Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MX6SWT-H1-0000-0008B8 is determined by the following critical parameters:

Mechanical Compatibility: Package type (2-SMD, Gull Wing), physical dimensions (5.00mm x 5.00mm), and maximum seated height (1.48mm) must match to ensure PCB footprint compatibility and assembly process alignment.

Optical Characteristics: Color (white) and viewing angle (120°) define the optical performance envelope for the application.

Thermal Properties: Thermal resistance of package (5°C/W) establishes thermal management requirements.

Environmental Compliance: REACH status and moisture sensitivity level (MSL 2A) must be maintained for regulatory and storage requirements.

The MX6AWT-H1-0000-0008B8 qualifies as a substitute based on matching mechanical package specifications, identical physical dimensions, equivalent thermal resistance, and compatible environmental classifications. However, this substitute operates under fundamentally different electrical parameters (3.3V forward voltage, 300mA test current) and is therefore suitable only for applications where the circuit design accommodates these electrical differences.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-0000-0008B8 is the identified substitute for the obsolete MX6SWT-H1-0000-0008B8. Selection of this substitute requires circuit-level design modifications due to significant electrical parameter differences.

Product Status Consideration: The MX6AWT-H1-0000-0008B8 maintains active product status with CreeLED, Inc., ensuring ongoing availability and supply chain continuity compared to the obsolete MX6SWT-H1-0000-0008B8.

Compliance Alignment: Both components maintain REACH Unaffected status and identical MSL 2A (4 Weeks) classifications, satisfying regulatory and storage requirement parity.

Mechanical and Thermal Compatibility: Identical package configuration (2-SMD, Gull Wing), physical dimensions (5.00mm x 5.00mm), and thermal resistance (5°C/W) enable direct PCB footprint compatibility and thermal management equivalence. The exposed pad variant in the substitute provides enhanced thermal dissipation capability.

Electrical Parameter Divergence: The substitute operates at 3.3V forward voltage with 300mA test current, compared to the main part's 20V and 60mA specifications. Circuit redesign is required to accommodate these electrical differences. The substitute delivers equivalent luminous flux (77lm) with improved efficiency (78 lm/W versus 64 lm/W).

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-0008B8 be used as a direct drop-in replacement for the MX6SWT-H1-0000-0008B8?

A: Mechanical and thermal compatibility is confirmed through matching package type, physical dimensions, and thermal resistance. However, electrical parameters differ significantly (20V/60mA versus 3.3V/300mA), requiring circuit redesign. Direct PCB footprint compatibility exists, but power supply and current limiting circuits must be modified.

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

A: The primary differences are forward voltage (20V versus 3.3V), test current (60mA versus 300mA), and maximum current rating (175mA versus 1A). Both deliver identical luminous flux at their respective test currents, with the substitute offering superior efficiency. The substitute includes an exposed pad for enhanced thermal management.

Q: Are there any compliance or environmental concerns with substitution?

A: Both components maintain identical REACH Unaffected status and MSL 2A (4 Weeks) classifications. No compliance barriers exist for substitution from an environmental or regulatory perspective.

Q: How does the exposed pad in the substitute package affect thermal performance?

A: The exposed pad in the MX6AWT-H1-0000-0008B8 provides additional thermal dissipation pathways to the PCB. Both components maintain identical thermal resistance specifications (5°C/W), but the exposed pad design in the substitute enables more effective heat transfer in practical applications.

Q: What is the impact of the CRI difference on substitution?

A: The main part specifies CRI 80, while the substitute does not provide a CRI specification. If color rendering index is a critical application requirement, this parameter difference must be evaluated against specific application needs.
