Substitute Part Grouping Explanation

The MSL0104RGBU1 qualifies as a direct substitute for the MSL0101RGBU1 based on strict parametric equivalence across all critical electrical and mechanical specifications. Substitution is valid when the following parameters match identically:

• Dominant wavelengths: 624nm Red, 527nm Green, 470nm Blue
• Forward voltages: 2.1V Red, 3.3V Green, 3.2V Blue
• Test current: 20mA per color channel
• Luminous intensity: 700mcd Red, 1200mcd Green, 400mcd Blue
• Lens configuration: Diffused, rectangle with flat top, 5.40mm x 1.60mm
• Mounting type: Surface mount, right angle
• Package type: 7-SMD, flat lead (2709 metric)
• Physical envelope: 6.90mm L x 2.20mm W x 2.15mm max height
• Compliance: ROHS3, MSL 3

The primary distinction is product status: MSL0101RGBU1 is obsolete, while MSL0104RGBU1 maintains active status with significantly higher inventory availability.
