitute parts must maintain identical performance across the following critical parameters:

• Four independent amplifier circuits
• Slew rate of 19 V/µs
• Gain bandwidth product of 10 MHz
• Input bias current of 3 pA
• Input offset voltage of 390 µV
• Supply current of 1.9 mA across four channels
• Output current per channel of 57 mA
• Supply voltage range of 4.5V to 16V
• Operating temperature range of 0°C to 70°C

The primary difference between the main part and substitute parts lies in packaging configuration and product availability status. The TLC084CPWP uses a 20-pin PowerTSSOP package, while the TLC084CDR uses a 14-pin SOIC package. Both packages are surface-mount configurations suitable for automated assembly. The electrical specifications remain identical across all variants.

Parameter Comparison

Engineering Selection Recommendations

The TLC084CDR serves as the primary substitute for the TLC084CPWP based on the following engineering criteria:

Electrical Equivalence: All electrical parameters are identical between the two parts. The TLC084CDR maintains the same slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage specifications as the TLC084CPWP.

Compliance and Certifications: Both parts are ROHS3 compliant and REACH unaffected, meeting the same regulatory requirements. Both carry the same ECCN and HTSUS classifications.

Product Status: The TLC084CDR holds Active product status with significantly higher inventory availability (10,246 pieces) compared to the Last Time Buy status of the TLC084CPWP (1,077 pieces). This availability advantage makes the TLC084CDR the preferred choice for new designs and ongoing production requirements.

Moisture Sensitivity: The TLC084CDR features Moisture Sensitivity Level 1 with unlimited shelf life, compared to the TLC084CPWP's MSL 2 with one-year shelf life. This provides superior long-term storage characteristics.

Package Considerations: The TLC084CDR uses a 14-pin SOIC package with a narrower width (3.90mm) compared to the 20-pin PowerTSSOP package of the TLC084CPWP (4.40mm). PCB layout modifications are required when transitioning between these packages.

Frequently Asked Questions (FAQ)

Q: Are the TLC084CPWP and TLC084CDR electrically identical?

A: Yes. Both parts share identical electrical specifications including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and operating temperature range. They are functionally equivalent general-purpose operational amplifiers.

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

A: The primary difference is packaging. The TLC084CPWP uses a 20-pin PowerTSSOP package, while the TLC084CDR uses a 14-pin SOIC package. The TLC084CDR also has Active product status with higher availability and superior moisture sensitivity characteristics.

Q: Can I directly replace the TLC084CPWP with the TLC084CDR on my PCB?

A: Direct replacement requires PCB layout modifications due to different package pinouts and dimensions. The 20-pin PowerTSSOP and 14-pin SOIC packages have different pin configurations and footprints. A new PCB layout is necessary for the TLC084CDR.

Q: Why is the TLC084CPWP marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this specific package variant. The TLC084CDR represents the active product offering within the TLC084 family.

Q: What are the moisture sensitivity implications for storage?

A: The TLC084CPWP (MSL 2) requires controlled storage conditions with a one-year shelf life limit. The TLC084CDR (MSL 1) has unlimited shelf life, providing greater flexibility for inventory management and long-term storage without moisture-related degradation concerns.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the TLC084CPWP and TLC084CDR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Which part should I specify for new designs?

A: The TLC084CDR is the recommended choice for new designs due to its Active product status, higher availability, superior moisture sensitivity rating, and identical electrical performance.
