UCC28610P Equivalent & Substitute Parts

Part Overview

The UCC28610P is an offline switch flyback converter IC manufactured by Texas Instruments, designed for isolated power management applications. This device operates in the 30kHz to 133kHz switching frequency range with a maximum power rating of 65W and supports supply voltages from 8V to 25V. The UCC28610P is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The primary substitute maintains identical electrical specifications while offering improved availability through active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UCC28610P is determined by strict equivalence across all electrical and functional parameters. The UCC28610D qualifies as a direct substitute because it maintains identical specifications in the following critical areas:

• Topology and control architecture (Flyback converter)
• Electrical performance (8V ~ 25V supply, 10.2V startup, 30kHz ~ 133kHz switching)
• Power handling capability (65W maximum)
• Protection features (Current Limiting, Over Temperature, Over Voltage)
• Operating temperature range (-40°C ~ 150°C)
• Compliance certifications (ROHS3, REACH Unaffected)
• Base product number (UCC28610)

The only difference between these parts is the package type and mounting technology, which is a mechanical consideration rather than an electrical one.

Engineering Selection Recommendations

The UCC28610D is the manufacturer-recommended substitute for the obsolete UCC28610P. Selection between these parts depends on board design and manufacturing process:

For through-hole assembly processes or existing PCB designs with DIP footprints, the UCC28610P remains functional where inventory is available. However, the UCC28610P's obsolete status creates long-term supply risk.

For new designs or PCB redesigns, the UCC28610D is the appropriate choice. This part carries active product status from Texas Instruments, ensuring continued availability and manufacturing support. The UCC28610D uses surface-mount technology (8-SOIC package), which aligns with modern PCB assembly standards and reduces board space requirements compared to the through-hole DIP package.

Both parts maintain identical electrical performance, protection features, and compliance certifications (ROHS3 Compliant, REACH Unaffected). The selection decision is therefore driven by manufacturing capability and supply chain requirements rather than functional considerations.

Frequently Asked Questions (FAQ)

Q: Can the UCC28610D directly replace the UCC28610P in existing designs?

A: Electrical substitution is complete. However, the UCC28610D uses a different package (8-SOIC surface mount versus 8-DIP through hole). PCB redesign is required to accommodate the different footprint and mounting technology.

Q: Why is the UCC28610P classified as obsolete?

A: Product obsolescence is determined by the manufacturer. The UCC28610D, which shares identical electrical specifications, is the active replacement part.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts operate identically across all specified parameters: supply voltage range, switching frequency, power rating, protection features, and operating temperature range.

Q: What is the significance of the different package types?

A: The UCC28610P uses an 8-DIP through-hole package (0.300" width), while the UCC28610D uses an 8-SOIC surface-mount package (0.154" width). This affects PCB layout, assembly process, and board space utilization but not electrical function.

Q: Are both parts compliant with current environmental standards?

A: Yes. Both the UCC28610P and UCC28610D are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
