Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000B53 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Color and CCT: White, Cool 6000K (must match)
• Package / Case: 2-SMD, Gull Wing Exposed Pad (must match)
• Physical dimensions: 5.00 mm × 5.00 mm footprint (must match)
• Viewing Angle: 120° (must match)
• Mounting Type: Surface Mount (must match)

Functional Parameters (allowable variation):

• Forward Voltage (Vf): Substitute must be compatible with circuit design; different Vf values require circuit re-evaluation
• Test Current and Flux: Substitutes may have different current ratings and luminous output; selection depends on application requirements
• Lumens/Watt efficiency: Substitutes may vary; higher efficiency is generally acceptable
• CRI: Substitutes with matching or higher CRI are acceptable
• Thermal Resistance: Substitutes with equal or lower thermal resistance are acceptable
• Maximum Current: Substitutes with equal or higher maximum current rating are acceptable

The identified substitute MX3AWT-A1-0000-000C53 matches all mandatory compatibility criteria and is from the same manufacturer family (XLamp® MX-3 series).

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000C53 is a direct substitute for the obsolete MX3SWT-A1-0000-000B53 based on matching package geometry, color specification, CCT, viewing angle, and thermal characteristics. Both components are from CreeLED's XLamp® family and share identical physical footprints and mounting requirements.

Key Considerations:

The substitute operates at a significantly lower forward voltage (3.7V vs. 10.7V) and higher test current (350mA vs. 115mA). Circuit design modifications are required to accommodate this voltage and current difference. The substitute delivers higher luminous flux (104 lm vs. 97 lm) at comparable lumens-per-watt efficiency (80 vs. 79 lm/W).

The MX3AWT-A1-0000-000C53 carries Active product status and RoHS Compliance certification, providing assurance of ongoing availability and regulatory compliance for new designs. Both components maintain identical moisture sensitivity levels and thermal resistance specifications.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000C53 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000B53?

A: The components share identical package geometry, footprint, and mounting type, allowing physical installation in the same PCB location. However, the forward voltage difference (3.7V vs. 10.7V) requires circuit re-design of the LED driver or current-limiting circuit. Direct substitution without circuit modification will result in component failure or incorrect operation.

Q: What is the impact of the different forward voltage specifications?

A: The MX3AWT operates at 3.7V typical forward voltage compared to 10.7V for the MX3SWT. This represents a fundamental difference in the LED's internal structure and requires corresponding changes to power supply voltage, current-limiting resistor values, or driver circuit topology. Applications must be re-evaluated for compatibility.

Q: Are the color and brightness characteristics identical?

A: Both components are specified as Cool White 6000K with identical CRI values (75 Typ). The substitute delivers slightly higher luminous flux (104 lm vs. 97 lm) at comparable efficiency (80 vs. 79 lm/W), representing a minor brightness increase. Color temperature and rendering characteristics are equivalent.

Q: What are the packaging and moisture handling differences?

A: Both components use 2-SMD Gull Wing Exposed Pad packages with 5.00 mm × 5.00 mm footprints and identical moisture sensitivity levels (2A, 4 Weeks). The substitute is supplied in Tape & Reel packaging, while the main part packaging is not specified. Storage and handling procedures are equivalent.

Q: Why is the substitute listed as Active while the main part is Obsolete?

A: The MX3AWT-A1-0000-000C53 represents an active product line from CreeLED with ongoing manufacturing and availability. The MX3SWT-A1-0000-000B53 has reached end-of-life status. For new designs and production continuity, the Active substitute is the recommended component selection.

Q: Are there compliance or regulatory differences between the two parts?

A: The substitute carries explicit RoHS Compliance certification. Both components are REACH Unaffected and share identical ECCN (EAR99) and HTSUS classifications. The substitute's RoHS status provides additional regulatory assurance for applications subject to RoHS requirements.
