TPS54352PWPRG4 Equivalent & Substitute Parts

Part Overview

The TPS54352PWPRG4 is a buck switching regulator IC from Texas Instruments' SWIFT™ series, designed for step-down voltage conversion with a fixed 1.2V output at 3A maximum current. The device operates across a 4.5V to 20V input range and features a 250kHz/500kHz switching frequency with integrated synchronous rectification. This part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution of the TPS54352PWPRG4 is determined by strict equivalence across the following critical parameters:

  • Output Voltage & Current: Fixed 1.2V output at 3A maximum
  • Input Voltage Range: 4.5V to 20V operation
  • Topology & Function: Buck switching regulator with synchronous rectification
  • Package & Pinout: 16-PowerTSSOP form factor
  • Electrical Characteristics: 250kHz/500kHz switching frequency capability
  • Compliance & Certifications: ROHS3 compliance, EAR99 classification, REACH unaffected status

The TPS54352PWPR qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is packaging format (Tape & Reel vs. standard packaging) and product lifecycle status.

Engineering Selection Recommendations

The TPS54352PWPR is a direct electrical and mechanical equivalent to the TPS54352PWPRG4. Both devices share identical core specifications, including output voltage, current rating, input voltage range, switching frequency, and package configuration. The substitution is valid from an engineering perspective based on:

  • Identical electrical performance characteristics
  • Matching 16-PowerTSSOP package footprint and pinout
  • Equivalent thermal and environmental operating ranges
  • Identical compliance certifications (ROHS3, EAR99, REACH unaffected)
  • Same moisture sensitivity classification

The primary consideration is packaging format: TPS54352PWPR is supplied in Tape & Reel format, which may affect procurement workflows and minimum order quantities. The TPS54352PWPR carries a "Last Time Buy" status, indicating limited future availability. For long-term production requirements, alternative sourcing strategies should be evaluated.

Frequently Asked Questions (FAQ)

Q: Can TPS54352PWPR be used as a direct replacement for TPS54352PWPRG4?

A: Yes. Both parts are electrically and mechanically identical. They share the same output voltage (1.2V), current rating (3A), input voltage range (4.5V–20V), switching frequency (250kHz/500kHz), and 16-PowerTSSOP package configuration. The only difference is the packaging format (Tape & Reel vs. standard).

Q: What is the difference between TPS54352PWPRG4 and TPS54352PWPR?

A: The primary difference is packaging format. TPS54352PWPRG4 uses standard packaging, while TPS54352PWPR is supplied in Tape & Reel (TR) format. All electrical specifications and package footprints are identical.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist from an electrical or mechanical standpoint. Both parts are pin-compatible and functionally equivalent. PCB layout and external component requirements remain unchanged.

Q: What does "Last Time Buy" status mean for TPS54352PWPR?

A: "Last Time Buy" indicates that the manufacturer has announced end-of-life for this product. Existing inventory may be available, but future production is not planned. Procurement should account for this limited availability window.

Q: Are both parts RoHS compliant?

A: Yes. Both TPS54352PWPRG4 and TPS54352PWPR are ROHS3 compliant with identical moisture sensitivity levels (MSL 2, 1 Year).
