Substitute Part Grouping Explanation

The MX6AWT-A1-0000-000DF4 qualifies as a functional substitute for the MX3SWT-A1-0000-000DF4 based on the following criteria:

Matching Parameters:

• Color and CCT: Both parts are white neutral 4750K LEDs
• Flux output: Both deliver 111 lm at their respective test currents (107–114 lm range)
• CRI: Both maintain 75 (Typ) color rendering index
• Viewing angle: Both provide 120° beam angle
• Package / Case: Both use 2-SMD, Gull Wing Exposed Pad configuration
• Physical dimensions: Both measure 0.197" L × 0.197" W (5.00 mm × 5.00 mm)
• Height: Both have 0.058" (1.48 mm) maximum seated height
• Moisture sensitivity: Both rated MSL 2A (4 Weeks)
• REACH compliance: Both REACH Unaffected

Differing Parameters:

• Forward voltage: MX6AWT operates at 3.3V (vs. 10.7V for MX3SWT)
• Test current: MX6AWT rated at 300 mA (vs. 115 mA for MX3SWT)
• Maximum current: MX6AWT rated at 1A (vs. 175 mA for MX3SWT)
• Lumens/Watt efficiency: MX6AWT achieves 112 lm/W (vs. 90 lm/W for MX3SWT)
• Thermal resistance: MX6AWT has 5°C/W (vs. 11°C/W for MX3SWT)
• Product status: MX6AWT is Active (vs. Obsolete for MX3SWT)
• Packaging: MX6AWT supplied in Tape & Reel (vs. standard packaging for MX3SWT)

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-A1-0000-000DF4 is the designated substitute for the obsolete MX3SWT-A1-0000-000DF4. Both parts maintain identical optical output (111 lm at 4750K, 75 CRI, 120° viewing angle) and physical form factor (5.00 mm × 5.00 mm, 1.48 mm height), ensuring mechanical and optical compatibility in existing PCB layouts.

The primary design consideration is electrical: the MX6AWT operates at 3.3V with 300 mA test current, compared to the MX3SWT's 10.7V and 115 mA. Circuit designs must be re-evaluated to accommodate the lower forward voltage and higher current requirements. The MX6AWT's improved thermal resistance (5°C/W vs. 11°C/W) and higher efficiency (112 lm/W vs. 90 lm/W) provide thermal and power consumption benefits.

Both parts carry identical compliance certifications: REACH Unaffected, MSL 2A (4 Weeks), and ECCN EAR99. The MX6AWT's active product status ensures long-term availability and supply chain continuity, whereas the MX3SWT is obsolete.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000DF4 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000DF4?

A: The MX6AWT is mechanically and optically compatible (same package, dimensions, and light output), but electrical redesign is required. The forward voltage differs significantly (3.3V vs. 10.7V), necessitating circuit modifications to the LED driver or power supply stage.

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

A: The primary differences are forward voltage (3.3V vs. 10.7V), test current (300 mA vs. 115 mA), maximum current rating (1A vs. 175 mA), thermal resistance (5°C/W vs. 11°C/W), and product status (Active vs. Obsolete). Optical and physical characteristics are identical.

Q: Are both parts available in the same packaging format?

A: Both parts use the same 2-SMD, Gull Wing Exposed Pad package with identical dimensions (5.00 mm × 5.00 mm, 1.48 mm height). The MX6AWT is supplied in Tape & Reel format, while the MX3SWT uses standard packaging.

Q: Do these parts have the same color temperature and CRI?

A: Yes. Both are white neutral 4750K LEDs with 75 (Typ) CRI, ensuring identical color output and rendering characteristics.

Q: What compliance certifications apply to both parts?

A: Both parts are REACH Unaffected, carry MSL 2A (4 Weeks) moisture sensitivity rating, and are classified as ECCN EAR99.
