Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000AE3 is based on the following criteria:

Compatible Parameters:

• Color and CCT (White, Cool 5000K) – must match exactly
• CRI (75 Typ) – maintained across series
• Viewing Angle (120°) – consistent optical performance
• Package Type (2-SMD, Gull Wing Exposed Pad) – mechanical compatibility
• Physical Dimensions (5.00mm × 5.00mm) – PCB footprint compatibility
• Height (1.48mm) – assembly clearance compatibility
• Thermal Resistance (11°C/W) – thermal management equivalence
• Moisture Sensitivity Level (2A) – handling and storage requirements

Allowable Variations:

• Forward Voltage (Vf): The MX-3 series operates at 3.7V versus the MX-3S at 10.7V. This represents a fundamental electrical difference requiring circuit redesign and is not a direct substitute without modification.
• Test Current: Varies between series (115mA vs. 350mA) due to voltage differences.
• Luminous Flux: Minor variations within acceptable performance range (91lm vs. 97lm).
• Lumens per Watt: Slight efficiency improvement (74 lm/W vs. 75 lm/W).
• Maximum Current: Differs due to series design (175mA vs. 500mA).

The MX3AWT-A1-0000-000BDZ is listed as a substitute based on optical and mechanical compatibility, though electrical parameters differ significantly.

Parameter Comparison

Engineering Selection Recommendations

For Direct Mechanical and Optical Substitution:

The MX3AWT-A1-0000-000BDZ maintains identical mechanical footprint, package configuration, and optical characteristics (color, CRI, viewing angle) as the MX3SWT-A1-0000-000AE3. Both parts are manufactured by CreeLED, Inc., and share the same 2-SMD gull wing exposed pad package with 5.00mm × 5.00mm dimensions and 1.48mm seated height.

Critical Electrical Consideration:

The MX3AWT-A1-0000-000BDZ operates at 3.7V typical forward voltage compared to 10.7V for the MX3SWT-A1-0000-000AE3. This represents a fundamental difference in the LED's internal structure and requires circuit redesign. Direct pin-for-pin substitution without electrical circuit modification is not possible.

Product Status and Compliance:

The MX3SWT-A1-0000-000AE3 is obsolete, while the MX3AWT-A1-0000-000BDZ is active with RoHS compliance certification. For new designs or production continuation, the MX3AWT-A1-0000-000BDZ is the recommended path forward from a supply chain and regulatory perspective.

Thermal and Handling:

Both parts share identical thermal resistance (11°C/W) and moisture sensitivity level (2A, 4 weeks), ensuring equivalent thermal management and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000BDZ be used as a direct drop-in replacement for the MX3SWT-A1-0000-000AE3?

A: No. While both parts share identical mechanical footprint and package configuration, the forward voltage differs significantly (3.7V vs. 10.7V). Direct substitution requires circuit redesign to accommodate the lower voltage requirement of the MX-3 series.

Q: What are the key mechanical compatibility factors?

A: Both parts use the same 2-SMD gull wing exposed pad package with 5.00mm × 5.00mm footprint and 1.48mm maximum seated height. PCB layout and assembly processes remain compatible.

Q: Are the optical characteristics equivalent?

A: Yes. Both parts deliver cool white light at 5000K with 75 CRI (typical) and 120° viewing angle. Luminous flux is similar (91lm vs. 97lm), with the MX3AWT-A1-0000-000BDZ providing slightly higher output.

Q: What is the impact of the voltage difference?

A: The MX3AWT-A1-0000-000BDZ requires a different current-limiting circuit design. The lower voltage (3.7V) and higher test current (350mA vs. 115mA) necessitate recalculation of series resistors or use of a dedicated LED driver circuit.

Q: Does the MX3AWT-A1-0000-000BDZ meet RoHS requirements?

A: Yes. The MX3AWT-A1-0000-000BDZ is RoHS compliant. RoHS status for the MX3SWT-A1-0000-000AE3 is not specified in the available data.

Q: Are thermal management requirements the same?

A: Yes. Both parts have identical thermal resistance of 11°C/W, so thermal design considerations remain unchanged.

Q: What are the moisture handling requirements?

A: Both parts are classified as Moisture Sensitivity Level 2A with a 4-week floor life. Storage and handling procedures are identical.
