Engineering Selection Recommendations

Direct Parametric Equivalents:

TPS73601DBVT and TPS73601QDBVRQ1 are parametric equivalents of TPS73601DBVR, offering identical electrical specifications and package configuration. TPS73601QDBVRQ1 includes automotive-grade qualification (AEC-Q100) and is suitable for applications requiring automotive compliance. These parts maintain full functional compatibility with existing circuit designs.

Functional Alternatives with Parameter Variations:

LDK130M-R (STMicroelectronics) provides adjustable output regulation in SOT-23-5 package with automotive qualification (AEC-Q100). Output current is reduced to 300mA, and dropout voltage increases to 0.4V @ 300mA. This part is suitable for applications with lower current requirements and extended temperature range support.

MIC5219YM5-TR (Microchip Technology) offers 500mA output current in SOT-23-5 package with superior quiescent current (8 µA) and higher input voltage rating (12V). Dropout voltage is 0.6V @ 500mA. This part is applicable for higher current applications with lower power consumption requirements.

RT9043GB and RT9053AGB (Richtek USA Inc.) provide 400mA output current in SOT-23-5 package with reduced quiescent current (50 µA) and improved dropout voltage (0.35V @ 400mA). Operating temperature range is limited to -40°C ~ 85°C. These parts are suitable for applications prioritizing low quiescent current performance.

RT9080-12GJ5 (Richtek USA Inc.) is a fixed-output regulator (1.2V) with 600mA output current and ultra-low quiescent current (4 µA). This part is not suitable for adjustable output applications and requires fixed voltage output compatibility.

BD00IC0WHFV-GTR (Rohm Semiconductor) delivers 1A output current in 6-HVSOF package with adjustable output configuration. Operating temperature range is -25°C ~ 85°C. Package change from SOT-23-5 to 6-HVSOF requires PCB layout modification and is suitable only for applications with higher current demands and package compatibility.

Compliance and Availability:

All listed parts maintain ROHS3 compliance and Active product status. Parts with MSL Level 1 (TPS73601DBVR, TPS73601DBVT, TPS73601QDBVRQ1, LDK130M-R, MIC5219YM5-TR, BD00IC0WHFV-GTR) offer unlimited moisture sensitivity handling.

Frequently Asked Questions (FAQ)

Q: Can TPS73601DBVT be used as a direct replacement for TPS73601DBVR?

A: Yes. TPS73601DBVT is a parametric equivalent with identical electrical specifications, package configuration, and performance characteristics. No circuit modifications are required.

Q: What is the difference between TPS73601DBVR and TPS73601QDBVRQ1?

A: Both parts share identical electrical specifications and package type. TPS73601QDBVRQ1 includes automotive-grade qualification (AEC-Q100) and is designated for automotive applications. Selection depends on application requirements for automotive compliance.

Q: Can LDK130M-R replace TPS73601DBVR in all applications?

A: LDK130M-R is functionally compatible for applications with output current requirements of 300mA or less. The reduced current rating (300mA vs. 400mA) and increased dropout voltage (0.4V vs. 0.2V) must be evaluated against circuit requirements. LDK130M-R offers automotive qualification (AEC-Q100) and lower quiescent current (60 µA).

Q: What are the advantages of MIC5219YM5-TR over TPS73601DBVR?

A: MIC5219YM5-TR provides higher output current (500mA), significantly lower quiescent current (8 µA vs. 550 µA), and higher input voltage rating (12V vs. 5.5V). Disadvantages include higher dropout voltage (0.6V vs. 0.2V) and higher input voltage maximum rating may not be compatible with 5.5V input-limited applications.

Q: Why is RT9080-12GJ5 not recommended as a substitute?

A: RT9080-12GJ5 is a fixed-output regulator with 1.2V output voltage. TPS73601DBVR is an adjustable-output regulator. These parts are functionally incompatible unless the application requires fixed 1.2V output exclusively.

Q: Can BD00IC0WHFV-GTR be used instead of TPS73601DBVR?

A: BD00IC0WHFV-GTR offers higher output current (1A) and adjustable output configuration but uses a different package (6-HVSOF vs. SOT-23-5). Package change requires PCB layout redesign. Operating temperature range is reduced to -25°C ~ 85°C. Substitution is possible only if PCB layout modification is acceptable and temperature range is compatible.

Q: What does MSL Level 1 vs. MSL Level 3 mean for component handling?

A: MSL Level 1 (Unlimited) allows indefinite storage without moisture absorption concerns. MSL Level 3 (168 Hours) requires controlled storage conditions and limits exposure to ambient humidity to 168 hours maximum before reflow soldering. Parts with MSL Level 3 require more stringent handling procedures.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance status, meeting environmental and hazardous substance restrictions.

Q: Which substitute offers the lowest quiescent current?

A: RT9080-12GJ5 provides the lowest quiescent current at 4 µA. However, this part is a fixed-output regulator and not suitable for adjustable output applications. Among adjustable-output alternatives, MIC5219YM5-TR offers 8 µA quiescent current.
