Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-A1-0000-000DF7 is determined by the following critical parameters:

Color and Correlated Color Temperature (CCT): Both the main part and substitute must maintain 3250K warm white specification to preserve color consistency in end-use applications.

Viewing Angle: The 120° viewing angle is a fixed optical characteristic that must be matched.

Package and Mounting: Both parts utilize 2-SMD, Gull Wing surface mount packages with identical footprint dimensions (5.00 mm × 5.00 mm) and maximum seated height (1.48 mm), ensuring PCB compatibility without redesign.

Thermal Resistance: The 5°C/W thermal resistance specification must be maintained to ensure thermal management performance.

Moisture Sensitivity Level: Both parts carry MSL 2A (4 Weeks) classification, indicating identical moisture handling requirements.

The identified substitute, MX6AWT-01-0000-000DA7, shares these core mechanical and optical parameters. However, electrical characteristics differ significantly: the substitute operates at 3.3V forward voltage with 300 mA test current, compared to the main part's 20V and 60 mA specification. This electrical difference reflects the transition from the MX-6S to the MX-6 series architecture and requires circuit-level evaluation for compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-01-0000-000DA7 is the identified substitute for the obsolete MX6SWT-A1-0000-000DF7. Both parts maintain identical color temperature (3250K), optical characteristics (120° viewing angle), and physical footprint (5.00 mm × 5.00 mm, 1.48 mm max height), ensuring mechanical compatibility on existing PCB layouts.

The substitute part carries Active product status, ensuring ongoing availability and supply chain continuity. The MX6AWT-01-0000-000DA7 is RoHS Compliant and supplied in Tape & Reel packaging, meeting modern manufacturing and environmental compliance requirements.

Critical consideration: The electrical architecture differs between the two parts. The main part operates at 20V forward voltage with 60 mA test current, while the substitute operates at 3.3V with 300 mA test current. This represents a fundamental shift from the MX-6S to MX-6 series design. Circuit redesign is required to accommodate the different voltage and current specifications. The substitute demonstrates improved efficiency (112 lm/W versus 93 lm/W), but CRI specification is not provided for the substitute part.

Selection of the MX6AWT-01-0000-000DA7 requires electrical circuit modification and is appropriate only when design flexibility permits voltage and current architecture changes.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-01-0000-000DA7 be used as a direct drop-in replacement for the MX6SWT-A1-0000-000DF7?

A: No. While both parts share identical physical dimensions (5.00 mm × 5.00 mm footprint, 1.48 mm max height) and optical characteristics (3250K, 120° viewing angle), the electrical specifications differ fundamentally. The main part requires 20V forward voltage at 60 mA test current, while the substitute operates at 3.3V and 300 mA. Circuit-level modifications to voltage regulation and current limiting are necessary.

Q: Are the package types compatible?

A: Both parts use 2-SMD, Gull Wing surface mount packages with identical footprint dimensions. The main part is supplied loose, while the substitute is supplied in Tape & Reel (TR) format. PCB assembly equipment compatibility depends on your specific manufacturing process. The substitute includes an exposed pad, which may provide improved thermal performance in applications requiring enhanced heat dissipation.

Q: What is the difference in color rendering between these parts?

A: Both parts are specified as warm white at 3250K. The main part specifies CRI (Color Rendering Index) of 80 (Typ). The substitute part does not provide a CRI specification in the available data. If color rendering index is a critical requirement for your application, this parameter should be confirmed with the manufacturer before substitution.

Q: Why is the main part obsolete?

A: The MX6SWT-A1-0000-000DF7 belongs to the XLamp® MX-6S series, which has been superseded by the newer XLamp® MX-6 series. The MX6AWT-01-0000-000DA7 represents the current generation equivalent within the warm white 3250K product line.

Q: What are the moisture handling requirements?

A: Both parts carry Moisture Sensitivity Level (MSL) 2A (4 Weeks) classification. This indicates that both parts must be stored in controlled humidity environments and have a floor life of 4 weeks after opening the moisture barrier bag. Identical moisture handling procedures apply to both parts.

Q: Are there compliance or regulatory differences?

A: Both parts are REACH Unaffected and classified as EAR99 for export control purposes. The substitute part is RoHS Compliant, while RoHS status is not specified for the main part. Both parts meet identical environmental and regulatory classifications for the specified parameters.
