LED XLamp® MX-3S White SMD MX3SWT-A1-0000-000AB2

Part Overview

The CreeLED MX3SWT-A1-0000-000AB2 is a white LED XLamp® MX-3S surface mount device designed for lighting applications. This component delivers 91 lumens at 115mA test current with a forward voltage of 10.7V and 120° viewing angle. The part is classified as obsolete, making identification of compatible alternatives essential for ongoing production and maintenance applications. Substitute parts must maintain equivalent optical output, mechanical form factor, and thermal characteristics while accommodating different electrical operating parameters.

Key Parameters

Substitute Part Grouping Explanation

The MX3AWT-A1-0000-000AB2 qualifies as a substitute based on the following criteria:

Mechanical Compatibility: Both parts share identical package geometry (2-SMD, Gull Wing Exposed Pad), physical dimensions (5.00 mm × 5.00 mm), and seated height (1.48 mm), ensuring PCB layout compatibility without redesign.

Optical Equivalence: Both parts deliver 91 lumens at their respective test currents and maintain the same 120° viewing angle, providing equivalent light output and distribution characteristics.

Thermal Characteristics: Identical thermal resistance (11°C/W) ensures equivalent thermal management performance in the application circuit.

Substitution Limitation: The MX3AWT operates at 3.7V forward voltage and 350mA test current, compared to the MX3SWT's 10.7V and 115mA. This represents a fundamentally different electrical operating point. Substitution requires circuit redesign to accommodate the lower voltage and higher current requirements. Direct pin-for-pin replacement without circuit modification is not possible.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000AB2 is the documented substitute for the obsolete MX3SWT-A1-0000-000AB2. Both parts are manufactured by CreeLED, Inc., and share identical mechanical, optical, and thermal specifications. The MX3AWT holds active product status and carries RoHS compliance certification, providing supply continuity and regulatory alignment for new designs.

Substitution requires modification of the LED drive circuit to accommodate the different electrical operating point. The MX3AWT's 3.7V forward voltage and 350mA test current necessitate redesign of the current-limiting resistor network and power supply voltage selection. Thermal management and PCB layout remain unchanged due to identical package geometry and thermal resistance.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000AB2 be used as a direct replacement without circuit modification?

A: No. While both parts share identical package geometry, dimensions, and thermal characteristics, they operate at different electrical parameters. The MX3AWT requires 3.7V forward voltage compared to the MX3SWT's 10.7V, and draws 350mA at test current versus 115mA. The LED drive circuit must be redesigned to accommodate these differences.

Q: Are the optical outputs equivalent?

A: Yes. Both parts deliver 91 lumens at their respective test currents and maintain 120° viewing angle, providing equivalent light output and distribution for the application.

Q: What are the mechanical compatibility considerations?

A: Both parts use identical 2-SMD, Gull Wing Exposed Pad packaging with 5.00 mm × 5.00 mm dimensions and 1.48 mm seated height. No PCB layout modifications are required for component placement.

Q: Does the MX3AWT offer better supply availability?

A: Yes. The MX3AWT holds active product status, whereas the MX3SWT is obsolete. The MX3AWT also carries RoHS compliance certification, supporting regulatory requirements for new production.

Q: How do thermal characteristics compare?

A: Both parts have identical thermal resistance of 11°C/W, ensuring equivalent thermal management performance when properly mounted on the PCB.

Q: What is the impact on power consumption?

A: At test current, the MX3SWT dissipates approximately 1.23W (10.7V × 115mA), while the MX3AWT dissipates approximately 1.30W (3.7V × 350mA). The MX3AWT exhibits slightly higher power consumption at equivalent light output.
