Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS76030DBVT are identified based on the following critical parameters that determine functional equivalence:

Primary Equivalence Criteria:

• Output voltage configuration: Positive fixed 3V output
• Package compatibility: SOT-23-5 (SC-74A, SOT-753)
• Mounting type: Surface Mount
• Input voltage rating: Maximum 16V
• Operating temperature range: -40°C ~ 125°C
• Protection features: Over Current, Over Temperature, Reverse Polarity

Substitution Categories:

Parametric Equivalent: Parts with identical electrical specifications and package form factor, allowing direct replacement without circuit modification.

Manufacturer Recommended: Parts with compatible output voltage and package but different current ratings or dropout characteristics, suitable for applications where the higher current capacity provides design margin or where dropout voltage differences are acceptable within the application circuit.

Parameter Comparison

Engineering Selection Recommendations

TPS76030DBVR (Texas Instruments): This part is a parametric equivalent to the TPS76030DBVT with identical electrical specifications and package configuration. Both devices are Active status products from the same manufacturer with ROHS3 compliance. Selection between these two variants is based on packaging format (Tape & Reel availability) and inventory considerations.

MIC5225-3.0YM5-TR (Microchip Technology): This part provides a 3V fixed output in the same SOT-23-5 package with expanded current capacity of 150mA compared to the 50mA rating of the TPS76030DBVT. The device maintains compatibility with the 16V maximum input voltage and -40°C ~ 125°C operating temperature range. The higher dropout voltage of 0.45V @ 150mA should be evaluated against application circuit requirements. This part is suitable for applications requiring higher current delivery or where design margin is prioritized. Both devices are Active status with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can TPS76030DBVR be used as a direct replacement for TPS76030DBVT?

A: Yes. Both parts are identical in electrical specifications, output voltage (3V fixed), current rating (50mA), dropout voltage (0.18V @ 50mA), and package configuration (SOT-23-5). The difference is in packaging format and supplier inventory. Direct PCB substitution is possible without circuit modification.

Q: Is MIC5225-3.0YM5-TR compatible with TPS76030DBVT applications?

A: Compatibility depends on application current requirements. The MIC5225-3.0YM5-TR provides 150mA output capacity versus 50mA for the TPS76030DBVT, with identical 3V fixed output and SOT-23-5 package. The higher dropout voltage (0.45V @ 150mA versus 0.18V @ 50mA) must be evaluated in the application circuit to ensure adequate headroom between input and output voltages. Pin-compatible package allows direct PCB substitution.

Q: What are the key parameters that determine substitution eligibility?

A: Critical parameters are output voltage (3V fixed), package type (SOT-23-5), maximum input voltage (16V), operating temperature range (-40°C ~ 125°C), and mounting type (Surface Mount). Current output rating and dropout voltage are secondary parameters that determine application suitability within the substitution category.

Q: Are all substitute parts RoHS compliant?

A: Yes. TPS76030DBVR and MIC5225-3.0YM5-TR are both ROHS3 compliant, matching the compliance status of the TPS76030DBVT.

Q: What is the difference between TPS76030DBVT and TPS76030DBVR?

A: Both parts are electrically identical with the same output voltage, current rating, and performance specifications. The designation difference reflects packaging format and supplier tape configuration. Both are Active status products suitable for equivalent applications.
