TPS76833QPWPREP Equivalent & Substitute Parts

Part Overview

The TPS76833QPWPREP is a linear voltage regulator IC manufactured by Texas Instruments, designed for positive fixed 3.3V output applications. This Surface Mount device delivers 1A output current in a 20-PowerTSSOP package and is classified as Active product status. The device integrates Enable and Power Good control features alongside Over Current, Over Temperature, and Reverse Polarity protection. Finding equivalent substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate different packaging or inventory requirements while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitute parts for the TPS76833QPWPREP are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Parameters: Output voltage (3.3V fixed), output current (1A), input voltage maximum (10V), voltage dropout (0.58V @ 1A), quiescent current (125 µA), PSRR (60dB @ 1kHz), control features (Enable, Power Good), and protection features (Over Current, Over Temperature, Reverse Polarity) must remain identical.

Mechanical Parameters: Package type (20-PowerTSSOP), mounting type (Surface Mount), and physical dimensions (0.173", 4.40mm Width) must match exactly.

Compliance & Status: Product status must be Active, RoHS3 compliance must be maintained, and MSL rating must be 2 (1 Year) or better.

Packaging Variation: The only allowable variation is in distribution packaging format (Tape & Reel versus Cut Tape & Digi-Reel), which does not affect electrical or mechanical performance or PCB integration.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS76833QPWPREP and TPS76833QPWPR are Active status products manufactured by Texas Instruments with identical electrical specifications and mechanical packaging. Selection between these parts should be based on distribution packaging requirements and inventory availability.

The TPS76833QPWPREP is supplied in Tape & Reel format, suitable for high-volume automated assembly operations. The TPS76833QPWPR is supplied in Cut Tape and Digi-Reel format, appropriate for lower-volume applications or when smaller quantity increments are required.

Both parts maintain ROHS3 compliance and MSL rating of 2 (1 Year), ensuring equivalent environmental and moisture handling requirements. No additional qualification or testing is required when substituting between these parts, as all critical parameters remain constant.

Frequently Asked Questions (FAQ)

Q: Can TPS76833QPWPR be used as a direct replacement for TPS76833QPWPREP?

A: Yes. Both parts are electrically and mechanically identical. The only difference is distribution packaging format (Tape & Reel versus Cut Tape & Digi-Reel). PCB design, schematic, and assembly processes require no modification.

Q: What determines if a part is a valid substitute for the TPS76833QPWPREP?

A: Valid substitutes must match all electrical parameters (output voltage, current, dropout voltage, quiescent current, PSRR, control features, protection features, operating temperature range), mechanical parameters (package type, dimensions, mounting type), and compliance status (Active product status, ROHS3 compliance, MSL rating).

Q: Does packaging format affect circuit performance?

A: No. Tape & Reel and Cut Tape & Digi-Reel are distribution formats only. They do not affect electrical performance, PCB footprint compatibility, or device functionality.

Q: Are there any compatibility concerns when switching between these substitute parts?

A: No compatibility concerns exist. Both parts use identical 20-PowerTSSOP packaging with matching pinout, electrical characteristics, and thermal properties. Assembly equipment settings and PCB layouts remain unchanged.

Q: What is the significance of the Base Product Number TPS76833?

A: The Base Product Number identifies the core device design. Both the main part and substitute share the same base number, confirming they are the same device with only packaging variation.
