Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MX6SWT-A1-0000-000CF6 is determined by the following critical parameters:

Mechanical Compatibility: Package type (2-SMD, Gull Wing), footprint dimensions (5.00 mm × 5.00 mm), and maximum seated height (1.48 mm) must match or be compatible with PCB layout constraints.

Optical Compatibility: Color and correlated color temperature (CCT) must be identical (White, Warm, 3700K) to maintain consistent lighting characteristics in the application.

Electrical Compatibility: Forward voltage (Vf), test current, maximum current rating, and lumens output must fall within acceptable operating ranges for the circuit design. Thermal resistance (5°C/W) and CRI (80 Typ) provide baseline performance expectations.

Regulatory & Environmental: MSL rating (2A, 4 Weeks), REACH status (REACH Unaffected), and ECCN classification (EAR99) must be maintained for supply chain and compliance continuity.

Two substitute parts meet these criteria:

1. MX6SWT-A1-R250-000CE7 – Parametric equivalent within the same XLamp® MX-6S series; differs only in CCT (3000K vs. 3700K) and packaging format (Cut Tape & Digi-Reel® vs. standard packaging).

2. MX6AWT-A1-0000-000BF6 – Functional equivalent from the XLamp® MX-6 series; maintains identical optical and mechanical specifications but operates at significantly lower forward voltage (3.3V vs. 20V) and higher test current (300mA vs. 60mA), requiring circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

MX6SWT-A1-R250-000CE7 (Parametric Equivalent): This part is the closest substitute for direct replacement. It maintains identical electrical characteristics (20V Vf, 60mA test current, 87 lm/W), mechanical footprint, and thermal properties. The only difference is correlated color temperature (3000K vs. 3700K), which represents a warmer color shift. Both parts are classified as obsolete; however, MX6SWT-A1-R250-000CE7 has higher inventory availability (1182 pieces). Selection of this substitute requires acceptance of the CCT change and confirmation that the application tolerates the warmer color point.

MX6AWT-A1-0000-000BF6 (Functional Equivalent): This part is active in production status, providing long-term supply assurance. It maintains identical optical characteristics (3700K CCT, 120° viewing angle, 80 CRI) and mechanical compatibility (5.00 mm × 5.00 mm footprint, 1.48 mm height). However, it operates at significantly different electrical parameters: 3.3V forward voltage and 300mA test current versus 20V and 60mA. This substitution requires complete circuit redesign, including power supply modification, current limiting, and thermal management reassessment. The higher efficiency (98 lm/W vs. 87 lm/W) and active product status support long-term availability, but electrical redesign effort is substantial.

Frequently Asked Questions (FAQ)

Q: Can MX6SWT-A1-R250-000CE7 be used as a direct drop-in replacement for MX6SWT-A1-0000-000CF6?

A: Yes, with one consideration. Both parts share identical electrical specifications (20V Vf, 60mA test current, 87 lm/W), mechanical footprint (5.00 mm × 5.00 mm), and package type (2-SMD, Gull Wing). The only difference is correlated color temperature: MX6SWT-A1-R250-000CE7 operates at 3000K (warmer) versus 3700K (main part). If the application requires exact color matching at 3700K, this substitute is not suitable. If color temperature tolerance exists in the design specification, this part provides direct compatibility.

Q: What are the implications of substituting MX6AWT-A1-0000-000BF6?

A: MX6AWT-A1-0000-000BF6 maintains optical and mechanical compatibility but requires electrical circuit redesign. The forward voltage drops from 20V to 3.3V, and test current increases from 60mA to 300mA. Power supply voltage, current limiting resistors or active current sources, and thermal management must be recalculated. The benefit is active product status, ensuring long-term supply availability. This substitution is appropriate only when circuit redesign is feasible and the application can accommodate the higher current draw.

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

A: Yes. All three parts share identical mechanical specifications: 5.00 mm × 5.00 mm footprint, 1.48 mm maximum seated height, 2-SMD Gull Wing package type, and 5°C/W thermal resistance. MX6AWT-A1-0000-000BF6 includes an exposed pad, which provides enhanced thermal performance but does not affect footprint compatibility. PCB layout and reflow profile may require minor adjustment for the exposed pad variant, but footprint placement is identical.

Q: What is the impact of product status (Obsolete vs. Active) on part selection?

A: Both MX6SWT-A1-0000-000CF6 and MX6SWT-A1-R250-000CE7 are classified as obsolete, indicating discontinued production. Current inventory is available (708 and 1182 pieces respectively), but future supply is not guaranteed. MX6AWT-A1-0000-000BF6 is active in production, ensuring continued availability and supply chain stability for new designs or long-term production runs. For applications requiring extended production life, the active part is preferred despite electrical redesign requirements.

Q: Do all substitute parts meet the same regulatory and environmental standards?

A: Yes. All three parts maintain identical compliance status: REACH Unaffected, ECCN EAR99, MSL 2A (4 Weeks), and HTSUS 8541.41.0000. Regulatory and environmental requirements do not differentiate substitution eligibility.
