UCC28250RGPR Equivalent & Substitute Parts

Part Overview

The UCC28250RGPR is an active, production-status DC-DC controller IC from Texas Instruments designed for multi-topology power management applications. This device functions as a Full-Bridge, Half-Bridge, and Push-Pull regulator controller, delivering PWM signals for positive output step-up/step-down conversion. The UCC28250RGPR is housed in a 20-QFN (4x4) surface mount package with exposed pad and is supplied in Tape & Reel packaging.

Alternative equivalent parts become necessary when primary inventory is unavailable, when supply chain constraints affect lead times, or when design flexibility permits selection from qualified substitute devices that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the UCC28250RGPR is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Texas Instruments
• Package / Case: 20-VFQFN Exposed Pad
• Mounting Type: Surface Mount
• Voltage Supply Range (Vcc/Vdd): 4.7V ~ 17V
• Operating Temperature Range: -40°C ~ 125°C (TJ)
• Output Type: PWM Signal
• Output Configuration: Positive
• Topology: Full-Bridge, Half-Bridge, Push-Pull
• Number of Outputs: 2
• Product Status: Active
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 2 (1 Year)

The identified substitute parts maintain full parametric equivalence across all electrical and mechanical specifications. Variations in switching frequency range and base product numbering do not affect functional interchangeability within the defined application envelope.

Parameter Comparison

Engineering Selection Recommendations

All three parts—UCC28250RGPR, UCC28250RGPT, and UCC28251RGPT—carry Active product status and maintain full ROHS3 compliance with identical MSL ratings. Selection among these equivalents is based on inventory availability and application-specific switching frequency requirements.

The UCC28250RGPR and UCC28250RGPT share identical switching frequency specifications (85kHz ~ 1.15MHz) and differ only in packaging designation. The UCC28251RGPT operates within a lower switching frequency envelope (42kHz ~ 945kHz) while maintaining all other electrical and mechanical equivalence.

All parts are supplied in Tape & Reel format suitable for automated assembly processes and meet identical regulatory and environmental compliance standards.

Frequently Asked Questions (FAQ)

Q: Can UCC28250RGPT be used as a direct replacement for UCC28250RGPR?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications. The difference in part number suffix reflects packaging designation only. Both maintain identical switching frequency range, supply voltage specifications, and thermal operating range.

Q: What is the functional difference between UCC28250RGPT and UCC28251RGPT?

A: The primary difference is the switching frequency operating range. UCC28250RGPT operates from 85kHz to 1.15MHz, while UCC28251RGPT operates from 42kHz to 945kHz. All other electrical characteristics, package specifications, and compliance certifications remain identical. Selection depends on application-specific frequency requirements.

Q: Are all three parts suitable for the same PCB layout and thermal design?

A: Yes. All three parts use the identical 20-VFQFN Exposed Pad package with surface mount configuration. PCB footprints, thermal management approaches, and assembly processes are interchangeable.

Q: What compliance certifications apply to these substitute parts?

A: All three parts maintain ROHS3 compliance, carry MSL rating of 2 (1 Year), and hold Active product status from Texas Instruments. REACH status is Unaffected for all variants.

Q: How does inventory availability affect part selection?

A: Current inventory levels are: UCC28250RGPR (3200 Pcs), UCC28250RGPT (2200 Pcs), and UCC28251RGPT (1111 Pcs). Selection may be influenced by lead time requirements and supply chain constraints, provided the switching frequency specification aligns with application requirements.
