Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000DDZ is based on the following criteria:

Matching Parameters:

• Color and CCT: White, Cool 5000K
• Flux output: 111 lm (107–114 lm range) at 25°C
• CRI: 75 (Typ)
• Viewing angle: 120°
• Package type: 2-SMD, Gull Wing Exposed Pad
• Physical dimensions: 5.00mm × 5.00mm footprint
• Height: 1.48mm (Seated, Max)
• Mounting type: Surface Mount

Allowable Variations:

• Forward voltage (Vf) and test current may differ due to different LED series architecture
• Lumens/Watt efficiency may vary
• Thermal resistance may differ
• Maximum current rating may differ
• Product status and compliance certifications may differ

The MX6AWT-A1-0000-000DDZ qualifies as a substitute based on matching optical output, color specification, CRI, viewing angle, and identical physical package dimensions and mounting footprint.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-A1-0000-000DDZ is a direct substitute for the obsolete MX3SWT-A1-0000-000DDZ based on identical optical performance (111 lm at 5000K, 75 CRI), matching viewing angle (120°), and identical physical package footprint (5.00mm × 5.00mm, 1.48mm height).

Key Considerations:

• Electrical Interface: The MX6AWT operates at 3.3V with 300mA test current, compared to 10.7V at 115mA for the MX3SWT. Circuit design must accommodate this voltage and current difference.
• Thermal Performance: The MX6AWT exhibits superior thermal characteristics (5°C/W vs. 11°C/W), reducing thermal management requirements.
• Product Status: The MX6AWT is active production, ensuring long-term availability and supply chain stability.
• Compliance: The MX6AWT carries RoHS Compliant certification, meeting modern regulatory requirements.
• Efficiency: The MX6AWT delivers higher lumens/watt efficiency (112 lm/W vs. 90 lm/W).

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000DDZ be used as a direct drop-in replacement for the MX3SWT-A1-0000-000DDZ?

A: The MX6AWT matches the MX3SWT in optical output, color, CRI, viewing angle, and physical package dimensions. However, the forward voltage (3.3V vs. 10.7V) and test current (300mA vs. 115mA) differ significantly. Circuit redesign is required to accommodate the different electrical operating point.

Q: Are the package footprints identical?

A: Yes. Both parts use a 2-SMD, Gull Wing Exposed Pad package with 5.00mm × 5.00mm footprint and 1.48mm seated height. PCB layout compatibility is maintained.

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

A: The MX6AWT operates at 3.3V (Typ) versus 10.7V (Typ) for the MX3SWT. Power supply and current-limiting circuit design must be adjusted accordingly. The MX6AWT requires a lower voltage source or different circuit topology.

Q: Does the MX6AWT provide equivalent light output?

A: Yes. Both parts deliver 111 lumens (107–114 lm range) at their respective test currents and 25°C. Optical performance is equivalent.

Q: What are the moisture sensitivity requirements?

A: Both parts carry MSL 2A (4 Weeks) classification. Identical moisture handling and storage protocols apply.

Q: Is the MX6AWT RoHS compliant?

A: Yes. The MX6AWT is RoHS Compliant. RoHS status for the MX3SWT is not specified in available documentation.
