Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-H1-0000-000BA9 is determined by the following critical parameters:

Color and Correlated Color Temperature (CCT): Both the main part and substitute must maintain warm white 2850K specification to ensure consistent color rendering in end-use applications.

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

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

Thermal Resistance: The 5°C/W thermal resistance rating must be maintained to preserve thermal management performance in the application circuit.

CRI (Color Rendering Index): The CRI value of 80 establishes the color fidelity requirement for warm white lighting applications.

The MX6AWT-H1-0000-000AA9 qualifies as a functional substitute based on these parameters. However, this substitute operates under significantly different electrical conditions (3.3V forward voltage, 300mA test current) compared to the main part (20V, 60mA), requiring circuit-level evaluation before implementation.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MX6SWT-H1-0000-000BA9 is classified as obsolete, while the MX6AWT-H1-0000-000AA9 maintains active product status with ongoing manufacturer support and availability. For new designs or long-term production continuity, the active substitute is the appropriate selection.

Compliance and Certification: The MX6AWT-H1-0000-000AA9 carries explicit RoHS Compliance certification, whereas the main part does not specify RoHS status. Both parts maintain REACH Unaffected status and identical ECCN/HTSUS classifications, ensuring regulatory consistency.

Electrical Redesign Requirement: Substitution of the MX6AWT-H1-0000-000AA9 requires circuit-level modification. The substitute operates at 3.3V forward voltage with 300mA test current, compared to the main part's 20V and 60mA specification. Driver circuits, current-limiting resistors, and power supply configurations must be re-evaluated and redesigned accordingly. This is not a direct pin-compatible replacement at the circuit level.

Optical and Thermal Equivalence: Both parts maintain identical viewing angle (120°), CRI (80), thermal resistance (5°C/W), and package footprint, ensuring optical performance and thermal management characteristics remain consistent within the application.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000AA9 be used as a direct replacement for the MX6SWT-H1-0000-000BA9 without circuit modification?

A: No. While both parts share identical package footprints and optical characteristics, the electrical specifications differ significantly. The substitute requires 3.3V forward voltage and 300mA test current versus the main part's 20V and 60mA. Driver circuits and current-limiting components must be redesigned.

Q: Are the package dimensions identical between these two parts?

A: Yes. Both parts utilize 2-SMD, Gull Wing packages with 5.00mm × 5.00mm footprints and 1.48mm maximum seated height. PCB layout compatibility is maintained. The substitute includes an exposed pad, which may provide improved thermal performance in applications utilizing thermal vias.

Q: What is the difference in luminous output between these parts?

A: The main part produces 97lm at 25°C (test current 60mA), while the substitute produces 91lm at 25°C (test current 300mA). The difference reflects operation at different current levels. The substitute achieves higher luminous efficacy (92 lm/W versus 81 lm/W) due to its lower forward voltage and optimized design.

Q: Does the substitute meet RoHS requirements?

A: Yes. The MX6AWT-H1-0000-000AA9 is explicitly RoHS Compliant. The main part does not specify RoHS status. Both parts maintain REACH Unaffected classification.

Q: What is the significance of the exposed pad on the substitute part?

A: The MX6AWT-H1-0000-000AA9 features a 2-SMD, Gull Wing Exposed Pad package, compared to the standard 2-SMD, Gull Wing package of the main part. The exposed pad provides an additional thermal path to the PCB, enabling improved heat dissipation when connected via thermal vias. This is beneficial in high-power or thermally constrained applications.

Q: Are both parts suitable for the same moisture sensitivity handling procedures?

A: Yes. Both parts carry identical MSL (Moisture Sensitivity Level) ratings of 2A (4 Weeks), requiring identical storage and handling protocols.
