LED XLamp® MX-3S MX3SWT-A1-0000-000DA2 Equivalent & Substitute Parts

Part Overview

The CreeLED MX3SWT-A1-0000-000DA2 is an XLamp® MX-3S neutral white LED (4750K) designed for surface mount applications requiring 10.7V forward voltage at 115mA test current. This part is classified as obsolete, making substitute part identification critical for ongoing production and maintenance applications. The XLamp® MX-3S series has been superseded by newer generations within the XLamp® product line, necessitating evaluation of compatible alternatives that maintain functional equivalence while meeting current availability and compliance requirements.

Substitute Part Grouping Explanation

Substitution of the obsolete MX3SWT-A1-0000-000DA2 is evaluated based on the following critical parameters that determine functional compatibility:

Electrical Compatibility Criteria:

• Color and correlated color temperature (CCT): Both parts must be neutral white 4750K to maintain color consistency in the application
• Luminous flux output: Substitute must deliver equivalent light output (111 lm nominal) to preserve system brightness performance
• Viewing angle: Both parts maintain 120° viewing angle for consistent light distribution
• CRI: Both parts maintain 75 (Typ) color rendering index

Mechanical & Thermal Compatibility Criteria:

• Package type: Both parts use 2-SMD, Gull Wing Exposed Pad configuration, enabling direct PCB footprint compatibility
• Physical dimensions: Both parts measure 5.00 mm × 5.00 mm, ensuring identical mounting envelope
• Height: Both parts maintain 1.48 mm seated height for consistent assembly clearance
• Thermal resistance: Substitute thermal performance (5°C/W) is superior to the original (11°C/W), providing improved thermal management

Electrical Operating Point Differences: The substitute part operates at significantly different voltage and current levels (3.3V @ 300mA vs. 10.7V @ 115mA). This fundamental difference requires circuit redesign and is not a direct pin-compatible replacement. The substitute is suitable only for applications where the power supply and current-limiting circuitry can be adapted to the lower voltage requirement.

Engineering Selection Recommendations

The MX6AWT-A1-0000-000DF4 is an active product with current manufacturing status and RoHS compliance, addressing the obsolescence of the MX3SWT-A1-0000-000DA2. Both parts share identical color temperature (4750K neutral white), luminous flux output (111 lm), CRI (75 Typ), viewing angle (120°), and physical package dimensions (5.00 mm × 5.00 mm, 1.48 mm height).

The substitute part offers improved thermal performance (5°C/W vs. 11°C/W), reducing junction temperature rise in thermal-constrained applications. However, the significant difference in electrical operating point (3.3V @ 300mA vs. 10.7V @ 115mA) requires complete redesign of the power supply and current-limiting circuitry. Direct PCB footprint compatibility exists due to identical package geometry, but electrical circuit modifications are mandatory.

Selection of the MX6AWT-A1-0000-000DF4 is appropriate for new designs or redesigned applications where the lower voltage requirement can be accommodated. For applications requiring minimal circuit modification, alternative XLamp® series parts with voltage characteristics closer to 10.7V should be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000DF4 be used as a direct replacement without circuit modification?

A: No. While both parts share identical package geometry (5.00 mm × 5.00 mm, 2-SMD Gull Wing), the forward voltage differs significantly (3.3V vs. 10.7V). The power supply and current-limiting circuitry must be redesigned to accommodate the lower voltage requirement. Direct substitution without circuit modification will result in component failure or inadequate light output.

Q: Are the physical dimensions identical between the two parts?

A: Yes. Both the MX3SWT-A1-0000-000DA2 and MX6AWT-A1-0000-000DF4 measure 5.00 mm × 5.00 mm with a maximum seated height of 1.48 mm. PCB footprint compatibility is confirmed, and no mechanical redesign is required.

Q: What is the difference in light output between these parts?

A: Both parts deliver 111 lm (107–114 lm range) at their respective test currents. The MX6AWT-A1-0000-000DF4 achieves higher efficiency (112 lm/W vs. 90 lm/W) due to its lower voltage operation, but absolute luminous flux output is equivalent.

Q: Does the MX6AWT-A1-0000-000DF4 meet RoHS compliance?

A: Yes. The MX6AWT-A1-0000-000DF4 is RoHS Compliant. The original MX3SWT-A1-0000-000DA2 RoHS status is not specified in the available data.

Q: What is the thermal advantage of the substitute part?

A: The MX6AWT-A1-0000-000DF4 has thermal resistance of 5°C/W compared to 11°C/W for the original part. This 55% reduction in thermal resistance results in lower junction temperature rise for the same power dissipation, improving reliability and light output stability in thermally constrained applications.

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

A: The MX6AWT-A1-0000-000DF4 is supplied in Tape & Reel (TR) format. The original part packaging format is not specified. Verify packaging requirements for your procurement and assembly processes.
