Key Parameters

Substitute Part Grouping Explanation

The MX6AWT-H1-0000-000AA5 is identified as a substitute for the MX6SWT-H1-0000-000AA5 based on the following criteria:

Matching Parameters:

• Color and CCT: Both are warm white at 3750K
• Flux output: Both deliver 91 lm at test current (87–94 lm range)
• CRI: Both maintain 80 color rendering index
• Viewing angle: Both provide 120° viewing angle
• Package footprint: Both use 2-SMD gull wing configuration
• Physical dimensions: Both measure 5.00mm × 5.00mm
• Height: Both seated height maximum 1.48mm
• Thermal resistance: Both 5°C/W
• MSL rating: Both 2A (4 Weeks)
• REACH compliance: Both REACH Unaffected

Differing Parameters:

• Forward voltage: MX6AWT operates at 3.3V (vs. 20V for MX6SWT)
• Test current: MX6AWT rated at 300mA (vs. 60mA for MX6SWT)
• Maximum current: MX6AWT rated to 1A (vs. 175mA for MX6SWT)
• Efficiency: MX6AWT achieves 92 lm/W (vs. 76 lm/W for MX6SWT)
• Product status: MX6AWT is active (vs. obsolete for MX6SWT)
• Packaging: MX6AWT supplied in Tape & Reel (vs. standard packaging for MX6SWT)
• RoHS status: MX6AWT is RoHS Compliant (not specified for MX6SWT)

Substitution is valid when circuit design accommodates the lower forward voltage and higher current rating of the MX6AWT series.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-0000-000AA5 is the designated substitute for the obsolete MX6SWT-H1-0000-000AA5. Selection of the MX6AWT is supported by:

• Product availability: MX6AWT maintains active production status with 843 units in stock, whereas MX6SWT is obsolete
• Regulatory compliance: MX6AWT carries RoHS Compliant certification, ensuring alignment with current environmental standards
• Optical equivalence: Both parts deliver identical luminous flux (91 lm), color temperature (3750K), color rendering index (80), and viewing angle (120°)
• Thermal characteristics: Identical thermal resistance (5°C/W) and MSL rating (2A, 4 Weeks) ensure equivalent thermal management and handling requirements
• Physical compatibility: Identical footprint (5.00mm × 5.00mm) and height (1.48mm) permit direct PCB layout reuse

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 of the LED drive stage is mandatory. The MX6AWT's higher efficiency (92 lm/W vs. 76 lm/W) and increased maximum current rating (1A vs. 175mA) provide additional design flexibility for current-limited applications.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000AA5 be used as a direct drop-in replacement for the MX6SWT-H1-0000-000AA5?

A: No. While both parts share identical optical output, color temperature, viewing angle, and physical footprint, the MX6AWT requires a different LED drive circuit. The MX6AWT operates at 3.3V forward voltage with 300mA test current, whereas the MX6SWT requires 20V at 60mA. The drive electronics must be redesigned to accommodate the lower voltage and higher current characteristics of the MX6AWT.

Q: Are the package dimensions identical between these two parts?

A: Yes. Both the MX6SWT and MX6AWT measure 5.00mm × 5.00mm with a maximum seated height of 1.48mm. The PCB footprint and assembly height clearances are identical. The MX6AWT features an exposed pad variant of the 2-SMD gull wing package, which may provide improved thermal performance in high-power applications.

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

A: Substitution between warm white 3750K XLamp MX-series LEDs is determined by: color and CCT matching, luminous flux equivalence, CRI consistency, viewing angle alignment, package footprint compatibility, and thermal resistance equivalence. The MX6AWT meets all these criteria. However, forward voltage and test current are design-dependent parameters that require circuit-level evaluation.

Q: Is the MX6AWT RoHS compliant?

A: Yes. The MX6AWT-H1-0000-000AA5 is RoHS Compliant. The MX6SWT compliance status is not specified in the available documentation.

Q: What is the thermal resistance of these LEDs?

A: Both the MX6SWT and MX6AWT have a thermal resistance of 5°C/W, indicating equivalent thermal performance and heat dissipation characteristics.

Q: Are there any moisture sensitivity differences?

A: No. Both parts carry an MSL rating of 2A (4 Weeks), requiring identical moisture control and storage protocols during manufacturing and assembly.
