Substitute Part Grouping Explanation

The MX6AWT-H1-0000-0009B6 is identified as a substitute for the MX6SWT-H1-0000-0009B6 based on the following allowable substitution parameters:

Mechanical Compatibility:

• Identical package type: 2-SMD, Gull Wing configuration
• Identical physical dimensions: 5.00mm x 5.00mm footprint
• Identical maximum seated height: 1.48mm
• Identical thermal resistance: 5°C/W
• Identical mounting type: Surface Mount

Optical Compatibility:

• Identical color: White
• Identical viewing angle: 120°
• Identical luminous flux output: 84lm at test current

Environmental & Compliance:

• Identical moisture sensitivity level: 2A (4 Weeks)
• Identical REACH status: REACH Unaffected
• Identical ECCN classification: EAR99
• Identical HTSUS code: 8541.41.0000

Critical Difference - Electrical Parameters: The substitute part operates at fundamentally different electrical parameters: 3.3V forward voltage at 300mA test current versus 20V at 60mA. This difference requires circuit redesign and is not a direct pin-compatible replacement without modification to the power supply and current-limiting circuitry.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-0000-0009B6 is an active product with current manufacturing status, providing supply chain continuity for the obsolete MX6SWT-H1-0000-0009B6. Both components share identical mechanical footprints, optical characteristics, and environmental compliance ratings, enabling PCB layout reuse without modification.

The substitute part carries RoHS Compliant certification, whereas the main part does not specify RoHS status. This represents an improvement in regulatory compliance for new designs.

Selection of the MX6AWT-H1-0000-0009B6 requires circuit redesign due to the 20V-to-3.3V forward voltage reduction and 60mA-to-300mA current increase. The power supply architecture and current-limiting resistor values must be recalculated. The substitute part delivers superior luminous efficacy at 85 lm/W compared to 70 lm/W, resulting in improved energy efficiency at the new operating point.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-0009B6 be used as a direct drop-in replacement without circuit modification?

A: No. The substitute part requires circuit redesign. The forward voltage differs by 16.7V (20V to 3.3V), and the test current increases from 60mA to 300mA. Power supply voltage and current-limiting circuitry must be recalculated for proper operation.

Q: Are the physical dimensions and PCB footprints identical?

A: Yes. Both parts use identical 5.00mm x 5.00mm footprints with 1.48mm maximum seated height in 2-SMD, Gull Wing configuration. PCB layouts are mechanically compatible without modification.

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

A: The substitute part includes an exposed pad for enhanced thermal management. This does not affect mechanical compatibility but provides improved heat dissipation characteristics.

Q: Do both parts meet the same environmental and compliance standards?

A: Both parts share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS codes (8541.41.0000). The substitute part specifies RoHS Compliance, whereas the main part does not specify RoHS status. Both maintain identical MSL rating of 2A (4 Weeks).

Q: What is the luminous flux output difference between the two parts?

A: Both parts deliver 84lm (81lm ~ 87lm) at their respective test currents. The substitute achieves this output at lower forward voltage with higher current, resulting in 85 lm/W efficiency versus 70 lm/W for the main part.

Q: Is the CRI (Color Rendering Index) specification available for the substitute part?

A: The substitute part MX6AWT-H1-0000-0009B6 does not specify a CRI value. The main part specifies CRI 80. Color rendering characteristics should be confirmed with the manufacturer if CRI performance is a design requirement.

Q: What is the maximum current rating for each part?

A: The main part MX6SWT-H1-0000-0009B6 has a maximum current rating of 175mA. The substitute part MX6AWT-H1-0000-0009B6 has a maximum current rating of 1A, providing greater current headroom in the new circuit design.
