Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-H1-0000-000BB7 is based on the following critical parameters that must align for functional equivalence:

Mechanical Compatibility: Identical package type (2-SMD, Gull Wing), identical physical dimensions (5.00mm x 5.00mm), and identical maximum seated height (1.48mm) ensure PCB footprint compatibility without redesign.

Optical Performance: Matching viewing angle (120°) and color (White) maintain consistent light distribution and color characteristics in the application.

Thermal Properties: Identical thermal resistance (5°C/W) ensures equivalent thermal management performance.

Environmental Compliance: REACH Unaffected status and MSL rating (2A, 4 Weeks) maintain regulatory and handling requirements.

The MX6AWT-H1-0000-000BB7 qualifies as a substitute based on these mechanical and optical parameters. However, this substitute operates at significantly different electrical parameters (3.3V forward voltage, 300mA test current) and therefore requires circuit redesign and validation for electrical compatibility.

Engineering Selection Recommendations

The MX6AWT-H1-0000-000BB7 is the identified substitute for the obsolete MX6SWT-H1-0000-000BB7. Selection of this substitute is supported by the following factors:

Product Status: The MX6AWT-H1-0000-000BB7 maintains Active product status, ensuring ongoing availability and manufacturer support, whereas the main part is Obsolete.

Regulatory Compliance: Both parts maintain REACH Unaffected status and identical MSL ratings, ensuring equivalent environmental and handling compliance.

Mechanical Compatibility: Identical package footprint, dimensions, and thermal resistance enable direct PCB placement without layout modification.

Optical Equivalence: Matching viewing angle and white color output maintain consistent optical performance in the application.

Electrical Redesign Required: The substitute operates at 3.3V forward voltage and 300mA test current, compared to the main part's 20V and 60mA. Circuit redesign, including power supply modification and current limiting adjustments, is necessary for electrical compatibility.

Performance Improvement: The substitute delivers superior luminous efficiency (98 lm/W versus 81 lm/W), providing enhanced energy efficiency in the application.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000BB7 be used as a direct drop-in replacement for the MX6SWT-H1-0000-000BB7?

A: No. While both parts share identical mechanical and optical specifications (package, dimensions, viewing angle, color), they operate at fundamentally different electrical parameters. The MX6AWT requires 3.3V forward voltage and 300mA test current, whereas the MX6SWT requires 20V and 60mA. Circuit redesign is mandatory.

Q: What are the key mechanical compatibility factors?

A: Both parts use identical 2-SMD Gull Wing packages with 5.00mm x 5.00mm footprints and 1.48mm maximum seated height. The MX6AWT includes an exposed pad variant, which provides improved thermal performance but does not affect footprint compatibility. Both maintain 5°C/W thermal resistance.

Q: Are there any compliance or handling differences?

A: No. Both parts maintain REACH Unaffected status and identical MSL ratings (2A, 4 Weeks), ensuring equivalent regulatory compliance and moisture handling requirements.

Q: Why does the MX6AWT have higher lumens per watt efficiency?

A: The MX6AWT operates at lower forward voltage (3.3V versus 20V) and higher test current (300mA versus 60mA), resulting in improved luminous efficiency (98 lm/W versus 81 lm/W) at its specified operating point.

Q: What circuit modifications are required for substitution?

A: Power supply voltage must be adjusted from 20V to 3.3V. Current limiting resistors or driver circuits must be recalculated for 300mA operation. Forward voltage drop changes from 20V to 3.3V, affecting power dissipation calculations and thermal management design.

Q: Is the exposed pad on the MX6AWT package significant?

A: The exposed pad improves thermal dissipation by providing direct thermal contact to the PCB. This is beneficial for thermal management but does not affect electrical or optical compatibility. Standard PCB design practices for exposed pad packages should be followed.
