Substitute Part Grouping Explanation

The MX3AWT-A1-0000-000DA1 is identified as a substitute for the MX3SWT-A1-0000-000CA1 based on the following substitution criteria:

Matching Parameters:

• Manufacturer: CreeLED, Inc.
• Color / CCT: White, Cool / 5000K
• CRI: 75 (Typ)
• Viewing Angle: 120°
• Package / Case: 2-SMD, Gull Wing Exposed Pad
• Size / Dimension: 0.197" L x 0.197" W (5.00mm x 5.00mm)
• Height - Seated (Max): 0.058" (1.48mm)
• Thermal Resistance: 11°C/W
• Mounting Type: Surface Mount
• Moisture Sensitivity Level (MSL): 2A (4 Weeks)

Differing Parameters: The substitute part operates at different electrical specifications (3.7V forward voltage, 350mA test current) and belongs to the XLamp® MX-3 series rather than MX-3S. These differences require circuit design evaluation for compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000DA1 is an active product with RoHS compliance, providing regulatory advantage over the obsolete MX3SWT-A1-0000-000CA1. Both components share identical mechanical footprints, thermal characteristics, and optical properties (color temperature, CRI, viewing angle).

The primary consideration for substitution is the electrical specification difference: the substitute operates at 3.7V forward voltage and 350mA test current compared to the main part's 10.7V and 115mA. This requires circuit redesign to accommodate the lower voltage and higher current requirements. The substitute delivers comparable luminous flux (111lm vs. 104lm) with similar efficiency (86 lm/W vs. 85 lm/W).

Selection of the MX3AWT-A1-0000-000DA1 is appropriate for new designs or redesigns where the electrical specifications can be accommodated. For applications requiring the exact electrical characteristics of the MX3SWT-A1-0000-000CA1, alternative sources or design modifications must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000DA1 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000CA1?

A: No. While both components share identical mechanical footprints and optical properties, the electrical specifications differ significantly. The substitute requires a different power supply voltage (3.7V vs. 10.7V) and operates at higher current (350mA vs. 115mA). Circuit redesign is necessary.

Q: Are the package dimensions identical between these two parts?

A: Yes. Both the MX3SWT-A1-0000-000CA1 and MX3AWT-A1-0000-000DA1 use the same 2-SMD, Gull Wing Exposed Pad package with dimensions of 0.197" L x 0.197" W (5.00mm x 5.00mm) and maximum seated height of 0.058" (1.48mm). PCB layout compatibility is maintained.

Q: What is the primary advantage of the MX3AWT-A1-0000-000DA1 over the main part?

A: The substitute is an active product with RoHS compliance, ensuring long-term availability and regulatory compliance. The obsolete status of the main part makes the substitute the preferred choice for new production.

Q: Do both parts have the same color temperature and CRI?

A: Yes. Both components are cool white LEDs at 5000K with a CRI of 75 (Typ), ensuring identical color characteristics and rendering properties.

Q: What is the thermal resistance of these components?

A: Both parts have a thermal resistance of 11°C/W, providing identical thermal management characteristics in circuit design.
