Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-A1-0000-000CB1 is based on the following allowable parameters:

• Color Match: White LED required
• Mounting Type: Surface Mount only
• Package Compatibility: 2-SMD, Gull Wing form factor with identical footprint (5.00mm x 5.00mm)
• Height Constraint: Maximum seated height of 0.058" (1.48mm)
• Thermal Resistance: 5°C/W package thermal resistance
• Viewing Angle: 120° viewing angle maintained
• Moisture Sensitivity: MSL 2A (4 Weeks) or better

The MX6AWT-A1-0000-000CB1 qualifies as a substitute based on matching color, mounting type, package form factor, physical dimensions, height, thermal resistance, viewing angle, and moisture sensitivity level. However, this substitute operates at significantly different electrical parameters (3.3V forward voltage, 300mA test current) compared to the original part.

Engineering Selection Recommendations

The MX6AWT-A1-0000-000CB1 is the identified substitute for the obsolete MX6SWT-A1-0000-000CB1 based on mechanical and thermal compatibility. The substitute part is Active status, ensuring continued availability and supply chain support.

Key considerations for selection:

• Electrical Redesign Required: The substitute operates at 3.3V forward voltage versus 20V on the original part. Circuit design modifications to the LED driver and power supply are necessary.
• Current Profile Change: Test current increases from 60mA to 300mA, requiring driver circuit recalibration.
• Compliance Advantage: The substitute is RoHS Compliant, providing regulatory compliance benefits not specified for the original part.
• Thermal Performance: Both parts maintain identical thermal resistance (5°C/W) and physical dimensions, allowing direct footprint compatibility.
• Luminous Output: Both parts deliver equivalent flux output (104lm) at their respective test currents, with the substitute offering improved efficiency (105 lm/W versus 87 lm/W).

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000CB1 be used as a direct drop-in replacement for the MX6SWT-A1-0000-000CB1?

A: No. While both parts share identical physical dimensions, footprint, and thermal characteristics, the electrical parameters differ significantly. The substitute requires circuit redesign to accommodate the 3.3V forward voltage and 300mA test current specifications.

Q: Are the package dimensions identical between these two parts?

A: Yes. Both parts are 0.197" L x 0.197" W (5.00mm x 5.00mm) with a maximum seated height of 0.058" (1.48mm), allowing PCB footprint compatibility.

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

A: The substitute includes an exposed pad for enhanced thermal management. This does not affect electrical compatibility but may improve heat dissipation in the application.

Q: Does the substitute part meet RoHS requirements?

A: Yes. The MX6AWT-A1-0000-000CB1 is RoHS Compliant. The original part's RoHS status is not specified.

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

A: The original part packaging is not specified. The substitute is available in Tape & Reel (TR) format.
