MX6SWT-H1-0000-000AF6 Equivalent & Substitute Parts

Part Overview

The MX6SWT-H1-0000-000AF6 is an XLamp® MX-6S warm white LED (3700K) designed for surface mount applications requiring 20V forward voltage and 60mA test current. This part 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 The MX-6S series has been superseded by the MX-6 series, which offers improved performance characteristics while maintaining compatible physical dimensions and thermal properties.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-H1-0000-000AF6 is based on the following critical parameters:

Electrical Compatibility Criteria:

• Color and CCT (3700K warm white) must match
• CRI (80) must match
• Viewing angle (120°) must match
• Physical dimensions (5.00mm x 5.00mm footprint, 1.48mm max height) must match
• Thermal resistance (5°C/W) must match
• Mounting type (Surface Mount, 2-SMD Gull Wing) must match

Functional Equivalence: The MX6AWT-H1-0000-000AF6 qualifies as a substitute because it maintains identical color temperature, CRI, viewing angle, physical footprint, height, and thermal characteristics. While the substitute operates at different voltage (3.3V vs. 20V) and current (300mA vs. 60mA test current) specifications, it is the designated successor in the XLamp® product line and provides equivalent luminous flux output at its rated test current.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: MX6AWT-H1-0000-000AF6

The MX6AWT-H1-0000-000AF6 is the active production equivalent for the obsolete MX6SWT-H1-0000-000AF6. Selection of this substitute is based on:

• Active product status ensures ongoing availability and supply chain continuity
• RoHS compliance certification provides regulatory advantage over the main part
• Identical optical and thermal characteristics (color, CRI, viewing angle, thermal resistance, physical dimensions)
• Equivalent luminous flux output (91lm at rated test current)
• Same moisture sensitivity level and REACH status

Critical Design Consideration:

Circuit design must accommodate the different electrical operating point. The substitute operates at 3.3V forward voltage with 300mA test current, compared to the main part's 20V and 60mA. Current-limiting resistor values and power supply voltage requirements must be recalculated for the substitute part to ensure proper operation and thermal management.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000AF6 be used as a direct drop-in replacement for the MX6SWT-H1-0000-000AF6?

A: Physical and optical compatibility is confirmed (identical footprint, height, color, CRI, and viewing angle). However, electrical circuit redesign is required due to different forward voltage (3.3V vs. 20V) and test current (300mA vs. 60mA) specifications. The PCB layout may remain unchanged, but current-limiting resistors and power supply connections must be modified.

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

A: Substitution is determined by matching: color temperature (3700K), CRI (80), viewing angle (120°), physical dimensions (5.00mm x 5.00mm footprint, 1.48mm max height), thermal resistance (5°C/W), and mounting type (2-SMD Gull Wing surface mount). Electrical parameters (voltage and current) are application-specific and do not prevent substitution if circuit design is adjusted accordingly.

Q: Why is the MX6AWT-H1-0000-000AF6 preferred over the obsolete MX6SWT-H1-0000-000AF6?

A: The MX6AWT-H1-0000-000AF6 is the active production part in the XLamp® product line, ensuring long-term availability. It also carries RoHS compliance certification. Both parts deliver identical luminous flux and optical characteristics, making the active part the standard choice for new designs and production continuity.

Q: Are there differences in the package designation between these parts?

A: The main part uses standard 2-SMD Gull Wing packaging, while the substitute uses 2-SMD Gull Wing with Exposed Pad. The exposed pad provides improved thermal dissipation and is a standard enhancement in the MX-6 series. Physical dimensions and mounting footprint remain identical.

Q: What is the impact of the higher lumens/watt efficiency of the substitute part?

A: The MX6AWT-H1-0000-000AF6 achieves 92 lm/W compared to 76 lm/W for the main part, indicating improved energy efficiency at its rated operating point. This is a performance advantage when operating at the substitute part's specified 300mA test current, though direct comparison requires normalization to equivalent operating conditions.
