Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS61097-33DBVT are qualified based on the following critical parameters:

• Fixed output voltage of 3.3V
• Input voltage range of 0.9V to 5.5V
• Boost (step-up) topology with positive output configuration
• Single output configuration
• Surface mount package compatibility (SC-74A, SOT-753)
• Synchronous rectifier architecture
• Operating temperature range of -40°C to 85°C
• RoHS3 compliance and MSL 1 rating

The substitute parts identified—XC9140A331MR-G and XC9140C331MR-G from Torex Semiconductor Ltd—meet all these core electrical and mechanical requirements. Both devices maintain identical input/output voltage specifications, package form factor, and environmental operating conditions. The primary distinction between the main part and substitutes is the increased output current capacity (295mA versus 200mA), which represents a functional enhancement rather than a limitation.

Parameter Comparison

Engineering Selection Recommendations

The TPS61097-33DBVT is designated as "Not For New Designs," indicating that Texas Instruments no longer recommends this part for new product development. The Torex Semiconductor XC9140A331MR-G and XC9140C331MR-G represent active alternatives that maintain full electrical and mechanical compatibility while offering enhanced current capacity.

Both substitute parts carry Active product status, ensuring long-term availability and continued manufacturer support. All three devices maintain identical RoHS3 compliance and MSL 1 ratings, confirming equivalent environmental and regulatory standing. The substitutes are suitable for direct replacement in existing designs and for new implementations requiring 3.3V boost regulation within the specified input voltage and current parameters.

Frequently Asked Questions (FAQ)

Q: Can XC9140A331MR-G and XC9140C331MR-G be used as direct replacements for TPS61097-33DBVT?

A: Yes. Both Torex devices maintain identical output voltage (3.3V), input voltage range (0.9V to 5.5V), package form factor (SC-74A, SOT-753), operating temperature range (-40°C to 85°C), and synchronous rectifier architecture. The increased output current capacity (295mA versus 200mA) represents a functional enhancement compatible with existing circuit designs.

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

A: Both parts are functionally identical in electrical specifications and package configuration. The designation difference (A versus C) reflects internal manufacturing or qualification variants from Torex Semiconductor Ltd. Both are Active products with equivalent availability and compliance status.

Q: Why is the TPS61097-33DBVT marked "Not For New Designs"?

A: This designation indicates that Texas Instruments has discontinued active promotion and development support for this part. Existing inventory remains available, but new designs should utilize active alternatives such as the Torex XC9140 series to ensure long-term supply chain stability and manufacturer support.

Q: Are there any package compatibility concerns when substituting these parts?

A: No. All three devices use the SC-74A SOT-753 package with identical pinout and mechanical dimensions, enabling direct PCB-level substitution without layout modifications.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. XC9140A331MR-G and XC9140C331MR-G are both ROHS3 compliant with MSL 1 rating, matching the environmental and regulatory specifications of the TPS61097-33DBVT.
