Key Parameters

Substitute Part Grouping Explanation

The substitute part MLCAWT-A1-0000-000WE7 (CreeLED XLamp® ML-C series) is evaluated as a functional equivalent based on the following electrical and mechanical compatibility parameters:

Common Specification Criteria:

• Color and CCT rating: Both parts are warm white LEDs at 3000K
• CRI (Color Rendering Index): Both rated at 80, ensuring comparable color accuracy
• Viewing angle: Both parts provide 120° viewing angle
• Flux output @ 25°C: Both rated at 25lm (within overlapping ranges)
• RoHS Compliance: Both parts meet RoHS requirements
• MSL Rating: Both parts carry 2A (4 Weeks) moisture sensitivity level
• ECCN Classification: Both parts classified as EAR99
• Mounting type: Both utilize surface mount technology

Allowable Substitution Parameters: The substitute part demonstrates compatibility through matching photometric (luminous flux, color temperature, CRI) and environmental compliance specifications. Variations in forward voltage (2.86V vs. 3.2V), test current (65mA vs. 100mA), package footprint (2323 vs. 4-SMD), and thermal resistance are technical differences that must be evaluated within specific circuit design requirements.

Parameter Comparison

Engineering Selection Recommendations

The MLCAWT-A1-0000-000WE7 qualifies as a substitute for the obsolete SPMWHT223MD5WAV0S0 based on alignment of color temperature, CRI rating, viewing angle, and luminous flux specifications. Both parts maintain identical RoHS compliance, MSL ratings, and regulatory classifications (EAR99, HTSUS 8541.41.0000), ensuring regulatory continuity in applications requiring these certifications.

Selection of the CreeLED substitute requires circuit-level design review to accommodate the electrical parameter differences: the higher forward voltage (3.2V vs. 2.86V) and increased test current (100mA vs. 65mA) necessitate driver circuit adjustment. The larger physical footprint (3.50mm x 3.15mm vs. 2.30mm x 2.30mm) and increased height (1.33mm vs. 0.80mm) require PCB layout re-evaluation. The superior thermal resistance of the substitute (13°C/W vs. 20°C/W) provides improved thermal management in applications where thermal dissipation is a limiting factor.

The active product status of the CreeLED component ensures ongoing supply chain availability, addressing the supply continuity risk presented by the obsolete Samsung part.

Frequently Asked Questions (FAQ)

Q: What makes the MLCAWT-A1-0000-000WE7 a substitute for the SPMWHT223MD5WAV0S0?

A: Both parts satisfy the same photometric and color specifications: warm white LEDs at 3000K, 25 lumens at 25°C operation, 80 CRI rating, and 120° viewing angle. Both carry identical RoHS compliance, MSL ratings, and export classifications, enabling regulatory continuity in replacement applications.

Q: Can I directly replace the Samsung part with the CreeLED part without circuit modification?

A: No. The forward voltage difference (2.86V vs. 3.2V) and test current difference (65mA vs. 100mA) require driver circuit recalculation to maintain correct operating current and voltage. PCB layout changes are also necessary due to the larger package footprint.

Q: How do the package dimensions affect the substitution?

A: The Samsung part (0909 / 2323 Metric) measures 2.30mm x 2.30mm with 0.80mm height. The CreeLED substitute (4-SMD) measures 3.50mm x 3.15mm with 1.33mm height. PCB designs originally accommodating the smaller Samsung package require footprint modification and clearance verification for the larger CreeLED component.

Q: Are there supply availability differences between these parts?

A: The Samsung SPMWHT223MD5WAV0S0 carries obsolete product status, indicating discontinued manufacture and diminishing supply availability. The CreeLED MLCAWT-A1-0000-000WE7 maintains active product status with ongoing manufacturer support and inventory.

Q: Do both parts meet the same environmental compliance standards?

A: Yes. Both parts are RoHS Compliant and carry identical MSL (2A / 4 Weeks) and export classification ratings (EAR99, HTSUS 8541.41.0000). Regulatory documentation requirements are identical for applications subject to these compliance standards.
