LED LM231A COOL WHITE 6500K 2323 (SPMWHT221MD5WAPKS0) - Equivalent & Substitute Parts

Part Overview

The Samsung Semiconductor LM231A is a surface-mount LED lighting component featuring cool white 6500K color temperature in a compact 0909 (2323 metric) package. This part is classified as obsolete, making identification of functionally equivalent substitute components essential for ongoing design support and procurement continuity. The LM231A delivers 26 lumens at 25°C under 65mA test current with a forward voltage of 2.86V and 120° viewing angle, suitable for applications requiring cool white illumination with standard color rendering characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete Samsung LM231A is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Color and correlated color temperature (CCT): White, Cool 6500K
• Test current: 65 mA nominal operation
• Forward voltage range: Compatible with 2.86V nominal (tolerance: ±0.1V acceptable)
• Color Rendering Index (CRI): 80 minimum
• Viewing angle: 120° or greater
• Thermal resistance: 20°C/W or lower
• RoHS compliance: Required
• Mounting type: Surface mount

Secondary Compatibility Factors:

• Package footprint: 0909 (2323 metric) or larger compatible footprint
• Maximum current rating: 150 mA or higher
• Lumens/Watt efficiency: 140 lm/W or higher preferred
• Moisture sensitivity level: 2A or better

The CreeLED XLamp® XH-G series component XHGAWT-00-0000-00000HXE1 meets all primary substitution criteria and exceeds several secondary factors, establishing it as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The CreeLED XLamp® XH-G (XHGAWT-00-0000-00000HXE1) is a functional equivalent for the obsolete Samsung LM231A based on electrical parameter alignment. Both components operate at identical test current (65 mA), matching color temperature (6500K), and equivalent CRI (80). Forward voltage differential of 0.04V is within acceptable tolerance for standard LED circuit designs.

Design Considerations:

The primary design constraint is the package footprint change from 0909 (2323 metric) to 1212 (3030 metric). The substitute component is 0.70 mm larger in both length and width, and 1.03 mm taller. PCB layout modifications are required to accommodate the larger footprint and increased height profile. Thermal management characteristics remain equivalent at 20°C/W.

Compliance Status:

Both components maintain RoHS compliance and equivalent regulatory classification (ECCN: EAR99, HTSUS: 8541.41.0000). The substitute part is currently in active production status with established supply chain availability (31,764 units in stock versus 785 units for the obsolete original).

Performance Advantages:

The substitute delivers 3 lumens higher output (29 lm vs. 26 lm) at identical test current, resulting in 10% higher luminous efficiency (154 lm/W vs. 140 lm/W). Maximum current rating increases from 150 mA to 350 mA, providing design flexibility for higher-brightness applications. Viewing angle expands from 120° to 130°.

Frequently Asked Questions (FAQ)

Q: Can the CreeLED XLamp® XH-G directly replace the Samsung LM231A without circuit modification?

A: Electrical substitution is direct. The 0.04V forward voltage difference (2.86V to 2.9V) is within standard LED circuit tolerance and requires no circuit redesign. However, PCB layout modification is mandatory due to package size change from 2323 to 3030 metric.

Q: What are the physical constraints of using the larger 3030 package?

A: The substitute component occupies 0.70 mm additional space in both X and Y dimensions (2.30 mm to 3.00 mm) and extends 1.03 mm higher (0.80 mm to 1.83 mm). Verify PCB clearance, solder reflow profile compatibility, and mechanical assembly constraints before implementation.

Q: Are there thermal management differences between the two components?

A: Thermal resistance is identical at 20°C/W for both parts. However, the larger 3030 package may provide improved thermal coupling to PCB copper areas. Verify thermal simulation for your specific application if operating near maximum current ratings.

Q: Does the higher luminous output of the substitute affect circuit design?

A: At identical 65 mA test current, the 3 lumen increase (26 lm to 29 lm) is proportional and does not require circuit modification. If brightness increase is undesirable, current can be reduced proportionally. Maximum current rating increases to 350 mA, allowing higher brightness operation if needed.

Q: What is the impact of the wider 130° viewing angle?

A: The 10° wider viewing angle (120° to 130°) provides broader light distribution. This is beneficial for general illumination applications and does not negatively impact focused-beam designs. Verify optical performance in your specific application geometry.

Q: Are there supply chain or lead time advantages to the substitute?

A: The CreeLED XLamp® XH-G is in active production with 31,764 units currently in stock, compared to 785 units for the obsolete Samsung LM231A. Long-term availability and standard lead times are established for the substitute.

Q: What packaging format is available for the substitute?

A: The CreeLED component is supplied in Tape & Reel (TR) format, standard for high-volume surface-mount assembly. Verify compatibility with your pick-and-place equipment and reel specifications.

Q: Are there any compliance or regulatory differences?

A: Both components share identical regulatory classification (ECCN: EAR99, HTSUS: 8541.41.0000) and maintain RoHS compliance. No additional compliance documentation is required for substitution.
