LED LM231A WARM WHT 2700K 2323 (SPMWHT221MD5WAWMS0) - Equivalent & Substitute Parts

Part Overview

The Samsung Semiconductor LM231A warm white LED (SPMWHT221MD5WAWMS0) is a surface-mount light-emitting diode designed for warm white lighting applications at 2700K 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 has reached obsolete product status. Identifying equivalent substitute components is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this LED specification.

Substitute Part Grouping Explanation

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

Substitution Criteria:

• Color specification: White, Warm
• Correlated color temperature: 2700K
• Luminous flux @ 25°C at test current: 25 lm (acceptable range 20–30 lm)
• Test current: 65 mA
• Forward voltage (typical): within ±0.1V of 2.86V
• Color Rendering Index (CRI): 80 or higher
• Mounting type: Surface Mount
• Regulatory compliance: RoHS Compliant, REACH Unaffected

The CreeLED XLamp® XH-G series component (XHGAWT-00-0000-00000HWE8) meets all substitution criteria. While the package size differs (1212/3030 metric versus 0909/2323 metric), the electrical performance parameters, color characteristics, and regulatory compliance align with the original specification. Package size variation requires PCB layout verification but does not affect electrical compatibility at the component level.

Parameter Comparison

Engineering Selection Recommendations

Electrical Compatibility: The CreeLED XLamp® XH-G (XHGAWT-00-0000-00000HWE8) demonstrates electrical compatibility with the Samsung LM231A specification. Forward voltage variance of +0.04V (2.86V to 2.9V) is within acceptable tolerance for LED circuit design. Luminous flux output at test current (65 mA) is equivalent at 25 lumens. Both components operate at identical color temperature (2700K) and CRI (80), ensuring consistent color rendering in warm white lighting applications.

Regulatory and Compliance Status: Both components maintain RoHS Compliant certification and REACH Unaffected status, satisfying regulatory requirements for electronic component procurement in regulated markets. The substitute component carries active product status, ensuring long-term availability and supply chain stability compared to the obsolete LM231A series.

Physical Integration Considerations: The CreeLED substitute utilizes a larger package footprint (3030 metric versus 2323 metric) and increased seated height (1.83mm versus 0.80mm). PCB layout modification is required to accommodate the larger component dimensions. Viewing angle increases from 120° to 130°, which may affect optical system design in applications with specific beam angle requirements.

Current Rating: The substitute component supports maximum current of 350 mA compared to 150 mA for the original part. This higher rating provides design margin for future application requirements without component replacement.

Frequently Asked Questions (FAQ)

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

A: Electrical substitution is direct at the component level. Forward voltage variance (+0.04V) and identical test current (65 mA) require no circuit redesign. However, PCB layout modification is mandatory due to package size difference (2323 to 3030 metric). Verify PCB clearance and thermal management provisions before implementation.

Q: What is the impact of the larger package size on thermal performance?

A: Both components specify identical thermal resistance (20°C/W). The larger 3030 package provides increased surface area, potentially improving thermal dissipation. Verify thermal management design for the specific application to ensure junction temperature remains within acceptable limits.

Q: Are there any optical performance differences between these components?

A: Color temperature (2700K) and CRI (80) are identical, ensuring equivalent color rendering. Viewing angle increases from 120° to 130°, providing wider light distribution. Applications requiring specific beam angles must evaluate this variance against optical system design requirements.

Q: What packaging format is available for the CreeLED substitute?

A: The CreeLED XLamp® XH-G is supplied in Tape & Reel (TR) format. Verify compatibility with assembly equipment and handling procedures. The original Samsung component packaging format was not specified in available documentation.

Q: Is the higher maximum current rating (350 mA versus 150 mA) a concern?

A: The higher maximum current rating does not present a concern. The component is operated at identical test current (65 mA) in equivalent applications. The higher rating provides design margin and does not affect performance at specified operating conditions.

Q: What is the moisture sensitivity level for the substitute component?

A: Moisture sensitivity level (MSL) for the CreeLED substitute was not provided in available technical documentation. Verify MSL classification with the component supplier to ensure proper storage and handling procedures align with manufacturing requirements.

Q: Can both components be used interchangeably in existing designs?

A: Electrical interchangeability is confirmed. Physical interchangeability requires PCB redesign to accommodate the larger 3030 package footprint and increased height. Evaluate design constraints, assembly capabilities, and thermal management before component selection.
