Key Parameters

Substitute Part Grouping Explanation

Substitution of the UCD8220PWPR is determined by strict equivalence across the following critical parameters:

• Identical output type (Transistor Driver)
• Matching function (Step-Up/Step-Down DC-DC Controller)
• Identical topology support (Full-Bridge, Half-Bridge, Push-Pull)
• Matching output configuration (Positive, Isolation Capable)
• Identical number of outputs (2)
• Identical supply voltage range (4.5V ~ 15.5V)
• Matching switching frequency capability (Up to 2MHz)
• Identical control features (Current Limit)
• Identical package type (16-PowerTSSOP)
• Identical mounting type (Surface Mount)
• Matching RoHS compliance (ROHS3 Compliant)

The UCD8220QPWPRQ1 meets all substitution criteria and is classified as an active product with automotive-grade qualification (AEC-Q100), providing enhanced long-term availability compared to the obsolete UCD8220PWPR.

Parameter Comparison

Engineering Selection Recommendations

The UCD8220QPWPRQ1 is the direct substitute for the obsolete UCD8220PWPR. Both components share identical electrical and mechanical specifications across all critical parameters that determine functional compatibility.

The UCD8220QPWPRQ1 offers the following advantages:

• Active product status ensures ongoing availability and manufacturing support
• Automotive-grade qualification (AEC-Q100) provides enhanced reliability documentation
• Extended operating temperature range (-40°C ~ 125°C TJ vs. -40°C ~ 105°C TA) supports broader thermal environments
• Tape & Reel packaging supports automated assembly processes
• ROHS3 compliance maintained across both parts

Selection of the UCD8220QPWPRQ1 is appropriate for all applications currently specified for the UCD8220PWPR without circuit modification or re-qualification, provided that the extended temperature range and automotive-grade certification are compatible with application requirements.

Frequently Asked Questions (FAQ)
