Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMLP34RGB2W3 is determined by the following critical parameters:

• Package compatibility: 0404 (1010 Metric) surface mount form factor
• Configuration: Common anode RGB architecture
• Color wavelengths: 624nm Red, 527nm Green, 470nm Blue
• Electrical characteristics: Forward voltage and test current ratings per color element
• Mechanical dimensions: 1.00mm L x 1.00mm W footprint, 0.25mm maximum height
• Compliance: ROHS3 and REACH status

The SMLP34RGBN1W3 qualifies as a direct substitute based on matching package geometry, common anode configuration, identical wavelength specifications, and equivalent mounting characteristics. Both parts share the same base product number (SMLP34) and maintain compliance with applicable environmental standards.

Parameter Comparison

Engineering Selection Recommendations

The SMLP34RGBN1W3 is the designated substitute for the obsolete SMLP34RGB2W3. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and legacy system updates.

The substitute part exhibits lower forward voltage specifications across red and green elements (0.2V reduction each) while maintaining identical blue channel voltage. The SMLP34RGBN1W3 provides increased luminous intensity across all color channels, with notably higher millicandela ratings. These electrical and optical differences require circuit-level validation to confirm compatibility with existing driver designs and brightness requirements.

The substitute part is currently in active production status, ensuring long-term availability and supply chain stability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the SMLP34RGBN1W3 be used as a direct pin-for-pin replacement?

A: Yes. Both parts share identical package geometry (0404 / 1010 Metric), common anode configuration, and matching footprint dimensions (1.00mm L x 1.00mm W, 0.25mm height). PCB layout compatibility is maintained.

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

A: The substitute part operates at lower forward voltages: 1.9V Red and 2.9V Green versus 2.1V Red and 3.1V Green in the original. Blue channel voltage remains at 3V. Test current specifications are identical at 5mA per color element. Circuit designs must account for the reduced voltage drop when selecting current-limiting resistor values.

Q: Are there optical performance differences?

A: Yes. The SMLP34RGBN1W3 provides higher luminous intensity across all channels: 80mcd Red (versus 35mcd), 220mcd Green (versus 110mcd), and 60mcd Blue (versus 45mcd). Lens size differs slightly: 1.00mm x 1.00mm versus 1.00mm x 0.60mm in the original. Applications requiring specific brightness levels must validate performance against design specifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, maintaining equivalent environmental and regulatory status.

Q: What is the availability status of each part?

A: The SMLP34RGB2W3 is obsolete with limited inventory. The SMLP34RGBN1W3 is in active production status with higher stock availability, supporting long-term procurement requirements.
