Key Parameters

Substitute Part Grouping Explanation

The MX6AWT-A1-0000-000E50 is identified as a substitute for the MX3SWT-A1-0000-000E50 based on the following alignment criteria:

Matching Parameters:

• Color and CCT: Both White, Cool 6000K
• Flux @ 25°C: Both 118 lm (114–122 lm range)
• CRI: Both 75 (Typ)
• Viewing Angle: Both 120°
• Package / Case: Both 2-SMD, Gull Wing Exposed Pad
• Physical Dimensions: Both 5.00mm × 5.00mm
• Height (Seated Max): Both 1.48mm
• Moisture Sensitivity Level: Both 2A (4 Weeks)

Differing Parameters:

• Forward Voltage: MX3SWT 10.7V vs. MX6AWT 3.3V
• Test Current: MX3SWT 115mA vs. MX6AWT 300mA
• Maximum Current: MX3SWT 175mA vs. MX6AWT 1A
• Lumens/Watt: MX3SWT 96 lm/W vs. MX6AWT 119 lm/W
• Thermal Resistance: MX3SWT 11°C/W vs. MX6AWT 5°C/W
• Product Status: MX3SWT Obsolete vs. MX6AWT Active
• Packaging: MX3SWT Unspecified vs. MX6AWT Tape & Reel (TR)

Substitution is valid when optical output (lumens, color, CRI, viewing angle) and mechanical compatibility (package, dimensions, height) are the primary selection criteria. Circuit-level integration requires verification of voltage and current requirements.

Parameter Comparison

Engineering Selection Recommendations

For Optical Compatibility: The MX6AWT-A1-0000-000E50 provides identical luminous flux (118 lm), color temperature (6000K), color rendering index (75), and viewing angle (120°) as the MX3SWT-A1-0000-000E50. Both parts share the same 2-SMD Gull Wing Exposed Pad package and physical footprint (5.00mm × 5.00mm × 1.48mm), enabling direct mechanical substitution on PCB layouts.

For Circuit Integration: The MX6AWT operates at 3.3V forward voltage with a test current of 300mA, compared to the MX3SWT's 10.7V and 115mA. Circuit redesign is required to accommodate the lower voltage and higher current characteristics. The MX6AWT's improved thermal resistance (5°C/W vs. 11°C/W) and higher efficiency (119 lm/W vs. 96 lm/W) provide thermal and power management advantages.

For Production Continuity: The MX6AWT-A1-0000-000E50 is classified as Active with RoHS Compliant status and standard Tape & Reel packaging, ensuring long-term availability and supply chain stability compared to the obsolete MX3SWT. Both parts maintain identical REACH and ECCN compliance classifications.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000E50 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000E50?

A: Mechanical compatibility is confirmed—both parts share identical package type (2-SMD Gull Wing Exposed Pad), footprint (5.00mm × 5.00mm), and height (1.48mm). Electrical compatibility requires circuit redesign due to differing forward voltage (3.3V vs. 10.7V) and test current (300mA vs. 115mA) specifications.

Q: Are the optical outputs equivalent?

A: Yes. Both parts deliver 118 lumens at 25°C within the same range (114–122 lm), maintain 6000K color temperature, and provide 75 CRI with 120° viewing angle. Optical performance is functionally equivalent.

Q: What are the thermal management differences?

A: The MX6AWT-A1-0000-000E50 has superior thermal performance with 5°C/W thermal resistance compared to the MX3SWT's 11°C/W. This results in lower junction temperatures under equivalent power dissipation and improved long-term reliability.

Q: Is the MX6AWT available in the same packaging format?

A: The MX6AWT is supplied in Tape & Reel (TR) format, while the MX3SWT packaging specification is not detailed in available data. Both parts are classified as 2-SMD, Gull Wing Exposed Pad with identical physical dimensions, suitable for automated assembly processes.

Q: What compliance certifications apply to both parts?

A: Both the MX3SWT-A1-0000-000E50 and MX6AWT-A1-0000-000E50 are REACH Unaffected and classified under ECCN EAR99 with HTSUS code 8541.41.0000. The MX6AWT additionally carries RoHS Compliant certification. Both maintain MSL 2A (4 Weeks) moisture sensitivity classification.
