Key Parameters

Substitute Part Grouping Explanation

Substitution for the TPS76833QPWPG4 is determined by strict equivalence across the following critical parameters:

• Output voltage configuration (Positive, Fixed 3.3V)
• Output current rating (1A)
• Maximum input voltage (10V)
• Voltage dropout specification (0.58V @ 1A)
• Control features (Enable, Power Good)
• Protection features (Over Current, Over Temperature, Reverse Polarity)
• Package type (20-PowerTSSOP)
• Operating temperature range (-40°C to 125°C)
• Compliance certifications (ROHS3, REACH Unaffected)

The TPS76833QPWP qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is packaging format (Tube vs. original specification) and product status (Active vs. Discontinued).

Parameter Comparison

Engineering Selection Recommendations

The TPS76833QPWP is a direct functional equivalent to the TPS76833QPWPG4. Both devices share identical electrical specifications, thermal characteristics, and protection mechanisms. The substitute part maintains full compliance with ROHS3 and REACH requirements.

The primary advantage of selecting TPS76833QPWP is its Active product status, ensuring continued availability and supply chain reliability. The original TPS76833QPWPG4 is discontinued at DiGi Electronics, making the substitute the appropriate choice for new designs and ongoing production requirements.

Both parts are qualified for the same operating environment (-40°C to 125°C) and deliver equivalent performance in 3.3V regulated power applications requiring 1A output current with integrated enable and power-good monitoring functions.

Frequently Asked Questions (FAQ)

Q: Can TPS76833QPWP be used as a direct replacement for TPS76833QPWPG4?

A: Yes. Both parts are electrically and mechanically identical. They share the same output voltage (3.3V), output current (1A), dropout voltage (0.58V @ 1A), control features, protection mechanisms, and 20-PowerTSSOP package configuration. The substitute is currently in active production status.

Q: What is the difference between the two part numbers?

A: The primary difference is packaging format and product lifecycle status. TPS76833QPWPG4 is discontinued, while TPS76833QPWP is active and supplied in Tube packaging. Electrical performance and pin configuration are identical.

Q: Are there any thermal or reliability differences between these parts?

A: No. Both devices operate across the same temperature range (-40°C to 125°C) and include identical protection features for over-current, over-temperature, and reverse polarity conditions. Quiescent current, PSRR, and all electrical specifications are equivalent.

Q: Is the 20-PowerTSSOP package compatible with existing PCB layouts?

A: Yes. Both parts use the 20-PowerTSSOP package (0.173" width, 4.40mm). PCB footprints, solder reflow profiles, and assembly processes remain unchanged between the original and substitute part.

Q: What compliance certifications apply to the substitute part?

A: TPS76833QPWP maintains ROHS3 compliance and REACH Unaffected status, matching the original part's regulatory requirements.
