UCC2580D-4 Equivalent & Substitute Parts

Part Overview

The UCC2580D-4 is an offline switching controller IC manufactured by Texas Instruments, designed for flyback and forward converter topologies in isolated power management applications. This device operates as a PMIC (Power Management Integrated Circuit) in a 16-SOIC surface mount package. The UCC2580D-4 is currently in Last Time Buy status, indicating end-of-life production. Identifying equivalent substitute parts is necessary to ensure design continuity and maintain supply chain reliability for new production runs and long-term system support.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UCC2580D-4 are identified based on strict equivalence across the following critical parameters:

• Identical base product number (UCC2580)
• Matching package type (16-SOIC)
• Identical electrical specifications (supply voltage range, startup voltage, duty cycle, topology support)
• Identical control features (soft start functionality)
• Identical operating temperature range (-55°C ~ 150°C)
• Identical isolation and internal switch configuration
• Matching compliance certifications (ROHS3, REACH Unaffected)

The primary difference between the main part and substitute is the packaging format: the UCC2580D-4 uses Tube packaging, while the substitute UCC2580DTR-2 uses Tape & Reel (TR) packaging. Both formats are standard surface mount delivery methods with no impact on device functionality or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The UCC2580DTR-2 is a direct functional equivalent to the UCC2580D-4. Both devices share identical electrical specifications, thermal performance, and compliance certifications. The UCC2580DTR-2 is recommended as the primary substitute due to its Active product status, ensuring continued availability and manufacturing support from Texas Instruments.

The only distinction is packaging format: Tube versus Tape & Reel. This difference affects supply chain logistics and automated assembly compatibility but does not impact device performance, pinout, or electrical characteristics. Selection between these formats depends on production volume and assembly equipment capabilities.

Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for current and future applications.

Frequently Asked Questions (FAQ)

Q: Can the UCC2580DTR-2 be used as a direct replacement for the UCC2580D-4 in existing designs?

A: Yes. The UCC2580DTR-2 is electrically and functionally identical to the UCC2580D-4. No circuit modifications, firmware changes, or design alterations are required. Both devices operate identically in flyback and forward converter topologies with the same electrical specifications and performance characteristics.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging delivers components in plastic tubes suitable for manual handling and small-volume assembly. Tape & Reel (TR) packaging delivers components on continuous tape wound on reels, optimized for high-speed automated pick-and-place assembly equipment. Both formats contain identical devices with no functional differences.

Q: Why is the UCC2580D-4 in Last Time Buy status?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this specific part number variant. The UCC2580DTR-2 remains in Active status, meaning it continues to be manufactured and supported. Transitioning to the UCC2580DTR-2 ensures long-term supply chain continuity.

Q: Are there any thermal or reliability differences between these part numbers?

A: No. Both devices share identical operating temperature ranges (-55°C ~ 150°C junction temperature), thermal characteristics, and reliability specifications. Moisture Sensitivity Level (MSL) is identical at Level 1 (Unlimited), indicating no moisture-related handling restrictions.

Q: What compliance certifications apply to both parts?

A: Both the UCC2580D-4 and UCC2580DTR-2 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components in industrial and commercial applications.
