MX6SWT-H1-0000-0009F6 Equivalent & Substitute Parts

Part Overview

The MX6SWT-H1-0000-0009F6 is an XLamp® MX-6S warm white LED (3700K) designed for surface mount applications requiring 20V forward voltage and 60mA test current. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The MX-6S series has been superseded by the MX-6 series, which maintains compatible form factors and optical characteristics while offering improved electrical efficiency and active product status.

Key Parameters

Substitute Part Grouping Explanation

The MX6AWT-H1-0000-0009F6 qualifies as a substitute based on the following matching parameters:

• Color and CCT: Both parts are White, Warm 3700K
• Luminous flux: Both deliver 84lm (81lm ~ 87lm) at test conditions
• Viewing angle: Both maintain 120° viewing angle
• Physical dimensions: Both are 5.00mm x 5.00mm with 1.48mm maximum seated height
• Thermal resistance: Both have 5°C/W package thermal resistance
• Mounting type: Both are surface mount 2-SMD, Gull Wing configurations
• MSL rating: Both are 2A (4 Weeks)

The primary electrical difference is the forward voltage (Vf) and test current: MX6SWT operates at 20V/60mA, while MX6AWT operates at 3.3V/300mA. This represents a fundamental circuit design change and requires verification of power supply compatibility and thermal management in the target application.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-0000-0009F6 is the active product replacement for the obsolete MX6SWT-H1-0000-0009F6. Selection between these parts depends on circuit architecture compatibility:

• The MX6AWT offers RoHS compliance and active product status, supporting long-term supply chain continuity.
• The MX6AWT demonstrates superior luminous efficiency (85 lm/W vs. 70 lm/W), reducing thermal load in equivalent brightness applications.
• Circuit redesign is required when substituting, as the 20V/60mA electrical specification of the MX6SWT differs fundamentally from the 3.3V/300mA specification of the MX6AWT.
• Both parts maintain identical optical output (84lm), viewing angle (120°), color temperature (3700K), and physical dimensions, enabling mechanical and optical compatibility.
• Thermal management design must account for the different power dissipation profiles resulting from the voltage and current differences.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-0009F6 be used as a direct drop-in replacement for the MX6SWT-H1-0000-0009F6?

A: No. While both parts share identical physical dimensions, viewing angle, color temperature, and luminous output, they require different electrical supply voltages (20V vs. 3.3V) and operate at different currents (60mA vs. 300mA). Circuit redesign is necessary.

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

A: Substitution is based on matching color (White, Warm), CCT (3700K), luminous flux (84lm), viewing angle (120°), physical dimensions (5.00mm x 5.00mm), package type (2-SMD, Gull Wing), and MSL rating (2A). Electrical parameters (Vf and test current) differ and require application-specific evaluation.

Q: Why is the MX6AWT more efficient than the MX6SWT?

A: The MX6AWT achieves 85 lm/W compared to the MX6SWT's 70 lm/W at their respective test currents. This reflects improvements in the MX-6 series design relative to the obsolete MX-6S series.

Q: Are there packaging differences between these parts?

A: Both use 2-SMD, Gull Wing surface mount packages with identical dimensions. The MX6AWT includes an exposed pad, which may provide improved thermal performance in applications requiring enhanced heat dissipation.

Q: What is the compliance status of each part?

A: The MX6AWT-H1-0000-0009F6 is RoHS Compliant and has active product status. The MX6SWT-H1-0000-0009F6 is obsolete. Both are REACH Unaffected.
