MX3SWT-A1-0000-000CE5 Equivalent & Substitute Parts

Part Overview

The MX3SWT-A1-0000-000CE5 is a CreeLED XLamp® MX-3S neutral white LED (4000K) designed for surface mount applications. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance requirements. The MX-3S series has been superseded by newer XLamp® generations, requiring careful parameter matching for direct substitution in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000CE5 is based on the following critical parameters:

Electrical Compatibility:

• Color and CCT matching (White, Neutral 4000K)
• CRI (Color Rendering Index) of 80 (Typ)
• Viewing angle of 120°
• Package type (2-SMD, Gull Wing Exposed Pad)
• Physical dimensions (5.00mm x 5.00mm footprint)
• Height compatibility (1.48mm seated height)

Operational Considerations:

• Forward voltage and current characteristics must be evaluated for circuit compatibility
• Thermal resistance affects thermal management in the application
• MSL rating and moisture sensitivity requirements

The MX6AWT-A1-0000-000CE5 meets the core substitution criteria for color, CCT, CRI, viewing angle, and physical package specifications. However, significant differences exist in electrical parameters (forward voltage and test current), requiring circuit design review.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-A1-0000-000CE5 is the active substitute for the obsolete MX3SWT-A1-0000-000CE5. Both parts share identical color temperature (4000K), CRI (80 Typ), viewing angle (120°), and physical package dimensions (5.00mm x 5.00mm, 1.48mm height).

Key Differences Requiring Design Review:

The MX6AWT operates at significantly lower forward voltage (3.3V vs. 10.7V) and higher test current (300mA vs. 115mA). These electrical differences necessitate circuit redesign, particularly in current-limiting and voltage regulation stages. The MX6 series demonstrates improved thermal performance (5°C/W vs. 11°C/W) and higher luminous efficacy (105 lm/W vs. 85 lm/W).

The MX6AWT-A1-0000-000CE5 carries active product status and RoHS compliance certification, supporting long-term supply chain continuity and regulatory requirements. Both parts maintain identical MSL ratings (2A, 4 Weeks) for moisture sensitivity handling.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000CE5 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000CE5?

A: No. While both parts share identical physical package dimensions, color temperature, CRI, and viewing angle, the forward voltage differs significantly (3.3V vs. 10.7V). Direct substitution without circuit modification will result in incorrect LED operation or failure. The power supply and current-limiting circuitry must be redesigned for the MX6 series electrical characteristics.

Q: Are the package footprints identical?

A: Yes. Both parts use 2-SMD, Gull Wing Exposed Pad packages with 5.00mm x 5.00mm footprints and 1.48mm maximum seated height. PCB layout and reflow profiles remain compatible.

Q: What is the impact of the different forward voltages?

A: The MX3SWT operates at 10.7V (Typ) while the MX6AWT operates at 3.3V (Typ). This 7.4V difference requires complete redesign of the LED driver circuit, including voltage regulation and current limiting stages. Existing power supply designs for the MX3 series cannot be directly applied to the MX6 series.

Q: Does the MX6AWT provide better performance?

A: The MX6AWT demonstrates higher luminous efficacy (105 lm/W vs. 85 lm/W) and superior thermal performance (5°C/W vs. 11°C/W). Both parts deliver identical flux output (104lm) at their respective test currents, but the MX6 achieves this with improved efficiency and thermal management.

Q: What are the compliance and supply chain advantages of the MX6AWT?

A: The MX6AWT-A1-0000-000CE5 carries active product status with RoHS compliance certification, ensuring long-term availability and regulatory alignment. The obsolete MX3SWT status limits future supply and support options.

Q: Are moisture sensitivity requirements the same?

A: Yes. Both parts carry MSL 2A ratings (4 Weeks), requiring identical moisture handling, storage, and reflow procedures.
