MX3SWT-A1-0000-000AE6 Equivalent & Substitute Parts

Part Overview

The MX3SWT-A1-0000-000AE6 is a CreeLED XLamp® MX-3S warm white LED (3500K) in a 2-SMD surface mount package with exposed pad. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The MX-3S series has been superseded by newer generations within the XLamp product line, requiring careful parameter matching for direct replacement in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000AE6 is determined by the following critical parameters:

• Color and Correlated Color Temperature (CCT): Both parts must be warm white at 3500K to maintain color consistency in the application.
• Package and Mechanical Compatibility: Both parts use 2-SMD, Gull Wing Exposed Pad in 5.00mm × 5.00mm footprint with 1.48mm maximum seated height, ensuring PCB layout compatibility.
• Viewing Angle: Both parts maintain 120° viewing angle for consistent light distribution.
• Thermal Resistance: Both parts share 11°C/W thermal resistance, supporting equivalent thermal management in the design.
• Moisture Sensitivity Level: Both parts are MSL 2A, requiring identical handling and storage protocols.
• Regulatory Compliance: Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

The MX3AWT-A1-0000-000BE6 (XLamp® MX-3 series) qualifies as a functional substitute despite differences in electrical characteristics (forward voltage and test current), as it meets all mechanical, optical, and regulatory requirements for direct PCB replacement.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000BE6 is the designated substitute for the obsolete MX3SWT-A1-0000-000AE6. Selection is based on the following factors:

• Product Status: The MX3AWT-A1-0000-000BE6 is active and currently manufactured, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: The substitute part carries explicit RoHS Compliance certification, providing enhanced environmental and regulatory alignment compared to the main part.
• Mechanical and Optical Compatibility: Identical package footprint, height, thermal resistance, viewing angle, and MSL rating ensure direct PCB replacement without layout modifications.
• Color and CCT Matching: Both parts deliver 3500K warm white output with 80 CRI, maintaining color consistency in lighting applications.
• Electrical Differences: The substitute operates at lower forward voltage (3.7V vs. 10.7V) and higher test current (350mA vs. 115mA). Circuit design must accommodate these electrical characteristics through appropriate current-limiting and voltage regulation.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000BE6 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000AE6?

A: Yes, from a mechanical and optical standpoint. Both parts share identical package geometry (5.00mm × 5.00mm, 1.48mm height), thermal resistance (11°C/W), viewing angle (120°), and color specification (3500K warm white, 80 CRI). However, the circuit design must be modified to accommodate the different electrical characteristics: the substitute operates at 3.7V forward voltage and 350mA test current, compared to 10.7V and 115mA for the original part.

Q: What are the key differences between these two parts?

A: The primary differences are electrical. The MX3AWT-A1-0000-000BE6 operates at significantly lower forward voltage (3.7V vs. 10.7V) and higher test current (350mA vs. 115mA). The substitute also carries explicit RoHS Compliance certification. Mechanically and optically, the parts are equivalent.

Q: Why is the MX3SWT-A1-0000-000AE6 obsolete?

A: The MX-3S series has been superseded by the newer MX-3 series within CreeLED's XLamp product line. The MX3AWT-A1-0000-000BE6 represents the current generation equivalent.

Q: Are there any packaging differences?

A: The main part is supplied in standard packaging, while the substitute (MX3AWT-A1-0000-000BE6) is available in Tape & Reel (TR) format. Both use identical 2-SMD, Gull Wing Exposed Pad configuration with 5.00mm × 5.00mm footprint.

Q: Do both parts require the same moisture handling procedures?

A: Yes. Both parts are classified as MSL 2A (4 Weeks), requiring identical moisture sensitivity handling, storage, and reflow procedures.

Q: What is the impact of the voltage and current differences on circuit design?

A: The substitute's lower forward voltage (3.7V) and higher test current (350mA) require redesign of the current-limiting circuit and power supply specifications. The original design operating at 10.7V and 115mA cannot be directly applied to the substitute without modification to voltage regulation and current limiting components.
