Key Parameters

Substitute Part Grouping Explanation

The MX6AWT-H1-0000-000AZ8 qualifies as a functional equivalent based on the following substitution criteria:

Compatible Parameters:

• Color and CCT: Both parts emit warm white light at 2700K
• CRI: Both maintain CRI of 80
• Viewing Angle: Both provide 120° directional output
• Mounting Type: Both are surface mount with 2-SMD, Gull Wing package
• Physical Dimensions: Both measure 5.00 mm × 5.00 mm with 1.48 mm seated height
• Thermal Resistance: Both rated at 5°C/W
• MSL Rating: Both classified as 2A (4 Weeks)
• Compliance: Both REACH Unaffected and EAR99 classified

Electrical Differences: The MX6AWT operates at 3.3V forward voltage with 300 mA test current, compared to the MX6SWT's 20V at 60 mA. This represents a fundamental architecture change from the MX-6S to MX-6 series. Circuit redesign is required for voltage and current compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The MX6AWT-H1-0000-000AZ8 is the designated successor to the MX6SWT-H1-0000-000CZ8. Selection of the MX6AWT requires circuit modification to accommodate the reduced forward voltage (3.3V vs. 20V) and increased test current (300 mA vs. 60 mA). The substitute part offers active product status and RoHS compliance, providing long-term supply chain stability.

Optical Compatibility: Both parts maintain identical color temperature (2700K), CRI (80), and viewing angle (120°), ensuring equivalent light quality and distribution characteristics. Flux output differs by approximately 13% (104 lm vs. 91 lm at respective test currents), which may require optical system recalibration.

Compliance Advantage: The MX6AWT-H1-0000-000AZ8 carries explicit RoHS Compliant certification, whereas the MX6SWT status is unspecified. Both parts maintain REACH Unaffected and EAR99 classification.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000AZ8 be used as a direct drop-in replacement for the MX6SWT-H1-0000-000CZ8?

A: No. While both parts share identical physical dimensions (5.00 mm × 5.00 mm, 1.48 mm height) and optical properties (2700K, 120° viewing angle), the electrical specifications differ fundamentally. The MX6AWT operates at 3.3V with 300 mA test current, whereas the MX6SWT requires 20V at 60 mA. Circuit redesign is mandatory, including modifications to current-limiting resistors, voltage regulation, and PCB layout.

Q: Are the package types compatible?

A: Both parts use 2-SMD, Gull Wing surface mount packages with identical footprints. The MX6AWT includes an exposed pad for improved thermal management. PCB reflow profiles and solder paste specifications remain compatible.

Q: What is the flux output difference between these parts?

A: The MX6SWT produces 104 lm at 60 mA test current, while the MX6AWT produces 91 lm at 300 mA test current. This represents approximately 13% lower output on the substitute part. Optical system design may require adjustment to maintain target illumination levels.

Q: Does the MX6AWT offer better efficiency?

A: Yes. The MX6AWT achieves 92 lm/W compared to the MX6SWT's 87 lm/W, representing a 5.7% efficiency improvement. This advantage is offset by lower absolute flux output at the respective test currents.

Q: What is the significance of the exposed pad on the MX6AWT?

A: The exposed pad on the MX6AWT-H1-0000-000AZ8 provides direct thermal contact to the PCB, improving heat dissipation. This feature supports higher current operation (1 A maximum vs. 175 mA) and reduces junction temperature under sustained operation.

Q: Are moisture sensitivity levels identical?

A: Yes. Both parts carry MSL 2A (4 Weeks) rating, requiring identical storage and handling protocols. Bake-out procedures and reflow conditions remain consistent.
