Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPHWW1HDNB27YHT3B3 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Product Type: Chip On Board (COB) configuration
• Color: White, Neutral
• CCT (Color Temperature): 4000K 3-Step MacAdam Ellipse
• Configuration: Square
• Viewing Angle: 115°
• Manufacturer: Samsung Semiconductor, Inc.

Secondary Compatibility Criteria:

• Lens Type: Flat
• Moisture Sensitivity Level: MSL 1 or equivalent
• Export Classification: EAR99
• HTSUS Code: 8541.41.0000

The substitute part SPHWHAHDNG28YZT3D2 satisfies all primary compatibility criteria and maintains alignment with secondary compliance parameters. While the substitute represents a different series generation (COB D Gen2 versus LC019B Gen3), both components share identical color temperature specification, configuration, viewing angle, and lens type characteristics essential for functional equivalence in lighting applications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SPHWW1HDNB27YHT3B3 carries Obsolete status, while the substitute SPHWHAHDNG28YZT3D2 maintains Active product status. This distinction is significant for long-term supply chain planning and component availability assurance.

Compliance Alignment: Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring equivalent export and tariff treatment.

Functional Equivalence: Both components deliver 4000K color temperature with 115° viewing angle and flat lens configuration. The substitute provides higher absolute luminous flux (2786lm versus 2578lm nominal) and supports higher maximum current (1.84A versus 980mA), indicating enhanced performance capability within the same form factor class.

Physical Considerations: The substitute component features larger overall dimensions (19.00mm x 19.00mm versus 17.00mm x 17.00mm) and larger light emitting surface diameter (14.50mm versus 12.40mm). These dimensional differences require verification against mechanical mounting constraints and optical system design parameters in the target application.

Electrical Parameter Differences: Forward voltage differs marginally (34.6V versus 35.5V), representing a 0.9V reduction. Test current specifications reflect different measurement conditions (85°C for substitute versus 25°C for main part). Lumens per watt efficiency differs (112 lm/W versus 134 lm/W), reflecting generation-based performance variations between LC019B Gen3 and COB D Gen2 series.

Frequently Asked Questions (FAQ)

Q: Can SPHWHAHDNG28YZT3D2 directly replace SPHWW1HDNB27YHT3B3 in existing designs?

A: Functional substitution is supported based on matching color temperature (4000K), configuration (square), viewing angle (115°), and lens type (flat). However, dimensional differences (19mm x 19mm versus 17mm x 17mm) and electrical parameter variations require design review to confirm mechanical fit and circuit compatibility.

Q: What are the key differences between these two components?

A: The components differ in series generation (LC019B Gen3 versus COB D Gen2), overall dimensions, light emitting surface diameter, electrical performance characteristics, and product status (Obsolete versus Active). Color temperature, configuration, and viewing angle remain identical.

Q: Why is the substitute part larger?

A: The SPHWHAHDNG28YZT3D2 represents a newer generation COB design with larger emitting surface (14.50mm versus 12.40mm diameter) and increased overall footprint (19mm x 19mm versus 17mm x 17mm). This design evolution supports higher luminous flux output and maximum current capability.

Q: Are there packaging differences?

A: The main part SPHWW1HDNB27YHT3B3 packaging specification is not provided in available documentation. The substitute SPHWHAHDNG28YZT3D2 is supplied in Tray packaging. Packaging compatibility should be confirmed with procurement specifications.

Q: What is the impact of different test conditions on electrical parameters?

A: The main part specifies test current at 25°C, while the substitute specifies test current at 85°C. This temperature difference affects measured electrical characteristics. Forward voltage shows 0.9V reduction in the substitute, and lumens per watt efficiency differs (112 versus 134 lm/W), reflecting both generation differences and measurement condition variations.

Q: Are both components subject to the same export regulations?

A: Yes. Both components carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring equivalent export control and tariff treatment.

Q: What should be evaluated before implementing this substitution?

A: Mechanical fit verification against PCB layout and optical system constraints, electrical circuit compatibility confirmation with the higher maximum current rating (1.84A), forward voltage adjustment if applicable to driver circuits, and luminous flux output validation against application requirements.
