Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS71812-33DRVR are determined by strict equivalence across the following critical parameters:

• Output voltage configuration (1.2V and 3.3V dual fixed outputs)
• Maximum output current rating (200mA per channel)
• Maximum input voltage specification (6.5V)
• Dropout voltage performance (0.4V @ 200mA)
• Package type and form factor (6-WSON 2x2 with exposed pad)
• Operating temperature range (-40°C to 125°C)
• Control and protection features (Enable control, Over Current, Over Temperature, UVLO protection)
• Compliance certifications (ROHS3, MSL 1)

The TPS71812-33DRVT is classified as a parametric equivalent substitute. Both parts share identical electrical specifications, output configurations, and package specifications. The difference between these part numbers relates to packaging format within the same product line.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS71812-33DRVR and TPS71812-33DRVT are active production parts from Texas Instruments with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts should be based on:

• Packaging format availability and procurement lead times
• Inventory levels at authorized distributors
• Project-specific supply chain requirements
• PCB assembly process compatibility with the specified package format

Both parts meet all regulatory and compliance requirements for applications requiring dual fixed output linear regulation at 1.2V and 3.3V with 200mA output capability.

Frequently Asked Questions (FAQ)

Q: Can TPS71812-33DRVT be used as a direct replacement for TPS71812-33DRVR?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage ratings, current ratings, and package specifications. The parts are functionally interchangeable in circuit design.

Q: What is the difference between TPS71812-33DRVR and TPS71812-33DRVT?
