Key Parameters

Substitute Part Grouping Explanation

The MX6AWT-H1-0000-000AAA (XLamp® MX-6 series) qualifies as a functional substitute based on the following alignment of critical parameters:

Matching Parameters:

• Color and CCT: Both White, Warm 2700K
• CRI: Both 80
• Viewing Angle: Both 120°
• Package / Case: Both 2-SMD, Gull Wing configuration
• Physical Dimensions: Both 5.00mm × 5.00mm footprint
• Height - Seated (Max): Both 1.48mm
• Thermal Resistance: Both 5°C/W
• Mounting Type: Both Surface Mount
• MSL: Both 2A (4 Weeks)
• REACH Status: Both REACH Unaffected

Differing Parameters (Design Considerations):

• Series: MX-6S (obsolete) vs. MX-6 (active)
• Forward Voltage: 20V vs. 3.3V
• Test Current: 60mA vs. 300mA
• Flux Output: 97 lm vs. 91 lm
• Lumens/Watt: 81 lm/W vs. 92 lm/W
• Maximum Current: 175mA vs. 1A
• Product Status: Obsolete vs. Active
• Packaging: Bulk vs. Tape & Reel (TR)
• RoHS Status: Not specified vs. RoHS Compliant

The MX-6 operates at significantly lower forward voltage (3.3V) and higher test current (300mA) compared to the MX-6S, resulting in different power delivery characteristics. The MX-6 is an active product with RoHS compliance certification, whereas the MX-6S is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-0000-000AAA is the designated substitute for the obsolete MX6SWT-H1-0000-000BAA based on product status and regulatory compliance. The MX-6 is an active product with RoHS compliance certification, ensuring ongoing availability and regulatory alignment for new designs and production continuity.

Circuit design modifications are required due to the significant difference in forward voltage (20V to 3.3V) and test current (60mA to 300mA). The power supply and current-limiting resistor or driver circuit must be redesigned to accommodate the MX-6's lower voltage and higher current characteristics. The MX-6 delivers superior lumens-per-watt efficiency (92 lm/W vs. 81 lm/W), resulting in lower power dissipation at equivalent light output.

Both parts maintain identical viewing angle (120°), color temperature (2700K), CRI (80), thermal resistance (5°C/W), and physical footprint (5.00mm × 5.00mm). The MX-6 features an exposed pad variant of the 2-SMD Gull Wing package, which may provide improved thermal management in high-power applications.

Frequently Asked Questions (FAQ)

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

A: No. While both parts share identical physical dimensions (5.00mm × 5.00mm), viewing angle (120°), color temperature (2700K), and CRI (80), the forward voltage and test current differ significantly. The MX-6S operates at 20V/60mA, while the MX-6 operates at 3.3V/300mA. Circuit redesign is mandatory, including power supply voltage adjustment and current-limiting circuit modification.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is based on: color and CCT (both 2700K warm white), CRI (both 80), viewing angle (both 120°), package type (both 2-SMD Gull Wing), physical footprint (both 5.00mm × 5.00mm), height (both 1.48mm max), thermal resistance (both 5°C/W), mounting type (both surface mount), and moisture sensitivity level (both 2A, 4 weeks). Electrical parameters (forward voltage, test current, maximum current) and product status differ and require circuit evaluation.

Q: Why is the MX-6 recommended over the MX-6S?

A: The MX-6 is an active product with RoHS compliance certification, ensuring long-term availability and regulatory compliance. The MX-6S is obsolete, making future procurement difficult. The MX-6 also offers superior efficiency (92 lm/W vs. 81 lm/W), reducing power dissipation.

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

A: The MX-6 features an exposed pad variant, which provides direct thermal contact to the PCB substrate. This improves heat dissipation in applications requiring higher power levels or thermal management. The MX-6S uses a standard 2-SMD Gull Wing package without exposed pad.

Q: Are there any compliance or regulatory differences between these parts?

A: The MX-6 is RoHS Compliant, while the MX-6S does not specify RoHS status. Both parts are REACH Unaffected. For applications requiring RoHS compliance certification, the MX-6 is the appropriate choice.

Q: What is the impact of the different lumens output (97 lm vs. 91 lm)?

A: The MX-6S delivers 97 lumens at 60mA test current, while the MX-6 delivers 91 lumens at 300mA test current. At equivalent light output levels, the MX-6 operates at higher efficiency (92 lm/W vs. 81 lm/W), resulting in lower power consumption and reduced thermal load on the component and PCB.

Q: Can the MX-6 be operated at the same current as the MX-6S (60mA)?

A: The MX-6 is rated for a maximum current of 1A and a test current of 300mA. Operating at 60mA is within the component's electrical limits; however, this would result in reduced light output and is not the specified operating point. Design calculations should be based on the 300mA test current specification for accurate performance prediction.
