Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000BE5 is based on the following electrical and mechanical compatibility criteria:

Primary Substitution Criteria:

• Color and correlated color temperature (CCT): White, Neutral 4000K
• Viewing angle: 120°
• Package type: 2-SMD, Gull Wing Exposed Pad
• Physical dimensions: 5.00 mm × 5.00 mm footprint
• Thermal resistance: 11°C/W
• Moisture sensitivity level: 2A (4 Weeks)
• Mounting type: Surface Mount

Secondary Considerations:

• CRI (Color Rendering Index): 80 (Typ)
• REACH compliance status
• Supplier device package classification: SMD

The substitute part MX3AWT-A1-0000-000CA4 meets all primary mechanical and optical compatibility requirements. However, electrical parameters (forward voltage and test current) differ significantly and must be evaluated against circuit design specifications.

Parameter Comparison

Engineering Selection Recommendations

Mechanical Compatibility: The MX3AWT-A1-0000-000CA4 is mechanically and optically compatible with the MX3SWT-A1-0000-000BE5. Both components share identical package geometry, footprint dimensions, thermal resistance, and moisture sensitivity classification, enabling direct PCB-level substitution without layout modifications.

Product Status Advantage: The substitute part carries Active product status, ensuring long-term availability and supply chain continuity. The main part's Obsolete classification necessitates transition planning.

Compliance Status: Both components maintain REACH Unaffected status. The substitute part additionally carries RoHS Compliant certification, providing enhanced regulatory alignment for applications subject to RoHS requirements.

Electrical Parameter Differences: The substitute part operates at significantly lower forward voltage (3.7V vs. 10.7V) and higher test current (350mA vs. 115mA). Circuit design modifications are required to accommodate these electrical differences. Power dissipation and thermal management characteristics will change accordingly.

Optical Performance: Both components deliver equivalent luminous efficacy (79–80 lm/W) and identical CRI (80 Typ). The substitute part produces slightly higher flux output (104 lm vs. 97 lm) at its specified test current.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000CA4 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000BE5?

A: Mechanical and optical compatibility is confirmed. However, electrical parameters differ substantially. The substitute part requires circuit redesign to accommodate lower forward voltage (3.7V vs. 10.7V) and higher operating current (350mA vs. 115mA). PCB layout remains compatible without modification.

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

A: The primary differences are forward voltage, test current, and product status. The MX3SWT operates at 10.7V/115mA and is obsolete. The MX3AWT operates at 3.7V/350mA and maintains active production status. Both share identical package geometry, thermal characteristics, and color specifications.

Q: Are there any compliance or regulatory differences?

A: Both parts maintain REACH Unaffected status. The substitute part (MX3AWT) carries RoHS Compliant certification, while the main part's RoHS status is not specified. For applications requiring RoHS compliance, the substitute part provides documented certification.

Q: What is the impact on thermal management?

A: Both components have identical thermal resistance (11°C/W) and identical package dimensions. However, power dissipation will differ due to electrical parameter changes. At rated current, the MX3AWT dissipates approximately 1.3W (3.7V × 350mA) compared to approximately 1.2W for the MX3SWT (10.7V × 115mA).

Q: Is the packaging format identical?

A: Yes. Both components use 2-SMD, Gull Wing Exposed Pad packaging with 5.00 mm × 5.00 mm footprint and 1.48 mm maximum seated height. Moisture sensitivity level (2A, 4 Weeks) is identical for both parts.

Q: What is the availability status of each part?

A: The MX3SWT-A1-0000-000BE5 is classified as Obsolete with 1069 units in current inventory. The MX3AWT-A1-0000-000CA4 maintains Active product status with 840 units in inventory, ensuring continued supply chain access.
