Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS76850MPWPREP is determined by strict equivalence across the following critical parameters:

• Output voltage configuration (5V fixed positive output)
• Output current rating (1A minimum)
• Maximum input voltage tolerance (10V)
• Voltage dropout specification (0.38V @ 1A)
• Quiescent current (125 µA)
• PSRR performance (60dB @ 1kHz)
• Control features (Enable and Power Good functions)
• Protection features (Over Current, Over Temperature, Reverse Polarity)
• Package type (20-PowerTSSOP)
• RoHS compliance (ROHS3)

The TPS76850QPWPRQ1 qualifies as a manufacturer-recommended substitute based on identical electrical specifications and package configuration. Differences in product status, operating temperature range, packaging format, and automotive qualification do not affect functional equivalence for standard applications.

Parameter Comparison

Engineering Selection Recommendations

The TPS76850QPWPRQ1 is the manufacturer-recommended substitute for the TPS76850MPWPREP. Both devices share identical electrical performance specifications and package configuration, ensuring direct functional compatibility.

Selection between these parts should be based on application requirements and supply chain considerations:

• For applications requiring extended low-temperature operation below -40°C, the TPS76850MPWPREP maintains specifications to -55°C.
• For automotive applications or designs requiring AEC-Q100 qualification, the TPS76850QPWPRQ1 provides automotive-grade certification.
• The TPS76850QPWPREP is currently in active production status, providing superior long-term availability compared to the Last Time Buy status of the TPS76850MPWPREP.
• Packaging format differences (Tape & Reel versus Cut Tape & Digi-Reel) affect procurement and handling but do not impact electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the TPS76850QPWPRQ1 directly replace the TPS76850MPWPREP in existing designs?

A: Yes. Both devices are electrically identical across all critical parameters including output voltage, current rating, dropout voltage, quiescent current, PSRR, control features, and protection features. The 20-PowerTSSOP package is identical, enabling direct PCB-level substitution.

Q: What is the significance of the operating temperature range difference?

A: The TPS76850MPWPREP operates from -55°C to 125°C, while the TPS76850QPWPRQ1 operates from -40°C to 125°C. For applications requiring operation below -40°C, the TPS76850MPWPREP is required. For standard industrial and automotive applications operating above -40°C, both parts are equivalent.

Q: Why does the TPS76850QPWPRQ1 have automotive qualification while the TPS76850MPWPREP does not?

A: The TPS76850QPWPRQ1 carries AEC-Q100 automotive qualification, indicating compliance with automotive reliability and quality standards. The TPS76850MPWPREP is a standard industrial-grade device. This distinction affects suitability for automotive applications but does not impact electrical performance in non-automotive environments.

Q: Are there packaging considerations when switching between these parts?

A: The TPS76850MPWPREP is supplied in Tape & Reel (TR) format, while the TPS76850QPWPRQ1 is available in Cut Tape (CT) and Digi-Reel® formats. Both formats contain identical components in the same 20-PowerTSSOP package. Packaging format selection depends on assembly equipment and procurement volume requirements.

Q: What is the impact of different Moisture Sensitivity Levels (MSL)?

A: The TPS76850MPWPREP has MSL 2 (1 Year shelf life), while the TPS76850QPWPRQ1 has MSL 3 (168 Hours shelf life). MSL affects storage and handling requirements. Higher MSL ratings require more stringent moisture control during storage and assembly. For applications with standard handling and assembly processes, both parts are compatible.

Q: Is the TPS76850QPWPRQ1 recommended for new designs?

A: The TPS76850QPWPRQ1 is in active production status, making it suitable for new designs requiring long-term component availability. The TPS76850MPWPREP is in Last Time Buy status, indicating limited future availability. For new designs, the TPS76850QPWPRQ1 is the preferred choice.
