TPS54350MPWPREP Equivalent & Substitute Parts

Part Overview

The TPS54350MPWPREP is a buck switching regulator IC from Texas Instruments' SWIFT™ series, designed for step-down voltage conversion with positive adjustable output. This Active product delivers 3A output current across an input voltage range of 4.5V to 20V, with adjustable output from 0.891V to 17.2V. The device operates at switching frequencies of 250kHz or 500kHz and includes a synchronous rectifier for improved efficiency. Surface mount packaging in 16-PowerTSSOP format enables compact board integration. Substitute parts are identified when packaging format differs while maintaining identical electrical specifications and functional performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS54350MPWPREP is determined by strict equivalence across the following electrical and mechanical parameters:

• Base product number (TPS54350)
• Manufacturer (Texas Instruments)
• Functional topology (Buck regulator)
• Output configuration (Positive adjustable)
• Input voltage range (4.5V to 20V)
• Output voltage range (0.891V to 17.2V)
• Output current rating (3A)
• Switching frequency (250kHz, 500kHz)
• Synchronous rectifier presence
• Package type (16-PowerTSSOP)
• Mounting type (Surface Mount)

The TPS54350PWPR qualifies as a direct substitute based on identical electrical specifications and package format. The distinction between these parts lies exclusively in packaging configuration: TPS54350MPWPREP is supplied in Tape & Reel (TR) format, while TPS54350PWPR is supplied in Cut Tape (CT) & Digi-Reel® format. Both parts share the same die, performance characteristics, and reliability ratings.

Parameter Comparison

Engineering Selection Recommendations

Both TPS54350MPWPREP and TPS54350PWPR are Active products from Texas Instruments with identical electrical performance and compliance certifications. Selection between these parts is determined by supply chain requirements and packaging format availability.

The TPS54350MPWPREP in Tape & Reel format is suitable for high-volume automated assembly operations where continuous reel feeding optimizes pick-and-place efficiency. The TPS54350PWPR in Cut Tape & Digi-Reel® format accommodates lower-volume production runs, prototyping, and applications requiring flexible quantity management.

Operating temperature range differs slightly: TPS54350MPWPREP supports -55°C to 125°C, while TPS54350PWPR supports -40°C to 125°C. Applications requiring extended low-temperature operation below -40°C must use TPS54350MPWPREP.

Both parts maintain ROHS3 compliance, MSL Level 2 rating, and REACH unaffected status, ensuring regulatory compatibility across industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can TPS54350PWPR replace TPS54350MPWPREP in production?

A: Yes, provided operating temperature requirements do not exceed -40°C minimum. Both parts share identical electrical specifications, die design, and package dimensions. The difference is packaging format only: Tape & Reel versus Cut Tape & Digi-Reel®.

Q: What is the significance of the packaging format difference?

A: Tape & Reel (TR) format supplies components on continuous reels optimized for automated high-speed assembly. Cut Tape (CT) & Digi-Reel® format provides pre-cut tape segments suitable for lower-volume production, manual assembly, and component distribution. Electrical performance is identical.

Q: Are there thermal performance differences between these parts?

A: No. Both parts use the same silicon die and package construction. Thermal characteristics, including junction-to-ambient thermal resistance and power dissipation capability, are identical.

Q: Does the operating temperature range difference affect component selection?

A: Only if your application requires operation below -40°C. The TPS54350MPWPREP supports -55°C minimum junction temperature, while TPS54350PWPR supports -40°C minimum. For applications within -40°C to 125°C range, both parts are functionally equivalent.

Q: Are both parts currently in production?

A: Yes. Both TPS54350MPWPREP and TPS54350PWPR maintain Active product status from Texas Instruments.

Q: What certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 2 (1 Year) moisture sensitivity rating. ECCN classification is EAR99 for both parts.
