Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-H1-R250-000CB4 is determined by the following critical parameters:

Mechanical Compatibility: Identical package type (2-SMD, Gull Wing), footprint dimensions (5.00mm x 5.00mm), and maximum seated height (1.48mm) ensure PCB layout compatibility.

Optical Compatibility: White color and 120° viewing angle must be maintained for application requirements.

Thermal Compatibility: Thermal resistance of 5°C/W must be preserved to ensure equivalent thermal performance in the application circuit.

Electrical Compatibility: Forward voltage, test current, maximum current, and luminous flux parameters determine functional equivalence. The substitute part MX6AWT-H1-R250-000CB3 shares identical mechanical and optical specifications but operates at different electrical parameters (3.3V, 300mA test current).

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-R250-000CB3 is available as an Active product from CreeLED, Inc., providing supply continuity for the Obsolete MX6SWT-H1-R250-000CB4. Both components share identical mechanical footprints, optical characteristics (white color, 120° viewing angle), and thermal properties (5°C/W).

The primary distinction is electrical operation: the MX6AWT operates at 3.3V with 300mA test current, compared to the MX6SWT's 20V and 60mA specifications. The MX6AWT also features an exposed pad variant of the 2-SMD, Gull Wing package and achieves higher luminous efficiency (105 lm/W versus 87 lm/W).

Both components maintain identical luminous flux output (104lm at 25°C) and comply with REACH and EAR99 classifications. The MX6AWT-H1-R250-000CB3 is RoHS Compliant, providing additional regulatory alignment for modern applications.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-R250-000CB3 directly replace the MX6SWT-H1-R250-000CB4 on the same PCB?

A: Mechanical and optical compatibility is confirmed. Both components use identical 5.00mm x 5.00mm footprints, 1.48mm maximum seated height, and 2-SMD Gull Wing packaging. However, the electrical operating parameters differ significantly (20V/60mA versus 3.3V/300mA), requiring circuit redesign to accommodate the substitute part's voltage and current requirements.

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

A: Substitution is determined by: package type and footprint dimensions (2-SMD, Gull Wing, 5.00mm x 5.00mm), color (White), viewing angle (120°), thermal resistance (5°C/W), and luminous flux output (104lm at 25°C). Electrical parameters (forward voltage and test current) must be evaluated against specific application circuit requirements.

Q: Does the exposed pad on the MX6AWT-H1-R250-000CB3 affect PCB layout compatibility?

A: The exposed pad variant does not affect footprint compatibility. The 5.00mm x 5.00mm dimensions and 1.48mm maximum height remain identical. PCB designs must accommodate the exposed pad thermal connection if thermal management is a design consideration.

Q: Are both parts compliant with current regulatory standards?

A: Both components are REACH Unaffected and classified as EAR99. The MX6AWT-H1-R250-000CB3 additionally carries RoHS Compliance certification, meeting modern regulatory requirements for electronic components.

Q: What is the impact of the different luminous efficiency ratings?

A: The MX6AWT-H1-R250-000CB3 delivers 105 lm/W compared to the MX6SWT-H1-R250-000CB4's 87 lm/W. Both produce identical luminous flux (104lm) at their respective test currents, indicating improved power efficiency in the substitute part.
