MX3SWT-A1-0000-000BF7 Equivalent & Substitute Parts

Part Overview

The MX3SWT-A1-0000-000BF7 is a CreeLED XLamp® MX-3S warm white LED (3200K) in a 2-SMD surface mount package with exposed pad. This part is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. The MX-3S series has been superseded by newer XLamp® generations, requiring careful parameter matching for functional replacement.

Key Parameters

Substitute Part Grouping Explanation

The MX6AWT-A1-0000-000BF7 qualifies as a functional substitute based on the following matching parameters:

• Color Temperature: Both parts emit warm white light at 3200K
• Luminous Flux: Both deliver 97lm (94–100lm range) at their respective test currents
• Color Rendering Index: Both maintain CRI of 80 (Typical)
• Viewing Angle: Both provide 120° viewing angle
• Package Footprint: Both use 2-SMD, Gull Wing Exposed Pad in 5.00mm × 5.00mm form factor
• Maximum Height: Both are 1.48mm maximum seated height
• Moisture Sensitivity: Both rated MSL 2A (4 Weeks)

Critical Differences Requiring Circuit Redesign:

• Forward Voltage: MX6AWT operates at 3.3V (vs. 10.7V for MX3SWT)
• Test Current: MX6AWT requires 300mA (vs. 115mA for MX3SWT)
• Thermal Resistance: MX6AWT has 5°C/W (vs. 11°C/W for MX3SWT)

These electrical differences necessitate power supply and current-limiting circuit modifications.

Parameter Comparison

Engineering Selection Recommendations

For Obsolescence Mitigation: The MX6AWT-A1-0000-000BF7 is the designated substitute for the obsolete MX3SWT-A1-0000-000BF7. The MX6AWT carries Active product status and maintains RoHS Compliance, ensuring long-term availability and regulatory alignment.

For Direct Replacement Without Circuit Modification: Direct pin-for-pin substitution is not possible due to the 10.7V to 3.3V forward voltage difference and the 115mA to 300mA current requirement change. Power supply voltage and current-limiting resistor or driver circuit must be redesigned.

For Thermal Performance: The MX6AWT provides superior thermal characteristics (5°C/W vs. 11°C/W), reducing junction temperature rise and improving long-term reliability in thermally constrained applications.

Compliance Considerations: Both parts maintain identical REACH and ECCN classifications (EAR99), with no additional regulatory burden for substitution.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000BF7 be used as a drop-in replacement for the MX3SWT-A1-0000-000BF7?

A: No. While both parts share identical color temperature (3200K), luminous flux (97lm), CRI (80), viewing angle (120°), and physical footprint (5.00mm × 5.00mm), the forward voltage differs significantly (3.3V vs. 10.7V) and test current requirements differ (300mA vs. 115mA). Circuit redesign is required.

Q: What circuit modifications are necessary for substitution?

A: The power supply voltage must be reduced from 10.7V to 3.3V operation, and the current-limiting circuit must be adjusted to accommodate 300mA instead of 115mA. Consult the respective datasheets for detailed electrical specifications and application schematics.

Q: Are the packages mechanically compatible?

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

Q: Does the MX6AWT offer any performance advantages?

A: The MX6AWT provides higher luminous efficacy (98 lm/W vs. 79 lm/W) and superior thermal resistance (5°C/W vs. 11°C/W), resulting in lower junction temperatures and improved long-term reliability.

Q: Are there any regulatory or compliance differences?

A: No. Both parts maintain identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS codes (8541.41.0000). The MX6AWT additionally carries RoHS Compliance certification.

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

A: Both parts are rated MSL 2A (4 Weeks), requiring identical moisture control and storage protocols during manufacturing and assembly.
