Substitute Part Grouping Explanation

Substitution for the TPS73733DRVT is determined by electrical and mechanical parameter equivalence. The primary substitute, TPS73733DRVR, maintains identical electrical specifications across all critical parameters: fixed 3.3V output, 1A output current capacity, 5.5V maximum input voltage, 0.5V maximum dropout voltage at 1A, 400 µA quiescent current, and identical protection features (Over Current, Over Temperature, Reverse Polarity). Both parts operate across the same temperature range (-40°C to 125°C) and use the same 6-WSON (2x2) package footprint.

The key differentiator between these parts is packaging format: TPS73733DRVT is supplied in Tape & Reel (TR) format, while TPS73733DRVR is supplied in Cut Tape (CT) & Digi-Reel® format. This distinction affects procurement and handling but does not impact electrical or mechanical compatibility in the final application.

Parameter Comparison

Engineering Selection Recommendations

The TPS73733DRVR is a direct electrical and mechanical substitute for the TPS73733DRVT. Both parts share identical electrical performance specifications and are housed in the same 6-WSON (2x2) package with exposed pad, ensuring PCB layout and thermal management compatibility.

The primary consideration for selection is product lifecycle status. The TPS73733DRVT carries Last Time Buy status, indicating limited availability and imminent discontinuation. The TPS73733DRVR maintains Active product status with significantly higher inventory availability (17,100 pcs vs. 8,841 pcs), making it the preferred choice for new designs and ongoing production requirements.

Both parts maintain identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and equivalent ECCN/HTSUS classifications. Moisture sensitivity level is identical at MSL 2 (1 Year) for both variants.

Frequently Asked Questions (FAQ)

Q: Are TPS73733DRVT and TPS73733DRVR electrically identical?

A: Yes. Both parts deliver identical electrical performance: 3.3V fixed output, 1A output current, 0.5V maximum dropout at 1A, 400 µA quiescent current, and identical protection features (Over Current, Over Temperature, Reverse Polarity). PSRR performance and operating temperature range are also identical.

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

A: The difference is packaging format only. TPS73733DRVT is supplied in Tape & Reel (TR) format, while TPS73733DRVR is supplied in Cut Tape (CT) & Digi-Reel® format. This affects procurement and component handling but does not impact electrical or mechanical performance in the final application.

Q: Can I use TPS73733DRVR as a direct replacement on my PCB?

A: Yes. Both parts use the identical 6-WSON (2x2) package footprint with exposed pad. PCB layout, thermal management, and electrical connections remain unchanged. No design modifications are required.

Q: Why should I consider switching from TPS73733DRVT to TPS73733DRVR?

A: The TPS73733DRVT is Last Time Buy status with limited remaining inventory. The TPS73733DRVR is Active status with substantially higher availability, ensuring supply chain continuity for current and future production.

Q: Are compliance certifications identical?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. Moisture sensitivity level is MSL 2 (1 Year) for both variants.
