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

Part Overview

The MX6SWT-H1-0000-000DDZ is an XLamp® MX-6S white LED with cool color temperature (5000K) designed for surface mount applications. This part is classified as obsolete, making identification of suitable substitute components essential for ongoing production and maintenance requirements. The MX-6S series has been superseded by the active MX-6 series, which maintains compatibility across key electrical and mechanical parameters while offering improved performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

The MX6AWT-H1-0000-000DDZ qualifies as a substitute based on the following alignment of critical parameters:

Matching Parameters:

• Color specification: White, Cool 5000K (identical CCT)
• Luminous flux @ 25°C: 111lm (107lm ~ 114lm) (identical range)
• Viewing angle: 120° (identical)
• Mounting type: Surface Mount (identical)
• Physical footprint: 5.00mm x 5.00mm (identical)
• Height - Seated (Max): 0.058" (1.48mm) (identical)
• Thermal Resistance: 5°C/W (identical)
• CRI: 80 (identical)
• MSL: 2A (4 Weeks) (identical)
• Package style: 2-SMD, Gull Wing (compatible form factor)

Differing Parameters:

• Voltage - Forward (Vf): MX6SWT operates at 20V typical; MX6AWT operates at 3.3V typical
• Current - Test: MX6SWT at 60mA; MX6AWT at 300mA
• Current - Max: MX6SWT at 175mA; MX6AWT at 1A
• Lumens/Watt: MX6SWT at 93 lm/W; MX6AWT at 112 lm/W
• Product Status: MX6SWT is obsolete; MX6AWT is active
• Packaging: MX6SWT in bulk; MX6AWT in Tape & Reel (TR)

Substitution is valid for applications where the lower forward voltage (3.3V vs. 20V) and higher current rating (300mA test vs. 60mA test) of the MX6AWT are compatible with circuit design requirements.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-0000-000DDZ is the designated substitute for the obsolete MX6SWT-H1-0000-000DDZ. Selection of the MX6AWT is supported by:

• Active product status with ongoing manufacturer support and availability
• RoHS compliance certification (MX6AWT)
• Identical optical and thermal characteristics (luminous flux, viewing angle, thermal resistance)
• Identical color specification and CRI rating
• Compatible physical footprint and mounting interface
• Identical regulatory classification (REACH Unaffected, EAR99)

Circuit design modifications are required to accommodate the different electrical characteristics: the MX6AWT operates at 3.3V forward voltage with 300mA test current, compared to the MX6SWT's 20V forward voltage with 60mA test current. Driver and current-limiting circuitry must be redesigned accordingly.

Frequently Asked Questions (FAQ)

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

A: The MX6AWT is mechanically compatible (identical footprint, height, and mounting type) but requires circuit redesign. The forward voltage differs significantly (3.3V vs. 20V), necessitating modification of the LED driver and current-limiting circuitry. Optical output remains equivalent.

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

A: The primary differences are forward voltage (3.3V vs. 20V), test current (300mA vs. 60mA), and maximum current rating (1A vs. 175mA). The MX6AWT also features an exposed pad variant of the 2-SMD Gull Wing package. Optical characteristics, color temperature, and thermal properties are identical.

Q: Why is the MX6SWT classified as obsolete?

A: The MX6SWT belongs to the XLamp® MX-6S series, which has been superseded by the active XLamp® MX-6 series. The MX6AWT represents the current generation equivalent with improved efficiency (112 lm/W vs. 93 lm/W).

Q: Are there any compliance or regulatory differences?

A: Both parts share identical REACH and ECCN classifications (REACH Unaffected, EAR99). The MX6AWT carries RoHS compliance certification, whereas the MX6SWT does not list this certification in the provided specifications.

Q: What is the significance of the exposed pad in the MX6AWT package?

A: The exposed pad in the 2-SMD Gull Wing Exposed Pad package improves thermal dissipation and electrical performance. This is a design enhancement in the MX-6 series compared to the MX-6S series.

Q: Can I use the MX6AWT in a 20V circuit designed for the MX6SWT?

A: No. The MX6AWT's 3.3V forward voltage is incompatible with a 20V circuit. The LED driver and current-limiting resistor or active current source must be redesigned for the lower voltage and higher current requirements of the MX6AWT.
