Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-A1-0000-000CF5 is based on the following critical parameters that must align across parts:

Mandatory Matching Parameters:

• Color and CCT: White, Neutral 4250K
• Viewing Angle: 120°
• Mounting Type: Surface Mount (2-SMD configuration)
• Physical Footprint: 5.00 mm × 5.00 mm
• Height - Seated (Max): 1.48 mm
• Thermal Resistance: 5°C/W
• MSL Rating: 2A (4 Weeks)
• REACH Compliance: REACH Unaffected

Allowable Variation Parameters:

• Forward Voltage (Vf): May differ based on circuit design requirements
• Test Current: May differ; substitute must operate within specified current range
• Flux Output: Must remain within acceptable lumen range (100–107 lm at 25°C)
• Lumens/Watt Efficiency: May vary with different operating conditions
• CRI: Must maintain 80 (Typ) or higher
• Product Status: Active status preferred for new designs

The MX6AWT-A1-0000-000CZ5 qualifies as a substitute based on matching all mandatory parameters while offering active product status and improved electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-A1-0000-000CZ5 is the qualified substitute for the obsolete MX6SWT-A1-0000-000CF5. Selection is based on the following engineering criteria:

Product Status: The substitute part maintains active product status, ensuring long-term availability and supply chain continuity. The main part is classified as obsolete, making substitution necessary for production continuity.

Compliance & Certifications: Both parts maintain REACH Unaffected status. The substitute part carries RoHS Compliant certification, providing additional environmental compliance assurance for new designs.

Electrical & Optical Compatibility: Both parts deliver identical flux output (104 lm) and maintain the same CRI rating (80 Typ) at the specified color temperature (4250K neutral white). The substitute exhibits improved lumens/watt efficiency (105 lm/W vs. 87 lm/W), indicating enhanced performance characteristics.

Physical & Thermal Compatibility: Identical footprint (5.00 mm × 5.00 mm), height (1.48 mm max), and thermal resistance (5°C/W) ensure direct PCB layout compatibility. The exposed pad design in the substitute part provides improved thermal management.

Circuit Design Consideration: The substitute part operates at 3.3V typical forward voltage with 300 mA test current, compared to the main part's 20V and 60 mA. Circuit redesign is required to accommodate this voltage and current difference. The substitute's maximum current rating of 1 A provides greater operational headroom compared to the main part's 175 mA maximum.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000CZ5 be used as a direct drop-in replacement for the MX6SWT-A1-0000-000CF5?

A: Physical and thermal compatibility is direct; however, circuit redesign is required. The substitute part operates at 3.3V typical forward voltage versus the main part's 20V. Current-limiting resistor values and power supply specifications must be recalculated for the 300 mA test current and 1 A maximum current rating of the substitute.

Q: What are the key parameters that define substitution eligibility?

A: Substitution is determined by matching color/CCT (4250K neutral white), viewing angle (120°), mounting type (surface mount 2-SMD), physical footprint (5.00 mm × 5.00 mm), seated height (1.48 mm max), thermal resistance (5°C/W), MSL rating (2A, 4 Weeks), and REACH compliance status. Flux output must remain within the 100–107 lm range at 25°C.

Q: Does the exposed pad design of the substitute part affect PCB layout?

A: The exposed pad in the MX6AWT-A1-0000-000CZ5 provides enhanced thermal dissipation. PCB layout should include thermal vias connected to the exposed pad for optimal heat transfer. Standard gull wing footprints remain compatible; thermal pad connection is optional but recommended for high-current applications.

Q: Are there compliance differences between the main part and substitute?

A: The substitute part carries RoHS Compliant certification, whereas the main part does not specify RoHS status. Both parts maintain REACH Unaffected status. For applications requiring RoHS compliance, the substitute part provides explicit certification.

Q: What is the impact of the substitute part's higher lumens/watt efficiency?

A: The substitute delivers 105 lm/W versus the main part's 87 lm/W at their respective test currents. This indicates improved energy efficiency. However, direct lumen-for-lumen comparison requires accounting for the different test current conditions (300 mA vs. 60 mA). Both parts deliver 104 lm flux output at 25°C within the specified range.

Q: Is the substitute part suitable for existing inventory of the obsolete part?

A: The substitute is suitable for new production and design revisions. Existing inventory of the MX6SWT-A1-0000-000CF5 should be consumed according to existing circuit specifications. Transition to the substitute part should occur during planned design updates to accommodate the voltage and current differences.
