Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-A1-0000-000CB6 is based on the following criteria:

Mechanical Compatibility: Both the main part and substitute maintain identical 2-SMD Gull Wing package geometry, with matching footprint dimensions of 5.00mm x 5.00mm and maximum seated height of 1.48mm. This ensures direct PCB compatibility without layout modifications.

Thermal Characteristics: Both components share identical thermal resistance of 5°C/W, maintaining equivalent thermal performance in circuit applications.

Optical Properties: Both parts emit white light with identical viewing angle of 120° and matching luminous flux output of 104lm at their respective test currents.

Moisture Sensitivity: Both components are rated MSL 2A (4 Weeks), requiring identical handling and storage protocols.

Key Differentiators: The substitute part operates at significantly lower forward voltage (3.3V vs. 20V) and higher test current (300mA vs. 60mA), resulting in improved luminous efficacy (105 lm/W vs. 87 lm/W). The substitute is Active status with RoHS compliance, whereas the main part is Obsolete.

Engineering Selection Recommendations

The MX6AWT-A1-0000-000CB3 is the designated substitute for the obsolete MX6SWT-A1-0000-000CB6. Selection is based on the following factors:

Product Status: The substitute is Active status, ensuring long-term availability and manufacturing support, whereas the main part is Obsolete and subject to discontinuation.

Compliance: The MX6AWT-A1-0000-000CB3 carries RoHS Compliant certification, meeting current regulatory requirements for electronic component manufacturing and distribution.

Mechanical Compatibility: Identical package footprint and thermal characteristics enable direct substitution without PCB redesign.

Electrical Redesign Requirement: Circuit design modification is necessary due to the significant forward voltage difference (3.3V vs. 20V). The substitute requires a different current-limiting resistor or driver circuit configuration. The higher maximum current rating (1A vs. 175mA) provides additional design margin.

Performance Improvement: The substitute delivers superior luminous efficacy (105 lm/W vs. 87 lm/W) while maintaining equivalent luminous output at the specified test current.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000CB3 be used as a direct drop-in replacement without circuit modification?

A: No. While the mechanical footprint and thermal characteristics are identical, the forward voltage differs significantly (3.3V vs. 20V). The current-limiting resistor or driver circuit must be recalculated for the new operating voltage to maintain proper LED current and prevent component damage.

Q: What is the difference between the 2-SMD Gull Wing and 2-SMD Gull Wing Exposed Pad packages?

A: Both packages share identical external dimensions and footprint. The Exposed Pad variant in the substitute part provides an additional thermal connection point to the PCB, improving heat dissipation. This is a mechanical enhancement that does not affect electrical compatibility.

Q: Are both parts suitable for the same application environments?

A: Both components share identical Moisture Sensitivity Level (MSL 2A, 4 Weeks) and thermal resistance (5°C/W), indicating equivalent environmental handling and thermal performance requirements. However, the electrical operating parameters differ, requiring circuit-level evaluation for specific application suitability.

Q: Why does the substitute part have a higher maximum current rating?

A: The MX6AWT-A1-0000-000CB3 operates at lower forward voltage (3.3V) and is designed for higher current operation (300mA test current vs. 60mA). The 1A maximum rating reflects the broader operating range of the newer XLamp® MX-6 series compared to the obsolete MX-6S variant.

Q: Is the substitute part available in the same packaging format?

A: The substitute is supplied in Tape & Reel (TR) format, which is standard for production environments. The original part packaging format was not specified in the available data.
