LED LM231A WARM WHT 2700K 2323 (SPMWHT221MD5WAW0S0) - Equivalent & Substitute Parts

Part Overview

The Samsung Semiconductor LM231A warm white LED (SPMWHT221MD5WAW0S0) is a surface mount light emitting diode designed for general illumination applications requiring warm color temperature output at 2700K. 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 requirements for applications currently utilizing this component.

Substitute Part Grouping Explanation

Substitution of the Samsung LM231A (SPMWHT221MD5WAW0S0) is determined by the following critical parameters:

Primary Substitution Criteria:

• Color and Correlated Color Temperature (CCT): White, Warm 2700K (fixed requirement)
• Luminous Flux @ 25°C: 25 lumens nominal (20 - 30 lm range acceptable)
• Forward Voltage (Vf): 2.86V typical (electrical compatibility with existing driver circuits)
• Test Current: 65mA (operational current compatibility)
• Color Rendering Index (CRI): 80 (color quality consistency)
• Thermal Resistance: 20°C/W (thermal management equivalence)
• RoHS Compliance: Required for regulatory continuity

Secondary Compatibility Factors:

• Mounting Type: Surface Mount (PCB assembly process compatibility)
• Package dimensions and height (mechanical fit on existing PCBs)
• Maximum current rating (design margin consideration)
• Viewing angle (optical performance in application context)

The identified substitute part, CreeLED XLamp® XH-G (XHGAWT-00-0000-00000HWE8), meets all primary substitution criteria while operating in a larger 1212 (3030 metric) package format. This represents a functional equivalent with enhanced performance characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The CreeLED XLamp® XH-G (XHGAWT-00-0000-00000HWE8) is electrically and functionally equivalent to the Samsung LM231A for warm white LED applications at 2700K color temperature. Both components deliver 25 lumens at 65mA test current with identical CRI (80) and thermal resistance (20°C/W), ensuring equivalent optical and thermal performance in driver circuits designed for the original part.

Regulatory and Compliance Alignment:

Both the original and substitute parts maintain RoHS Compliance and REACH Unaffected status, ensuring continuity of regulatory requirements. Both are classified under ECCN EAR99 and HTSUS 8541.41.0000, supporting equivalent supply chain and export documentation procedures.

Product Status Advantage:

The substitute part carries Active product status, whereas the original LM231A is Obsolete. Selection of the XLamp® XH-G provides access to an actively manufactured component with ongoing manufacturer support and supply availability.

Physical Integration Considerations:

The substitute part operates in a larger 1212 (3030 metric) package (3.00 x 3.00 mm footprint, 1.83 mm height) compared to the original 0909 (2323 metric) package (2.30 x 2.30 mm footprint, 0.80 mm height). PCB layout modifications are required to accommodate the larger component footprint and increased height. Existing solder pad patterns and assembly fixtures must be evaluated for compatibility with the larger package dimensions.

Electrical Performance:

Forward voltage differs by 0.04V (2.86V original vs. 2.9V substitute), which is within typical LED manufacturing tolerances and compatible with standard LED driver circuits. The substitute part features a higher maximum current rating (350mA vs. 150mA), providing additional design margin for thermal and electrical stress management.

Frequently Asked Questions (FAQ)

Q1: Can the CreeLED XLamp® XH-G directly replace the Samsung LM231A on existing PCBs without modification?

A: No. The substitute part uses a larger 1212 (3030 metric) package versus the original 0909 (2323 metric) package. PCB layout modifications, including solder pad repositioning and trace routing adjustments, are required. The component height also increases from 0.80 mm to 1.83 mm, which may affect clearance in space-constrained applications.

Q2: Are the electrical characteristics compatible with existing LED driver circuits?

A: Yes. Both components operate at equivalent test currents (65mA), deliver identical luminous flux (25 lumens), and maintain the same thermal resistance (20°C/W). The forward voltage difference of 0.04V (2.86V vs. 2.9V) is within standard LED manufacturing tolerances and does not require driver circuit redesign for typical constant-current driver implementations.

Q3: Does the substitute part maintain the same color quality?

A: Yes. Both components are specified at 2700K warm white color temperature with CRI 80, ensuring identical color appearance and rendering characteristics in the application.

Q4: What is the viewing angle difference, and does it affect application performance?

A: The substitute part features a 130° viewing angle compared to the original 120° angle. This represents a 10° wider light distribution, which may alter optical performance in applications with specific beam angle requirements. Optical design validation is recommended for applications where viewing angle is a critical parameter.

Q5: Are there supply chain advantages to using the substitute part?

A: Yes. The CreeLED XLamp® XH-G carries Active product status with ongoing manufacturer support, whereas the Samsung LM231A is Obsolete. The substitute part provides access to current production inventory and long-term supply continuity.

Q6: Do both parts comply with environmental and export regulations?

A: Yes. Both components are RoHS Compliant, REACH Unaffected, and classified as EAR99 under export control regulations. Regulatory documentation and supply chain procedures remain equivalent.

Q7: What is the maximum current rating difference, and how does it affect design considerations?

A: The substitute part supports 350mA maximum current versus 150mA for the original part. This higher rating provides additional thermal and electrical design margin. However, operation at the specified 65mA test current remains identical for both components.
