MX3SWT-A1-0000-000BB4 Equivalent & Substitute Parts

Part Overview

The MX3SWT-A1-0000-000BB4 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. Due to its obsolete status, equivalent parts from the active XLamp® product line are necessary to maintain supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MX3SWT-A1-0000-000BB4 is based on the following allowable parameters:

Mechanical Compatibility:

• Identical package type: 2-SMD, Gull Wing Exposed Pad
• Identical physical dimensions: 5.00 mm × 5.00 mm footprint
• Identical seated height: 1.48 mm maximum
• Identical thermal resistance: 11°C/W

Optical Compatibility:

• Color: White
• Viewing angle: 120°

Electrical Compatibility:

• Surface mount technology
• Moisture sensitivity level: 2A (4 Weeks)
• Regulatory compliance: REACH Unaffected

The substitute part MX3AWT-A1-0000-000CB1 meets all mechanical and optical compatibility criteria. However, this part operates at significantly different electrical parameters (3.7V forward voltage, 350 mA test current) compared to the original MX3SWT-A1-0000-000BB4 (10.7V forward voltage, 115 mA test current). Circuit redesign is required to accommodate these electrical differences.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000CB1 is the designated substitute for the obsolete MX3SWT-A1-0000-000BB4 based on identical mechanical and optical compatibility. Both parts share the same 2-SMD, Gull Wing Exposed Pad package, 5.00 mm × 5.00 mm footprint, 1.48 mm seated height, and 120° viewing angle.

The MX3AWT-A1-0000-000CB1 is classified as Active product status, ensuring ongoing availability and supply chain support. This part is RoHS Compliant and available in Tape & Reel (TR) packaging, providing advantages for automated assembly processes.

Critical consideration: The MX3AWT-A1-0000-000CB1 operates at 3.7V forward voltage and 350 mA test current, compared to the original part's 10.7V and 115 mA specifications. Direct pin-for-pin substitution is not possible without circuit modification. Power supply voltage, current-limiting resistor values, and thermal management must be re-evaluated for the substitute part's electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000CB1 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000BB4?

A: No. While both parts share identical mechanical dimensions, package type, and optical properties, the electrical parameters differ significantly. The substitute part requires 3.7V forward voltage versus 10.7V for the original part. Circuit redesign is mandatory.

Q: Are the physical footprints identical between these two parts?

A: Yes. Both parts use the 2-SMD, Gull Wing Exposed Pad package with 5.00 mm × 5.00 mm dimensions and 1.48 mm maximum seated height. PCB layout and assembly tooling remain compatible.

Q: What is the impact of the different forward voltage specifications?

A: The MX3AWT-A1-0000-000CB1 operates at approximately one-third the forward voltage of the original part. This requires redesign of the power supply circuit and current-limiting resistor network. Thermal management and power dissipation calculations must be recalculated.

Q: Are both parts suitable for automated assembly?

A: Yes. Both parts are surface mount components in 2-SMD, Gull Wing Exposed Pad packages. The MX3AWT-A1-0000-000CB1 is available in Tape & Reel (TR) packaging, which is standard for automated pick-and-place assembly.

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

A: The MX3AWT-A1-0000-000CB1 produces 104 lm at its test current (350 mA), compared to 97 lm for the original part at 115 mA. Both parts deliver approximately 79–80 lm/W efficiency.

Q: Are there any regulatory or compliance differences?

A: Both parts are REACH Unaffected. The MX3AWT-A1-0000-000CB1 is additionally RoHS Compliant, providing enhanced regulatory alignment for applications subject to RoHS requirements.
