LED LM231A WARM WHT 3000K 2323 (SPMWHT221MD5WAV0S0) Equivalent & Substitute Parts

Part Overview

The Samsung Semiconductor LM231A warm white LED (SPMWHT221MD5WAV0S0) is a surface-mount light-emitting diode designed for warm white lighting applications at 3000K color temperature. This component operates at 2.86V forward voltage with a test current of 65mA, delivering 25 lumens at 25°C with a 120° viewing angle in a compact 0909 (2323 metric) package.

The LM231A series is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for applications utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Samsung LM231A warm white LED are identified based on strict alignment with the following critical parameters:

Color and CCT Match: Substitute parts must operate at warm white 3000K color temperature to maintain identical color rendering in the application.

Optical Output: Substitute parts must deliver approximately 25 lumens at the specified test current (65 mA) at 25°C, with acceptable tolerance ranges (20–30 lm).

Electrical Characteristics: Forward voltage (Vf) and test current must be compatible with existing circuit designs. Acceptable variation is limited to the operating range of the original design.

Luminous Efficiency: Lumens per watt performance must be comparable to support equivalent power consumption profiles.

Color Rendering Index (CRI): CRI of 80 or higher is required to maintain color fidelity in warm white applications.

Viewing Angle: Substitute parts with viewing angles of 120° or greater are acceptable, as wider angles provide equal or superior light distribution.

Package and Mounting: Surface-mount packages in 0909 (2323 metric) or compatible larger formats (such as 1212/3030 metric) are acceptable if PCB layout permits the dimensional change.

Compliance and Status: Substitute parts must maintain RoHS compliance and active or current product status to ensure long-term availability and regulatory alignment.

The CreeLED XLamp® XH-G series part XHGAWT-00-0000-00000HWE7 meets these substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Electrical Compatibility):

The CreeLED XLamp® XH-G (XHGAWT-00-0000-00000HWE7) is electrically compatible with the Samsung LM231A. Both components operate at identical test current (65 mA), deliver equivalent luminous flux (25 lm), and maintain the same color temperature (3000K) and CRI (80). The forward voltage difference of 0.04V is negligible in standard LED driver circuits. The substitute's higher maximum current rating (350 mA vs. 150 mA) does not affect operation at the specified 65 mA test current and provides additional design margin.

For PCB Layout Considerations:

The CreeLED substitute uses a larger 1212 (3030 metric) package compared to the original 0909 (2323 metric) package. The footprint increases from 2.30 mm × 2.30 mm to 3.00 mm × 3.00 mm, and the seated height increases from 0.80 mm to 1.83 mm. PCB layout modifications are required to accommodate the larger component. Verify that the increased height does not create clearance conflicts with adjacent components or enclosure constraints.

For Supply Chain and Compliance:

The Samsung LM231A is classified as obsolete, while the CreeLED XLamp® XH-G is an active product. The substitute ensures long-term availability, ongoing manufacturer support, and continued compliance with RoHS and REACH regulations. Both components share identical export classification (EAR99) and tariff codes (8541.41.0000).

For Optical Performance:

The substitute provides a wider viewing angle (130° vs. 120°), which may improve light distribution in applications where a broader beam is beneficial. Luminous efficiency is equivalent (133 lm/W vs. 134 lm/W), ensuring comparable power consumption.

Frequently Asked Questions (FAQ)

Q1: Can the CreeLED XLamp® XH-G (XHGAWT-00-0000-00000HWE7) be used as a direct drop-in replacement for the Samsung LM231A (SPMWHT221MD5WAV0S0)?

A: Electrical compatibility is confirmed. Both components operate at 65 mA test current, deliver 25 lumens at 3000K, and maintain CRI 80. However, the substitute uses a larger package (3030 metric vs. 2323 metric). PCB layout modifications are required to accommodate the increased footprint (2.30 mm to 3.00 mm) and height (0.80 mm to 1.83 mm). Verify that your PCB design permits these dimensional changes before implementation.

Q2: What is the impact of the 0.04V forward voltage difference (2.86V vs. 2.9V)?

A: The difference is negligible. Standard LED driver circuits and current-limiting designs operate across this voltage range without performance degradation. Both components fall within the typical operating envelope of industrial LED drivers and power supply designs.

Q3: Why is the substitute part larger in package size?

A: The CreeLED XLamp® XH-G series uses a 1212 (3030 metric) package, which is a larger format than the original 0909 (2323 metric) package. Larger packages typically offer improved thermal management and higher current handling capability. The substitute's maximum current rating of 350 mA (vs. 150 mA for the original) reflects this design advantage, though both operate identically at the specified 65 mA test current.

Q4: Are there any compliance or regulatory differences between the two parts?

A: No. Both components are RoHS compliant, REACH unaffected, and classified under identical export (EAR99) and tariff (8541.41.0000) codes. Regulatory requirements are fully aligned.

Q5: What is the viewing angle difference, and does it affect application compatibility?

A: The substitute provides a 130° viewing angle compared to the original 120°. This represents a 10° wider beam spread, which improves light distribution in applications requiring broader illumination. This is a performance enhancement and does not create compatibility issues.

Q6: How does the thermal resistance compare?

A: Both components have identical thermal resistance of 20°C/W. Thermal management performance is equivalent.

Q7: Is the substitute part actively manufactured?

A: Yes. The CreeLED XLamp® XH-G is classified as an active product, ensuring ongoing availability, manufacturer support, and compliance updates. The original Samsung LM231A is obsolete and no longer manufactured.

Q8: What inventory is available for each part?

A: The Samsung LM231A has 1110 pieces in stock. The CreeLED substitute has 824 pieces in stock. Both are available as new original components.
