Key Parameters

Substitute Part Grouping Explanation

Substitution of the CCL-CRS10Y is determined by the following critical parameters:

Electrical Compatibility:

• Forward voltage (Vf) of 2.1V must be maintained
• Test current of 20mA establishes the operational baseline
• Peak wavelength of 585nm defines the yellow spectral output

Optical Compatibility:

• Yellow color specification
• Clear lens transparency
• Millicandela rating determines brightness level

Physical & Mechanical Compatibility:

• Surface mount mounting type
• Package form factor and dimensions
• Height constraints for PCB assembly

Regulatory & Compliance:

• RoHS3 compliance requirement
• REACH unaffected status

The substitute part SML-LX2832YC-TR maintains electrical parameters (2.1V forward voltage, 20mA test current, 585nm peak wavelength) and optical characteristics (yellow color, clear lens) while differing in package configuration, brightness rating, and viewing angle.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The SML-LX2832YC-TR is electrically compatible with the CCL-CRS10Y, maintaining identical forward voltage (2.1V), test current (20mA), and peak wavelength (585nm). Both components are ROHS3 compliant and REACH unaffected, satisfying regulatory requirements.

Design Considerations:

1. Package Transition: The substitute requires transition from 4-SMD, No Lead to 2-PLCC package. PCB layout and footprint redesign is necessary.

2. Physical Dimensions: The SML-LX2832YC-TR has increased height (2.10mm vs. 1.20mm) and slightly larger footprint (3.20mm x 2.80mm vs. 3.00mm x 2.54mm). Verify clearance in existing mechanical assemblies.

3. Optical Performance: The substitute provides higher brightness (15mcd vs. 8mcd) with reduced viewing angle (120° vs. 180°). Evaluate application requirements for visibility and directional characteristics.

4. Product Status: The substitute is active production status, ensuring long-term availability and supply chain continuity compared to the obsolete CCL-CRS10Y.

5. Packaging Format: The substitute is supplied in Tape & Reel format, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the SML-LX2832YC-TR directly replace the CCL-CRS10Y without circuit modifications?

A: Electrical parameters are identical (2.1V forward voltage, 20mA test current), allowing direct circuit-level substitution. However, PCB footprint redesign is required due to package change from 4-SMD, No Lead to 2-PLCC.

Q: What are the key differences between these components?

A: Primary differences are package configuration (4-SMD vs. 2-PLCC), brightness rating (8mcd vs. 15mcd), viewing angle (180° vs. 120°), and physical dimensions. Electrical and optical wavelength specifications are identical.

Q: Is the increased brightness of the SML-LX2832YC-TR suitable for all applications?

A: The higher brightness (15mcd) may require circuit current limiting adjustment depending on application requirements. Verify that the design can accommodate increased luminous intensity.

Q: What is the impact of the reduced viewing angle on visibility?

A: The SML-LX2832YC-TR has a 120° viewing angle compared to 180° for the CCL-CRS10Y. Applications requiring wide-angle visibility may require design evaluation or multiple component placement.

Q: Are both components RoHS compliant?

A: Yes, both the CCL-CRS10Y and SML-LX2832YC-TR are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory standards.

Q: What is the significance of the product status difference?

A: The CCL-CRS10Y is obsolete, indicating discontinued production. The SML-LX2832YC-TR is active production status, ensuring availability for new designs and ongoing production requirements.

Q: Does the packaging format affect component selection?

A: The SML-LX2832YC-TR is supplied in Tape & Reel format, optimized for automated assembly. The CCL-CRS10Y was supplied in bulk format. Tape & Reel packaging is standard for high-volume production environments.
