Substitute Part Grouping Explanation

Substitution of the Samsung LM231A LED is determined by strict alignment of the following critical parameters:

Color and CCT Matching: The substitute must operate at warm white 2700K to maintain identical color output and application compatibility.

Electrical Characteristics: Forward voltage (Vf) and test current must remain within acceptable operating ranges. The LM231A operates at 2.86V typical with 65mA test current. Substitute components must support equivalent electrical operation without requiring circuit redesign.

Luminous Output: Flux output at 25°C must remain within the specified range (20lm–30lm at 65mA test current) to ensure consistent brightness performance.

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

Package and Mounting: Surface-mount configuration is mandatory. Package dimensions and thermal characteristics must be compatible with existing PCB layouts and thermal management designs.

Compliance and Status: Substitute parts must maintain RoHS compliance and active or equivalent product status to ensure long-term supply chain viability and regulatory adherence.

The CreeLED XLamp® XH-G series component (XHGAWT-00-0000-00000HWE8) meets these substitution criteria.

Engineering Selection Recommendations

Electrical Compatibility: The CreeLED XLamp® XH-G substitute operates at 2.9V typical forward voltage compared to the Samsung LM231A at 2.86V. This 0.04V difference is within acceptable tolerance for most LED driver circuits and does not require circuit modification.

Luminous Performance: Both components deliver 25 lumens at 65mA test current with equivalent luminous efficacy (134 lm/W vs. 133 lm/W). Color rendering index remains constant at CRI 80, ensuring identical color fidelity in warm white applications.

Product Status and Supply: The Samsung LM231A is classified as obsolete, creating long-term supply risk. The CreeLED XLamp® XH-G is active product status, ensuring sustained availability and manufacturing support.

Compliance Certification: Both components are RoHS compliant and carry equivalent regulatory status (ECCN: EAR99, HTSUS: 8541.41.0000), maintaining compliance requirements across applications.

Physical Considerations: The CreeLED substitute uses a larger 1212 (3030 metric) package compared to the Samsung 0909 (2323 metric) package. The footprint increases from 2.30mm × 2.30mm to 3.00mm × 3.00mm, and height increases from 0.80mm to 1.83mm. PCB layout modification is required to accommodate the larger package dimensions. Existing 0909 footprints cannot directly accept the 3030 package without redesign.

Current Rating: The CreeLED XLamp® XH-G supports maximum current of 350mA compared to 150mA for the Samsung LM231A, providing additional operational headroom without affecting the 65mA test condition equivalence.

Viewing Angle: The substitute provides a 130° viewing angle compared to 120° for the original component, offering slightly wider light distribution without compromising application requirements.

Frequently Asked Questions (FAQ)

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

A: No. The CreeLED substitute uses a 1212 (3030 metric) package with dimensions of 3.00mm × 3.00mm, while the Samsung LM231A uses a 0909 (2323 metric) package of 2.30mm × 2.30mm. PCB footprint redesign is required. The height difference (1.83mm vs. 0.80mm) also affects clearance and thermal management considerations.

Q: Are the electrical characteristics compatible?

A: Yes. The forward voltage difference of 0.04V (2.9V vs. 2.86V) is within acceptable tolerance for standard LED driver circuits. Test current remains identical at 65mA. No circuit redesign is necessary for voltage compatibility.

Q: Will the luminous output remain the same?

A: Yes. Both components deliver 25 lumens at 65mA test current at 25°C. Luminous efficacy is equivalent (133–134 lm/W), and color rendering index remains at CRI 80 for identical warm white color output.

Q: What is the impact of the larger package size?

A: The 3030 package occupies a larger PCB footprint and has greater height. Applications with space constraints or existing 0909 footprints require PCB layout redesign. Thermal management may improve due to the larger package size and higher maximum current rating (350mA vs. 150mA).

Q: Is the CreeLED substitute suitable for long-term production?

A: Yes. The CreeLED XLamp® XH-G is active product status with established manufacturing support. The Samsung LM231A is obsolete, making the CreeLED substitute the appropriate choice for sustained production and supply chain continuity.

Q: Are compliance certifications equivalent?

A: Yes. Both components are RoHS compliant with identical regulatory classifications (ECCN: EAR99, HTSUS: 8541.41.0000). Compliance requirements are maintained with the substitute component.

Q: Does the wider viewing angle (130° vs. 120°) affect application compatibility?

A: No. The wider 130° viewing angle of the CreeLED substitute is compatible with applications designed for the 120° angle. The increased light distribution does not create incompatibility; it provides equivalent or improved performance for most lighting applications.

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

A: The CreeLED XLamp® XH-G is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. Verify packaging compatibility with your procurement and assembly requirements.
