TPS61097-33DBVR Equivalent & Substitute Parts

Part Overview

The TPS61097-33DBVR is a boost switching regulator IC manufactured by Texas Instruments, designed for step-up voltage conversion with a fixed 3.3V output. This device operates across an input voltage range of 0.9V to 5.5V and delivers 200mA output current in a compact SC-74A (SOT-753) surface mount package. The part is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent substitute parts is necessary for ongoing production support, legacy system maintenance, and design continuity where this topology and output specification remain functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS61097-33DBVR are qualified based on the following electrical and mechanical parameters:

• Topology & Function: Boost switching regulator with step-up conversion capability
• Output Voltage: Fixed 3.3V output
• Input Voltage Range: 0.9V to 5.5V minimum and maximum
• Output Current Capability: Equal to or greater than 200mA
• Package Compatibility: SC-74A (SOT-753) surface mount package
• Synchronous Rectifier: Integrated synchronous rectification
• Operating Temperature Range: -40°C to 85°C
• Regulatory Compliance: ROHS3 compliant, REACH unaffected

The substitute parts identified (XC9140A331MR-G and XC9140C331MR-G from Torex Semiconductor Ltd) meet all these criteria. Both devices provide enhanced output current capability (295mA) compared to the original specification, ensuring functional compatibility and improved performance headroom in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Both XC9140A331MR-G and XC9140C331MR-G are active, production-supported alternatives to the end-of-life TPS61097-33DBVR. Selection between these two Torex devices should be based on availability and supply chain considerations, as they are electrically and mechanically identical. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component. The increased output current rating (295mA versus 200mA) provides additional design margin without requiring circuit modifications. Direct pin-compatible replacement is supported by the identical SC-74A package footprint.

Frequently Asked Questions (FAQ)

Q: Are the XC9140 series parts pin-compatible with the TPS61097-33DBVR?

A: Yes. Both substitute parts use the SC-74A (SOT-753) package with identical pinout and electrical interface, enabling direct board-level replacement without layout modifications.

Q: What is the difference between XC9140A331MR-G and XC9140C331MR-G?

A: Both parts are electrically and mechanically identical. The difference lies in manufacturing date code or internal process variation designated by the "A" or "C" suffix. Selection can be based on availability and supply chain preference.

Q: Can the higher output current rating (295mA) of the substitute parts cause issues in existing designs?

A: No. The increased current capability of the XC9140 series is a performance enhancement that does not negatively impact designs rated for 200mA. The fixed 3.3V output voltage and input voltage range remain identical, ensuring functional compatibility.

Q: Are there any package or thermal considerations when substituting these parts?

A: Both substitute parts use the same SC-74A (SOT-753) surface mount package as the original TPS61097-33DBVR. Thermal performance and board layout considerations remain unchanged.

Q: What is the inventory status of these substitute parts?

A: XC9140A331MR-G has 2,459 pieces in stock, and XC9140C331MR-G has 1,102 pieces in stock, both available as new original components in Tape & Reel packaging.
