MX6SWT-A1-0000-000CE6 Equivalent & Substitute Parts

Part Overview

The MX6SWT-A1-0000-000CE6 is a CreeLED XLamp® MX-6S warm white LED (3500K) in a 2-SMD, Gull Wing surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The part delivers 104 lumens at 25°C under 60mA test current with a forward voltage of 20V and 87 lm/W efficiency. Its 120° viewing angle and compact 5.00mm × 5.00mm footprint make it suitable for general illumination applications requiring warm white color temperature.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MX6SWT-A1-0000-000CE6 is determined by the following critical parameters:

Mechanical Compatibility: Package type (2-SMD, Gull Wing), footprint dimensions (5.00 mm × 5.00 mm), and seated height (1.48 mm maximum) must remain identical to ensure PCB layout compatibility without redesign.

Optical Compatibility: Color temperature (warm white in the 3000K–3500K range) and viewing angle (120°) define the optical performance envelope. CRI of 80 (Typ) establishes the color rendering baseline.

Electrical Compatibility: Forward voltage and test current define the LED's operating point. Substitutes must operate within the same voltage class to maintain circuit compatibility without significant redesign of current-limiting networks.

Thermal & Reliability: Thermal resistance (5°C/W) and moisture sensitivity level (2A, 4 Weeks) establish thermal and handling requirements.

Regulatory & Supply Status: REACH compliance and product status (Active vs. Obsolete) influence long-term availability and regulatory suitability.

The two substitute parts identified below meet these criteria with specific trade-offs noted in the parameter comparison.

Parameter Comparison

Engineering Selection Recommendations

MX6SWT-A1-R250-000CE7 (Parametric Equivalent): This part maintains identical electrical characteristics (20V Vf, 60 mA test current, 87 lm/W) and mechanical form factor as the main part. The primary difference is color temperature (3000K vs. 3500K), which represents a warmer tone. Both parts are obsolete, so this substitution does not improve long-term supply security. Selection is appropriate when color temperature shift to 3000K is acceptable within application tolerances and when Cut Tape or Digi-Reel® packaging meets procurement requirements.

MX6AWT-A1-0000-000BE6 (Functional Substitute): This part is from the active XLamp® MX-6 series and maintains the same color temperature (3500K), viewing angle (120°), and mechanical footprint. However, it operates at significantly lower voltage (3.3V vs. 20V) and higher current (300 mA test vs. 60 mA), requiring complete redesign of the current-limiting circuit. The higher efficiency (98 lm/W vs. 87 lm/W) and active product status provide long-term supply security. This substitution is suitable only when circuit redesign is feasible and the lower voltage operation aligns with system architecture. The exposed pad variant may improve thermal performance in high-power applications.

Regulatory Compliance: All three parts carry REACH Unaffected status. The MX6AWT-A1-0000-000BE6 is explicitly RoHS Compliant, while RoHS status is not specified for the MX-6S variants. For applications requiring RoHS certification, the MX6AWT-A1-0000-000BE6 is the preferred choice.

Frequently Asked Questions (FAQ)

Q: Can I directly replace MX6SWT-A1-0000-000CE6 with MX6AWT-A1-0000-000BE6 without circuit changes?

A: No. The MX6AWT operates at 3.3V with 300 mA test current, compared to 20V and 60 mA for the MX6SWT. The forward voltage difference requires redesign of the current-limiting resistor or driver circuit. Direct substitution without circuit modification will result in overcurrent and component failure.

Q: What is the difference between the two MX-6S variants (MX6SWT-A1-0000-000CE6 and MX6SWT-A1-R250-000CE7)?

A: Both are electrically and mechanically identical (20V, 60 mA, 104 lm, 87 lm/W). The primary difference is color temperature: 3500K (main part) vs. 3000K (substitute). The packaging format also differs: bulk vs. Cut Tape/Digi-Reel®. Selection depends on whether the warmer 3000K tone is acceptable and packaging format availability.

Q: Why is the MX6AWT-A1-0000-000BE6 listed as a substitute if it requires circuit redesign?

A: The MX6AWT is a functional substitute in terms of optical performance (color, CRI, viewing angle) and mechanical compatibility (footprint, height). It is the only active product among the three parts, providing long-term supply security. However, its low voltage operation necessitates circuit redesign. This substitution is appropriate for new designs or redesign projects, not for direct drop-in replacement.

Q: Are all three parts compatible with the same PCB layout?

A: Yes, mechanically. All three parts share identical footprint dimensions (5.00 mm × 5.00 mm), seated height (1.48 mm), and 2-SMD Gull Wing package type. However, the MX6AWT-A1-0000-000BE6 features an exposed pad variant, which may require PCB layout adjustment for thermal management. Electrical circuit compatibility depends on voltage and current requirements, not PCB layout alone.

Q: What is the impact of the exposed pad on the MX6AWT-A1-0000-000BE6?

A: The exposed pad provides an additional thermal path to the PCB, improving heat dissipation. This is beneficial in high-power or thermally constrained applications. PCB layout must include a thermal via pattern connected to the exposed pad to realize this benefit. The mechanical footprint remains compatible with standard 5.00 mm × 5.00 mm layouts.

Q: Which part should I select for a new design?

A: The MX6AWT-A1-0000-000BE6 is the recommended choice for new designs due to its active product status, RoHS compliance, and higher efficiency (98 lm/W). The circuit must be designed for 3.3V operation and 300 mA test current. If 20V operation is a system requirement, the MX6SWT-A1-R250-000CE7 provides parametric equivalence, though both MX-6S variants are obsolete and may face future supply constraints.

Q: Are there any thermal or reliability differences between these parts?

A: All three parts share identical thermal resistance (5°C/W) and moisture sensitivity level (2A, 4 Weeks). Thermal performance in application depends on PCB layout, thermal vias, and ambient conditions, not the parts themselves. The exposed pad on the MX6AWT-A1-0000-000BE6 enables improved thermal management if properly implemented in PCB design.
