TPS54073PWPR Equivalent & Substitute Parts

Part Overview

The TPS54073PWPR is a buck switching regulator IC from Texas Instruments' SWIFT™ series, designed for positive adjustable step-down voltage regulation. It delivers 14A output current with an adjustable output range from 0.9V to 3.6V, operating from a 3V to 4V input supply. The device features synchronous rectification and operates at switching frequencies between 280kHz and 700kHz.

The TPS54073PWPR is classified as Obsolete. Locating equivalent or substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS54073PWPR is determined by strict equivalence across the following critical parameters:

• Topology & Function: Buck (step-down) switching regulator with positive adjustable output
• Electrical Specifications: Input voltage range 3V–4V, output voltage range 0.9V–3.6V, 14A output current capability
• Switching Frequency: Operating range 280kHz–700kHz
• Synchronous Rectification: Integrated synchronous rectifier required
• Package & Mounting: 28-PowerTSSOP surface mount package with identical physical dimensions
• Compliance: ROHS3 compliant, MSL 2 rating

The TPS54073PWP meets all these criteria and is classified as a manufacturer-recommended substitute. Both parts share the same base product number (TPS54073) and are from the SWIFT™ series.

Parameter Comparison

Engineering Selection Recommendations

The TPS54073PWP is the manufacturer-recommended substitute for the TPS54073PWPR. Both devices are electrically and mechanically identical, with all critical parameters matching exactly. The primary distinction is product lifecycle status: the TPS54073PWPR is Obsolete, while the TPS54073PWP is in Last Time Buy status, indicating extended availability for procurement.

For new designs or ongoing production requiring this buck regulator topology, the TPS54073PWP should be selected. Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring compatibility with existing supply chain and manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can the TPS54073PWP be used as a direct replacement for the TPS54073PWPR?

A: Yes. The TPS54073PWP is electrically and mechanically identical to the TPS54073PWPR. All electrical specifications, package dimensions, and compliance certifications are equivalent. Direct substitution is supported without circuit modification.

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

A: The TPS54073PWPR and TPS54073PWP differ only in product lifecycle status. The TPS54073PWPR is Obsolete, while the TPS54073PWP is Last Time Buy. Both are from the same SWIFT™ series and share identical electrical and mechanical characteristics.

Q: Are there any package or pinout differences?

A: No. Both parts use the 28-PowerTSSOP package with identical pinout, physical dimensions (0.173" × 4.40mm width), and mounting requirements. PCB layouts and footprints are fully compatible.

Q: What compliance certifications apply to both parts?

A: Both the TPS54073PWPR and TPS54073PWP are ROHS3 compliant with MSL 2 (1 Year) moisture sensitivity rating. REACH status is Unaffected for both devices.

Q: Which part should be selected for new procurement?

A: The TPS54073PWP should be selected for new orders and ongoing production. As the Last Time Buy option, it offers extended availability compared to the Obsolete TPS54073PWPR.
