SMLP36RGB1W3 Equivalent & Substitute Parts

Part Overview

The SMLP36RGB1W3 is an RGB diffused PicoLED surface mount LED from Rohm Semiconductor, featuring independent red, green, and blue emitters in a compact 0604 (1510 Metric) package. This part is classified as obsolete, making identification of compatible substitutes essential for ongoing production and maintenance applications. The RGB configuration with diffused lens provides uniform light distribution suitable for indicator applications requiring mixed-color output.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMLP36RGB1W3 is determined by the following critical parameters:

• Package compatibility: 0604 (1510 Metric) surface mount form factor
• Color configuration: Independent RGB emitters with matching wavelengths (Red 624nm, Green 527nm, Blue 470nm)
• Lens characteristics: Diffused white lens with rectangle flat-top geometry
• Mounting type: Surface mount technology
• Regulatory compliance: ROHS3 and REACH status alignment

The SMLP36RGBNW3 qualifies as a substitute based on identical package geometry, matching RGB wavelength specifications, equivalent mounting technology, and consistent regulatory compliance. Differences in forward voltage, luminous intensity, and product status are noted but do not preclude substitution where circuit design accommodates the parameter variations.

Parameter Comparison

Engineering Selection Recommendations

The SMLP36RGBNW3 is the primary substitute for the obsolete SMLP36RGB1W3. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and legacy system replacements.

The substitute part offers improved luminous intensity across all color channels (80mcd red, 220mcd green, 60mcd blue versus 28mcd, 45mcd, and 18mcd respectively) and lower forward voltage requirements. These characteristics provide enhanced brightness output and reduced power consumption in equivalent circuit configurations.

The active product status of SMLP36RGBNW3 ensures long-term availability and supply chain stability compared to the obsolete SMLP36RGB1W3. Height variation (0.30mm maximum versus 0.25mm) and lens size adjustment (1.50mm x 1.00mm versus 1.50mm x 0.60mm) require verification against PCB layout and mechanical clearance constraints.

Frequently Asked Questions (FAQ)

Q: Can SMLP36RGBNW3 be used as a direct replacement for SMLP36RGB1W3 in existing designs?

A: Substitution is feasible where circuit design accommodates lower forward voltages and higher luminous intensity. PCB layout must be verified for the increased maximum height (0.30mm) and adjusted lens dimensions (1.50mm x 1.00mm).

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

A: Primary differences include product status (active versus obsolete), forward voltage (lower in SMLP36RGBNW3), luminous intensity (higher in SMLP36RGBNW3), and physical dimensions (height and lens size). Wavelengths, package type, and regulatory compliance remain identical.

Q: Are the packaging options different between these parts?

A: SMLP36RGB1W3 packaging information is not specified in available data. SMLP36RGBNW3 is supplied in Tape & Reel (TR) format. Confirm packaging requirements with your procurement specifications.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both SMLP36RGB1W3 and SMLP36RGBNW3 are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for industrial and commercial applications.

Q: What is the impact of the lower forward voltage in SMLP36RGBNW3?

A: Lower forward voltage (1.9V red, 2.9V green, 2.95V blue versus 2.1V, 3.1V, 3.0V) reduces power dissipation and allows operation with lower supply voltages. Current-limiting resistor values may require adjustment to maintain equivalent brightness levels.

Q: Is the increased brightness of SMLP36RGBNW3 a concern for existing applications?

A: Higher luminous intensity (80mcd red, 220mcd green, 60mcd blue) may require circuit modifications to limit current or adjust resistor values if the original design relied on the lower brightness of SMLP36RGB1W3. Verify brightness requirements against application specifications.
