MX3SWT-A1-0000-000BB1 Equivalent & Substitute Parts

Part Overview

The MX3SWT-A1-0000-000BB1 is an XLamp® MX-3S white LED in a 2-SMD, Gull Wing Exposed Pad package designed for surface mount applications. This part is classified as Obsolete, making identification of suitable substitute components essential for ongoing production and design requirements. The XLamp® MX-3S series delivers 97 lm at 115 mA forward current with a forward voltage of 10.7V and a 120° viewing angle. Substitution becomes necessary when original inventory is depleted or when transitioning to active product lines.

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000BB1 is based on the following allowable parameters:

• Color: White (must match)
• Mounting Type: Surface Mount (must match)
• Package / Case: 2-SMD, Gull Wing Exposed Pad (must match)
• Size / Dimension: 0.197" L × 0.197" W (5.00 mm × 5.00 mm) (must match)
• Height - Seated (Max): 0.058" (1.48 mm) (must match)
• Thermal Resistance of Package: 11°C/W (must match)
• Viewing Angle: 120° (must match)
• Moisture Sensitivity Level (MSL): 2A (4 Weeks) (must match)
• REACH Status: REACH Unaffected (must match)
• ECCN: EAR99 (must match)

The MX3AWT-A1-0000-000CB1 qualifies as a substitute because it maintains identical mechanical, thermal, and regulatory parameters. Electrical characteristics (forward voltage, test current, and flux output) differ due to the transition from the MX-3S to the active MX-3 series, but the physical and environmental specifications remain compatible for PCB integration.

Engineering Selection Recommendations

The MX3AWT-A1-0000-000CB1 is the designated substitute for the obsolete MX3SWT-A1-0000-000BB1. Selection is supported by the following factors:

• Product Status: The MX3AWT-A1-0000-000CB1 is Active, ensuring continued availability and supply chain stability compared to the Obsolete status of the main part.
• Compliance: Both parts maintain REACH Unaffected and EAR99 ECCN classifications. The substitute adds RoHS Compliance certification, meeting modern regulatory requirements.
• Physical Compatibility: Identical package geometry, thermal resistance, and moisture sensitivity ensure direct PCB footprint compatibility without layout modifications.
• Electrical Performance: While forward voltage and test current differ between the MX-3S and MX-3 series, lumens per watt efficiency remains comparable (79 lm/W vs. 80 lm/W). Circuit design must account for the reduced forward voltage (3.7V vs. 10.7V) and increased test current (350 mA vs. 115 mA) of the substitute.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000CB1 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000BB1?

A: The MX3AWT-A1-0000-000CB1 is mechanically and thermally compatible for PCB integration. However, the significant difference in forward voltage (3.7V vs. 10.7V) and test current (350 mA vs. 115 mA) requires circuit redesign. The power supply and current-limiting circuitry must be adjusted to accommodate the substitute's electrical characteristics.

Q: Are there any package or mounting differences between these parts?

A: No. Both parts use identical 2-SMD, Gull Wing Exposed Pad packaging with 5.00 mm × 5.00 mm footprints and 1.48 mm maximum seated height. PCB layout and reflow profiles remain unchanged.

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

A: The MX3AWT-A1-0000-000CB1 operates at 3.7V typical forward voltage compared to 10.7V for the MX3SWT-A1-0000-000BB1. This requires a different power supply configuration and current-limiting resistor or driver circuit. The substitute's lower voltage may reduce power dissipation in series resistor networks but demands higher current delivery from the power source.

Q: Does the substitute meet current regulatory and compliance standards?

A: Yes. The MX3AWT-A1-0000-000CB1 is RoHS Compliant and maintains REACH Unaffected status, meeting modern environmental and regulatory requirements. The main part does not specify RoHS compliance.

Q: What is the difference in luminous flux between the two parts?

A: The MX3AWT-A1-0000-000CB1 produces 104 lm at its test current (350 mA) compared to 97 lm for the MX3SWT-A1-0000-000BB1 at 115 mA. Direct flux comparison requires normalization to equivalent operating conditions, as the parts operate at different currents.

Q: Is the substitute available in the same packaging format?

A: The substitute is supplied in Tape & Reel (TR) format, while the main part packaging is not specified. Tape & Reel packaging is standard for high-volume surface mount assembly and is compatible with automated pick-and-place equipment.
