MSL0201RGBW1 Equivalent & Substitute Parts

Part Overview

The MSL0201RGBW1 is an RGB diffused PicoLED surface mount indicator from Rohm Semiconductor, featuring red (624nm), green (527nm), and blue (470nm) emitters in a common anode configuration. This component is classified as obsolete, necessitating identification of active alternative parts for new designs and ongoing production requirements. The part operates at 2.1V red, 3V green, and 2.9V blue with 5mA test current across all channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSL0201RGBW1 is determined by the following critical parameters:

• Color Configuration: RGB common anode architecture
• Mounting Type: Surface mount, right angle orientation
• Package Type: SMD, no lead configuration
• Wavelength Compatibility: Red (620-630nm), Green (520-530nm), Blue (465-475nm)
• Forward Voltage Range: Red (2.0-2.2V), Green (2.9-3.3V), Blue (2.8-3.2V)
• Compliance: ROHS3 compliant, REACH unaffected

Two substitute parts meet these criteria with varying trade-offs in brightness, current requirements, and physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

MSL0601RGBU1 (Rohm Semiconductor, Active Status)

This part maintains identical wavelength specifications (624nm red, 527nm green, 470nm blue) and forward voltage compatibility with the MSL0201RGBW1. The MSL0601RGBU1 operates at 20mA test current versus 5mA for the original part, delivering significantly higher brightness (700mcd red, 1250mcd green, 360mcd blue). Physical dimensions are comparable (2.90mm x 1.35mm versus 3.00mm x 1.30mm), with increased height (1.10mm versus 0.43mm). This part is actively manufactured and ROHS3 compliant with improved moisture sensitivity (MSL 3 versus MSL 4). Selection is appropriate for applications requiring higher luminous intensity with standard RGB color reproduction.

LTST-C19FD1WT (Lite-On Inc., Active Status)

This part substitutes the red emitter with orange (605nm) while maintaining green (525nm) and blue (470nm) wavelengths. Forward voltage differs across channels (2V orange, 4.6V green, 4.6V blue), requiring circuit redesign for voltage compensation. The LTST-C19FD1WT operates at 20mA test current with moderate brightness (113mcd orange, 261mcd green, 104mcd blue). Physical dimensions are smaller (2.10mm x 1.60mm) with height of 0.55mm. This part is actively manufactured, ROHS3 compliant, and includes specified viewing angle (130°). Selection is appropriate only when orange color substitution for red is functionally acceptable and circuit voltage adjustment is feasible.

Frequently Asked Questions (FAQ)

Q: Can MSL0601RGBU1 directly replace MSL0201RGBW1 without circuit modification?

A: The MSL0601RGBU1 maintains identical wavelength specifications and forward voltage ranges, enabling direct substitution in most applications. However, the increased test current (20mA versus 5mA) requires verification that current-limiting resistors and driver circuits can supply the higher current without exceeding component ratings.

Q: What are the key differences between MSL0201RGBW1 and MSL0601RGBU1?

A: Both parts share identical RGB wavelengths and common anode configuration. Primary differences are brightness (MSL0601RGBU1 is approximately 8-14x brighter), test current (20mA versus 5mA), physical height (1.10mm versus 0.43mm), and product status (active versus obsolete). Forward voltage for green and blue channels is slightly elevated in the MSL0601RGBU1 (3.3V and 3.2V versus 3V and 2.9V).

Q: Is LTST-C19FD1WT a suitable substitute for MSL0201RGBW1?

A: LTST-C19FD1WT substitutes orange for red, altering the color palette from RGB to BGO (blue, green, orange). This part is suitable only when orange indication is functionally equivalent to red in the application. Forward voltage differences require circuit redesign for proper current limiting across all channels.

Q: What is the impact of MSL rating differences between these parts?

A: MSL0201RGBW1 has MSL 4 (72-hour floor life), while both substitute parts have MSL 3 (168-hour floor life). MSL 3 provides extended handling time before reflow soldering, reducing production risk and improving supply chain flexibility. This represents an improvement in manufacturing processability.

Q: Are all three parts ROHS3 compliant?

A: Yes. MSL0201RGBW1, MSL0601RGBU1, and LTST-C19FD1WT are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: How do physical dimensions affect PCB layout compatibility?

A: MSL0201RGBW1 measures 3.00mm x 1.30mm x 0.43mm height. MSL0601RGBU1 is 2.90mm x 1.35mm x 1.10mm height, requiring verification of vertical clearance in confined spaces. LTST-C19FD1WT is 2.10mm x 1.60mm x 0.55mm height, offering the smallest footprint but widest lateral dimension. PCB land pattern compatibility must be confirmed before substitution.
