Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MX3SWT-A1-0000-000BA3 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Color: White, Neutral
• CCT (Correlated Color Temperature): 4300K
• Viewing Angle: 120°
• Mounting Type: Surface Mount
• Package / Case: 2-SMD, Gull Wing Exposed Pad
• Physical Dimensions: 5.00 mm × 5.00 mm footprint
• Height - Seated (Max): 1.48 mm

Allowable Variation Parameters:

• Forward Voltage (Vf): Substitutes may differ based on series generation
• Test Current: Substitutes may operate at different rated currents
• Flux Output: Substitutes must maintain neutral white 4300K color point
• Lumens/Watt Efficiency: Newer generations typically provide improved efficiency
• Maximum Current Rating: May vary by series

The XLamp® MX-3 series (MX3AWT-A1-0000-000CA3) qualifies as a substitute based on matching color, CCT, viewing angle, mounting type, and physical package dimensions. Electrical parameter differences reflect the advancement from MX-3S to MX-3 generation technology.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000CA3 is the designated substitute for the obsolete MX3SWT-A1-0000-000BA3 based on the following engineering criteria:

Product Status Alignment: The substitute part carries Active product status, ensuring ongoing availability and manufacturer support, whereas the main part is classified as Obsolete.

Compliance & Certifications: Both parts maintain REACH Unaffected status and EAR99 ECCN classification. The substitute part additionally carries RoHS Compliant certification, meeting current regulatory requirements for electronic components in regulated markets.

Optical & Thermal Equivalency: Both parts deliver identical color characteristics (White, Neutral 4300K), CRI (75 Typ), viewing angle (120°), and thermal resistance (11°C/W). The substitute provides marginally higher flux output (104 lm vs. 97 lm) while maintaining equivalent lumens/watt efficiency (80 lm/W vs. 79 lm/W).

Mechanical & Package Compatibility: Identical footprint (5.00 mm × 5.00 mm), height (1.48 mm max), mounting type (Surface Mount), and package configuration (2-SMD, Gull Wing Exposed Pad) ensure direct PCB compatibility without layout modifications.

Electrical Parameter Differences: The substitute operates at lower forward voltage (3.7V vs. 10.7V) and higher test current (350 mA vs. 115 mA). Circuit designs must be evaluated to accommodate these electrical differences. Maximum current rating increases from 175 mA to 500 mA, providing greater operational headroom.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000CA3 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000BA3?

A: Mechanical and optical compatibility is direct. The parts share identical footprint, height, color, CCT, CRI, and viewing angle. However, electrical parameters differ significantly: forward voltage drops from 10.7V to 3.7V, and test current increases from 115 mA to 350 mA. Circuit redesign is required to accommodate these electrical differences.

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

A: Substitution is determined by matching color (White, Neutral), CCT (4300K), viewing angle (120°), mounting type (Surface Mount), package configuration (2-SMD, Gull Wing Exposed Pad), and physical dimensions (5.00 mm × 5.00 mm footprint, 1.48 mm max height). Electrical parameters (Vf, test current, maximum current) may vary between generations.

Q: Why does the substitute part have different forward voltage and current ratings?

A: The MX3AWT-A1-0000-000CA3 represents a newer generation (MX-3) within the XLamp® product line compared to the obsolete MX-3S series. Technological improvements in LED die design and packaging result in lower forward voltage and higher current capacity while maintaining equivalent optical performance.

Q: Are there any compliance or regulatory differences between the two parts?

A: Both parts maintain REACH Unaffected status and EAR99 ECCN classification. The substitute part carries additional RoHS Compliant certification, meeting current environmental and regulatory standards for electronic components in regulated jurisdictions.

Q: What packaging formats are available for the substitute part?

A: The MX3AWT-A1-0000-000CA3 is supplied in Tape & Reel (TR) format. The main part packaging format was not specified in the available data.

Q: Are the thermal characteristics equivalent between the two parts?

A: Yes. Both parts maintain identical thermal resistance of 11°C/W and identical moisture sensitivity level (MSL 2A, 4 Weeks), ensuring equivalent thermal management and handling requirements.
