Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MX6SWT-H1-R250-000BA6 is determined by the following critical parameters:

Color and Correlated Color Temperature (CCT): Both the main part and substitute must maintain White, Warm 3500K specification to ensure consistent color output in end-use applications.

Luminous Flux Output: The substitute must deliver equivalent light output at its specified test current. The MX6SWT-H1-R250-000BA6 produces 97 lm at 60mA test current; substitutes must maintain comparable flux performance.

Color Rendering Index (CRI): A CRI of 80 is required to preserve color fidelity in applications where this specification is critical.

Viewing Angle: The 120° viewing angle must be maintained for optical consistency.

Package and Mounting: Surface mount 2-SMD Gull Wing configuration with identical footprint dimensions (5.00mm × 5.00mm) and maximum seated height (1.48mm) ensures mechanical compatibility.

Thermal Characteristics: Thermal resistance of 5°C/W must be preserved to maintain thermal management performance.

Regulatory Compliance: REACH Unaffected status and EAR99 ECCN classification must be maintained.

The MX6AWT-H1-R250-000BA6 qualifies as a substitute based on matching color specification, flux output, CRI, viewing angle, package dimensions, thermal resistance, and regulatory status.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-R250-000BA6 is the qualified substitute for the obsolete MX6SWT-H1-R250-000BA6. Selection of this substitute is supported by the following factors:

Product Status: The MX6AWT-H1-R250-000BA6 maintains Active product status, ensuring ongoing availability and manufacturer support, whereas the main part is Obsolete.

Regulatory Compliance: Both parts maintain REACH Unaffected status and EAR99 ECCN classification. The substitute additionally carries RoHS Compliant certification, providing enhanced environmental compliance for applications subject to RoHS requirements.

Optical and Thermal Equivalence: Both parts deliver identical luminous flux (97 lm), maintain the same CRI (80), viewing angle (120°), and thermal resistance (5°C/W), ensuring functional equivalence in optical performance and thermal management.

Mechanical Compatibility: Identical footprint dimensions (5.00mm × 5.00mm) and maximum seated height (1.48mm) confirm direct mechanical compatibility on existing PCB layouts.

Electrical Differences: The substitute operates at 3.3V forward voltage with a 300mA test current, compared to the main part's 20V and 60mA specification. Circuit design modifications are required to accommodate these electrical parameter differences. The substitute demonstrates improved efficiency (98 lm/W versus 81 lm/W) at its specified operating point.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-R250-000BA6 be used as a direct drop-in replacement for the MX6SWT-H1-R250-000BA6?

A: Mechanical and optical compatibility is confirmed. However, the substitute requires circuit design modifications due to different forward voltage (3.3V versus 20V) and test current (300mA versus 60mA) specifications. PCB layout and current-limiting circuitry must be redesigned accordingly.

Q: Are the luminous flux outputs equivalent between these parts?

A: Yes. Both parts deliver 97 lumens (94–100 lm range) at their respective test currents and 25°C ambient temperature, ensuring equivalent light output performance.

Q: What is the difference between the package designations "2-SMD, Gull Wing" and "2-SMD, Gull Wing Exposed Pad"?

A: Both packages share identical footprint dimensions and mounting characteristics. The exposed pad on the substitute provides enhanced thermal dissipation capability, which may improve thermal performance in high-power applications.

Q: Does the substitute meet RoHS requirements?

A: Yes. The MX6AWT-H1-R250-000BA6 carries RoHS Compliant certification. The main part does not specify RoHS status.

Q: Are both parts available in the same packaging format?

A: The main part packaging is not specified. The substitute is available in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly.

Q: What is the impact of the efficiency difference (81 lm/W versus 98 lm/W)?

A: The substitute demonstrates higher efficiency at its specified operating point (300mA, 3.3V). This reflects the different electrical operating conditions and does not indicate superior or inferior performance; efficiency comparisons are valid only at equivalent operating currents and voltages.

Q: Are the thermal characteristics identical?

A: Yes. Both parts maintain a thermal resistance of 5°C/W, ensuring equivalent thermal management performance in equivalent thermal environments.
