Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MX6SWT-H1-0000-000CA3 is determined by the following critical parameters:

Color and CCT Match: Both the main part and substitute must maintain White, Neutral 4300K color specification to ensure consistent lighting output and color rendering in the application.

Luminous Flux Compatibility: The substitute must deliver equivalent luminous flux output (104lm nominal range) to maintain brightness levels in the end application.

Viewing Angle: The 120° viewing angle must be preserved to ensure consistent light distribution characteristics.

Package Geometry: Both parts utilize identical 5.00mm x 5.00mm 2-SMD gull wing surface mount packages with 1.48mm maximum seated height, ensuring PCB layout and assembly compatibility.

Thermal Characteristics: The 5°C/W thermal resistance specification must be maintained for consistent thermal performance.

Moisture Sensitivity: MSL 2A (4 Weeks) classification must be matched for equivalent handling and storage requirements.

The primary distinction between the main part and its substitute lies in the electrical operating parameters (forward voltage and test current), which reflect different internal LED configurations within the same package form factor and optical specifications.

Engineering Selection Recommendations

The MX6AWT-H1-0000-000CA3 is the designated substitute for the obsolete MX6SWT-H1-0000-000CA3. Selection of this substitute is supported by the following engineering factors:

Product Status: The substitute part maintains Active product status, ensuring ongoing availability and manufacturer support, whereas the main part is classified as Obsolete.

Compliance and Certifications: The substitute part carries RoHS Compliant certification, providing enhanced environmental compliance compared to the main part specification. Both parts maintain REACH Unaffected and EAR99 ECCN classifications.

Optical and Thermal Equivalence: Both parts deliver identical luminous flux (104lm), color temperature (4300K), color rendering index (80), viewing angle (120°), and thermal resistance (5°C/W), ensuring equivalent optical and thermal performance in the application.

Package Compatibility: Both parts utilize identical 5.00mm x 5.00mm surface mount packages with 1.48mm maximum seated height. The substitute features an exposed pad variant of the 2-SMD gull wing package, which provides improved thermal dissipation characteristics.

Electrical Parameter Differences: The substitute operates at 3.3V forward voltage with 300mA test current, compared to the main part's 20V and 60mA specifications. Circuit design must accommodate these electrical parameter differences through appropriate current limiting and voltage regulation.

Efficiency Improvement: The substitute demonstrates 105 lm/W efficiency at its test current, compared to 87 lm/W for the main part, indicating improved energy conversion at the substitute's operating point.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000CA3 be used as a direct drop-in replacement for the MX6SWT-H1-0000-000CA3?

A: The substitute part is optically and thermally equivalent but requires circuit redesign due to different electrical operating parameters. The main part operates at 20V/60mA, while the substitute operates at 3.3V/300mA. Current limiting and voltage regulation circuits must be modified accordingly. Physical package compatibility is maintained.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching color (White, Neutral), CCT (4300K), luminous flux (104lm), viewing angle (120°), package geometry (5.00mm x 5.00mm 2-SMD gull wing), thermal resistance (5°C/W), and moisture sensitivity level (2A). These parameters ensure equivalent optical, thermal, and handling characteristics.

Q: Does the exposed pad variant in the substitute part affect PCB layout?

A: The substitute's 2-SMD gull wing exposed pad package provides improved thermal dissipation compared to the standard gull wing package. PCB layout should include thermal via patterns connected to the exposed pad to maximize heat transfer to the PCB substrate, particularly in high-current applications.

Q: Are there compliance differences between the main part and substitute?

A: The substitute part carries RoHS Compliant certification, whereas the main part does not specify RoHS status. Both parts maintain REACH Unaffected and EAR99 ECCN classifications. The substitute's RoHS compliance provides enhanced environmental regulatory alignment.

Q: What is the impact of the different test current specifications?

A: The main part is characterized at 60mA/20V, while the substitute is characterized at 300mA/3.3V. Both deliver equivalent luminous flux (104lm) at their respective test currents. The substitute demonstrates higher efficiency (105 lm/W vs. 87 lm/W) at its operating point. Circuit design must account for these different electrical operating conditions.

Q: How do the maximum current ratings differ?

A: The main part supports maximum current of 175mA, while the substitute supports maximum current of 1A. The substitute's higher current rating provides greater operational headroom in the application circuit.

Q: Is the packaging format (Tape & Reel) for the substitute compatible with standard pick-and-place assembly?

A: Yes. Tape & Reel (TR) packaging is standard for automated surface mount assembly processes. The 5.00mm x 5.00mm package dimensions and gull wing lead configuration are compatible with standard pick-and-place equipment.
