MSL0201RGBW1S2 Equivalent & Substitute Parts

Part Overview

The MSL0201RGBW1S2 is an RGB LED indicator from Rohm Semiconductor's PicoLED™ series, featuring red (624nm), green (527nm), and blue (470nm) wavelengths in a compact 4-SMD, no-lead surface mount package with right-angle configuration. The component is classified as obsolete, necessitating identification of active alternative parts that maintain functional compatibility for RGB indication applications. Substitute parts must preserve the common anode configuration, RGB color output, and surface mount right-angle mounting characteristics while accommodating differences in package density, brightness ratings, and electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MSL0201RGBW1S2 is based on the following critical parameters that must be preserved or compatible:

• RGB color output with matching wavelengths (624nm Red, 527nm Green, 470nm Blue)
• Common anode configuration for circuit compatibility
• Surface mount right-angle mounting orientation
• Forward voltage compatibility within typical design tolerances
• RoHS3 compliance and REACH unaffected status

The MSL0601RGBU1 qualifies as a substitute based on matching RGB wavelengths, common anode configuration, and surface mount right-angle mounting. Differences in package density (2-SMD vs. 4-SMD), brightness ratings, forward voltages, and test current reflect the evolution from the PicoLED™ series to the active MSL series, with the substitute offering higher brightness capability and active product status.

Parameter Comparison

Engineering Selection Recommendations

The MSL0601RGBU1 is the designated substitute for the obsolete MSL0201RGBW1S2 based on the following criteria:

• Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity
• RGB wavelength specifications are identical across all three color channels
• Common anode configuration is preserved, maintaining circuit-level compatibility
• Surface mount right-angle orientation is consistent between both parts
• The MSL0601RGBU1 holds active product status, ensuring long-term availability and supply chain stability

Design considerations for substitution include accommodation of increased forward voltages (green and blue channels), higher test current requirements (20mA vs. 5mA), and significantly higher brightness ratings. Circuit designs must be evaluated for current-limiting resistor adjustments and power supply capacity. The MSL0601RGBU1 features a 2-SMD package versus the 4-SMD configuration of the original part, resulting in reduced footprint and increased height, requiring PCB layout verification.

Frequently Asked Questions (FAQ)

Q: Can the MSL0601RGBU1 be used as a direct pin-for-pin replacement for the MSL0201RGBW1S2?

A: The MSL0601RGBU1 maintains common anode configuration and RGB color output, but differs in package type (2-SMD vs. 4-SMD) and physical dimensions. PCB layout modifications are required. Forward voltage and test current specifications differ, necessitating circuit design review for current-limiting resistor values.

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

A: The MSL0601RGBU1 operates at higher forward voltages (3.3V green, 3.2V blue vs. 3.0V and 2.9V respectively) and requires 20mA test current versus 5mA for the MSL0201RGBW1S2. Brightness ratings are substantially higher across all color channels in the substitute part.

Q: Are both parts RoHS compliant?

A: Yes, both the MSL0201RGBW1S2 and MSL0601RGBU1 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the impact of the package change from 4-SMD to 2-SMD?

A: The 2-SMD package of the MSL0601RGBU1 reduces the footprint (2.90mm x 1.35mm vs. 3.05mm x 1.30mm) but increases component height (1.10mm vs. 0.53mm). PCB design must accommodate the increased height and modified lead configuration.

Q: How does the MSL rating difference affect component handling?

A: The MSL0201RGBW1S2 carries a 2A rating (4 weeks), while the MSL0601RGBU1 carries a 3 rating (168 hours). Both require controlled storage conditions, with the substitute part allowing extended storage periods under MSL3 conditions.
