Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SPMWHT223MD5WARMS0 is determined by the following critical parameters:

Primary Matching Criteria:

• Color specification: White, Cool white at 5000K color temperature
• Luminous flux range: Minimum 21 lumens at 25°C to maintain brightness performance
• Viewing angle: 120° to preserve optical characteristics
• Surface mount technology: Required for PCB assembly compatibility
• Compliance: RoHS Compliant status for regulatory alignment

Secondary Compatibility Factors:

• Forward voltage tolerance: 2.86V nominal (substitutes within 3.3V acceptable for circuit redesign)
• Maximum current rating: Minimum 150mA to support existing drive current specifications
• Thermal resistance: Package thermal performance within 20-25°C/W range
• Moisture sensitivity: MSL 2A classification for storage and handling consistency

The CreeLED MLBAWT-A1-0000-000WE3 qualifies as a functional substitute based on matching color temperature, luminous flux output, viewing angle, surface mount configuration, and compliance certifications. Package geometry differences require PCB layout verification.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The CreeLED MLBAWT-A1-0000-000WE3 is an active product substitute for the obsolete Samsung LM231B SPMWHT223MD5WARMS0. Both components meet the core functional requirements: 5000K cool white color temperature, 120° viewing angle, surface mount configuration, and RoHS compliance.

Design Considerations:

1. Forward Voltage Adjustment: The substitute operates at 3.3V typical versus 2.86V for the original part. Circuit drive electronics require recalibration to accommodate the 0.44V increase in forward voltage drop.

2. Package Geometry: The CreeLED component measures 3.50mm x 3.15mm with 1.33mm seated height, compared to the original 2.30mm x 2.30mm with 0.80mm height. PCB footprint and clearance verification is mandatory before implementation.

3. Test Current Differential: The substitute operates at 80mA test current versus 65mA for the original. Luminous flux output (27 lm vs. 26 lm) remains comparable, but power consumption increases proportionally.

4. Thermal Performance: Thermal resistance increases from 20°C/W to 25°C/W. Thermal management design review is required for applications with constrained thermal budgets.

5. Color Rendering Index: CRI decreases from 80 to 75 typical. Applications requiring high color accuracy should evaluate visual impact.

6. Active Product Status: The CreeLED XLamp® ML-B series maintains active manufacturing status, ensuring long-term availability and supply chain continuity.

Compliance Alignment:

Both components maintain RoHS Compliant certification and MSL 2A moisture sensitivity classification, supporting equivalent handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the CreeLED MLBAWT-A1-0000-000WE3 directly replace the Samsung LM231B in existing designs?

A: Direct PCB footprint replacement is not possible due to package geometry differences. The CreeLED component requires new PCB layout with adjusted footprint dimensions (3.50mm x 3.15mm vs. 2.30mm x 2.30mm). Forward voltage adjustment from 2.86V to 3.3V necessitates circuit redesign for the LED drive circuit.

Q: What is the impact of the 0.44V forward voltage increase?

A: The higher forward voltage increases voltage drop across the LED. Series resistor values or current-limiting circuit parameters must be recalculated to maintain proper current regulation. Power supply voltage requirements may increase depending on circuit topology.

Q: Are the luminous flux outputs equivalent?

A: Yes. The CreeLED substitute produces 27 lumens at 25°C (24-31 lm range) compared to 26 lumens (21-31 lm range) for the original Samsung part. Both fall within acceptable brightness specifications for equivalent optical performance.

Q: Does the larger package size affect thermal performance?

A: The CreeLED component has higher thermal resistance (25°C/W vs. 20°C/W). In thermally constrained applications, junction temperature will be approximately 5°C higher under identical ambient conditions. Thermal design review is recommended for high-power or high-ambient-temperature applications.

Q: Is the lower CRI (75 vs. 80) significant?

A: CRI difference of 5 points represents a minor reduction in color rendering capability. For general illumination applications, this difference is typically imperceptible. Color-critical applications (retail, photography, medical) should conduct visual evaluation.

Q: What are the compliance and supply chain advantages of the substitute?

A: The CreeLED MLBAWT-A1-0000-000WE3 maintains active product status with established manufacturing and distribution channels. RoHS Compliant and MSL 2A certifications align with the original part, supporting equivalent procurement and handling procedures.

Q: Can both parts be used interchangeably in inventory?

A: No. Due to package geometry, forward voltage, and test current differences, these components require separate inventory management and distinct circuit implementations. Mixed inventory usage is not recommended.
