Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS767D301MPWPREP is determined by strict alignment across the following critical parameters:

Electrical Compatibility Requirements:

• Identical output configuration (Positive)
• Matching number of regulators (2)
• Identical maximum input voltage (10V)
• Overlapping output voltage range (1.5V to 5.5V)
• Equivalent current output capacity (1A)
• Matching voltage dropout specification (0.58V @ 1A)
• Identical quiescent current (125 µA)
• Equivalent PSRR performance (60dB at 1kHz)
• Identical control features (Enable, Reset)
• Identical protection features (Over Current, Over Temperature, Reverse Polarity)

Mechanical & Packaging Requirements:

• Identical package type (28-PowerTSSOP)
• Identical mounting type (Surface Mount)
• Identical supplier device package (28-HTSSOP)

Compliance Requirements:

• ROHS3 compliance maintained
• Identical ECCN and HTSUS classifications

The TPS767D301QPWPRQ1 meets all substitution criteria as a direct equivalent, with the distinction of Active product status and automotive-grade qualification.

Parameter Comparison

Engineering Selection Recommendations

The TPS767D301QPWPRQ1 is a direct functional equivalent to the TPS767D301MPWPREP across all critical electrical and mechanical parameters. The substitute part offers the advantage of Active product status, ensuring continued availability and supply chain stability.

The TPS767D301QPWPRQ1 carries automotive-grade qualification (AEC-Q100) and is suitable for applications requiring automotive-level reliability standards. The operating temperature range of the substitute is -40°C to 125°C, which covers the lower end of the main part's range (-55°C to 125°C). Applications requiring operation below -40°C must retain the original TPS767D301MPWPREP specification.

Both parts maintain ROHS3 compliance and identical electrical performance characteristics. The MSL rating difference (2 versus 3) reflects standard moisture sensitivity classifications and does not affect functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the TPS767D301QPWPRQ1 replace the TPS767D301MPWPREP in all applications?

A: The TPS767D301QPWPRQ1 is electrically and mechanically equivalent across all specified parameters. The primary consideration is operating temperature: the substitute operates from -40°C to 125°C, while the original operates from -55°C to 125°C. Applications requiring operation below -40°C must use the original part.

Q: What is the significance of the automotive-grade qualification on the substitute part?

A: The TPS767D301QPWPRQ1 carries AEC-Q100 qualification, indicating compliance with automotive industry reliability and quality standards. This qualification is not present on the original part. For non-automotive applications, this distinction does not affect functional performance.

Q: Are the package dimensions identical between the two parts?

A: Yes. Both parts use the 28-PowerTSSOP package with identical dimensions (0.173", 4.40mm Width). PCB layout and footprints are directly compatible.

Q: What is the difference in MSL ratings between these parts?

A: The TPS767D301MPWPREP has MSL 2 (1 Year shelf life), while the TPS767D301QPWPRQ1 has MSL 3 (168 Hours shelf life). This reflects standard moisture sensitivity classifications and does not affect electrical performance or functional equivalence.

Q: Are both parts RoHS compliant?

A: Yes. Both the TPS767D301MPWPREP and TPS767D301QPWPRQ1 are ROHS3 compliant.

Q: Why is the original part marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of the TPS767D301MPWPREP. The TPS767D301QPWPRQ1 remains in Active production status, making it the recommended choice for new designs and ongoing supply requirements.
