TPS54316MPWPREP Equivalent & Substitute Parts

Part Overview

The TPS54316MPWPREP is a buck switching regulator IC from Texas Instruments' SWIFT™ series, designed for step-down voltage conversion with a fixed 3.3V output at 3A maximum current. This Active product operates across a 3V to 6V input range with a 20-PowerTSSOP surface mount package. The device features synchronous rectification and operates at switching frequencies of 350kHz or 550kHz.

Substitute parts are identified when packaging format differs while maintaining identical electrical specifications and mechanical compatibility, enabling procurement flexibility without design modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS54316MPWPREP is determined by equivalence across the following critical parameters:

• Base product number (TPS54316)
• Output voltage specification (3.3V fixed)
• Output current rating (3A)
• Input voltage range (3V to 6V)
• Package footprint (20-PowerTSSOP)
• Electrical topology (buck converter with synchronous rectification)
• Switching frequency (350kHz, 550kHz)

The primary distinction between the main part and substitute parts lies in packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) and operating temperature range. These differences do not affect electrical performance or PCB-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS54316MPWPREP and TPS54316PWPR are Active products from Texas Instruments with identical electrical specifications and mechanical compatibility. Selection between these parts is determined by procurement requirements and packaging format availability.

The TPS54316MPWPREP is supplied in Tape & Reel format, suitable for high-volume automated assembly operations. The TPS54316PWPR is supplied in Cut Tape & Digi-Reel® format, accommodating lower-volume requirements or mixed component sourcing scenarios.

Both parts maintain ROHS3 compliance, identical MSL ratings, and equivalent functional performance. The operating temperature range difference (TPS54316MPWPREP: -55°C to 125°C junction; TPS54316PWPR: -40°C to 85°C ambient) reflects measurement methodology rather than device capability differences and does not affect substitution eligibility for standard industrial applications.

Frequently Asked Questions (FAQ)

Q: Can TPS54316PWPR replace TPS54316MPWPREP in production?

A: Yes. Both parts share identical electrical specifications, output voltage (3.3V), output current (3A), input voltage range (3V to 6V), package footprint (20-PowerTSSOP), and switching frequency characteristics. Substitution requires no circuit design changes.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for high-speed automated pick-and-place assembly. Cut Tape & Digi-Reel® packaging supplies components on cut tape segments or alternative reel formats, suitable for lower-volume production or component kit assembly. Both formats contain identical components with identical electrical performance.

Q: Are there operating temperature restrictions when substituting these parts?

A: The TPS54316MPWPREP specifies -55°C to 125°C junction temperature range, while TPS54316PWPR specifies -40°C to 85°C ambient temperature range. For applications operating within -40°C to 85°C, both parts are functionally equivalent. Applications requiring operation below -40°C or above 85°C should verify compatibility with the specific temperature measurement methodology and thermal design of the application.

Q: Do both parts require identical PCB layout and external component selection?

A: Yes. Both parts use the identical 20-PowerTSSOP package footprint and share all electrical specifications. PCB layout, external component values, and circuit topology remain unchanged when substituting between these parts.

Q: Are both parts currently available for new designs?

A: Yes. Both TPS54316MPWPREP and TPS54316PWPR maintain Active product status from Texas Instruments and are suitable for new design implementations.
