Substitute Part Grouping Explanation

Substitution of the MX6SWT-H1-0000-000CB4 is based on the following critical parameters:

• Color: White (both parts match)
• Mounting Type: Surface Mount (both parts match)
• Package / Case: 2-SMD, Gull Wing configuration (both parts match)
• Physical Dimensions: 5.00mm x 5.00mm footprint (both parts match)
• Height - Seated (Max): 1.48mm (both parts match)
• Thermal Resistance of Package: 5°C/W (both parts match)
• Viewing Angle: 120° (both parts match)

The MX6AWT-H1-0000-000BB4 qualifies as a substitute based on identical mechanical compatibility and thermal characteristics. However, electrical parameters differ significantly: the substitute operates at 3.3V forward voltage with 300mA test current, compared to the original part's 20V and 60mA specifications. This electrical difference requires circuit redesign and is not a direct pin-for-pin replacement.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-0000-000BB4 is the documented substitute for the obsolete MX6SWT-H1-0000-000CB4. Selection of this substitute requires circuit redesign due to fundamental electrical parameter differences. The substitute operates at significantly lower forward voltage (3.3V vs. 20V) and higher test current (300mA vs. 60mA), necessitating modification of current-limiting resistors and power supply specifications.

The substitute part carries Active product status and RoHS compliance certification, providing advantages for long-term availability and regulatory adherence. Both parts share identical mechanical footprints, thermal characteristics, and viewing angles, enabling PCB layout reuse without modification.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000BB4 be used as a direct replacement without circuit modification?

A: No. The substitute part requires circuit redesign. The original part operates at 20V with 60mA test current, while the substitute operates at 3.3V with 300mA test current. Current-limiting resistors and power supply connections must be recalculated for the new electrical specifications.

Q: Are the physical dimensions identical between the main part and substitute?

A: Yes. Both parts share identical footprints (5.00mm x 5.00mm), height (1.48mm maximum seated height), and thermal resistance (5°C/W). PCB layouts require no modification for component placement.

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 are mechanically compatible with identical lead configurations and mounting requirements.

Q: Why is the original part classified as obsolete?

A: The MX6SWT-H1-0000-000CB4 is part of the XLamp® MX-6S series, which has been superseded by the active XLamp® MX-6 series. The substitute part represents the current production equivalent from CreeLED, Inc.

Q: Does the substitute part offer improved luminous efficacy?

A: Yes. The substitute delivers 98 lm/W compared to the original part's 87 lm/W at their respective test currents. Luminous flux output is comparable (97lm vs. 104lm), with the substitute providing higher efficiency per watt.

Q: Is the substitute part RoHS compliant?

A: Yes. The MX6AWT-H1-0000-000BB4 carries RoHS compliance certification. The original part's RoHS status is not specified in available documentation.
