Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MX6SWT-H1-0000-000EA1 is determined by the following critical parameters:

• Color and Correlated Color Temperature (CCT): Both parts must be white with 5000K CCT to maintain identical light output characteristics
• Mounting Type and Package: Both parts must be surface mount with 2-SMD, Gull Wing configuration to ensure PCB compatibility
• Physical Dimensions: Both parts must share identical footprint (5.00mm x 5.00mm) and maximum seated height (1.48mm) for mechanical interchangeability
• Thermal Resistance: Both parts must maintain 5°C/W thermal resistance for equivalent thermal management
• Viewing Angle: Both parts must provide 120° viewing angle for consistent optical performance

The MX6AWT-A1-0000-000DA1 qualifies as a substitute based on these parameters. However, critical differences exist in electrical characteristics (forward voltage and test current) that require circuit design evaluation.

Engineering Selection Recommendations

The MX6AWT-A1-0000-000DA1 is the designated substitute for the obsolete MX6SWT-H1-0000-000EA1. Selection of this alternative is supported by the following factors:

• Product Status: The MX6AWT-A1-0000-000DA1 maintains Active status, ensuring long-term availability and supply chain continuity
• Compliance: The substitute part is RoHS Compliant, meeting current regulatory requirements
• Mechanical Compatibility: Identical footprint (5.00mm x 5.00mm) and seated height (1.48mm) enable direct PCB placement without layout modification
• Optical Performance: Both parts deliver equivalent 5000K cool white light with 120° viewing angle and comparable luminous flux (111lm vs. 118lm)
• Thermal Management: Identical 5°C/W thermal resistance maintains equivalent thermal performance

Circuit design modifications are required due to the significant difference in forward voltage (20V vs. 3.3V) and test current (60mA vs. 300mA). The substitute part operates at substantially lower voltage with proportionally higher current, necessitating driver circuit redesign and current limiting adjustments.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000DA1 be used as a direct drop-in replacement without circuit modification?

A: No. While the parts share identical physical dimensions and optical characteristics, the forward voltage differs significantly (20V vs. 3.3V). The driver circuit and current limiting resistors must be recalculated for the substitute part's 3.3V operating voltage and 300mA test current.

Q: What is the difference between the 2-SMD Gull Wing and 2-SMD Gull Wing Exposed Pad packages?

A: The MX6AWT-A1-0000-000DA1 includes an exposed thermal pad for enhanced heat dissipation. Both packages maintain identical external dimensions and footprint compatibility. The exposed pad provides improved thermal performance in high-power applications.

Q: Are there any compliance differences between the main part and substitute?

A: The MX6AWT-A1-0000-000DA1 is RoHS Compliant, while the MX6SWT-H1-0000-000EA1 does not specify RoHS status. Both parts are REACH Unaffected and classified as EAR99 for export control purposes.

Q: How do the luminous efficacy values compare?

A: The MX6AWT-A1-0000-000DA1 delivers 112 lm/W compared to 98 lm/W for the main part, representing a 14% improvement in luminous efficacy. This higher efficiency is achieved through the XLamp® MX-6 series design improvements.

Q: What is the impact of the different CRI values?

A: The main part specifies CRI 80, while the substitute provides CRI 75 (Typ). This 5-point difference may be perceptible in color-critical applications requiring high color rendering accuracy.

Q: Are both parts suitable for the same thermal environment?

A: Yes. Both parts maintain identical 5°C/W thermal resistance. However, the MX6AWT-A1-0000-000DA1's exposed pad provides additional thermal dissipation capability, making it suitable for higher ambient temperature applications.
