LED LM231A COOL WHITE 5000K 2323 (SPMWHT221MD5WARMS0) - Equivalent & Substitute Parts

Part Overview

The SPMWHT221MD5WARMS0 is a surface-mount LED lighting component manufactured by Samsung Semiconductor, Inc., featuring cool white 5000K color temperature in the LM231A series. This component delivers 26 lumens at 25°C under 65mA test current with a forward voltage of 2.86V and 120° viewing angle in a compact 0909 (2323 metric) package.

The product status is listed as Obsolete, making identification of functionally equivalent substitute components necessary for ongoing design requirements, production continuity, and inventory management. Substitute parts must maintain compatibility across critical electrical parameters, thermal characteristics, and compliance certifications while accommodating potential package size variations in board layout.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the SPMWHT221MD5WARMS0 are identified based on strict alignment with the following critical parameters:

Color and Correlated Color Temperature (CCT): The substitute must operate at cool white 5000K to maintain color consistency in lighting applications.

Luminous Flux Performance: At the standard 65mA test current and 25°C ambient temperature, the substitute must deliver luminous flux within or near the 21-31 lumen range established for the original component.

Electrical Characteristics: Forward voltage (Vf) and maximum current ratings must be compatible with existing circuit designs. The test current of 65mA establishes the baseline operating point.

Color Rendering Index (CRI): A CRI value of 80 or higher ensures acceptable color rendering quality for general lighting applications.

Thermal Properties: Thermal resistance of 20°C/W or lower ensures adequate heat dissipation under normal operating conditions.

Compliance and Certifications: RoHS compliance and REACH unaffected status are mandatory for regulatory adherence.

Package Considerations: While the original component uses a 0909 (2323 metric) package, substitute parts may utilize larger packages (such as 1212/3030 metric) provided the PCB layout accommodates the increased footprint and the mounting type remains surface mount.

Engineering Selection Recommendations

The XHGAWT-00-0000-00000HXE3 (CreeLED XLamp XH-G) is a functionally equivalent substitute for the obsolete SPMWHT221MD5WARMS0 (Samsung LM231A) based on the following engineering criteria:

Electrical Compatibility: Both components operate at identical test current (65mA) with forward voltages of 2.86V and 2.9V respectively, representing a negligible 0.04V difference acceptable in standard LED circuit designs. Luminous flux output at 25°C is 26 lm versus 29 lm, both within the acceptable performance envelope for cool white 5000K lighting applications.

Optical and Color Characteristics: Both components deliver identical color temperature (5000K) and color rendering index (80), ensuring consistent color appearance and rendering quality in end-use applications.

Thermal Performance: Thermal resistance is identical at 20°C/W, maintaining equivalent heat dissipation characteristics.

Regulatory Compliance: Both components are RoHS compliant and REACH unaffected, satisfying regulatory requirements for electronics manufacturing and distribution.

Product Status Advantage: The substitute component carries Active product status, ensuring ongoing availability and manufacturing support, whereas the original component is Obsolete.

Physical Package Consideration: The substitute utilizes a larger 1212 (3030 metric) package compared to the original 0909 (2323 metric) package. PCB layout modification is required to accommodate the increased footprint (3.00mm x 3.00mm versus 2.30mm x 2.30mm) and increased height (1.83mm versus 0.80mm). This represents the primary design consideration for implementation.

Performance Enhancement: The substitute delivers superior luminous efficiency at 154 lm/W compared to 140 lm/W, and supports higher maximum current (350mA versus 150mA), providing design flexibility for future applications.

Frequently Asked Questions (FAQ)

Q: Can the XHGAWT-00-0000-00000HXE3 directly replace the SPMWHT221MD5WARMS0 without circuit modification?

A: Electrical substitution is direct. The forward voltage difference (2.9V versus 2.86V) is negligible for standard LED driver circuits. However, PCB layout modification is required due to the larger package size (3030 metric versus 2323 metric). Verify that the PCB footprint and clearances accommodate the 3.00mm x 3.00mm component dimensions and 1.83mm maximum height.

Q: Are the luminous flux outputs compatible?

A: Yes. The original component delivers 26 lm at 65mA test current (21-31 lm range), while the substitute delivers 29 lm at the same test current (27-31 lm range). Both values fall within acceptable performance parameters for cool white 5000K lighting applications.

Q: What is the impact of the wider viewing angle (130° versus 120°)?

A: The substitute offers a 10° wider beam distribution angle. This results in broader light distribution and lower peak intensity in the forward direction. Verify that the application's optical design accommodates this wider beam pattern.

Q: Does the larger package size affect thermal performance?

A: No. Both components maintain identical thermal resistance of 20°C/W. The larger package does not compromise heat dissipation characteristics.

Q: Are both components compliant with regulatory requirements?

A: Yes. Both the original and substitute components are RoHS compliant and REACH unaffected, meeting regulatory requirements for electronics manufacturing and distribution.

Q: What is the significance of the substitute's higher maximum current rating (350mA versus 150mA)?

A: The substitute supports operation at significantly higher current levels, providing design flexibility for future applications requiring increased light output. However, the standard test current remains 65mA for both components.

Q: Is the substitute available in the same packaging format?

A: The substitute is supplied in Tape & Reel (TR) format, which is standard for high-volume production. The original component packaging format was not specified in the available data.

Q: What is the primary design consideration for implementing this substitute?

A: PCB layout modification is the primary consideration. The substitute's larger footprint (3.00mm x 3.00mm) and increased height (1.83mm) require verification that the PCB design accommodates these dimensions and that no component clearance conflicts exist.
