Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-H1-0000-000FE3 is determined by the following critical parameters:

• Color and Correlated Color Temperature (CCT): Both parts must be White, Cool 5000K to maintain color consistency in the application.
• Viewing Angle: Both parts maintain 120° viewing angle, ensuring optical performance compatibility.
• Mounting Type and Package: Both parts are surface mount with 2-SMD, Gull Wing configuration and identical 5.00 mm × 5.00 mm footprint and 1.48 mm maximum seated height.
• Thermal Resistance: Both parts share 5°C/W thermal resistance, ensuring thermal management compatibility.
• Moisture Sensitivity Level: Both parts are rated 2A (4 Weeks), maintaining equivalent handling and storage requirements.
• REACH Compliance: Both parts are REACH Unaffected, ensuring regulatory alignment.

The MX6AWT-H1-0000-000DE3 qualifies as a substitute based on these parameters. However, differences in forward voltage (3.3V vs. 20V), test current (300mA vs. 60mA), and maximum current (1A vs. 175mA) indicate this is a functional equivalent from the same manufacturer family rather than a direct pin-for-pin replacement. Circuit redesign is required to accommodate the different electrical operating point.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-0000-000DE3 is the designated substitute for the obsolete MX6SWT-H1-0000-000FE3. Selection of this alternative is supported by:

• Product Status: The MX6AWT-H1-0000-000DE3 is Active, ensuring long-term availability and manufacturing support, whereas the MX6SWT-H1-0000-000FE3 is Obsolete.
• Regulatory Compliance: The MX6AWT-H1-0000-000DE3 carries RoHS Compliant certification, providing enhanced environmental compliance compared to the original part.
• Optical and Thermal Compatibility: Both parts maintain identical color temperature (5000K), CRI (80), viewing angle (120°), and thermal resistance (5°C/W), ensuring optical and thermal performance alignment.
• Mechanical Compatibility: Identical footprint (5.00 mm × 5.00 mm) and seated height (1.48 mm) allow direct PCB layout reuse with minor package variant accommodation (Exposed Pad addition).

Critical Design Consideration: The MX6AWT-H1-0000-000DE3 operates at 3.3V forward voltage with 300mA test current, compared to the MX6SWT-H1-0000-000FE3 at 20V and 60mA. Circuit redesign of the LED driver and power supply is mandatory to accommodate this electrical operating point change.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000DE3 be used as a direct drop-in replacement for the MX6SWT-H1-0000-000FE3?

A: No. While both parts share identical mechanical footprint, viewing angle, and color temperature, the forward voltage and test current differ significantly (3.3V/300mA vs. 20V/60mA). The LED driver circuit must be redesigned to operate at the lower voltage and higher current of the MX6AWT-H1-0000-000DE3.

Q: Are there any package differences between these parts?

A: Yes. The MX6SWT-H1-0000-000FE3 uses a standard 2-SMD Gull Wing package, while the MX6AWT-H1-0000-000DE3 includes an Exposed Pad variant. The Exposed Pad provides improved thermal dissipation. PCB layout must accommodate this additional pad for optimal thermal performance.

Q: What is the luminous flux difference between these parts?

A: At their respective test currents, the MX6SWT-H1-0000-000FE3 produces 126 lumens (60mA), while the MX6AWT-H1-0000-000DE3 produces 111 lumens (300mA). The MX6AWT-H1-0000-000DE3 achieves higher efficiency (112 lm/W vs. 105 lm/W), but absolute flux output is lower at its rated test current.

Q: Are both parts subject to the same moisture sensitivity requirements?

A: Yes. Both parts are rated MSL 2A (4 Weeks), requiring identical handling, storage, and reflow procedures.

Q: Does the MX6AWT-H1-0000-000DE3 provide better regulatory compliance?

A: Yes. The MX6AWT-H1-0000-000DE3 is RoHS Compliant, whereas RoHS status is not specified for the MX6SWT-H1-0000-000FE3. Both parts are REACH Unaffected.
