TPS77833DR Equivalent & Substitute Parts

Part Overview

The TPS77833DR is a linear voltage regulator IC from Texas Instruments designed for positive fixed 3.3V output applications. It delivers 750mA output current with integrated control features including Enable, Power Good, and Reset functions, along with comprehensive protection against overcurrent, overtemperature, and reverse polarity conditions. The device is actively manufactured and widely used in power management applications requiring stable 3.3V regulation from input sources up to 10V. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or packaging format preferences.

Substitute Part Grouping Explanation

The TPS77733DR qualifies as a parametric equivalent to the TPS77833DR based on strict alignment across all critical electrical and mechanical parameters. Substitution is valid when the following conditions are met:

Electrical Equivalence Criteria:

• Identical output voltage: 3.3V fixed
• Identical output current rating: 750mA
• Identical maximum input voltage: 10V
• Identical voltage dropout specification: 0.43V @ 750mA
• Identical quiescent current: 125 µA
• Identical PSRR performance: 60dB (1kHz)
• Identical control feature set: Enable, Power Good, Reset
• Identical protection mechanisms: Over Current, Over Temperature, Reverse Polarity
• Identical operating temperature range: -40°C ~ 125°C

Mechanical Equivalence Criteria:

• Identical package type: 8-SOIC (0.154", 3.90mm Width)
• Identical mounting technology: Surface Mount
• Identical pin configuration and footprint compatibility

Compliance Equivalence:

• Identical RoHS3 compliance status
• Identical MSL rating: 1 (Unlimited)
• Identical REACH and ECCN classifications

The primary distinction between these parts is packaging format: TPS77833DR is supplied in Tape & Reel (TR) format, while TPS77733DR is available in Cut Tape (CT) & Digi-Reel® format. This difference does not affect electrical performance or functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS77833DR and TPS77733DR are active products from Texas Instruments with full ROHS3 compliance and unlimited moisture sensitivity ratings, making them suitable for production environments without supply chain risk. Selection between these parts should be based on packaging and supply chain requirements:

TPS77833DR (Tape & Reel): Select when high-volume automated assembly processes require standard tape and reel packaging for pick-and-place equipment integration.

TPS77733DR (Cut Tape & Digi-Reel®): Select when lower-volume applications, manual assembly, or specific supplier logistics favor cut tape or Digi-Reel® packaging formats.

Both parts deliver identical electrical performance and functional characteristics. No design modifications, PCB layout changes, or firmware adjustments are required when substituting between these parts. Pin-to-pin compatibility is guaranteed, and thermal performance remains unchanged.

Frequently Asked Questions (FAQ)

Q: Can TPS77733DR replace TPS77833DR in existing designs? A: Yes. The TPS77733DR is a direct parametric equivalent with identical electrical specifications, output voltage, current rating, control features, protection mechanisms, and 8-SOIC package dimensions. No circuit modifications are required.

Q: What is the difference between these two parts? A: The only difference is packaging format. TPS77833DR is supplied in Tape & Reel (TR) format, while TPS77733DR is available in Cut Tape (CT) & Digi-Reel® format. Electrical performance and functionality are identical.

Q: Are there any thermal or performance differences? A: No. Both parts have identical voltage dropout specifications (0.43V @ 750mA), quiescent current (125 µA), PSRR (60dB at 1kHz), and operating temperature range (-40°C ~ 125°C).

Q: Do these parts have the same pin configuration? A: Yes. Both use the 8-SOIC package with identical pin assignments, footprint, and mechanical dimensions (0.154" × 3.90mm width).

Q: Are both parts RoHS compliant? A: Yes. Both TPS77833DR and TPS77733DR are ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity).

Q: Which part should I select for high-volume production? A: TPS77833DR in Tape & Reel format is optimized for automated assembly lines. TPS77733DR in Cut Tape & Digi-Reel® format is suitable for lower-volume or manual assembly scenarios.

Q: Do I need to update my bill of materials (BOM)? A: Either part number can be used interchangeably in your BOM. Verify with your procurement and manufacturing teams regarding packaging format preferences and supplier availability.
