Key Parameters

Substitute Part Grouping Explanation

The MX6AWT-A1-0000-000BA4 is identified as a substitute based on the following matching parameters:

Electrical Compatibility Criteria:

• Color: White, Neutral (4000K) — identical CCT specification
• CRI (Color Rendering Index): 80 (Typ) — matching color rendering performance
• Viewing Angle: 120° — identical optical characteristics
• Flux @ 25°C: 97lm (94lm ~ 100lm) — equivalent luminous output

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount — same assembly method
• Package / Case: 2-SMD, Gull Wing — compatible footprint and lead configuration
• Size / Dimension: 0.197" L x 0.197" W (5.00mm x 5.00mm) — identical physical dimensions
• Height - Seated (Max): 0.058" (1.48mm) — matching height profile
• Thermal Resistance of Package: 5°C/W — identical thermal characteristics
• Moisture Sensitivity Level (MSL): 2A (4 Weeks) — matching moisture handling requirements

Key Difference: The substitute operates at 3.3V forward voltage with 300mA test current, compared to the main part's 20V/60mA specification. This represents a fundamental electrical difference requiring circuit redesign for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MX6SWT-A1-0000-000BA4 is obsolete, while the MX6AWT-A1-0000-000BA4 is active. For new designs or long-term production continuity, the active substitute is the appropriate selection.

Compliance Advantage: The MX6AWT-A1-0000-000BA4 carries RoHS Compliant certification, whereas RoHS status is not specified for the obsolete MX6SWT-A1-0000-000BA4. This provides regulatory advantage for applications subject to RoHS requirements.

Electrical Redesign Requirement: Direct substitution requires circuit modification. The substitute operates at 3.3V/300mA versus the original 20V/60mA. Power supply, current limiting, and thermal management designs must be adjusted accordingly. The substitute delivers higher efficiency (98 lm/W vs. 81 lm/W) and supports higher maximum current (1A vs. 175mA).

Mechanical Compatibility: Both parts share identical physical dimensions, thermal characteristics, and moisture sensitivity ratings. The substitute features an exposed pad variant of the 2-SMD Gull Wing package, which may provide improved thermal performance in PCB designs incorporating thermal vias.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000BA4 be used as a direct drop-in replacement for the MX6SWT-A1-0000-000BA4?

A: No. While both parts share identical optical characteristics (4000K, 97lm, 120° viewing angle, 80 CRI) and mechanical dimensions, the forward voltage and current specifications differ fundamentally (20V/60mA vs. 3.3V/300mA). Circuit redesign is required for electrical compatibility.

Q: Are the physical footprints identical?

A: Yes. Both parts are 5.00mm x 5.00mm with 1.48mm maximum seated height. The package designation differs slightly (Gull Wing vs. Gull Wing Exposed Pad), but the footprint and lead configuration are compatible for PCB layout purposes.

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

A: The exposed pad on the MX6AWT-A1-0000-000BA4 provides direct thermal contact to the PCB. This improves heat dissipation compared to the standard Gull Wing package. Thermal vias connected to the exposed pad enhance thermal management in high-power applications.

Q: Why is the substitute more efficient?

A: The MX6AWT-A1-0000-000BA4 delivers 98 lm/W compared to 81 lm/W for the MX6SWT-A1-0000-000BA4. Both produce 97lm at their respective test currents, but the substitute achieves this output at lower power consumption due to its lower forward voltage and optimized die design.

Q: Is the substitute RoHS compliant?

A: Yes. The MX6AWT-A1-0000-000BA4 is RoHS Compliant. RoHS status is not specified for the obsolete MX6SWT-A1-0000-000BA4.

Q: What is the maximum current rating for each part?

A: The MX6SWT-A1-0000-000BA4 supports 175mA maximum current. The MX6AWT-A1-0000-000BA4 supports 1A maximum current, providing greater headroom for pulsed or transient operation.
