Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for linear voltage regulator ICs is determined by compatibility across the following critical parameters:

Package Compatibility: Both the main part and substitute must share identical or functionally equivalent surface mount packages. The TPS7A2015PDBVR and RT9073-12GB both utilize SOT-23-5 packaging (SC-74A, SOT-753), enabling direct physical interchange on printed circuit boards.

Output Configuration: Both devices deliver positive fixed output voltage regulation with a single output channel, satisfying identical circuit topology requirements.

Electrical Operating Range: The substitute part must operate within the input voltage range and deliver sufficient output current for the intended application. The RT9073-12GB accepts maximum input voltage of 5.5V (within the 6V specification of the main part) and delivers 250mA output current (within the 300mA requirement).

Output Voltage Specification: The RT9073-12GB provides 1.2V fixed output, which differs from the TPS7A2015PDBVR's 1.5V output. Substitution is valid only for applications specifically designed for 1.2V output operation.

Temperature Operating Range: The RT9073-12GB operates from -40°C to 85°C (TA), which is narrower than the TPS7A2015PDBVR's -40°C to 125°C (TJ) range. Substitution is valid for applications within the -40°C to 85°C window.

Control and Protection Features: The RT9073-12GB includes Enable control and Over Current/Over Temperature protection. The TPS7A2015PDBVR additionally includes Soft Start and Under Voltage Lockout (UVLO) features. Applications requiring these additional features cannot use the RT9073-12GB as a substitute.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The TPS7A2015PDBVR remains the primary selection for applications requiring 1.5V fixed output regulation with 300mA output current capacity. This device is in active production status with substantial inventory availability (3300 units in stock). The extended operating temperature range (-40°C to 125°C junction temperature) and comprehensive protection feature set (including Soft Start and UVLO) support demanding industrial and automotive applications.

Substitute Part Applicability: The RT9073-12GB is applicable as a substitute only for applications meeting all of the following criteria:

• Output voltage requirement is 1.2V fixed (not 1.5V)
• Maximum output current requirement does not exceed 250mA
• Operating temperature range does not exceed -40°C to 85°C
• Soft Start and Under Voltage Lockout (UVLO) features are not required
• Application does not require RoHS3 compliance (if RoHS3 compliance is mandatory, the RT9073-12GB satisfies this requirement; the TPS7A2015PDBVR does not)

Compliance Considerations: The RT9073-12GB carries ROHS3 Compliant certification and REACH Unaffected status. The TPS7A2015PDBVR RoHS status is listed as Not applicable. Both devices carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Moisture Handling: The TPS7A2015PDBVR carries MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage and handling. The RT9073-12GB carries MSL 3 (168 Hours) rating, requiring controlled storage conditions and limiting shelf life to 168 hours at specified humidity levels after package opening.

Frequently Asked Questions (FAQ)

Q: Can the RT9073-12GB directly replace the TPS7A2015PDBVR in an existing circuit?

A: Direct physical replacement is possible due to identical SOT-23-5 packaging. However, electrical compatibility depends on application-specific requirements. The RT9073-12GB provides 1.2V output (not 1.5V) and 250mA maximum current (not 300mA). Substitution is valid only if the circuit is designed for 1.2V operation and does not exceed 250mA current draw. Additionally, applications requiring Soft Start or UVLO functionality cannot use the RT9073-12GB.

Q: What are the key differences in dropout voltage between these devices?

A: The TPS7A2015PDBVR exhibits 0.205V maximum dropout at 300mA output current. The RT9073-12GB exhibits 1.2V maximum dropout at 250mA output current. This significant difference affects minimum input voltage requirements and power dissipation characteristics. Applications with tight input voltage margins or high current demands require the superior dropout performance of the TPS7A2015PDBVR.

Q: Are there temperature range limitations when using the RT9073-12GB as a substitute?

A: Yes. The TPS7A2015PDBVR operates from -40°C to 125°C (junction temperature). The RT9073-12GB operates from -40°C to 85°C (ambient temperature). Applications requiring operation above 85°C ambient temperature cannot use the RT9073-12GB. The narrower temperature range of the RT9073-12GB may also affect thermal margin calculations in high-temperature environments.

Q: What protection features are lost when substituting with the RT9073-12GB?

A: The TPS7A2015PDBVR includes Soft Start and Under Voltage Lockout (UVLO) protection features. The RT9073-12GB includes only Enable control and basic Over Current/Over Temperature protection. Applications requiring controlled power-up sequencing (Soft Start) or input voltage monitoring (UVLO) cannot use the RT9073-12GB as a substitute.

Q: How do quiescent current specifications compare?

A: The TPS7A2015PDBVR draws 15µA quiescent current. The RT9073-12GB draws 3µA quiescent current. The lower quiescent current of the RT9073-12GB provides reduced standby power consumption in battery-powered applications. This difference becomes significant in applications with extended idle periods or strict power budget constraints.

Q: Are there packaging or handling differences between these devices?

A: Both devices use identical SOT-23-5 (SC-74A, SOT-753) surface mount packages. However, moisture sensitivity differs. The TPS7A2015PDBVR carries MSL 1 (Unlimited) rating with no moisture constraints. The RT9073-12GB carries MSL 3 (168 Hours) rating, requiring controlled humidity storage and limiting shelf life after package opening. This affects procurement, storage, and handling procedures.

Q: What is the significance of the PSRR (Power Supply Rejection Ratio) difference?

A: The TPS7A2015PDBVR specifies PSRR of 65dB at 100Hz declining to 40dB at 1MHz. The RT9073-12GB specifies PSRR of 75dB at 1kHz. The TPS7A2015PDBVR provides superior low-frequency noise rejection (65dB vs. unspecified at 100Hz), while the RT9073-12GB provides superior mid-frequency performance (75dB at 1kHz). Applications sensitive to specific frequency bands require evaluation of these characteristics.

Q: Can the RT9073-12GB be used in applications requiring RoHS3 compliance?

A: Yes. The RT9073-12GB carries ROHS3 Compliant certification. The TPS7A2015PDBVR RoHS status is listed as Not applicable. If RoHS3 compliance is a mandatory requirement, the RT9073-12GB satisfies this requirement while the TPS7A2015PDBVR does not.
