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

Part Overview

The MX6SWT-H1-0000-000FDZ is a CreeLED XLamp® MX-6S cool white LED (5000K) designed for surface mount applications requiring high luminous efficacy and compact form factor. This part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production and design continuity. The MX-6S series has been superseded by the MX-6 series, which maintains core optical and mechanical compatibility while offering improved electrical characteristics and active product status.

Substitute Part Grouping Explanation

Substitution of the MX6SWT-H1-0000-000FDZ is limited to parts meeting the following criteria:

Mandatory Matching Parameters:

Color and CCT: White, Cool 5000K
Viewing Angle: 120°
Package Type: 2-SMD, Gull Wing configuration
Physical Dimensions: 5.00mm × 5.00mm footprint
Mounting Type: Surface Mount
Thermal Resistance: 5°C/W
CRI: 80

Allowable Variation Parameters:

Forward Voltage (Vf): May differ based on circuit design requirements
Test Current: May differ based on application requirements
Luminous Flux: Acceptable within typical manufacturing tolerance ranges
Luminous Efficacy: Secondary consideration; flux and current determine suitability

The MX6AWT-H1-0000-000DDZ qualifies as a substitute based on identical optical properties (color, CCT, viewing angle, CRI), identical mechanical compatibility (package, dimensions, thermal resistance), and maintained surface mount configuration. Electrical parameter differences (3.3V vs. 20V forward voltage; 300mA vs. 60mA test current) require circuit redesign but do not preclude substitution at the component level.

Engineering Selection Recommendations

The MX6AWT-H1-0000-000DDZ is the designated substitute for the obsolete MX6SWT-H1-0000-000FDZ. Selection is justified on the following basis:

Product Status: The substitute part maintains active product status with CreeLED, ensuring continued availability and manufacturing support. The main part's obsolete classification necessitates transition to an alternative.

Optical Compatibility: Both parts deliver identical color temperature (5000K), viewing angle (120°), and color rendering index (80), ensuring equivalent light distribution and color accuracy in end-use applications.

Mechanical Compatibility: Identical footprint (5.00mm × 5.00mm), height (1.48mm), and thermal resistance (5°C/W) permit direct PCB layout reuse without redesign of thermal management structures.

Compliance: The substitute part carries RoHS Compliant certification, meeting regulatory requirements for restricted substances. Both parts maintain REACH Unaffected status.

Electrical Redesign Required: The substitute operates at 3.3V forward voltage and 300mA test current, compared to the main part's 20V and 60mA. Circuit redesign is mandatory to accommodate these electrical differences. The substitute's higher maximum current rating (1A vs. 175mA) provides additional design margin in current-limited applications.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000DDZ be used as a direct drop-in replacement without circuit modification?

A: No. While the parts are mechanically and optically compatible, the electrical parameters differ significantly. The substitute requires 3.3V forward voltage and operates at 300mA test current, versus the main part's 20V and 60mA. Circuit redesign of the LED driver and current-limiting network is mandatory.

Q: Are the physical dimensions identical between the two parts?

A: Yes. Both parts share identical footprint (5.00mm × 5.00mm), seated height (1.48mm), and thermal resistance (5°C/W). PCB layout and thermal design do not require modification.

Q: What is the significance of the "Exposed Pad" designation in the substitute part's package?

A: The exposed pad in the MX6AWT-H1-0000-000DDZ provides enhanced thermal coupling to the PCB, improving heat dissipation. This is a design improvement over the standard gull wing package and does not affect compatibility or substitution suitability.

Q: Will the substitute part produce the same light output?

A: The substitute produces 111lm at 25°C compared to the main part's 126lm. This represents an 11.9% reduction in absolute flux. Both parts maintain identical color temperature (5000K) and viewing angle (120°). Application-specific requirements determine whether this flux difference is acceptable.

Q: Are moisture sensitivity and storage requirements the same?

A: Yes. Both parts carry MSL 2A rating (4 weeks), requiring identical moisture control and storage protocols.

Q: What compliance certifications apply to the substitute part?

A: The substitute is RoHS Compliant and REACH Unaffected. Both parts maintain EAR99 export classification and identical HTSUS codes.
