Key Parameters

Substitute Part Grouping Explanation

Substitution of the REG102GA-5 is determined by the following critical parameters:

• Output voltage specification (5V fixed)
• Output current capability (minimum 250mA)
• Input voltage tolerance (maximum 10V or higher)
• Dropout voltage performance
• Surface mount packaging compatibility
• Regulatory compliance (RoHS3)
• Operating temperature range support

The TPS7A2550DRVR qualifies as a substitute based on matching output voltage (5V fixed), exceeding output current capability (300mA vs 250mA), supporting higher input voltage (18V vs 10V), and maintaining RoHS3 compliance. The substitute offers improved electrical performance characteristics including lower dropout voltage and quiescent current, with expanded operating temperature range (-40°C ~ 125°C).

Parameter Comparison

Engineering Selection Recommendations

The TPS7A2550DRVR is an active product from Texas Instruments and represents a viable substitute for the REG102GA-5. Both devices maintain ROHS3 compliance and are manufactured by the same supplier, ensuring regulatory consistency.

The primary consideration for substitution is package compatibility. The REG102GA-5 uses SOT-223-6 packaging, while the TPS7A2550DRVR uses 6-WDFN Exposed Pad packaging. PCB layout modifications are required to accommodate the different package footprint and pin configuration.

The TPS7A2550DRVR provides enhanced electrical performance with lower dropout voltage and improved quiescent current characteristics. The expanded input voltage rating (18V vs 10V) and extended operating temperature range (-40°C ~ 125°C vs -40°C ~ 85°C) offer additional design margin for applications with variable input conditions or thermal constraints.

Frequently Asked Questions (FAQ)

Q: Can the TPS7A2550DRVR directly replace the REG102GA-5 without PCB modifications?

A: No. The TPS7A2550DRVR uses 6-WDFN Exposed Pad packaging while the REG102GA-5 uses SOT-223-6 packaging. Different footprints and pin configurations require PCB layout redesign.

Q: What are the key electrical advantages of the TPS7A2550DRVR?

A: The substitute offers lower dropout voltage (0.21V vs 0.27V), higher output current capability (300mA vs 250mA), lower quiescent current (4.5µA vs 500µA), and higher maximum input voltage rating (18V vs 10V).

Q: Are both devices RoHS compliant?

A: Yes. Both the REG102GA-5 and TPS7A2550DRVR are ROHS3 compliant, ensuring regulatory consistency in applications requiring RoHS certification.

Q: Does the TPS7A2550DRVR support the same operating temperature range?

A: The TPS7A2550DRVR supports an extended operating temperature range of -40°C ~ 125°C compared to the REG102GA-5 range of -40°C ~ 85°C, providing additional thermal margin.

Q: What control features differ between these devices?

A: The REG102GA-5 includes Enable control. The TPS7A2550DRVR includes Enable and Power Good control features, offering additional monitoring capability.

Q: Is the TPS7A2550DRVR currently available?

A: Yes. The TPS7A2550DRVR is classified as Active product status with 3100 pieces in stock, ensuring ongoing availability compared to the REG102GA-5 Last Time Buy status.
