Key Parameters

Substitute Part Grouping Explanation

Substitution of the UCC2804QDRCT is determined by alignment across the following critical parameters:

Functional Compatibility: The substitute component must operate as a PWM Controller suitable for offline switch applications in power supply topologies.

Electrical Specifications: Input voltage range, supply voltage range, supply current, and operating temperature range must be equivalent or superior to the original component specifications.

Package Compatibility: The substitute must be available in 8-SOIC surface mount packaging to ensure mechanical and electrical compatibility with existing PCB layouts.

Compliance & Certification: The substitute must maintain ROHS3 compliance and REACH unaffected status. Automotive-grade qualification (AEC-Q100) is required for applications demanding automotive reliability standards.

Product Status: Active or equivalent status is required to ensure long-term availability and supply chain continuity.

The primary substitute identified is UCC2804QDRQ1, which maintains identical functional classification, electrical parameters, and packaging while offering Active product status and superior inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The UCC2804QDRQ1 is the qualified substitute for the UCC2804QDRCT based on the following engineering criteria:

Functional Equivalence: Both components share identical base product number (UCC2804) and operate as PWM Controllers for offline switch applications. Electrical parameters including input voltage, supply voltage, supply current, and operating temperature range are identical across both variants.

Package Compatibility: Both components are housed in 8-SOIC surface mount packaging with identical physical dimensions (0.154", 3.90mm Width), ensuring direct PCB layout compatibility without redesign requirements.

Compliance Alignment: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for both commercial and automotive applications.

Automotive Qualification: Both components carry AEC-Q100 automotive qualification, meeting reliability and quality standards for automotive-grade power supply applications.

Supply Chain Continuity: The UCC2804QDRQ1 maintains Active product status with significantly higher inventory availability (3820 Pcs versus 1129 Pcs), providing superior long-term supply security compared to the Last Time Buy UCC2804QDRCT.

Moisture Sensitivity: Both components share MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the UCC2804QDRQ1 be used as a direct replacement for the UCC2804QDRCT?

A: Yes. The UCC2804QDRQ1 is a direct functional and electrical equivalent. Both components share identical electrical specifications, package format, and compliance certifications. No circuit modifications or PCB redesign is required for substitution.

Q: Are there differences in the packaging format between these components?

A: Both components are supplied in Tape & Reel (TR) format within 8-SOIC surface mount packaging. Physical dimensions and pin configurations are identical, ensuring compatibility with existing pick-and-place equipment and PCB layouts.

Q: What is the significance of the Last Time Buy status for the UCC2804QDRCT?

A: Last Time Buy status indicates that the UCC2804QDRCT is no longer in active production and existing inventory represents the final available supply. Substitution to the Active-status UCC2804QDRQ1 is recommended to ensure continued availability for future production runs and design iterations.

Q: Do both components meet automotive qualification requirements?

A: Yes. Both the UCC2804QDRCT and UCC2804QDRQ1 carry AEC-Q100 automotive qualification and are classified as Automotive grade, meeting reliability and quality standards for automotive power supply applications.

Q: Are there any compliance or regulatory differences between these components?

A: No. Both components maintain identical ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for both commercial and automotive markets without additional compliance considerations.

Q: What is the MSL rating for these components?

A: Both components carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints. Standard handling and storage procedures are sufficient without specialized moisture control measures.
