Substitute Part Grouping Explanation

Substitution for the TPS72301DBVT is determined by the following critical parameters: output configuration (negative), output type (adjustable), current capacity (200mA), voltage range (-1.2V to -10V), package type (SOT-23-5), and operating temperature range (-40°C to 125°C).

Substitute parts are grouped into two categories:

Parametric Equivalents maintain identical electrical specifications and negative output configuration. These parts are direct replacements with the same voltage range, current capacity, and dropout characteristics.

Functional Alternative (TPS73201DBVT) differs in output configuration (positive instead of negative) and is suitable only for applications where polarity inversion is acceptable or where positive regulation is required instead.

Engineering Selection Recommendations

For Direct Replacement (Negative Output Required):

TPS72301DBVR is the primary parametric equivalent with Active product status and identical electrical specifications. This part is recommended for new designs and production continuity due to its active status and full availability.

TPS72301QDBVRQ1 provides an automotive-qualified alternative (AEC-Q100) with identical electrical performance. This variant is suitable for automotive applications requiring qualification compliance and is supplied in Tape & Reel packaging format.

TPS72301DBVRG4 maintains full parametric equivalence but carries Discontinued at DiGi Electronics status, limiting its suitability for long-term production planning.

For Polarity-Inverted Applications (Positive Output):

TPS73201DBVT serves applications requiring positive adjustable regulation. This part offers higher output current (250mA versus 200mA) and superior dropout performance (0.15V @ 250mA versus 0.5V @ 200mA). Selection of this alternative requires circuit redesign to accommodate positive voltage output and is not a direct pin-for-pin replacement.

All recommended substitutes maintain ROHS3 compliance and identical operating temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can TPS72301DBVR be used as a direct replacement for TPS72301DBVT?

A: Yes. TPS72301DBVR is a parametric equivalent with identical output configuration (negative), current capacity (200mA), voltage range (-1.2V to -10V), dropout characteristics, and package type (SOT-23-5). The primary difference is product status: TPS72301DBVR is Active while TPS72301DBVT is Last Time Buy.

Q: What is the difference between TPS72301QDBVRQ1 and TPS72301DBVR?

A: Both parts are parametric equivalents with identical electrical specifications. TPS72301QDBVRQ1 includes automotive qualification (AEC-Q100) and is supplied in Tape & Reel packaging, while TPS72301DBVR is supplied in Cut Tape & Digi-Reel format. Selection depends on application requirements and packaging preferences.

Q: Why is TPS73201DBVT listed as a substitute if it has positive output instead of negative?

A: TPS73201DBVT is a functional alternative for applications where positive voltage regulation is acceptable or required. It is not a direct replacement due to inverted polarity. Circuit redesign is necessary for this substitution. This part offers higher current capacity (250mA) and better dropout performance.

Q: Is TPS72301DBVRG4 suitable for new production?

A: TPS72301DBVRG4 is not recommended for new production due to its Discontinued at DiGi Electronics status. TPS72301DBVR is the preferred active alternative for ongoing designs.

Q: Do all substitute parts maintain the same package footprint?

A: Yes. All listed substitutes use the SOT-23-5 package (SC-74A, SOT-753 case), ensuring identical PCB footprint compatibility. Packaging format (Cut Tape, Digi-Reel, or Tape & Reel) affects supply and handling but not physical dimensions.

Q: Are all substitutes RoHS compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance, matching the original TPS72301DBVT specification.
