TPS77033DBVRG4 Equivalent & Substitute Parts

Part Overview

The TPS77033DBVRG4 is a linear voltage regulator IC from Texas Instruments designed for positive fixed 3.3V output at 50mA in a SOT-23-5 surface mount package. This part is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design support and procurement. The device provides regulated power with integrated protection features including over-current, over-temperature, and reverse polarity protection, suitable for low-power applications requiring stable 3.3V rails.

Substitute Part Grouping Explanation

Substitute parts for the TPS77033DBVRG4 are qualified based on strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

• Output voltage: 3.3V fixed
• Output current capability: 50mA
• Maximum input voltage: 10V
• Voltage dropout: 0.1V @ 50mA
• Package type: SOT-23-5 (SC-74A)
• Operating temperature range: -40°C to 125°C
• Protection features: Over Current, Over Temperature, Reverse Polarity
• Control features: Enable function

The TPS77033DBVRG4 is functionally equivalent to TPS77033DBVR and TPS77033DBVT. These parts share identical electrical specifications and packaging, with differences limited to product status and packaging format (Digi-Reel vs. Cut Tape).

Parameter Comparison

Engineering Selection Recommendations

TPS77033DBVR is the primary substitute for TPS77033DBVRG4. This part maintains active product status with Texas Instruments and offers the highest inventory availability (6400 pcs). All electrical and mechanical parameters are identical to the original part. The packaging format flexibility (Cut Tape and Digi-Reel options) provides procurement flexibility for both prototype and production volumes.

TPS77033DBVT is a secondary substitute option. While electrically equivalent, this part carries a Last Time Buy status, indicating limited future availability. Selection of this part should be based on immediate procurement needs only, as long-term supply cannot be assured.

Both substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original TPS77033DBVRG4.

Frequently Asked Questions (FAQ)

Q: Can TPS77033DBVR directly replace TPS77033DBVRG4 in production?

A: Yes. Both parts are electrically and mechanically identical. The TPS77033DBVR operates at the same output voltage (3.3V), current rating (50mA), dropout voltage (0.1V @ 50mA), and uses the same SOT-23-5 package. No circuit modifications are required.

Q: What is the difference between TPS77033DBVRG4 and TPS77033DBVR?

A: The primary difference is product status and packaging format. TPS77033DBVRG4 is discontinued at DiGi Electronics and supplied in Digi-Reel format. TPS77033DBVR is active and available in both Cut Tape and Digi-Reel formats. All electrical specifications are identical.

Q: Why is TPS77033DBVT marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has announced end-of-life for this specific part number variant. While currently available, future procurement cannot be guaranteed. For new designs or long-term production, TPS77033DBVR is the recommended choice.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the SOT-23-5 package with identical pin assignments and electrical characteristics. PCB layout and schematic connections require no modification when substituting between these parts.

Q: What compliance certifications apply to these substitute parts?

A: All three parts are ROHS3 compliant and REACH unaffected. Moisture Sensitivity Level is 1 (Unlimited) for all variants, indicating no special moisture handling requirements during storage or assembly.

Q: Can I use TPS77033DBVT for new production designs?

A: TPS77033DBVT is not recommended for new production designs due to Last Time Buy status. TPS77033DBVR should be selected for designs requiring long-term supply assurance and production continuity.
