Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-A1-0000-000FE4 is determined by the following critical parameters:

• Color and CCT: Both main and substitute parts must be White, Neutral 4500K to maintain color consistency in the application
• Viewing Angle: 120° is maintained across all parts
• Package Type: 2-SMD, Gull Wing configuration with identical 5.00mm × 5.00mm footprint and 1.48mm maximum height
• Thermal Resistance: 5°C/W thermal performance is consistent
• Moisture Sensitivity: MSL 2A rating applies to all parts
• Mounting Type: Surface Mount compatibility is required

The substitute part MX6AWT-A1-0000-000DE4 shares the same physical footprint, color specification, and thermal characteristics. However, it operates at significantly different electrical parameters (3.3V forward voltage, 300mA test current) and belongs to the XLamp® MX-6 series rather than MX-6S. This part is active in production status, providing design continuity for applications where the electrical operating point can be accommodated.

Parameter Comparison

Engineering Selection Recommendations

The MX6SWT-A1-0000-000FE4 is obsolete, necessitating alternative component selection for new designs or production restocking.

MX6AWT-A1-0000-000DE4 is the designated substitute and offers the following advantages:

• Active Production Status: Ensures long-term availability and supply chain stability
• RoHS Compliance: Meets environmental and regulatory requirements; the main part does not specify RoHS status
• Identical Physical Footprint: 5.00mm × 5.00mm with 1.48mm maximum height allows direct PCB layout compatibility
• Matching Color and CRI: White, Neutral 4500K with CRI 75 maintains color consistency
• Tape & Reel Packaging: Supports automated assembly processes

Critical Design Consideration: The substitute part operates at 3.3V forward voltage and 300mA test current, compared to the main part's 20V and 60mA. Circuit design modifications are required to accommodate this electrical difference. The substitute delivers 111 lumens at its test current versus 126 lumens for the main part, representing a 12% reduction in absolute flux output. However, the substitute achieves 112 lm/W efficiency compared to 105 lm/W, indicating superior power efficiency.

Frequently Asked Questions (FAQ)

Q: Can MX6AWT-A1-0000-000DE4 be used as a direct drop-in replacement for MX6SWT-A1-0000-000FE4?

A: No. While both parts share identical physical dimensions (5.00mm × 5.00mm footprint, 1.48mm height) and color specification (White, Neutral 4500K), they have fundamentally different electrical operating points. The main part requires 20V forward voltage at 60mA, while the substitute operates at 3.3V and 300mA. Circuit redesign is necessary to accommodate these differences.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on: color and CCT matching (White, Neutral 4500K), viewing angle (120°), package type (2-SMD, Gull Wing), physical footprint (5.00mm × 5.00mm), maximum height (1.48mm), thermal resistance (5°C/W), and moisture sensitivity rating (MSL 2A). Electrical parameters (forward voltage, test current, maximum current) are application-dependent and do not prevent substitution if circuit design accommodates the differences.

Q: Why does the substitute part have an exposed pad in its package designation?

A: The MX6AWT-A1-0000-000DE4 features a 2-SMD, Gull Wing Exposed Pad configuration, which provides enhanced thermal management through direct contact with the PCB. This is beneficial for high-current applications (up to 1A maximum) and improves heat dissipation compared to the standard Gull Wing package.

Q: Is the substitute part RoHS compliant?

A: Yes. The MX6AWT-A1-0000-000DE4 is RoHS Compliant. The main part (MX6SWT-A1-0000-000FE4) does not specify RoHS status. For applications requiring RoHS compliance, the substitute part meets this requirement.

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

A: The main part delivers 126 lumens at 60mA and 25°C. The substitute delivers 111 lumens at 300mA and 25°C. This represents approximately 12% lower absolute flux output. However, the substitute achieves superior efficiency at 112 lm/W versus 105 lm/W for the main part.

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

A: No. The main part is supplied in bulk packaging, while the substitute is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes and provides better handling and traceability.
