UCC28630DR Equivalent & Substitute Parts

Part Overview

The UCC28630DR is an offline switch flyback converter IC manufactured by Texas Instruments, designed for isolated power management applications. This active product operates across a 200Hz to 120kHz switching frequency range with 30W power handling capability and integrated fault protection including current limiting, overload, over-temperature, and over-voltage protection. The device is housed in a 7-SOIC surface mount package and is ROHS3 compliant with MSL 2 rating.

Alternative equivalent parts may be required due to inventory constraints, supply chain disruptions, or design optimization needs while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The UCC28633DR qualifies as a parametric equivalent to the UCC28630DR based on strict alignment across all critical electrical and mechanical parameters. Substitution eligibility is determined by matching the following key criteria:

Topology and isolation architecture (Flyback, Isolated output), voltage supply range (8V ~ 20V), startup voltage (14.75V), switching frequency range (200Hz ~ 120kHz), duty cycle (70%), power rating (30W), fault protection features (Current Limiting, Over Load, Over Temperature, Over Voltage), operating temperature range (-40°C ~ 125°C), package type (7-SOIC surface mount), and compliance certifications (ROHS3, MSL 2).

The UCC28633DR maintains identical specifications across all these parameters, enabling direct substitution in applications where the UCC28630DR is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the UCC28630DR and UCC28633DR are active products from Texas Instruments with full ROHS3 compliance and identical MSL 2 ratings. Selection between these parts should be based on availability and supply chain considerations. Both devices meet all regulatory and environmental compliance requirements for deployment in equivalent applications. The identical electrical specifications, package geometry, and fault protection architecture ensure functional interchangeability without design modification.

Frequently Asked Questions (FAQ)

Q: Can the UCC28633DR replace the UCC28630DR in existing designs?

A: Yes. The UCC28633DR is a parametric equivalent with identical electrical specifications, switching characteristics, power rating, fault protection features, and package configuration. No circuit modifications are required.

Q: Are the pin configurations identical between these parts?

A: Yes. Both devices use the 7-SOIC surface mount package with 8-pin configuration (0.154" width, 3.90mm). Pin assignments and lead spacing are identical.

Q: Do both parts have the same compliance certifications?

A: Yes. Both the UCC28630DR and UCC28633DR are ROHS3 compliant with MSL 2 moisture sensitivity rating and 1-year shelf life under controlled conditions.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching topology (Flyback), isolation architecture (Isolated), voltage supply range (8V ~ 20V), switching frequency (200Hz ~ 120kHz), power rating (30W), fault protection features, operating temperature range (-40°C ~ 125°C), and package type (7-SOIC surface mount).

Q: Can these parts be used interchangeably in production?

A: Yes. Both parts meet identical specifications and are suitable for direct substitution in manufacturing environments without design changes or additional qualification.
