Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-H1-R250-000AF5 is based on the following criteria derived from the provided parameters:

Optical Compatibility: Color (White, Neutral), CCT (4250K), CRI (80), and luminous flux (91 lm at 25°C) must remain constant to maintain color consistency and light output in the application.

Mechanical Compatibility: Package type (2-SMD, Gull Wing), physical dimensions (5.00 × 5.00 mm), and maximum seated height (1.48 mm) must be identical to ensure PCB layout and assembly compatibility.

Thermal Compatibility: Thermal resistance (5°C/W) must be maintained to preserve thermal management characteristics.

Environmental Compliance: Moisture sensitivity level (2A, 4 Weeks) and REACH status (REACH Unaffected) must be consistent.

The MX6AWT-H1-R250-000AF5 meets all these criteria while offering improved electrical performance and active product status.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-R250-000AF5 is the direct substitute for the obsolete MX6SWT-H1-R250-000AF5. Both parts are manufactured by CreeLED, Inc., and maintain identical optical, mechanical, and thermal specifications.

Key Advantages of the Substitute:

The MX6AWT-H1-R250-000AF5 offers active product status with confirmed inventory availability (857 pcs), ensuring long-term supply continuity. The part achieves improved luminous efficacy (92 lm/W versus 76 lm/W), resulting in lower power consumption for equivalent light output.

Electrical Circuit Redesign Required:

Direct pin-for-pin substitution is not possible due to significant differences in forward voltage (3.3V versus 20V) and test current (300 mA versus 60 mA). Applications using the MX6SWT-H1-R250-000AF5 must be redesigned to accommodate the lower voltage and higher current characteristics of the MX6AWT-H1-R250-000AF5. Current-limiting resistors and power supply specifications must be recalculated based on the new electrical parameters.

Compliance and Environmental:

Both parts maintain identical moisture sensitivity levels (2A, 4 Weeks) and REACH compliance status, ensuring no change to handling, storage, or regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-R250-000AF5 be used as a direct replacement without circuit modification?

A: No. While optical, mechanical, and thermal parameters are identical, the electrical characteristics differ significantly. The substitute operates at 3.3V typical forward voltage and 300 mA test current, compared to 20V and 60 mA for the original part. Circuit redesign is required.

Q: Are the physical dimensions and mounting footprints identical?

A: Yes. Both parts use a 2-SMD gull wing package with 5.00 × 5.00 mm dimensions and 1.48 mm maximum seated height. PCB layout and assembly tooling remain compatible.

Q: What is the difference between "2-SMD, Gull Wing" and "2-SMD, Gull Wing Exposed Pad"?

A: The substitute includes an exposed pad for enhanced thermal management. This does not affect mechanical compatibility or PCB footprint, but may improve thermal performance in applications where the pad is thermally connected.

Q: Will the color appearance change when substituting?

A: No. Both parts are specified as White, Neutral at 4250K with CRI 80 and identical luminous flux (91 lm at 25°C). Color appearance and rendering will remain unchanged.

Q: Is the substitute part currently available?

A: Yes. The MX6AWT-H1-R250-000AF5 is classified as Active with 857 pcs in stock, ensuring availability for new designs and production.

Q: Are there any differences in handling or storage requirements?

A: No. Both parts maintain identical moisture sensitivity levels (2A, 4 Weeks) and REACH compliance status. Handling, storage, and environmental requirements are unchanged.
