Key Parameters

Substitute Part Grouping Explanation

The MX6AWT-H1-0000-000D50 is identified as a substitute for the MX6SWT-H1-0000-000E50 based on the following allowable parameters:

Matching Parameters:

• Color and CCT: Both are White, Cool 6000K
• Viewing Angle: Both provide 120° viewing angle
• CRI: Both maintain 80 Color Rendering Index
• Mounting Type: Both are Surface Mount
• Package Footprint: Both use 2-SMD, Gull Wing configuration with identical 5.00mm x 5.00mm dimensions
• Height: Both have 1.48mm maximum seated height
• Thermal Resistance: Both rated at 5°C/W
• MSL Rating: Both classified as 2A (4 Weeks)
• REACH Status: Both REACH Unaffected

Differing Parameters (Allowable for Substitution):

• Series: MX-6S (obsolete) vs. MX-6 (active)
• Voltage - Forward (Vf): 20V vs. 3.3V
• Current - Test: 60mA vs. 300mA
• Flux @ 25°C: 118lm vs. 111lm
• Lumens/Watt: 98 lm/W vs. 112 lm/W
• Current - Max: 175mA vs. 1A
• Package Detail: Standard Gull Wing vs. Gull Wing Exposed Pad
• Product Status: Obsolete vs. Active
• Packaging: Loose vs. Tape & Reel (TR)

The substitute operates at significantly lower voltage (3.3V vs. 20V) and higher current (300mA vs. 60mA), resulting in improved efficiency (112 lm/W vs. 98 lm/W) while maintaining comparable luminous output and identical optical/mechanical form factor.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-0000-000D50 is the designated substitute for the obsolete MX6SWT-H1-0000-000E50. Selection of the substitute is justified by:

• Product Status: The original part is obsolete; the substitute is active and in production with 1025 units currently in stock.
• Regulatory Compliance: Both parts maintain REACH Unaffected status, ensuring equivalent regulatory standing.
• Form Factor Compatibility: Identical footprint (5.00mm x 5.00mm), height (1.48mm), and mounting type enable direct PCB layout compatibility.
• Optical Performance: Both deliver 120° viewing angle and 80 CRI, maintaining identical light distribution and color rendering characteristics.
• Thermal Management: Equivalent 5°C/W thermal resistance ensures comparable thermal performance in existing thermal designs.

The primary design consideration is the voltage and current operating point shift (20V/60mA to 3.3V/300mA). Circuit redesign is required to accommodate the lower forward voltage and higher current draw. The substitute delivers superior efficiency (112 lm/W vs. 98 lm/W) with comparable luminous output (111lm vs. 118lm).

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000D50 be used as a direct drop-in replacement without circuit modification?

A: No. The substitute operates at 3.3V forward voltage compared to the original 20V. The current-limiting circuit must be redesigned to accommodate the lower voltage and higher current (300mA test current vs. 60mA). PCB layout remains compatible due to identical package dimensions.

Q: What is the difference between the 2-SMD Gull Wing and 2-SMD Gull Wing Exposed Pad packages?

A: The substitute includes an exposed thermal pad for enhanced heat dissipation. Both packages maintain identical external dimensions (5.00mm x 5.00mm, 1.48mm height) and are compatible with standard SMD assembly processes. The exposed pad provides improved thermal performance in high-power applications.

Q: Are there any compliance or regulatory differences between the two parts?

A: No. Both parts maintain REACH Unaffected status and identical MSL ratings (2A, 4 Weeks). Regulatory standing is equivalent.

Q: Why does the substitute have higher lumens per watt efficiency?

A: The MX6AWT-H1-0000-000D50 represents a newer generation of the XLamp® MX series with improved LED die efficiency. At the substitute's test current (300mA), the device delivers 112 lm/W compared to 98 lm/W for the original part at 60mA. This reflects advances in LED manufacturing technology between the MX-6S and MX-6 series.

Q: Is the luminous flux output comparable between the two parts?

A: Yes, within acceptable engineering tolerance. The original delivers 118lm at 60mA/25°C; the substitute delivers 111lm at 300mA/25°C. The 6% difference in absolute flux is offset by the superior efficiency and active product status of the substitute.

Q: What packaging format is available for the substitute?

A: The MX6AWT-H1-0000-000D50 is supplied in Tape & Reel (TR) format, suitable for automated assembly. The original part is available as loose components.
