MX3SWT-A1-0000-0008A9 Equivalent & Substitute Parts

Part Overview

The MX3SWT-A1-0000-0008A9 is a CreeLED XLamp® MX-3S warm white LED (2850K) in a 2-SMD surface mount package with exposed pad. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. The MX-3S series has been superseded by the MX-3 series, which maintains compatibility across key electrical and mechanical parameters while offering active product status.

Key Parameters

Substitute Part Grouping Explanation

The MX3AWT-A1-0000-0008A9 qualifies as a direct substitute based on the following alignment of critical parameters:

Matched Parameters:

• Color and correlated color temperature (2850K warm white)
• Luminous flux at 25°C (77 lm, identical range)
• Viewing angle (120°)
• Package configuration (2-SMD, Gull Wing Exposed Pad)
• Physical dimensions (5.00 mm × 5.00 mm)
• Seated height (1.48 mm)
• Thermal resistance (11°C/W)
• CRI rating (80 Typ)
• MSL classification (2A, 4 Weeks)

Electrical Differences: The MX3AWT operates at lower forward voltage (3.7V vs. 10.7V) and higher test current (350mA vs. 115mA), requiring circuit redesign for direct replacement. The MX3AWT-A1-0000-0008A9 is active product status, whereas the MX3SWT-A1-0000-0008A9 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-0008A9 is the designated substitute for the obsolete MX3SWT-A1-0000-0008A9. Selection of the MX3AWT is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• RoHS compliance certification, meeting current regulatory requirements
• Identical optical and thermal characteristics (flux, CRI, viewing angle, thermal resistance)
• Identical mechanical form factor and package configuration
• Identical MSL and REACH compliance status

Substitution requires electrical circuit redesign due to the significant difference in forward voltage (10.7V to 3.7V) and test current (115mA to 350mA). Power supply and current-limiting circuitry must be recalculated to accommodate the MX3AWT operating point.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-0008A9 be used as a direct pin-for-pin replacement?

A: Yes, the MX3AWT shares identical package configuration, pinout, and physical dimensions (5.00 mm × 5.00 mm, 2-SMD Gull Wing Exposed Pad). However, electrical circuit redesign is required due to different forward voltage and current specifications.

Q: What are the key differences between MX3SWT and MX3AWT?

A: The primary differences are forward voltage (10.7V vs. 3.7V), test current (115mA vs. 350mA), and product status (obsolete vs. active). Optical output (77 lm), color temperature (2850K), CRI (80), and viewing angle (120°) are identical.

Q: Is the MX3AWT RoHS compliant?

A: Yes, the MX3AWT-A1-0000-0008A9 is RoHS compliant. The original MX3SWT does not specify RoHS status.

Q: Are the thermal characteristics the same?

A: Yes, both parts have identical thermal resistance (11°C/W) and MSL rating (2A, 4 Weeks).

Q: What packaging options are available for the MX3AWT?

A: The MX3AWT-A1-0000-0008A9 is supplied in Tape & Reel (TR) packaging. The original MX3SWT packaging format is not specified in the provided data.
