TPS70938DBVR Equivalent & Substitute Parts

Part Overview

The TPS70938DBVR is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. It delivers a fixed positive output of 3.8V at 150mA in a surface-mount SOT-23-5 package. The device is designed for applications requiring low-dropout regulation with integrated protection features including over-current, over-temperature, reverse-current, and under-voltage lockout (UVLO) protection. The part is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1). Identifying equivalent substitute parts is necessary for supply chain continuity, design flexibility, and procurement optimization when the primary part number becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS70938DBVR are determined by strict equivalence across the following critical parameters:

• Output voltage configuration: Fixed positive 3.8V output
• Output current capability: 150mA
• Maximum input voltage rating: 30V
• Dropout voltage specification: 1.4V @ 150mA
• Package type: SOT-23-5 (SC-74A)
• Protection feature set: Over-current, over-temperature, reverse-current, and UVLO protection
• Operating temperature range: -40°C to 125°C
• Regulatory compliance: RoHS3 compliant
• Product status: Active

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. Variations in packaging designation (such as tape & reel versus alternative distribution formats) do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS70938DBVR and TPS70938DBVT are active production parts from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts is based on procurement availability and supply chain requirements rather than functional differences. Both parts carry RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution. The MSL 1 rating indicates unlimited shelf life under standard storage conditions, eliminating moisture-related constraints during component handling and assembly. Either part is suitable for direct substitution in applications currently specified for the TPS70938DBVR without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can TPS70938DBVT be used as a direct replacement for TPS70938DBVR?

A: Yes. Both parts are parametric equivalents with identical electrical characteristics, output specifications, protection features, and package configuration. No circuit modifications are required for substitution.

Q: Are there differences in package handling or storage between these parts?

Q: What determines whether a part qualifies as a substitute for the TPS70938DBVR?

A: A substitute must match all critical parameters: 3.8V fixed output, 150mA output current, 30V maximum input voltage, 1.4V dropout voltage at 150mA, SOT-23-5 package, identical protection features, -40°C to 125°C operating range, and active product status with RoHS3 compliance.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and regulatory classifications (ECCN: EAR99, HTSUS: 8542.39.0001).

Q: Can these parts be used interchangeably in PCB layouts?

A: Yes. Both parts use the same SOT-23-5 (SC-74A) package footprint, allowing direct PCB layout compatibility without modification.
