Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000ADZ is evaluated based on the following critical parameters:

Matching Parameters (Required for Direct Substitution):

• Color and CCT: White, Cool 5000K
• Flux output range: 91 lm nominal (87–94 lm acceptable)
• CRI: 75 (Typ)
• Viewing angle: 120°
• Package type: 2-SMD, Gull Wing Exposed Pad
• Physical dimensions: 5.00 mm × 5.00 mm footprint
• Height: 1.48 mm maximum
• Thermal resistance: 11°C/W
• MSL rating: 2A (4 Weeks)

Allowable Variations (Circuit-Dependent):

• Forward voltage (Vf): Acceptable within design margin if circuit topology accommodates
• Test current and maximum current: Acceptable if power supply and thermal management support the operating point
• Lumens/Watt efficiency: Acceptable if system power budget permits

The MX3AWT-A1-0000-000ADZ qualifies as a substitute based on matching optical, thermal, and mechanical specifications. However, the forward voltage and current characteristics differ significantly and must be evaluated against circuit design constraints.

Parameter Comparison

Engineering Selection Recommendations

MX3AWT-A1-0000-000ADZ as Substitute:

The MX3AWT-A1-0000-000ADZ is an active product from CreeLED, Inc., providing continuity for the obsolete MX3SWT-A1-0000-000ADZ. Both components share identical optical output (91 lm at 5000K), color rendering index (75), viewing angle (120°), and mechanical form factor (5.00 mm × 5.00 mm, 2-SMD package).

Critical Design Consideration:

The MX3AWT operates at 3.7V forward voltage versus 10.7V for the MX3SWT, with correspondingly higher test current (350 mA vs. 115 mA). Circuit redesign is required to accommodate this voltage and current shift. Power dissipation at test current is approximately 1.30W (MX3AWT) compared to 1.23W (MX3SWT), requiring thermal management evaluation.

Compliance Advantage:

The MX3AWT-A1-0000-000ADZ carries RoHS Compliant certification, whereas the MX3SWT status is not specified. Both components maintain REACH Unaffected status and identical MSL ratings (2A, 4 Weeks).

Availability:

The MX3AWT-A1-0000-000ADZ is currently in active production with confirmed inventory (717 Pcs), ensuring long-term supply continuity compared to the obsolete MX3SWT series.

Frequently Asked Questions (FAQ)

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

A: No. While both components share identical optical output, color temperature, CRI, viewing angle, and mechanical footprint, the forward voltage differs significantly (3.7V vs. 10.7V). Circuit redesign is required to accommodate the lower voltage and higher current operating point of the MX3AWT.

Q: What are the key parameters that must match for substitution?

A: Color and CCT (5000K), luminous flux (91 lm nominal), CRI (75), viewing angle (120°), package type (2-SMD Gull Wing), footprint (5.00 mm × 5.00 mm), and height (1.48 mm maximum). Forward voltage and current are circuit-dependent and may vary if the power supply and thermal design accommodate the operating point.

Q: Is the MX3AWT-A1-0000-000ADZ RoHS compliant?

A: Yes. The MX3AWT-A1-0000-000ADZ is RoHS Compliant. The MX3SWT RoHS status is not specified in available documentation.

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

A: Both the MX3SWT-A1-0000-000ADZ and MX3AWT-A1-0000-000ADZ carry MSL rating 2A (4 Weeks), indicating identical moisture handling and storage requirements.

Q: Are there any thermal management differences between these components?

A: Both components have identical thermal resistance (11°C/W). However, the MX3AWT operates at higher current (350 mA vs. 115 mA at test conditions), resulting in approximately 7% higher power dissipation. Thermal design must account for this increased heat generation.

Q: What is the product status difference, and why does it matter?

A: The MX3SWT-A1-0000-000ADZ is obsolete, indicating end-of-life status and no further production. The MX3AWT-A1-0000-000ADZ is active, ensuring ongoing availability, support, and supply chain continuity for new designs and production runs.
