TPS7A0525PDBVR Equivalent & Substitute Parts

Part Overview

The TPS7A0525PDBVR is a linear voltage regulator IC manufactured by Texas Instruments, designed for positive fixed output applications. This device delivers 200mA output current at a fixed 2.5V output voltage and operates across an input voltage range up to 5.5V. The part is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Alternative equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity in applications requiring compatible linear regulation performance.

Substitute Part Grouping Explanation

Substitute parts for the TPS7A0525PDBVR are identified based on strict parametric equivalence within the linear voltage regulator category. The primary substitution criteria are:

Parametric Equivalence Requirements:

• Identical output voltage (2.5V fixed)
• Identical or higher output current rating (200mA minimum)
• Identical or lower dropout voltage performance
• Identical input voltage maximum rating (5.5V)
• Identical package type (SOT-23-5)
• Identical mounting type (Surface Mount)
• Active product status
• RoHS3 compliance

Substitute Classification:

Parametric Equivalent: TPS7A0525PDBVT matches all critical electrical and mechanical parameters identically to the main part, differing only in packaging format (Tape & Reel variant). This part is a direct functional equivalent suitable for direct substitution in all applications.

Manufacturer Recommended Substitute: RT9073-12GB is classified as a manufacturer-recommended alternative. This part operates at a different fixed output voltage (1.2V) and therefore is not a direct parametric equivalent. Substitution requires application-level verification that the 1.2V output voltage is compatible with the target circuit design.

Parameter Comparison

Engineering Selection Recommendations

TPS7A0525PDBVT (Parametric Equivalent): This part is suitable for direct substitution in all applications currently using TPS7A0525PDBVR. Both parts maintain identical electrical specifications, output voltage, current rating, and thermal operating range. Both are Active status products with RoHS3 compliance and MSL 1 rating. The only distinction is packaging format (Tape & Reel variant). Selection of this part requires no circuit redesign or application-level verification.

RT9073-12GB (Manufacturer Recommended): This part is classified as a manufacturer-recommended alternative but operates at a fundamentally different output voltage (1.2V versus 2.5V). Direct substitution is not applicable without circuit redesign. The RT9073-12GB is suitable only for applications requiring 1.2V regulation. Additional considerations include lower maximum operating temperature (85°C ambient versus 125°C junction temperature for TPS7A0525PDBVR) and higher moisture sensitivity level (MSL 3 versus MSL 1). Selection of this part requires application-level verification that the 1.2V output voltage is compatible with the target circuit design.

Frequently Asked Questions (FAQ)

Q: Can TPS7A0525PDBVT be used as a direct replacement for TPS7A0525PDBVR?

A: Yes. TPS7A0525PDBVT is a parametric equivalent with identical electrical specifications, output voltage (2.5V), output current (200mA), input voltage rating (5.5V), dropout voltage (0.308V @ 200mA), and operating temperature range (-40°C ~ 125°C). Both parts use the SOT-23-5 package. No circuit modifications are required.

Q: Can RT9073-12GB replace TPS7A0525PDBVR?

A: No, not as a direct substitution. RT9073-12GB operates at 1.2V fixed output voltage, whereas TPS7A0525PDBVR operates at 2.5V. These are different voltage regulation levels. RT9073-12GB is suitable only for applications specifically requiring 1.2V regulation. Circuit redesign and application-level verification are required before substitution.

Q: What are the key differences between TPS7A0525PDBVR and RT9073-12GB?

A: The primary differences are: (1) Output voltage: TPS7A0525PDBVR is 2.5V fixed; RT9073-12GB is 1.2V fixed. (2) Dropout voltage: TPS7A0525PDBVR has 0.308V @ 200mA; RT9073-12GB has 1.2V @ 250mA. (3) Operating temperature: TPS7A0525PDBVR operates to 125°C (junction); RT9073-12GB operates to 85°C (ambient). (4) Moisture sensitivity: TPS7A0525PDBVR is MSL 1; RT9073-12GB is MSL 3. (5) PSRR: RT9073-12GB has superior PSRR (75dB at 1kHz versus 40dB at 1kHz~1MHz).

Q: Are all substitute parts available in the same package?

A: Yes. TPS7A0525PDBVR, TPS7A0525PDBVT, and RT9073-12GB all use the SOT-23-5 package (SC-74A, SOT-753 case). Pin-to-pin compatibility is maintained across all three parts.

Q: What is the difference between TPS7A0525PDBVR and TPS7A0525PDBVT packaging?

A: TPS7A0525PDBVR is supplied in Tape & Reel (TR) format. TPS7A0525PDBVT is also supplied in Tape & Reel (TR) format. Both are identical in electrical performance and package type; the designation difference reflects manufacturing lot or supply chain variant coding.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TPS7A0525PDBVR, TPS7A0525PDBVT, and RT9073-12GB are all RoHS3 compliant and REACH unaffected.
