Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-A1-R250-000CB8 is determined by the following critical parameters:

Mechanical Compatibility: Package type (2-SMD Gull Wing), physical dimensions (5.00mm x 5.00mm), and mounting height (1.48mm max) must remain identical to ensure PCB layout compatibility without redesign.

Optical Compatibility: Color (White) and viewing angle (120°) must match the original specification.

Electrical Compatibility: Forward voltage (Vf), test current, and maximum current ratings determine circuit compatibility. Luminous flux output at specified test conditions establishes functional equivalence.

Environmental & Compliance: Moisture sensitivity level (MSL 2A), REACH status, and ECCN classification must be maintained for supply chain and regulatory consistency.

The MX6AWT-A1-R250-000CB3 shares identical mechanical, optical, and environmental parameters with the MX6SWT-A1-R250-000CB8, establishing it as a direct substitute within the XLamp® MX series family.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-A1-R250-000CB3 is the designated substitute for the obsolete MX6SWT-A1-R250-000CB8. Both components share identical mechanical dimensions, optical properties, thermal characteristics, and regulatory compliance status (REACH Unaffected, ECCN EAR99).

The substitute part carries Active product status, ensuring long-term availability and supply chain stability. The MX6AWT-A1-R250-000CB3 is RoHS Compliant, providing enhanced environmental compliance compared to the main part specification.

Electrical differences exist: the substitute operates at 3.3V forward voltage with 300mA test current, compared to the main part's 20V and 60mA. Both deliver identical luminous flux (104lm) at their respective test conditions. The substitute achieves higher luminous efficiency (105 lm/W versus 87 lm/W), with a higher maximum current rating (1A versus 175mA).

Circuit redesign is required to accommodate the different voltage and current characteristics. PCB layout remains compatible due to identical package geometry and mounting footprint.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-R250-000CB3 be used as a direct drop-in replacement without circuit modification?

A: No. While the mechanical footprint and optical properties are identical, the electrical characteristics differ significantly. The substitute operates at 3.3V with 300mA test current, whereas the main part operates at 20V with 60mA. Circuit redesign is required to accommodate these voltage and current differences.

Q: Are the physical dimensions and mounting characteristics identical?

A: Yes. Both components use 2-SMD Gull Wing packaging with identical dimensions (5.00mm x 5.00mm) and maximum seated height (1.48mm). PCB layout and assembly processes remain unchanged.

Q: What is the difference between the package designations "2-SMD, Gull Wing" and "2-SMD, Gull Wing Exposed Pad"?

A: The substitute includes an exposed pad for enhanced thermal management. Both packages maintain identical external dimensions and mounting compatibility.

Q: Does the substitute part meet the same environmental and regulatory requirements?

A: Yes. Both components share identical Moisture Sensitivity Level (MSL 2A, 4 Weeks), REACH status (REACH Unaffected), and ECCN classification (EAR99). The substitute additionally carries RoHS Compliance certification.

Q: What is the luminous flux equivalence between these parts?

A: Both components deliver 104lm (100lm ~ 107lm) at their respective test conditions. The substitute achieves this output at 300mA and 3.3V, while the main part achieves it at 60mA and 20V. Luminous efficiency differs: the substitute provides 105 lm/W compared to the main part's 87 lm/W.
