MX3SWT-A1-0000-0008F8 Equivalent & Substitute Parts

Part Overview

The MX3SWT-A1-0000-0008F8 is a CreeLED XLamp® MX-3S warm white LED (2850K) designed for surface mount applications. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production and maintenance requirements. The MX-3S series has been superseded by newer generations within the XLamp product line, necessitating substitute part evaluation for design continuity and supply chain management.

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-0008F8 is evaluated based on the following critical parameters:

Mandatory Matching Criteria:

• Color and CCT: White, Warm 2850K
• CRI: 80 (Typ)
• Viewing Angle: 120°
• Package / Case: 2-SMD, Gull Wing Exposed Pad
• Physical Dimensions: 5.00mm × 5.00mm footprint
• Height: 1.48mm maximum
• Thermal Resistance: 11°C/W
• MSL Rating: 2A (4 Weeks)

Allowable Variation Parameters:

• Forward Voltage (Vf): Acceptable within circuit design constraints
• Test Current and Maximum Current: Acceptable if circuit topology accommodates
• Lumens/Watt efficiency: Acceptable if flux output meets application requirements
• Product Status: Active status preferred for long-term supply assurance

The substitute part MX3AWT-A1-0000-0008F8 maintains identical physical packaging, thermal characteristics, color specification, and MSL rating. Electrical parameters differ due to the MX-3 series architecture, requiring circuit-level verification.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-0008F8 serves as the active production equivalent to the obsolete MX3SWT-A1-0000-0008F8. Both components share identical photometric output (77lm at 2850K), color rendering (CRI 80), viewing angle (120°), and physical packaging specifications.

The primary distinction lies in electrical architecture: the MX3AWT operates at 3.7V nominal with 350mA test current, compared to the MX3SWT's 10.7V at 115mA. This voltage and current differential reflects the evolution from the MX-3S to MX-3 series topology and requires circuit redesign at the power supply and current limiting stages.

The MX3AWT-A1-0000-0008F8 carries Active product status and RoHS Compliance certification, providing supply continuity and regulatory alignment advantages over the obsolete MX3SWT variant. Both components maintain identical thermal resistance (11°C/W) and moisture sensitivity ratings (2A, 4 Weeks), ensuring equivalent thermal management and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-0008F8 be used as a direct drop-in replacement for the MX3SWT-A1-0000-0008F8?

A: Physical and thermal compatibility is confirmed. The 5.00mm × 5.00mm footprint, 1.48mm height, gull wing exposed pad configuration, and 11°C/W thermal resistance are identical. However, the forward voltage difference (3.7V vs. 10.7V) and test current difference (350mA vs. 115mA) require circuit-level modifications to the power supply and current limiting network. PCB layout and thermal management remain compatible.

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

A: Substitution is determined by matching: color and CCT (2850K warm white), CRI (80 Typ), viewing angle (120°), package type (2-SMD gull wing exposed pad), physical dimensions (5.00mm × 5.00mm), height (1.48mm), thermal resistance (11°C/W), and MSL rating (2A, 4 Weeks). Electrical parameters (Vf, test current, maximum current) may vary if the application circuit is redesigned accordingly.

Q: Why does the MX3AWT have different voltage and current specifications?

A: The MX3AWT-A1-0000-0008F8 belongs to the MX-3 series, which represents a subsequent generation of XLamp technology from the MX-3S series. The architectural differences result in the lower forward voltage (3.7V) and higher test current (350mA) profile while maintaining identical luminous flux output and color characteristics.

Q: Is the MX3AWT-A1-0000-0008F8 available in the same packaging format?

A: Yes. Both components use 2-SMD gull wing exposed pad packaging with identical 5.00mm × 5.00mm footprint and 1.48mm maximum height. The MX3AWT is supplied in Tape & Reel (TR) format, which is standard for production volume applications.

Q: What compliance certifications apply to the substitute part?

A: The MX3AWT-A1-0000-0008F8 carries RoHS Compliance certification and maintains REACH Unaffected status. Both components are classified under ECCN EAR99 and HTSUS 8541.41.0000. The MSL rating of 2A (4 Weeks) applies to both variants.

Q: Are there any thermal management differences between the two parts?

A: No. Both components specify identical thermal resistance of 11°C/W, ensuring equivalent thermal performance in the same circuit environment. Thermal management design does not require modification for substitution.
