Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWHT223MD5WATHS0 is based on the following critical parameters:

Color and Correlated Color Temperature (CCT): Both the main part and substitute maintain neutral white 4000K specification, ensuring consistent color output in lighting applications.

Viewing Angle: The 120° viewing angle is preserved across the substitute, maintaining beam distribution characteristics.

Mounting Type: Surface-mount technology is consistent, allowing direct PCB integration without modification.

CRI (Color Rendering Index): Both parts maintain an 80 CRI rating, ensuring equivalent color rendering performance.

RoHS Compliance: The substitute meets RoHS3 compliance, satisfying environmental and regulatory requirements.

The EAPL2835WA5 substitute operates at different electrical parameters (3.25V forward voltage, 60mA test current) and utilizes a different package form (1411/3528 Metric), but maintains functional equivalence through matching color, CCT, viewing angle, and CRI specifications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SPMWHT223MD5WATHS0 is classified as obsolete, while the EAPL2835WA5 maintains active product status. This distinction is critical for long-term supply chain planning and component availability.

Compliance and Certification: Both parts satisfy EAR99 export classification and HTSUS code 8541.41.0000. The EAPL2835WA5 meets ROHS3 compliance, representing current environmental standards, whereas the main part meets RoHS compliance.

Electrical Parameter Differences: The substitute operates at a higher forward voltage (3.25V versus 2.86V) and lower maximum current rating (75mA versus 150mA). Circuit design modifications may be required to accommodate these electrical differences.

Package Footprint Differences: The substitute utilizes a larger 1411 (3528 Metric) package compared to the 0909 (2323 Metric) main part. PCB layout redesign is necessary for physical accommodation.

Thermal Characteristics: The main part exhibits superior thermal performance with 20°C/W thermal resistance compared to the substitute's 50°C/W rating. Thermal management considerations apply when selecting the substitute.

Luminous Output: Both parts deliver comparable luminous flux at their respective test currents (29lm and 27lm), with overlapping tolerance ranges ensuring functional equivalence in lighting applications.

Frequently Asked Questions (FAQ)

Q: Can the EAPL2835WA5 directly replace the SPMWHT223MD5WATHS0 without circuit modifications?

A: No. The substitute requires circuit design changes due to different forward voltage (3.25V versus 2.86V) and maximum current specifications (75mA versus 150mA). Current-limiting resistor values and power supply considerations must be recalculated.

Q: Are the color and brightness characteristics identical between these parts?

A: Both parts maintain neutral white 4000K color temperature and 80 CRI rating. Luminous flux values are comparable (29lm and 27lm respectively), ensuring equivalent brightness performance within specified tolerance ranges.

Q: What are the physical accommodation requirements for substitution?

A: The EAPL2835WA5 uses a larger package (3.50mm x 2.80mm versus 2.30mm x 2.30mm). PCB footprint redesign is mandatory. The height difference is minimal (0.85mm versus 0.80mm) and typically accommodates standard assembly clearances.

Q: Do both parts meet current environmental compliance standards?

A: The EAPL2835WA5 meets ROHS3 compliance, representing current environmental standards. The main part meets RoHS compliance. Both satisfy EAR99 export classification requirements.

Q: What is the significance of the different thermal resistance ratings?

A: The main part's 20°C/W thermal resistance provides superior heat dissipation compared to the substitute's 50°C/W rating. Applications with stringent thermal requirements may experience different junction temperature performance.

Q: Are the moisture sensitivity levels compatible for storage and handling?

A: The main part carries MSL 2A (4 Weeks) while the substitute carries MSL 3 (168 Hours). The substitute requires more frequent baking cycles during storage. Different moisture control procedures apply during manufacturing and assembly.

Q: Why is the main part classified as obsolete?

A: Obsolescence reflects Samsung Semiconductor's discontinuation of the LM231B series. The EAPL2835WA5 represents an active alternative from Everlight Electronics, ensuring ongoing component availability for new designs and production continuity.
