Key Parameters

Substitute Part Grouping Explanation

The MX6AWT-H1-R250-000BZ6 qualifies as a functional substitute based on the following alignment of critical parameters:

Matching Parameters:

• Color and CCT: Both White, Warm 3500K
• Flux output: Both 97 lm (94–100 lm range) at 25°C
• CRI: Both 80
• Viewing angle: Both 120°
• Package type: Both 2-SMD, Gull Wing configuration
• Physical dimensions: Both 5.00mm × 5.00mm
• Height (seated): Both 1.48mm maximum
• Thermal resistance: Both 5°C/W
• Moisture sensitivity: Both 2A (4 Weeks)

Differing Parameters:

• Forward voltage: MX6SWT operates at 20V; MX6AWT operates at 3.3V
• Test current: MX6SWT at 60mA; MX6AWT at 300mA
• Maximum current: MX6SWT 175mA; MX6AWT 1A
• Efficiency: MX6SWT 81 lm/W; MX6AWT 98 lm/W
• Product status: MX6SWT is Obsolete; MX6AWT is Active
• Package detail: MX6SWT has standard gull wing; MX6AWT has gull wing with exposed pad

The substitute is suitable where the application can accommodate the lower forward voltage (3.3V vs. 20V) and higher current requirements of the MX6AWT series.

Parameter Comparison

Engineering Selection Recommendations

MX6AWT-H1-R250-000BZ6 as Primary Substitute:

The MX6AWT-H1-R250-000BZ6 is the recommended substitute for the obsolete MX6SWT-H1-R250-000BZ6. Both parts maintain identical photometric output (97 lm at 3500K with CRI 80), identical viewing angle (120°), and identical physical footprint (5.00mm × 5.00mm, 1.48mm height). Both carry equivalent regulatory compliance (REACH Unaffected, EAR99 classification, HTSUS 8541.41.0000).

The MX6AWT operates at Active product status, ensuring long-term availability and supply chain continuity. The exposed pad design of the MX6AWT provides improved thermal management compared to the standard gull wing configuration.

Critical Design Consideration:

The primary design change required is electrical: the MX6AWT operates at 3.3V forward voltage with 300mA test current, compared to the MX6SWT's 20V at 60mA. Applications must be redesigned to accommodate this lower voltage and higher current requirement. The MX6AWT achieves superior efficiency (98 lm/W vs. 81 lm/W), resulting in lower power dissipation at equivalent light output.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-R250-000BZ6 be used as a direct drop-in replacement for the MX6SWT-H1-R250-000BZ6?

A: No. While both parts deliver identical light output (97 lm) at the same color temperature (3500K) and CRI (80), the forward voltage differs significantly (3.3V vs. 20V). The power supply and current-limiting circuitry must be redesigned. The MX6AWT requires a 3.3V supply with 300mA capability at test current, whereas the MX6SWT required 20V at 60mA. Physical footprint and height are identical, allowing PCB layout to remain unchanged.

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

A: Substitution eligibility is determined by: color and correlated color temperature (CCT), luminous flux output, color rendering index (CRI), viewing angle, package type, physical dimensions, and thermal characteristics. The MX6AWT matches all these parameters with the MX6SWT. Electrical parameters (forward voltage and current) differ and require circuit redesign but do not prevent functional substitution.

Q: Does the exposed pad on the MX6AWT affect PCB layout?

A: The exposed pad on the MX6AWT provides direct thermal contact to the PCB, improving heat dissipation. PCB layout should include a thermal pad connected to ground or a heat sink plane. Standard gull wing layouts without exposed pad provisions can be modified to accommodate the exposed pad without affecting component placement or electrical routing.

Q: Are both parts compliant with the same regulatory standards?

A: Yes. Both the MX6SWT-H1-R250-000BZ6 and MX6AWT-H1-R250-000BZ6 carry identical regulatory status: REACH Unaffected, ECCN EAR99, and HTSUS classification 8541.41.0000. Both maintain MSL 2A (4 Weeks) moisture sensitivity level.

Q: Why is the MX6AWT more efficient (98 lm/W vs. 81 lm/W) while delivering the same light output?

A: The MX6AWT operates at lower forward voltage (3.3V) and higher current (300mA test) compared to the MX6SWT (20V, 60mA test). At identical luminous flux (97 lm), the MX6AWT dissipates less total power, resulting in higher lumens-per-watt efficiency. This reflects improvements in the XLamp® MX-6 generation compared to the MX-6S.
