Substitute Part Grouping Explanation

The MSL0601RGBU1 is identified as a substitute for the MSL0201RGBW1S4 based on the following substitution criteria:

Preserved Electrical Parameters:

• Identical color configuration: Red, Green, Blue (RGB)
• Identical configuration type: Common Anode
• Identical mounting type: Surface Mount, Right Angle
• Identical wavelength specifications: 624nm Red, 527nm Green, 470nm Blue
• Compatible forward voltage ranges across all color channels

Allowed Mechanical Variations:

• Package type change: 4-SMD, No Lead (MSL0201RGBW1S4) to 2-SMD, No Lead (MSL0601RGBU1)
• Physical dimensions: 3.05mm × 1.30mm (MSL0201RGBW1S4) to 2.90mm × 1.35mm (MSL0601RGBU1)
• Height increase: 0.53mm (MSL0201RGBW1S4) to 1.10mm (MSL0601RGBU1)
• Lens color: No specification (MSL0201RGBW1S4) to White (MSL0601RGBU1)

Performance Differences:

• Millicandela ratings are higher in the substitute part
• Test current increased from 5mA to 20mA per color channel
• Moisture Sensitivity Level upgraded from 2A to 3

The MSL0601RGBU1 maintains functional RGB color indication capability with enhanced brightness characteristics and improved moisture handling.

Parameter Comparison

Engineering Selection Recommendations

The MSL0601RGBU1 is an active product with current manufacturing support and established supply chain availability (46,045 pcs in stock), whereas the MSL0201RGBW1S4 is obsolete with limited inventory (1,111 pcs). Both components maintain ROHS3 compliance and REACH unaffected status, meeting equivalent environmental and regulatory requirements.

Selection of the MSL0601RGBU1 as a substitute provides access to an actively manufactured component with superior brightness characteristics across all color channels. The substitute part maintains identical wavelength specifications and common anode configuration, ensuring functional compatibility in RGB indication applications. The increased test current (20mA vs. 5mA) and higher millicandela ratings reflect enhanced optical performance suitable for applications requiring greater visibility.

Design integration of the MSL0601RGBU1 requires accommodation of increased package height (1.10mm vs. 0.53mm) and modified forward voltage specifications for green and blue channels (3.3V and 3.2V vs. 3.0V and 2.9V). The package footprint reduction (2.90mm × 1.35mm vs. 3.05mm × 1.30mm) may provide layout benefits in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the MSL0601RGBU1 directly replace the MSL0201RGBW1S4 in existing designs?

A: The MSL0601RGBU1 maintains identical RGB color configuration, common anode topology, and surface mount right-angle orientation. However, design modifications are required to accommodate increased package height (1.10mm vs. 0.53mm), modified forward voltage specifications for green and blue channels, and increased operating current (20mA vs. 5mA per channel). PCB layout and current-limiting resistor values must be re-evaluated.

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

A: The MSL0601RGBU1 operates at higher forward voltages for green (3.3V vs. 3.0V) and blue (3.2V vs. 2.9V) channels, with red voltage remaining constant at 2.1V. Test current increases from 5mA to 20mA per color channel. These differences require recalculation of current-limiting resistor values in the circuit design.

Q: Are there mechanical compatibility concerns?

A: The MSL0601RGBU1 features a 2-SMD package versus the 4-SMD package of the MSL0201RGBW1S4, with increased height (1.10mm vs. 0.53mm). PCB footprint and clearance requirements must be re-evaluated. The slightly smaller lateral dimensions (2.90mm × 1.35mm vs. 3.05mm × 1.30mm) may provide layout advantages.

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

A: Both components are ROHS3 compliant and REACH unaffected. The MSL0601RGBU1 features improved moisture sensitivity level (MSL 3 vs. MSL 2A), providing enhanced protection during storage and handling.

Q: Why is the MSL0201RGBW1S4 obsolete?

A: The MSL0201RGBW1S4 is classified as obsolete by Rohm Semiconductor. The MSL0601RGBU1 represents the active product line continuation for RGB LED indication in this form factor category, with enhanced performance specifications and ongoing manufacturing support.
