MX6SWT-H1-R250-000EF5 Equivalent & Substitute Parts

Part Overview

The MX6SWT-H1-R250-000EF5 is an XLamp® MX-6S neutral white LED (4250K) designed for surface mount applications requiring high luminous efficacy and compact form factor. This part operates at 20V forward voltage with 60mA test current, delivering 118lm at 25°C with 98 lm/W efficiency and 80 CRI. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

The MX6AWT-H1-R250-000CF5 is identified as a substitute based on the following matching criteria:

Matching Parameters:

• Color and CCT: Both parts deliver neutral white light at 4250K
• Viewing Angle: Both maintain 120° beam angle
• Package Footprint: Both use 2-SMD, Gull Wing configuration with identical 5.00mm × 5.00mm dimensions
• Height: Both seated height maximum is 1.48mm
• Thermal Resistance: Both rated at 5°C/W
• Moisture Sensitivity: Both classified as MSL 2A (4 Weeks)
• Compliance: Both REACH Unaffected and ECCN EAR99

Differing Parameters: The substitute operates at significantly different electrical parameters (3.3V forward voltage, 300mA test current) compared to the main part (20V, 60mA). This electrical difference requires circuit-level evaluation for compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-R250-000CF5 is an active product with RoHS compliance, providing supply continuity for the obsolete MX6SWT-H1-R250-000EF5. Both parts share identical physical dimensions, thermal characteristics, and optical properties (color, CRI, viewing angle).

Substitution feasibility depends on circuit architecture compatibility. The MX6AWT operates at 3.3V with 300mA test current versus the MX6SWT's 20V and 60mA specification. Designs using series-connected LED strings or high-voltage driver topologies may require significant modification. Designs using current-regulated drivers or parallel configurations may accommodate the substitute with driver reconfiguration.

The MX6AWT delivers 105 lm/W efficiency compared to 98 lm/W for the MX6SWT, with slightly lower absolute flux (104lm versus 118lm at test current). The exposed pad variant of the MX6AWT provides enhanced thermal management capability.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-R250-000CF5 be used as a direct drop-in replacement for the MX6SWT-H1-R250-000EF5?

A: Physical and thermal compatibility is confirmed. Electrical compatibility requires circuit evaluation. The 20V to 3.3V voltage difference and 60mA to 300mA current difference necessitate driver circuit redesign. Direct PCB substitution without driver modification will result in component failure.

Q: What are the key matching parameters between these parts?

A: Color temperature (4250K neutral white), CRI (80), viewing angle (120°), package footprint (5.00mm × 5.00mm), seated height (1.48mm), thermal resistance (5°C/W), and moisture sensitivity rating (2A, 4 Weeks) are identical across both parts.

Q: How do the optical outputs compare?

A: At their respective test currents, the MX6SWT delivers 118lm while the MX6AWT delivers 104lm. The MX6AWT achieves higher efficiency at 105 lm/W versus 98 lm/W. Absolute flux difference is approximately 12% lower for the substitute at its rated test current.

Q: What is the significance of the exposed pad on the MX6AWT?

A: The exposed pad variant improves thermal coupling to the PCB, enhancing heat dissipation. This is beneficial for high-current applications but requires appropriate PCB thermal design to realize the advantage.

Q: Are there compliance or supply chain advantages to using the MX6AWT?

A: The MX6AWT is an active product with confirmed RoHS compliance and current manufacturing status, ensuring long-term availability. The MX6SWT is obsolete with no ongoing production.
