Key Parameters

Substitute Part Grouping Explanation

Substitution for the MX6SWT-A1-R250-000FDZ is determined by the following critical parameters:

Parametric Equivalent (Same Electrical & Mechanical Characteristics):

• Color and CCT: White, Cool 5000K
• Voltage - Forward (Vf): 20V
• Current - Test: 60mA
• Flux @ 25°C: 126lm (122lm ~ 130lm)
• Viewing Angle: 120°
• Package / Case: 2-SMD, Gull Wing
• Physical dimensions: 5.00mm x 5.00mm
• Thermal Resistance: 5°C/W

The parametric equivalent MX6SWT-A1-R250-000FE3 matches all electrical and mechanical specifications. The only difference is packaging format (Cut Tape & Digi-Reel® versus standard packaging).

Similar Substitute (Different Electrical Characteristics):

• Color and CCT: White, Cool 5000K (matched)
• Viewing Angle: 120° (matched)
• Package / Case: 2-SMD, Gull Wing Exposed Pad (mechanically compatible)
• Physical dimensions: 5.00mm x 5.00mm (matched)
• Thermal Resistance: 5°C/W (matched)

The MX6AWT-A1-R250-000DDZ operates at significantly different electrical parameters (3.3V Vf, 300mA test current) and belongs to the XLamp® MX-6 series rather than MX-6S. This part is suitable only when circuit design accommodates the different voltage and current requirements.

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalent): Select MX6SWT-A1-R250-000FE3 when the original MX6SWT-A1-R250-000FDZ is unavailable. This part maintains identical electrical performance (20V Vf, 60mA test current, 126lm output) and mechanical compatibility. The difference in packaging format (Cut Tape & Digi-Reel® versus standard packaging) does not affect circuit performance. Both parts share obsolete product status.

For Circuit Redesign (Similar Substitute): The MX6AWT-A1-R250-000DDZ is suitable only when circuit design is modified to accommodate different electrical parameters. This part operates at 3.3V forward voltage and 300mA test current, requiring corresponding changes to current-limiting resistors and power supply design. The MX6AWT-A1-R250-000DDZ offers active product status and RoHS compliance, providing longer-term availability. Flux output is lower (111lm versus 126lm), and efficiency is higher (112 lm/W versus 105 lm/W). All three parts share identical mechanical dimensions, thermal resistance, viewing angle, and MSL rating.

Frequently Asked Questions (FAQ)

Q: Can MX6SWT-A1-R250-000FE3 be used as a direct drop-in replacement for MX6SWT-A1-R250-000FDZ?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (20V Vf, 60mA test current, 126lm flux output) and mechanical dimensions (5.00mm x 5.00mm, 0.058" max height). The packaging format difference (Cut Tape & Digi-Reel® versus standard packaging) does not affect circuit performance or PCB layout.

Q: Why is MX6AWT-A1-R250-000DDZ listed as a substitute if it has different voltage and current ratings?

A: MX6AWT-A1-R250-000DDZ is classified as a similar substitute because it shares the same color (White, Cool 5000K), viewing angle (120°), physical dimensions (5.00mm x 5.00mm), and thermal characteristics (5°C/W). However, its different electrical parameters (3.3V Vf, 300mA test current) require circuit redesign. This part is suitable only when the application can be modified to accommodate lower forward voltage and higher test current.

Q: What is the difference between the two substitute parts?

A: MX6SWT-A1-R250-000FE3 is a parametric equivalent requiring no circuit changes. MX6AWT-A1-R250-000DDZ is a similar substitute from a different LED series (MX-6 versus MX-6S) with different electrical characteristics and active product status, requiring circuit redesign.

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

A: Yes. All three parts use 2-SMD Gull Wing packages with identical dimensions (5.00mm x 5.00mm) and maximum seated height (0.058" / 1.48mm). The MX6AWT-A1-R250-000DDZ features an exposed pad variant, which may provide improved thermal performance but does not prevent use with standard footprints.

Q: What is the MSL rating and handling requirement for these parts?

A: All three parts carry MSL 2A (4 Weeks) rating. This indicates the parts must be stored in controlled humidity conditions and used within 4 weeks of package opening. Standard moisture-sensitive device handling procedures apply.

Q: Does product status affect part selection?

A: Both MX6SWT-A1-R250-000FDZ and MX6SWT-A1-R250-000FE3 are obsolete, indicating limited future availability. MX6AWT-A1-R250-000DDZ is active, providing longer-term procurement stability if circuit redesign is feasible.
