TPS76801MPWPREP Equivalent & Substitute Parts

Part Overview

The TPS76801MPWPREP is a linear voltage regulator IC from Texas Instruments designed for positive adjustable output applications. It delivers 1A output current with adjustable voltage range from 1.2V to 5.5V, suitable for power management in embedded systems and industrial applications. The device features integrated protection mechanisms including over-current, over-temperature, and reverse polarity protection, along with enable and power good control features.

The TPS76801MPWPREP is classified as Last Time Buy, indicating production discontinuation. Identifying equivalent substitute parts is necessary to ensure design continuity and maintain supply chain reliability for ongoing production and maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS76801MPWPREP is determined by strict alignment of the following critical parameters:

Output voltage range (1.2V to 5.5V adjustable), maximum input voltage (10V), output current capability (1A), quiescent current (125 µA), PSRR performance (60dB at 1kHz), control features (Enable and Power Good), protection mechanisms (Over Current, Over Temperature, Reverse Polarity), and physical package format (20-PowerTSSOP).

The TPS76801QPWPRQ1 meets all electrical and mechanical substitution criteria. This part maintains identical functional specifications while differing in product status (Active versus Last Time Buy), operating temperature range, packaging format (Cut Tape & Digi-Reel versus Tape & Reel), and automotive qualification level.

Parameter Comparison

Engineering Selection Recommendations

The TPS76801QPWPRQ1 is the manufacturer-recommended substitute for the TPS76801MPWPREP. Both parts share identical electrical specifications and package format, ensuring direct functional compatibility in circuit designs.

The TPS76801QPWPREP maintains Active product status, providing long-term availability and supply chain stability compared to the Last Time Buy status of the original part. The substitute carries AEC-Q100 automotive qualification, indicating compliance with automotive reliability and quality standards. This qualification extends applicability to automotive and mission-critical applications where enhanced reliability documentation is required.

The operating temperature range of the substitute (-40°C to 125°C) is narrower than the original part (-55°C to 125°C). Applications requiring operation below -40°C must retain the TPS76801MPWPREP or identify alternative solutions. For standard industrial and commercial temperature ranges, the substitute provides equivalent thermal performance.

Frequently Asked Questions (FAQ)

Q: Can the TPS76801QPWPRQ1 replace the TPS76801MPWPREP in existing designs?

A: Yes. Both parts deliver identical output voltage range (1.2V to 5.5V), output current (1A), quiescent current (125 µA), PSRR (60dB at 1kHz), control features (Enable and Power Good), protection mechanisms (Over Current, Over Temperature, Reverse Polarity), and package format (20-PowerTSSOP). Pin-for-pin compatibility is maintained. Design verification is required only if the application operates below -40°C, where the substitute's temperature range does not extend.

Q: What are the key differences between these parts?

A: The primary differences are product status (Last Time Buy versus Active), operating temperature range (-55°C to 125°C versus -40°C to 125°C), packaging format (Tape & Reel versus Cut Tape & Digi-Reel), and automotive qualification (standard versus AEC-Q100). Electrical performance and package dimensions are identical.

Q: Is the automotive qualification of the substitute relevant for non-automotive applications?

A: AEC-Q100 qualification indicates enhanced reliability testing and quality assurance. For non-automotive applications, this qualification provides additional confidence in component reliability but is not a functional requirement. Selection should be based on availability, temperature range requirements, and supply chain considerations.

Q: Are there packaging implications when switching from TPS76801MPWPREP to TPS76801QPWPRQ1?

A: The physical package (20-PowerTSSOP) and pin configuration remain identical. The difference is in supply format: Tape & Reel versus Cut Tape & Digi-Reel. This affects procurement and handling but does not impact circuit board assembly or electrical performance.

Q: What should be verified before implementing the substitute in production?

A: Confirm that the application's operating temperature range does not require operation below -40°C. Verify component availability and lead times through authorized distributors. Validate that the substitute's packaging format aligns with assembly equipment and procurement workflows.
