MX6SWT-A1-0000-000BF5 Equivalent & Substitute Parts

Part Overview

The MX6SWT-A1-0000-000BF5 is an XLamp® MX-6S white neutral LED (4250K) manufactured by CreeLED, Inc., designed for surface mount applications requiring 20V forward voltage at 60mA test current. This part is classified as obsolete, making identification of suitable substitute components essential for ongoing production and maintenance applications. The XLamp® MX-6S series has been superseded by newer generations within the XLamp® product line, necessitating equivalent part selection based on electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-A1-0000-000BF5 is determined by the following critical parameters:

Color and Correlated Color Temperature (CCT): Both the main part and substitute must maintain white neutral 4250K specification to ensure consistent color output in lighting applications.

Viewing Angle: The 120° viewing angle is a fixed optical characteristic that must be preserved across substitute selection.

Package and Mounting: Both parts must use 2-SMD, Gull Wing surface mount configuration with identical physical dimensions (5.00mm x 5.00mm footprint, 1.48mm maximum seated height) to ensure PCB compatibility without redesign.

Thermal Resistance: The 5°C/W thermal resistance specification must be maintained to ensure equivalent thermal performance in the application circuit.

Moisture Sensitivity Level: MSL 2A classification must be preserved to maintain handling and storage requirements consistency.

The MX6AWT-H1-R250-000BF5 qualifies as a substitute based on matching these core parameters, despite differences in forward voltage, test current, and efficiency characteristics. These electrical differences reflect the evolution from the MX-6S to the MX-6 series architecture and do not preclude substitution when circuit design accommodates the new electrical specifications.

Engineering Selection Recommendations

The MX6AWT-H1-R250-000BF5 is the designated substitute for the obsolete MX6SWT-A1-0000-000BF5. Selection of this substitute is supported by the following factors:

Product Status: The substitute part maintains active product status with CreeLED, Inc., ensuring continued availability and supply chain reliability compared to the obsolete main part.

Compliance and Certifications: The MX6AWT-H1-R250-000BF5 carries RoHS Compliant certification, meeting current regulatory requirements for electronic components in regulated markets. Both parts maintain REACH Unaffected and EAR99 ECCN classifications.

Optical and Thermal Equivalence: Identical flux output (97lm), CRI (80), viewing angle (120°), and thermal resistance (5°C/W) ensure optical and thermal performance parity in the application.

Physical Compatibility: Matching footprint dimensions (5.00mm x 5.00mm) and seated height (1.48mm) permit direct PCB layout reuse without redesign.

Electrical Redesign Requirement: Circuit design modification is necessary to accommodate the shift from 20V/60mA (MX6SWT-A1-0000-000BF5) to 3.3V/300mA (MX6AWT-H1-R250-000BF5) specifications. This represents a fundamental architectural change between the MX-6S and MX-6 series and requires driver circuit adjustment.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-R250-000BF5 be used as a direct drop-in replacement without circuit modification?

A: No. While the physical footprint and optical characteristics are compatible, the electrical specifications differ significantly. The substitute operates at 3.3V/300mA versus the original 20V/60mA. The LED driver circuit must be redesigned to accommodate these new specifications.

Q: Are the color and brightness characteristics identical between the main part and substitute?

A: Yes. Both parts produce white neutral 4250K light with 97lm flux output and CRI 80. The lumens/watt efficiency differs (81 lm/W vs. 98 lm/W), reflecting the MX-6 series' improved efficiency, but perceived brightness at equivalent drive current remains consistent.

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

A: The MX6AWT-H1-R250-000BF5 features an exposed thermal pad on the package underside, improving heat dissipation compared to the standard gull wing package. This enhancement supports the higher current operation (300mA test vs. 60mA) while maintaining the same 5°C/W thermal resistance specification.

Q: Does the substitute part require different PCB layout considerations?

A: The physical footprint remains identical (5.00mm x 5.00mm), so existing PCB layouts do not require modification for component placement. However, the exposed pad on the substitute should be connected to a thermal ground plane for optimal heat dissipation. Trace routing for power delivery must be redesigned to handle the increased current requirements.

Q: What is the impact of the substitute's higher maximum current rating (1A vs. 175mA)?

A: The MX6AWT-H1-R250-000BF5 supports higher absolute maximum current, providing design margin for applications requiring increased brightness or thermal headroom. The test current specification (300mA) remains the reference point for optical and efficiency ratings.

Q: Are there any supply chain or availability differences between the main part and substitute?

A: The main part (MX6SWT-A1-0000-000BF5) is obsolete and subject to limited availability. The substitute (MX6AWT-H1-R250-000BF5) maintains active product status with established supply channels, ensuring long-term component availability for production and maintenance applications.
