Substitute Part Grouping Explanation

Substitution for the REG102GA-5/2K5 is determined by the following critical electrical and mechanical parameters:

• Output voltage specification: 5V fixed
• Output current capability: 250mA minimum
• Input voltage tolerance: 10V maximum
• Dropout voltage performance: 0.27V @ 250mA
• Package type: SOT-223-6 surface mount
• Protection features: Over-current and over-temperature protection
• Control capability: Enable function
• Operating temperature range: -40°C to 85°C

The substitute part REG102GA-5 maintains identical electrical specifications and package configuration, differing only in product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The REG102GA-5 serves as the direct functional equivalent to the REG102GA-5/2K5. Both parts are manufactured by Texas Instruments with identical electrical performance specifications and SOT-223-6 package configuration. The primary distinction is product lifecycle status: REG102GA-5/2K5 is classified as Obsolete, while REG102GA-5 is designated Last Time Buy, indicating extended availability for procurement planning purposes.

Both parts maintain ROHS3 compliance and REACH unaffected status, supporting equivalent regulatory requirements for industrial and commercial applications. The electrical parameters—including 5V fixed output, 250mA current capacity, 0.27V dropout voltage, and integrated protection features—are identical across both variants, ensuring direct functional interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can REG102GA-5 directly replace REG102GA-5/2K5 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The REG102GA-5 maintains the same output voltage, current rating, dropout voltage, protection features, and SOT-223-6 package configuration. No circuit modifications are required.

Q: What is the difference between REG102GA-5/2K5 and REG102GA-5?

A: The parts are functionally equivalent. REG102GA-5/2K5 is Obsolete, while REG102GA-5 is Last Time Buy. The packaging format differs (REG102GA-5 is supplied in Tube packaging), but electrical specifications and pin configuration remain identical.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical RoHS3 compliance and REACH unaffected status. Regulatory requirements are equivalent for both variants.

Q: What parameters must remain constant when selecting a substitute?

A: Critical parameters for substitution include 5V fixed output voltage, 250mA output current, 10V maximum input voltage, 0.27V dropout voltage at 250mA, SOT-223-6 package type, and -40°C to 85°C operating temperature range. Any deviation from these specifications requires re-evaluation of circuit compatibility.

Q: Is the SOT-223-6 package critical for substitution?

A: Yes. The package type is a mandatory substitution criterion. The SOT-223-6 surface mount configuration defines the physical and electrical interface. Alternative packages require PCB layout modifications and are not considered direct substitutes.
