Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-A1-R250-000EF4 is based on the following criteria derived from the provided parameters:

Matching Parameters:

• Color and CCT: White, Neutral 4750K
• Viewing Angle: 120°
• Mounting Type: Surface Mount
• Package Footprint: 5.00mm × 5.00mm
• Height: 1.48mm (maximum)
• Thermal Resistance: 5°C/W
• MSL Rating: 2A (4 Weeks)
• CRI: 75 (Typ)

Allowable Variations:

• Forward Voltage: Different operating voltage (3.3V vs. 20V) is acceptable when circuit design accommodates the change
• Test Current: Different test current (300mA vs. 60mA) reflects different operating point
• Flux Output: Variation within similar lumen range (111lm vs. 118lm)
• Lumens/Watt: Different efficiency at respective operating points (112 lm/W vs. 98 lm/W)
• Maximum Current: Higher maximum current rating (1A vs. 175mA) provides design flexibility
• Product Status: Active status preferred over obsolete for supply continuity

The identified substitute maintains identical physical dimensions, thermal characteristics, color specification, and viewing angle, enabling direct footprint compatibility with circuit redesign for voltage and current parameters.

Engineering Selection Recommendations

The MX6AWT-A1-R250-000DF4 is the identified substitute for the obsolete MX6SWT-A1-R250-000EF4. Selection of this alternative is supported by the following factors:

Product Status: The substitute is classified as 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 for electronic components in regulated markets.

Physical Compatibility: Identical footprint dimensions (5.00mm × 5.00mm), height (1.48mm), and thermal resistance (5°C/W) enable direct PCB layout reuse without modification.

Optical Specifications: Matching color temperature (4750K), CRI (75 Typ), and viewing angle (120°) ensure equivalent optical performance in the application.

Electrical Redesign Required: The substitute operates at 3.3V with 300mA test current versus the main part's 20V and 60mA. Circuit redesign is necessary to accommodate this voltage and current change. The higher maximum current rating (1A vs. 175mA) and improved efficiency (112 lm/W vs. 98 lm/W) at the substitute's operating point provide design flexibility.

Packaging: The substitute is supplied in Tape & Reel format, supporting automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-R250-000DF4 be used as a direct drop-in replacement without circuit modification?

A: No. While the physical footprint and thermal characteristics are identical, the substitute operates at 3.3V with 300mA test current compared to the main part's 20V and 60mA. The power supply and current-limiting circuitry must be redesigned to accommodate these electrical parameters.

Q: Are the optical characteristics identical between the main part and substitute?

A: Yes. Both parts are specified as White, Neutral 4750K with 75 CRI (Typ) and 120° viewing angle. Flux output is comparable: 118lm for the main part and 111lm for the substitute at their respective test currents.

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

A: The substitute includes an exposed pad for enhanced thermal management. Both packages maintain identical external dimensions and height, ensuring PCB footprint compatibility. The exposed pad on the substitute provides improved heat dissipation characteristics.

Q: Is the substitute RoHS compliant?

A: Yes. The MX6AWT-A1-R250-000DF4 is specified as RoHS Compliant. The main part's RoHS status is not provided in the available data.

Q: What is the impact of the different maximum current ratings (175mA vs. 1A)?

A: The substitute's higher maximum current rating (1A) provides greater design margin and flexibility for current management. This does not affect substitution compatibility; it reflects the different electrical architecture of the XLamp® MX-6 series compared to the MX-6S.

Q: Are both parts available in the same packaging format?

A: The substitute is supplied in Tape & Reel (TR) format. The main part's packaging format is not specified in the available data. Both are suitable for automated assembly processes.
