Key Parameters

Substitute Part Grouping Explanation

The MX3AWT-A1-0000-000BE7 qualifies as a functional substitute based on the following alignment of critical parameters:

Matching Parameters:

• Color temperature: 3000K warm white (identical)
• CRI: 80 (identical)
• Viewing angle: 120° (identical)
• Package type: 2-SMD, Gull Wing Exposed Pad (identical)
• Physical dimensions: 5.00mm × 5.00mm (identical)
• Height: 1.48mm (identical)
• Thermal resistance: 11°C/W (identical)
• Mounting type: Surface Mount (identical)

Differing Parameters: The substitute operates at lower forward voltage (3.7V vs. 10.7V) and higher test current (350mA vs. 115mA), resulting in different power delivery characteristics. The substitute delivers 97 lumens at its test current, representing a marginal flux increase. The substitute part is active in production status, whereas the main part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000BE7 is available as an active production part with RoHS compliance certification, addressing the obsolescence status of the MX3SWT-A1-0000-000AE7. Both parts share identical mechanical packaging, thermal characteristics, and optical properties (color temperature, CRI, viewing angle).

Circuit design modifications are required due to the significant difference in forward voltage (10.7V to 3.7V) and test current (115mA to 350mA). The substitute part operates at lower voltage and higher current, necessitating recalculation of current-limiting resistor values and power supply specifications. The substitute delivers marginally higher luminous flux (97 lm vs. 91 lm) at comparable efficiency (75 lm/W vs. 74 lm/W).

Selection of the substitute part is appropriate for applications requiring warm white 3000K illumination with 120° beam angle in surface mount form factor, provided that the electrical operating point can be accommodated within the design constraints.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000BE7 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000AE7?

A: No. While both parts share identical package geometry, thermal resistance, and optical characteristics, the forward voltage and current specifications differ significantly. The substitute operates at 3.7V and 350mA versus 10.7V and 115mA for the main part. Circuit redesign is required, including modification of current-limiting resistors and power supply voltage selection.

Q: Are the physical dimensions and mounting footprints identical?

A: Yes. Both parts are 5.00mm × 5.00mm with 1.48mm maximum seated height, using 2-SMD Gull Wing Exposed Pad packaging. PCB footprints and assembly processes remain unchanged.

Q: What is the difference between the XLamp® MX-3S and XLamp® MX-3 series?

A: The MX-3S operates at higher forward voltage (10.7V) with lower current (115mA), while the MX-3 operates at lower forward voltage (3.7V) with higher current (350mA). Both deliver comparable luminous efficacy and are available in warm white 3000K with 80 CRI.

Q: Is the substitute part RoHS compliant?

A: Yes. The MX3AWT-A1-0000-000BE7 carries RoHS compliance certification. RoHS status for the main part is not specified in available documentation.

Q: What is the moisture sensitivity level for both parts?

A: Both parts are rated MSL 2A with a 4-week floor life rating, requiring identical moisture control and storage procedures.
