Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-H1-0000-000F50 is determined by the following critical parameters:

Color and Correlated Color Temperature (CCT): Both the main part and substitute must maintain cool white 6000K specification to ensure consistent color output in lighting applications.

Viewing Angle: The 120° viewing angle is a fixed optical characteristic that must be preserved for beam pattern compatibility.

Mounting Type and Package: Surface mount technology with 2-SMD, Gull Wing configuration ensures mechanical and electrical compatibility with existing PCB layouts.

Physical Dimensions: The 5.00mm × 5.00mm footprint and 1.48mm maximum seated height must match to prevent assembly and thermal management issues.

Thermal Resistance: The 5°C/W thermal resistance specification must be maintained for consistent thermal performance.

The MX6AWT-H1-0000-000D50 qualifies as a substitute based on these parameters. However, this substitute operates at significantly different electrical characteristics (3.3V forward voltage, 300mA test current) compared to the main part (20V, 60mA), requiring circuit redesign and is therefore suitable only for new designs rather than direct replacement in existing applications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement in Existing Designs: The MX6AWT-H1-0000-000D50 is not suitable as a direct drop-in replacement due to fundamental differences in forward voltage (20V vs. 3.3V) and test current (60mA vs. 300mA). Direct substitution would require complete redesign of the LED driver circuit and power supply topology.

For New Design Implementation: The MX6AWT-H1-0000-000D50 is an active product from the same manufacturer (CreeLED, Inc.) with identical color temperature (6000K), viewing angle (120°), and physical footprint (5.00mm × 5.00mm). This part offers improved luminous efficacy (112 lm/W vs. 105 lm/W) and active product status, making it suitable for new applications where circuit design can accommodate the lower voltage and higher current requirements.

Compliance Considerations: The MX6AWT-H1-0000-000D50 carries RoHS Compliant certification, whereas the main part does not specify RoHS status. Both parts maintain REACH Unaffected status and identical MSL ratings (2A, 4 Weeks).

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000D50 replace the MX6SWT-H1-0000-000F50 in an existing circuit?

A: No. The substitute part operates at 3.3V forward voltage compared to the main part's 20V specification. This fundamental difference requires redesign of the LED driver circuit, power supply, and current limiting components. Direct substitution without circuit modification will result in component failure.

Q: What are the key compatibility factors between these parts?

A: Both parts share identical color temperature (6000K cool white), viewing angle (120°), physical footprint (5.00mm × 5.00mm), seated height (1.48mm), and thermal resistance (5°C/W). These parameters ensure optical and mechanical compatibility in applications where electrical characteristics can be accommodated.

Q: Why is the MX6SWT-H1-0000-000F50 classified as obsolete?

A: Product status is determined by the manufacturer. The obsolete classification indicates that CreeLED, Inc. has discontinued production of this part. The active MX6AWT-H1-0000-000D50 represents the current generation equivalent within the XLamp® MX series.

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

A: The exposed pad variant (MX6AWT-H1-0000-000D50) includes an additional thermal pad on the package underside for enhanced heat dissipation. Both packages maintain identical external dimensions and footprint compatibility.

Q: Are there differences in luminous output between these parts?

A: Yes. At their respective test currents, the MX6SWT-H1-0000-000F50 produces 126 lumens while the MX6AWT-H1-0000-000D50 produces 111 lumens. However, the substitute achieves higher luminous efficacy (112 lm/W vs. 105 lm/W), indicating more efficient light generation per watt of input power.

Q: What is the moisture sensitivity level (MSL) and why does it matter?

A: Both parts carry MSL 2A rating, indicating a 4-week floor life after moisture barrier bag opening. This specification is critical for storage, handling, and assembly planning to prevent moisture-induced solder joint failures during reflow processes.
