Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MX3SWT-A1-0000-000CE3 is based on the following criteria derived from the provided parameters:

Mandatory Matching Parameters:

• Color and CCT: White, Cool 5000K
• Package Type: 2-SMD, Gull Wing Exposed Pad
• Physical Dimensions: 5.00 mm × 5.00 mm footprint
• Viewing Angle: 120°
• Thermal Resistance: 11°C/W
• Manufacturer: CreeLED, Inc.

Allowable Variation Parameters:

• Forward Voltage (Vf): Different operating voltage acceptable if circuit design accommodates
• Test Current and Maximum Current: Different current ratings acceptable if within circuit design limits
• Flux Output: Variation within lumen range acceptable based on application requirements
• Lumens/Watt Efficiency: Higher efficiency acceptable
• Product Status: Active status preferred for long-term availability

The substitute part MX3AWT-A1-0000-000DDZ meets all mandatory matching criteria while offering active product status and improved specifications.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000DDZ is a direct substitute for the obsolete MX3SWT-A1-0000-000CE3 based on identical package geometry, thermal characteristics, and optical properties (color, CCT, viewing angle, CRI).

Key Considerations:

• Product Status: The substitute is active, ensuring long-term availability and supply chain continuity compared to the obsolete main part.
• Compliance: The substitute carries RoHS Compliant certification, meeting current regulatory requirements.
• Electrical Differences: The substitute operates at 3.7V typical forward voltage versus 10.7V for the main part. Circuit design must accommodate this voltage difference. The substitute requires 350mA test current versus 115mA for the main part.
• Optical Performance: Both parts deliver equivalent luminous output (104 lm vs. 111 lm) and efficiency (85 lm/W vs. 86 lm/W) at their respective test currents.
• Physical Compatibility: Identical footprint, height, and thermal resistance ensure mechanical and thermal compatibility in existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can MX3AWT-A1-0000-000DDZ directly replace MX3SWT-A1-0000-000CE3 in existing designs?

A: Physical and thermal compatibility is confirmed. However, the forward voltage difference (3.7V vs. 10.7V) requires circuit redesign. The substitute cannot be used without modifying the power supply or current-limiting circuit.

Q: What are the key differences between these parts?

A: The main differences are forward voltage (3.7V vs. 10.7V), test current (350mA vs. 115mA), and product status (active vs. obsolete). Optical characteristics (color, CCT, viewing angle, CRI) and package dimensions are identical.

Q: Are the parts mechanically interchangeable?

A: Yes. Both parts use identical 2-SMD, Gull Wing Exposed Pad packaging with 5.00 mm × 5.00 mm footprint and 1.48 mm maximum height. PCB layout and reflow profiles remain unchanged.

Q: Does the substitute meet current compliance standards?

A: The substitute is RoHS Compliant. Both parts carry REACH Unaffected and EAR99 ECCN classifications.

Q: What is the impact of different test currents on brightness?

A: The substitute delivers 111 lumens at 350mA versus 104 lumens at 115mA for the main part. Brightness comparison requires evaluation at equivalent operating currents within each part's rated range.
