Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000AF8 is based on the following criteria derived from the provided parameters:

Mandatory Compatibility Parameters:

• Color and CCT: White, Warm 2900K (exact match required)
• CRI: 80 (Typ) or equivalent
• Viewing Angle: 120° (exact match)
• Package / Case: 2-SMD, Gull Wing Exposed Pad (exact match)
• Size / Dimension: 5.00mm × 5.00mm (exact match)
• Height (Seated, Max): 1.48mm (exact match)
• Mounting Type: Surface Mount

Electrical Parameters Allowing Substitution:

• Forward Voltage (Vf): May differ; circuit design must accommodate
• Test Current: May differ; circuit design must accommodate
• Maximum Current: May differ; circuit design must accommodate
• Lumens/Watt: May differ; performance optimization acceptable
• Thermal Resistance: May differ; thermal design must accommodate

The identified substitute MX6AWT-A1-0000-000AF8 meets all mandatory compatibility parameters while differing in electrical characteristics that require circuit-level evaluation.

Engineering Selection Recommendations

MX6AWT-A1-0000-000AF8 as Primary Substitute:

The MX6AWT-A1-0000-000AF8 is the identified substitute for the obsolete MX3SWT-A1-0000-000AF8. Both parts share identical color temperature (2900K), CRI (80 Typ), viewing angle (120°), package configuration (2-SMD Gull Wing Exposed Pad), physical dimensions (5.00mm × 5.00mm), and seated height (1.48mm).

The MX6AWT-A1-0000-000AF8 is classified as Active product status, ensuring ongoing availability and supply chain continuity. Both parts carry identical regulatory compliance: REACH Unaffected and ECCN EAR99 classification.

Critical Electrical Differences Requiring Circuit Redesign:

The MX6AWT-A1-0000-000AF8 operates at 3.3V typical forward voltage with 300mA test current, compared to the MX3SWT-A1-0000-000AF8 at 10.7V typical with 115mA test current. This represents a fundamental shift in power delivery architecture. The substitute part delivers improved efficiency (92 lm/W versus 74 lm/W) and lower thermal resistance (5°C/W versus 11°C/W), but requires complete driver circuit redesign to accommodate the lower voltage and higher current requirements.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000AF8 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000AF8?

A: No. While both parts are mechanically and optically compatible (identical package, dimensions, color, CRI, and viewing angle), the electrical characteristics differ significantly. The MX6AWT-A1-0000-000AF8 requires 3.3V at 300mA versus 10.7V at 115mA for the MX3SWT-A1-0000-000AF8. Driver circuit redesign is mandatory.

Q: Are the physical packages identical?

A: Yes. Both parts use 2-SMD Gull Wing Exposed Pad configuration with 5.00mm × 5.00mm footprint and 1.48mm maximum seated height. PCB layout and reflow profiles remain compatible.

Q: What is the impact of the lower forward voltage on system design?

A: The MX6AWT-A1-0000-000AF8 operates at 3.3V versus 10.7V, requiring a different power supply architecture or buck converter topology. Current handling increases from 115mA to 300mA at test conditions, necessitating revised current limiting and thermal management calculations.

Q: Do both parts have identical color and light output characteristics?

A: Yes. Both parts deliver 91 lm (87–94 lm range) at their respective test currents with 2900K warm white color temperature and 80 CRI. Optical performance is equivalent.

Q: What are the regulatory and compliance implications?

A: Both parts carry identical regulatory status: REACH Unaffected and ECCN EAR99. Moisture sensitivity level is 2A (4 Weeks) for both. No compliance barriers exist for substitution.

Q: How does thermal performance differ?

A: The MX6AWT-A1-0000-000AF8 has superior thermal performance with 5°C/W thermal resistance compared to 11°C/W for the MX3SWT-A1-0000-000AF8. This improvement reduces junction temperature rise and extends operational life under identical ambient conditions.
