Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-A1-0000-000DF4 is determined by the following critical parameters:

Electrical Compatibility Parameters:

• Color and CCT (4750K neutral white) must match
• CRI (75 Typ) must be maintained
• Viewing angle (120°) must be preserved
• Flux output (111lm nominal) must be equivalent

Mechanical Compatibility Parameters:

• Mounting type (Surface Mount) must be identical
• Package type (2-SMD, Gull Wing) must be compatible
• Physical dimensions (5.00mm x 5.00mm footprint) must match
• Height (1.48mm max seated) must not exceed PCB clearance requirements

Thermal & Environmental Parameters:

• Thermal resistance (5°C/W) must be equivalent
• Moisture sensitivity level (2A, 4 Weeks) must be acceptable
• REACH compliance status must be maintained

The MX6AWT-A1-0000-000DF4 qualifies as a substitute based on matching color, CCT, CRI, viewing angle, mounting type, package configuration, physical dimensions, height, thermal resistance, and environmental compliance. However, significant differences exist in electrical operating parameters (voltage and current ratings), which require circuit redesign for proper implementation.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Photometric & Mechanical Compatibility):

The MX6AWT-A1-0000-000DF4 maintains identical photometric output (111lm at 4750K, CRI 75), viewing angle (120°), and mechanical form factor (5.00mm x 5.00mm, 1.48mm height, 2-SMD Gull Wing package). This part is currently in active production status, ensuring long-term availability compared to the obsolete MX6SWT-A1-0000-000DF4.

Critical Design Consideration:

The MX6AWT-A1-0000-000DF4 operates at 3.3V typical forward voltage with 300mA test current, compared to the MX6SWT-A1-0000-000DF4 at 20V and 60mA. This represents a fundamental change in electrical operating parameters. Direct pin-for-pin substitution is not possible without complete redesign of the LED driver circuit, current limiting resistors, and power supply architecture.

Compliance Advantage:

The MX6AWT-A1-0000-000DF4 carries RoHS Compliant certification, whereas the main part does not specify RoHS status. Both parts maintain REACH Unaffected status and identical moisture sensitivity levels (2A, 4 Weeks).

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000DF4 be used as a direct drop-in replacement for the MX6SWT-A1-0000-000DF4?

A: No. While both parts share identical photometric properties (111lm, 4750K, CRI 75), viewing angle (120°), and mechanical dimensions (5.00mm x 5.00mm footprint, 1.48mm height), they operate at different electrical parameters. The MX6SWT operates at 20V/60mA, while the MX6AWT operates at 3.3V/300mA. Circuit redesign is required, including modifications to the LED driver, current limiting network, and power supply.

Q: Are the package types compatible?

A: Both parts use 2-SMD Gull Wing surface mount packages with identical 5.00mm x 5.00mm footprints and 1.48mm maximum seated heights. The MX6AWT-A1-0000-000DF4 includes an exposed pad, which provides improved thermal performance. PCB layout compatibility depends on whether the original design accommodates the exposed pad configuration.

Q: What is the impact of the different test currents (60mA vs. 300mA)?

A: The test current defines the operating point at which photometric specifications are measured. The MX6AWT-A1-0000-000DF4 achieves the same 111lm output at 300mA as the MX6SWT achieves at 60mA, indicating different internal LED chip configurations. This difference necessitates complete redesign of the current limiting circuit.

Q: Does the MX6AWT-A1-0000-000DF4 offer any advantages?

A: The MX6AWT-A1-0000-000DF4 is in active production (vs. obsolete status), carries RoHS Compliant certification, and achieves higher luminous efficacy (112 lm/W vs. 93 lm/W). The exposed pad provides superior thermal management. However, these advantages require circuit redesign to realize.

Q: Are there any moisture sensitivity or environmental compliance concerns?

A: Both parts carry identical Moisture Sensitivity Level (2A, 4 Weeks) and REACH Unaffected status. The MX6AWT-A1-0000-000DF4 provides additional RoHS Compliant certification. No environmental compliance barriers exist for substitution.

Q: What is the availability status of each part?

A: The MX6SWT-A1-0000-000DF4 is obsolete with 1135 pcs in current inventory. The MX6AWT-A1-0000-000DF4 is active production with 799 pcs in current inventory and ongoing supply assurance.
