NCL30002DR2G LED Driver IC Equivalent & Substitute Parts

Part Overview

The NCL30002DR2G is an AC DC offline switcher LED driver IC manufactured by onsemi, designed for lighting applications with a step-down (buck) topology. This part is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. The NCL30002DR2G operates with a supply voltage range of 10.2V to 20V and is packaged in an 8-SOIC surface mount configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the NCL30002DR2G are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• AC DC offline switcher topology classification
• Single output configuration
• Surface mount 8-SOIC package compatibility
• Operating temperature range overlap (-40°C minimum)
• ROHS3 compliance and MSL rating
• LED driver application suitability

The three substitute parts listed (AL1692-30BS7-13, LYT0006D-TL, and MP4001DS-LF-Z) meet these core requirements, though each offers different topology options and supply voltage ranges. Substitution feasibility depends on the specific circuit topology requirements of the target application.

Parameter Comparison

Engineering Selection Recommendations

AL1692-30BS7-13 (Diodes Incorporated): Active product status with ROHS3 compliance and unlimited MSL rating. Supports multiple topologies (Flyback, Buck, Boost) with internal switching capability. Operating temperature maximum of 105°C is 20°C lower than the original part. Supply voltage range of 8.5V to 18V is narrower than MP4001DS-LF-Z but overlaps the NCL30002DR2G operating window. Suitable for applications requiring flexible topology support.

LYT0006D-TL (Power Integrations): Active product with RoHS compliance and unlimited MSL. Operates on AC input (85VAC to 308VAC), fundamentally different from the NCL30002DR2G DC supply requirement. Includes internal switching and supports multiple topologies. Operating temperature range matches the original part (-40°C to 125°C). Selection requires confirmation that AC input compatibility aligns with application requirements.

MP4001DS-LF-Z (Monolithic Power Systems Inc.): Active product with ROHS3 compliance. Maintains step-down (buck) topology matching the NCL30002DR2G. Widest supply voltage range (12V to 450V) among substitutes. Operating temperature range identical to original part. MSL rating of 2 (1 Year) requires moisture control during storage and handling. Automotive grade classification available. Recommended for direct topology replacement in DC supply applications.

Frequently Asked Questions (FAQ)

Q: Can AL1692-30BS7-13 directly replace NCL30002DR2G? A: AL1692-30BS7-13 shares the 8-SOIC package and AC DC offline switcher classification. However, it includes internal switching capability (versus none in NCL30002DR2G) and supports additional topologies. The maximum operating temperature is 105°C versus 125°C for the original part. Circuit redesign may be required to utilize the additional topology options.

Q: What is the primary difference between LYT0006D-TL and the other substitutes? A: LYT0006D-TL operates on AC input voltage (85VAC to 308VAC), whereas NCL30002DR2G and other substitutes operate on DC supply voltages. This fundamental difference requires application-level compatibility verification before selection.

Q: Is MP4001DS-LF-Z suitable for direct replacement? A: MP4001DS-LF-Z maintains the step-down (buck) topology of NCL30002DR2G and operates on DC supply (12V to 450V). Operating temperature range (-40°C to 125°C) and package type (8-SOIC) are identical. The MSL rating of 2 requires standard moisture control procedures. This part is the closest functional equivalent for DC-based buck converter applications.

Q: What does MSL rating 2 mean for MP4001DS-LF-Z? A: MSL 2 indicates a 1-year floor life requirement. The component must be stored in controlled humidity conditions and used within one year of manufacture. This is more restrictive than the unlimited MSL of other substitutes but manageable with standard component handling procedures.

Q: Are all substitutes ROHS3 compliant? A: AL1692-30BS7-13 and MP4001DS-LF-Z are ROHS3 compliant. LYT0006D-TL is RoHS compliant but not specifically ROHS3 certified. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: Can these parts be used interchangeably in the same PCB layout? A: All substitutes use 8-SOIC or compatible 7-SO/SO-8C packages with 0.154" width. Physical footprint compatibility exists for most layouts. However, internal pin configuration and functional requirements may differ. PCB schematic and layout review is necessary before substitution.
