Substitute Part Grouping Explanation

Substitution of the obsolete MX3SWT-A1-0000-000DB1 is determined by the following critical parameters:

Mechanical Compatibility:

Package type: 2-SMD, Gull Wing Exposed Pad
Physical dimensions: 5.00 mm × 5.00 mm footprint
Height: 1.48 mm maximum seated height
Mounting type: Surface Mount

Optical Compatibility:

Color: White
Viewing angle: 120°

Electrical Compatibility:

Flux output: 111 lm nominal (107–114 lm acceptable range)
Forward voltage tolerance and current rating must support circuit design requirements

The MX6AWT-A1-0000-000DB1 qualifies as a substitute based on identical mechanical package, optical characteristics, and flux output specification. However, significant differences in forward voltage (3.3V vs. 10.7V) and test current (300mA vs. 115mA) require circuit redesign and are not pin-compatible without modification.

Engineering Selection Recommendations

The MX6AWT-A1-0000-000DB1 is the identified substitute for the obsolete MX3SWT-A1-0000-000DB1 based on matching mechanical package, optical specifications, and flux output. The substitute part is currently in active production status with RoHS compliance certification, supporting long-term supply chain stability.

Critical design considerations for substitution:

Electrical Redesign Required: Forward voltage differs significantly (3.3V vs. 10.7V). Current-limiting circuit topology and power supply voltage must be recalculated to maintain 111 lm flux output at the substitute part's 300mA test current specification.

Thermal Performance: The substitute part exhibits superior thermal resistance (5°C/W vs. 11°C/W), reducing junction temperature rise and improving reliability in thermally constrained applications.

Compliance: The substitute part carries RoHS compliance certification, whereas the original part status is not specified. This supports regulatory compliance for new designs and production runs.

Both parts share identical mechanical footprint, package type, and MSL rating, enabling direct PCB layout reuse without modification.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000DB1 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000DB1?

A: No. While both parts share identical mechanical package dimensions and optical characteristics, the forward voltage and test current specifications differ substantially. Direct substitution without circuit modification will result in incorrect LED current and potential component damage. Circuit redesign is required.

Q: What are the key differences between these two parts?

A: The primary differences are forward voltage (10.7V vs. 3.3V), test current (115mA vs. 300mA), and thermal resistance (11°C/W vs. 5°C/W). Both deliver 111 lumens at their respective test currents and share identical 5.00 mm × 5.00 mm footprints with 120° viewing angles.

Q: Why is the MX3SWT-A1-0000-000DB1 marked as obsolete?

A: Product status reflects manufacturer lifecycle decisions. The XLamp® MX-6 series (MX6AWT-A1-0000-000DB1) represents the current generation technology with improved efficiency (112 lm/W vs. 90 lm/W) and thermal performance.

Q: Are there any packaging differences between these parts?

A: The main part is supplied in standard packaging. The substitute part is available in Tape & Reel (TR) format. Both use identical 2-SMD, Gull Wing Exposed Pad package type with matching mechanical dimensions and MSL 2A (4 Weeks) rating.

Q: What is the impact of the thermal resistance difference?

A: The substitute part's lower thermal resistance (5°C/W vs. 11°C/W) results in reduced junction temperature rise for the same power dissipation. This improves LED lifespan and light output stability in applications with elevated ambient temperatures or thermal constraints.

Q: Does the substitute part meet RoHS requirements?

A: Yes. The MX6AWT-A1-0000-000DB1 is RoHS Compliant. The original part's RoHS status is not specified in available documentation.
