Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-A1-R250-000BAA is a direct mechanical and optical substitute for the obsolete MX6SWT-A1-0000-000CAA. Both components share identical footprint dimensions (5.00 mm × 5.00 mm), height (1.48 mm), thermal resistance (5°C/W), color temperature (2700K), CRI (80), and viewing angle (120°).

Key Advantages of the Substitute:

• Active product status ensures long-term availability and supply chain continuity
• RoHS compliance certification provides regulatory alignment
• Improved lumens/watt efficiency (98 lm/W vs. 87 lm/W)
• Higher maximum current rating (1000 mA vs. 175 mA) allows greater design flexibility

Critical Design Consideration: The substitute operates at 3.3V forward voltage with a 300 mA test current, compared to the main part's 20V and 60 mA. Circuit designs must be modified to accommodate this lower voltage and higher current requirement. The flux output difference (97 lm vs. 104 lm) is within acceptable tolerance for warm white 2700K LED applications.

The exposed pad configuration on the substitute provides enhanced thermal management compared to the standard gull wing package, supporting improved heat dissipation in high-current applications.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-R250-000BAA be used as a direct drop-in replacement for the MX6SWT-A1-0000-000CAA?

A: Mechanically and optically, yes. Both components have identical footprints (5.00 mm × 5.00 mm), heights (1.48 mm), and thermal characteristics. However, the electrical requirements differ significantly: the substitute operates at 3.3V/300 mA versus the original's 20V/60 mA. Circuit redesign is required to accommodate this voltage and current difference.

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

A: The exposed pad on the MX6AWT-A1-R250-000BAA provides direct thermal contact to the PCB, improving heat dissipation. This is beneficial for applications requiring sustained operation at higher currents or in thermally constrained environments.

Q: Are there any compliance differences between the two parts?

A: The substitute (MX6AWT-A1-R250-000BAA) carries RoHS compliance certification, while the main part's RoHS status is not specified. Both parts are REACH Unaffected and classified as EAR99 for export control purposes.

Q: How do the flux outputs compare?

A: The main part delivers 104 lm at 25°C (100–107 lm range), while the substitute delivers 97 lm (94–100 lm range). This 7 lm difference represents approximately 7% lower output. For applications requiring precise lumen specifications, this variance must be evaluated against system requirements.

Q: What packaging formats are available?

A: The main part is supplied in bulk packaging. The substitute is available in Tape & Reel (TR) format, which is standard for automated assembly processes and offers improved handling and traceability for production environments.

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

A: Both components have identical thermal resistance ratings (5°C/W) and MSL classifications (2A, 4 Weeks). However, the substitute's exposed pad design provides superior thermal performance in high-current applications, making it preferable for thermally demanding designs.
