Key Parameters

Substitute Part Grouping Explanation

The MX6AWT-H1-0000-000BZ7 qualifies as a functional substitute based on the following alignment of critical parameters:

Matching Parameters:

• Color temperature: 3000K (Warm White)
• Color Rendering Index: 80
• Viewing angle: 120°
• Package configuration: 2-SMD, Gull Wing (with exposed pad on substitute)
• Physical footprint: 5.00mm × 5.00mm
• Seated height: 1.48mm
• Thermal resistance: 5°C/W
• Mounting type: Surface Mount
• Moisture sensitivity: 2A (4 Weeks)

Differing Parameters:

• Forward voltage (Vf): MX6SWT operates at 20V; MX6AWT operates at 3.3V
• Test current: MX6SWT at 60mA; MX6AWT at 300mA
• Maximum current: MX6SWT rated 175mA; MX6AWT rated 1A
• Luminous flux: MX6SWT 91lm; MX6AWT 97lm
• Efficiency: MX6SWT 76 lm/W; MX6AWT 98 lm/W
• Product status: MX6SWT is Obsolete; MX6AWT is Active
• Packaging format: MX6SWT standard; MX6AWT supplied in Tape & Reel

Substitution is valid only in applications where the circuit design can accommodate the lower forward voltage and higher current requirements of the MX6AWT series.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-0000-000BZ7 is the designated successor to the obsolete MX6SWT-H1-0000-000AZ7. Selection of the MX6AWT is supported by the following factors:

• Product Status: The MX6AWT maintains Active status, ensuring continued availability and manufacturing support, whereas the MX6SWT is Obsolete.
• Regulatory Compliance: The MX6AWT is RoHS Compliant, meeting current environmental standards. Both parts maintain REACH Unaffected and EAR99 export classification status.
• Performance Improvement: The MX6AWT delivers 6.6% higher luminous flux (97lm vs. 91lm) and 28.9% higher efficiency (98 lm/W vs. 76 lm/W) at its rated operating point.
• Mechanical Compatibility: Identical footprint (5.00mm × 5.00mm), height (1.48mm), and thermal resistance (5°C/W) enable direct PCB layout reuse.
• Optical Consistency: Matching color temperature (3000K), CRI (80), and viewing angle (120°) preserve lighting characteristics.

Critical Design Consideration: The MX6AWT operates at 3.3V forward voltage with 300mA test current, compared to the MX6SWT's 20V and 60mA. Circuit redesign is mandatory to accommodate this significant voltage and current shift. The MX6AWT's 1A maximum current rating provides greater headroom than the MX6SWT's 175mA maximum.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000BZ7 be used as a direct drop-in replacement for the MX6SWT-H1-0000-000AZ7?

A: No. While the physical footprint and optical characteristics are identical, the forward voltage differs substantially (3.3V vs. 20V). The power supply and current-limiting circuitry must be redesigned. Direct substitution without circuit modification will result in component failure.

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

A: Substitution is valid when the following parameters match: color temperature (3000K), CRI (80), viewing angle (120°), package footprint (5.00mm × 5.00mm), seated height (1.48mm), and thermal resistance (5°C/W). The MX6AWT meets all these criteria. Electrical parameters (voltage and current) must be evaluated separately within the specific circuit design.

Q: Why does the MX6AWT have an exposed pad while the MX6SWT does not?

A: The exposed pad on the MX6AWT improves thermal dissipation and electrical performance. This design enhancement is part of the MX-6 series evolution. The exposed pad does not affect mechanical compatibility on standard PCB layouts designed for gull wing packages.

Q: Is the MX6AWT available in the same packaging format as the MX6SWT?

A: The MX6AWT is supplied in Tape & Reel (TR) format, whereas the MX6SWT was supplied in standard packaging. Both formats are compatible with automated assembly equipment. Tape & Reel packaging is the current industry standard for high-volume production.

Q: What compliance certifications apply to the MX6AWT?

A: The MX6AWT is RoHS Compliant and maintains REACH Unaffected status. Both parts share EAR99 export classification. These certifications support use in regulated markets and applications with environmental compliance requirements.

Q: How does the efficiency improvement of the MX6AWT affect thermal management?

A: The MX6AWT's 28.9% efficiency gain (98 lm/W vs. 76 lm/W) reduces heat generation per unit of light output. Both parts maintain identical thermal resistance (5°C/W), so thermal management strategies remain consistent. The improved efficiency may reduce cooling requirements in thermally constrained designs.
