TPS76718QPWPR Equivalent & Substitute Parts

Part Overview

The TPS76718QPWPR is a linear voltage regulator IC manufactured by Texas Instruments, designed for positive fixed output applications. This device delivers 1A output current at a fixed 1.8V output voltage and operates across an input voltage range up to 10V. The part is actively produced and widely used in power management applications requiring stable low-voltage regulation with integrated protection features. Substitute parts are identified to provide design flexibility, inventory alternatives, and continuity of supply for applications where the primary part may have limited availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS76718QPWPR are identified based on strict electrical and mechanical parameter matching. The critical parameters that determine substitution eligibility are:

• Output voltage configuration: Positive fixed 1.8V
• Output current capability: 1A
• Input voltage maximum rating: 10V
• Package type: 20-PowerTSSOP surface mount
• Control features: Enable and Reset functionality
• Protection mechanisms: Over Current, Over Temperature, Reverse Polarity protection
• Operating temperature range: -40°C to 125°C
• Compliance certifications: ROHS3 Compliant

The TPS76718QPWPREP is classified as a parametric equivalent because it maintains identical electrical specifications and mechanical packaging, differing only in inventory status and supplier device package designation.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS76718QPWPR and TPS76718QPWPREP are active products manufactured by Texas Instruments with identical electrical and mechanical specifications. Selection between these parts should be based on availability and supply chain requirements. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The TPS76718QPWPR currently maintains higher inventory levels (3400 Pcs), while the TPS76718QPWPREP provides an alternative source with 607 Pcs available. For applications requiring immediate availability or long-term supply assurance, either part is suitable for direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the TPS76718QPWPREP be used as a direct replacement for the TPS76718QPWPR?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage (1.8V fixed), output current (1A), input voltage rating (10V maximum), control features (Enable, Reset), protection mechanisms (Over Current, Over Temperature, Reverse Polarity), and package type (20-PowerTSSOP). Direct substitution is possible without circuit modification.

Q: Are there any differences in the package or mounting requirements?

A: No. Both parts use the identical 20-PowerTSSOP surface mount package with 0.173" width (4.40mm). PCB layout, footprint, and assembly processes remain unchanged between the two parts.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching output voltage (1.8V fixed), output current capability (1A), input voltage maximum (10V), package type (20-PowerTSSOP), control features (Enable, Reset), protection features (Over Current, Over Temperature, Reverse Polarity), and operating temperature range (-40°C to 125°C).

Q: Do both parts meet the same compliance standards?

A: Yes. Both the TPS76718QPWPR and TPS76718QPWPREP are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings (2, 1 Year). Regulatory and environmental compliance is equivalent.

Q: What is the difference between these two part numbers?

A: The parts are functionally and electrically identical. The difference lies in the supplier device package designation and current inventory availability. The TPS76718QPWPR has 3400 units in stock, while the TPS76718QPWPREP has 607 units available.
