TPS71433DRVR Equivalent & Substitute Parts

Part Overview

The TPS71433DRVR is a linear voltage regulator IC from Texas Instruments designed for positive fixed 3.3V output at 80mA in a 6-WSON (2x2) surface mount package. This part is classified as Last Time Buy, indicating it is being phased out. Finding equivalent or substitute parts is necessary to ensure design continuity and long-term supply chain reliability for applications requiring this voltage regulation topology.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS71433DRVR are identified based on the following critical parameters that determine functional compatibility:

• Output voltage: 3.3V fixed
• Output current capability: 80mA
• Package type: 6-WSON (2x2) / 6-WDFN Exposed Pad
• Surface mount configuration
• Operating temperature range: -40°C ~ 125°C
• RoHS3 compliance

Two substitute parts meet these core criteria with variations in input voltage rating, dropout voltage, and packaging format. The substitutes maintain identical output specifications and thermal operating range, ensuring drop-in compatibility for most applications within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the TPS71433DRVR, the following selection criteria apply:

TPS71433DRVT is a parametric equivalent offering identical electrical specifications and packaging. This part maintains the same input voltage maximum (10V), dropout voltage (1.3V @ 80mA), and control features. The primary advantage is Active product status, ensuring continued availability and manufacturing support compared to the Last Time Buy status of the original part.

TPS715A33DRVR is the manufacturer-recommended substitute from Texas Instruments. This part provides enhanced specifications including higher maximum input voltage (24V) and improved dropout voltage (1.12V @ 80mA). It includes additional protection features (Reverse Polarity protection) and maintains Active product status. This part is suitable for applications requiring higher input voltage tolerance or improved efficiency due to lower dropout characteristics. Packaging is available in Cut Tape and Digi-Reel formats.

Selection between the two substitutes depends on input voltage requirements and supply chain packaging preferences. Both parts maintain full compatibility with the original part's output specifications, thermal range, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can TPS71433DRVT be used as a direct replacement for TPS71433DRVR?

A: Yes. The TPS71433DRVT is a parametric equivalent with identical output voltage (3.3V), output current (80mA), input voltage maximum (10V), dropout voltage (1.3V @ 80mA), and package configuration (6-WDFN). The primary difference is product status (Active vs. Last Time Buy) and packaging format (Tape & Reel for both).

Q: What are the advantages of TPS715A33DRVR over TPS71433DRVR?

A: The TPS715A33DRVR offers higher maximum input voltage (24V vs. 10V), lower dropout voltage (1.12V vs. 1.3V @ 80mA), and additional reverse polarity protection. It maintains the same output voltage, current, and package type. Active product status ensures long-term availability.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 6-WSON (2x2) / 6-WDFN Exposed Pad package with identical pinout and surface mount configuration, enabling direct PCB-level substitution.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging is supplied on continuous tape for automated pick-and-place assembly. Cut Tape and Digi-Reel formats provide smaller quantities on cut tape segments. Electrical performance and component specifications are identical; packaging format affects supply chain logistics and minimum order quantities.

Q: Can TPS715A33DRVR be used in applications designed for 10V maximum input?

A: Yes. The TPS715A33DRVR is rated for 24V maximum input, which exceeds the 10V requirement. It will operate correctly in applications with lower input voltage specifications. The improved dropout voltage provides additional performance margin.

Q: Are all parts RoHS3 compliant?

A: Yes. TPS71433DRVR, TPS71433DRVT, and TPS715A33DRVR are all ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements.
