MX6SWT-H1-0000-000DF7 Equivalent & Substitute Parts

Part Overview

The MX6SWT-H1-0000-000DF7 is a CreeLED XLamp® MX-6S warm white LED (3200K) designed for surface mount applications requiring high color rendering index (CRI 80) and efficient light output. This part operates at 20V forward voltage with a test current of 60mA, delivering 111 lumens at 25°C with a luminous efficacy of 93 lm/W. The component features a 120° viewing angle and is housed in a 2-SMD Gull Wing package measuring 5.00mm × 5.00mm.

The MX6SWT-H1-0000-000DF7 is classified as Obsolete. Equivalent substitute parts are necessary for ongoing production, maintenance, and new design implementations where this original component is no longer available from primary sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-H1-0000-000DF7 is determined by the following critical parameters:

Color and Correlated Color Temperature (CCT): Both the main part and substitute must maintain White, Warm 3200K specification to ensure consistent color output in lighting applications.

Viewing Angle: The 120° viewing angle is a fixed optical characteristic that must be preserved across substitute parts.

Package Type and Dimensions: The 2-SMD Gull Wing package with 5.00mm × 5.00mm footprint and 1.48mm maximum seated height ensures mechanical and thermal compatibility with existing PCB layouts and assembly processes.

Thermal Resistance: The 5°C/W thermal resistance specification must be maintained to ensure equivalent thermal performance in the application.

Moisture Sensitivity Level (MSL): The 2A (4 Weeks) MSL classification must be matched to maintain consistent handling and storage requirements.

Regulatory Compliance: REACH Unaffected status ensures equivalent environmental compliance.

The MX6AWT-H1-0000-000BF7 qualifies as a functional equivalent based on these parameters. However, the substitute operates at significantly different electrical characteristics (3.3V forward voltage, 300mA test current) and therefore requires circuit redesign and validation for direct replacement in existing applications.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-0000-000BF7 is the designated substitute for the obsolete MX6SWT-H1-0000-000DF7. Both components are manufactured by CreeLED, Inc., and share identical color temperature (3200K), CRI (80), viewing angle (120°), package footprint (5.00mm × 5.00mm), and thermal characteristics (5°C/W).

The substitute part carries Active product status, ensuring ongoing availability and supply chain continuity. The MX6AWT-H1-0000-000BF7 is RoHS Compliant, providing enhanced environmental compliance compared to the main part specification.

Critical design consideration: The MX6AWT-H1-0000-000BF7 operates at 3.3V forward voltage with 300mA test current, compared to the main part's 20V and 60mA specifications. This represents a fundamental change in electrical operating point. Direct pin-for-pin replacement is not possible without complete circuit redesign, including power supply modification, current limiting resistor recalculation, and thermal management reassessment.

The substitute delivers 97 lumens at 25°C (compared to 111 lumens for the main part), representing approximately 12.6% lower light output. Luminous efficacy improves to 98 lm/W from 93 lm/W due to the lower operating voltage.

Selection of the MX6AWT-H1-0000-000BF7 is appropriate for new designs or redesigned applications where the electrical characteristics align with system requirements. For legacy applications requiring exact electrical compatibility, alternative sources or design modifications must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000BF7 be used as a direct replacement for the MX6SWT-H1-0000-000DF7 in existing designs?

A: No. While both components share identical color temperature, CRI, viewing angle, and package dimensions, the substitute operates at fundamentally different electrical parameters (3.3V vs. 20V forward voltage; 300mA vs. 60mA test current). Direct substitution requires complete circuit redesign and validation.

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

A: Substitution is determined by: color and CCT (3200K warm white), viewing angle (120°), package type and footprint (2-SMD Gull Wing, 5.00mm × 5.00mm), maximum seated height (1.48mm), thermal resistance (5°C/W), MSL classification (2A, 4 Weeks), and regulatory compliance (REACH Unaffected).

Q: How does the light output differ between these parts?

A: The MX6SWT-H1-0000-000DF7 produces 111 lumens at 25°C and 60mA test current. The MX6AWT-H1-0000-000BF7 produces 97 lumens at 25°C and 300mA test current, representing approximately 12.6% lower output. However, the substitute achieves higher luminous efficacy (98 lm/W vs. 93 lm/W) due to lower operating voltage.

Q: What is the significance of the "Exposed Pad" designation in the substitute part package?

A: The MX6AWT-H1-0000-000BF7 features an exposed pad in its 2-SMD Gull Wing package, which provides enhanced thermal dissipation compared to the standard Gull Wing package of the main part. This improves heat transfer to the PCB and supports higher current operation (1A maximum vs. 175mA maximum).

Q: Are there any compliance differences between the main part and substitute?

A: The MX6AWT-H1-0000-000BF7 is explicitly RoHS Compliant, while the main part specification does not include RoHS status. Both parts maintain REACH Unaffected status and identical MSL classification (2A, 4 Weeks).

Q: What inventory status should be considered for procurement?

A: The main part (MX6SWT-H1-0000-000DF7) is Obsolete with 880 pieces in stock. The substitute (MX6AWT-H1-0000-000BF7) is Active with 1107 pieces in stock, ensuring long-term availability for new production and design implementations.
