Engineering Selection Recommendations

Primary Recommendation: TPS79325DBVR This part is the direct successor to the TPS79325DBVREP. It maintains identical electrical specifications with extended operating temperature range (-40°C ~ 150°C versus -40°C ~ 125°C) and holds Active product status. It is available in Cut Tape and Digi-Reel packaging with 3300 units in stock.

Secondary Recommendation: TPS79325DBVRQ1 This automotive-qualified variant (AEC-Q100) provides the same electrical performance as the original part with Active status. It is suitable for applications requiring automotive-grade components and is available in Tape & Reel packaging.

Alternative for Extended Temperature: TPS79325DBVR When operating temperature range extension to 150°C is acceptable, TPS79325DBVR provides superior availability and active manufacturing status.

Alternative for Higher Current Capacity: RT9193-25GB When application requirements permit increased output current (300mA versus 200mA), the RT9193-25GB offers lower quiescent current (130 µA versus 220 µA), improved power efficiency, and significantly higher inventory availability (86100 units). This part maintains the same 2.5V output and SOT-23-5 package compatibility.

Avoid: TPS73025 Series (Last Time Buy Status) Parts TPS73025DBVT and TPS73025DBVTG4 are designated Last Time Buy, indicating discontinued production. While electrically compatible, these parts should not be selected for new designs or long-term supply requirements.

Frequently Asked Questions (FAQ)

Q: Can TPS79325DBVR directly replace TPS79325DBVREP? A: Yes. TPS79325DBVR is the active production equivalent with identical electrical specifications. The primary difference is extended operating temperature range (-40°C ~ 150°C) and active product status, making it the recommended direct replacement.

Q: What is the difference between TPS79325DBVR and TPS73025DBVR? A: Both deliver 2.5V at 200mA in SOT-23-5 packages. TPS79325DBVR has lower quiescent current (220 µA) and higher PSRR (70dB ~ 43dB across 100Hz ~ 100kHz). TPS73025DBVR has higher quiescent current (250 µA) but specifies dropout voltage (0.21V @ 200mA). TPS79325DBVR is the preferred choice for the original application.

Q: Is RT9193-25GB compatible with TPS79325DBVREP? A: RT9193-25GB is package-compatible (SOT-23-5) and provides the same 2.5V output. However, it delivers 300mA output current versus 200mA. It is suitable as a substitute when higher current capacity is acceptable or beneficial. Verify that the application circuit can tolerate the lower quiescent current (130 µA versus 220 µA).

Q: What is the difference between RT9193-25GB and RT9193-25GJ5? A: Both parts are electrically identical with 2.5V output and 300mA current capacity. RT9193-25GB uses standard SOT-23-5 packaging, while RT9193-25GJ5 uses TSOT-23-5 (thin variant). Select based on PCB layout requirements and available board space.

Q: Why should I avoid TPS73025 series parts? A: TPS73025DBVT and TPS73025DBVTG4 are designated Last Time Buy, indicating end-of-life status with no future production. These parts should not be selected for new designs or applications requiring long-term supply continuity.

Q: Is TPS79325DBVRQ1 suitable for non-automotive applications? A: Yes. TPS79325DBVRQ1 is automotive-qualified (AEC-Q100) but can be used in non-automotive applications. It provides identical electrical performance to TPS79325DBVR with Active product status and is available in Tape & Reel packaging.

Q: What packaging options are available for substitutes? A: TPS79325DBVR is available in Cut Tape and Digi-Reel. TPS73025DBVR is available in Tape & Reel. TPS73025DBVT and TPS73025DBVTG4 are available in Cut Tape and Digi-Reel. RT9193-25GB is available in Cut Tape and Digi-Reel. RT9193-25GJ5 uses TSOT-23-5 thin package. Select based on assembly process requirements.
