Key Parameters

Substitute Part Grouping Explanation

Substitution of the CL-425F-V-SD-TS is determined by the following critical parameters:

Package and Mounting Compatibility: Both the main part and substitute must utilize 4-SMD, No Lead packaging with surface mount, right-angle mounting to ensure mechanical and electrical compatibility with existing PCB layouts.

Color Configuration: RGB tri-color LED functionality must be maintained. Both parts provide discrete Red, Green, and Blue channels.

Electrical Operating Parameters: Forward voltage specifications and test current ratings establish the substitution boundary. The CL-425F-V-SD-TS operates at 1.85V Red, 3.1V Green, and 2.9V Blue at 5mA test current.

Physical Dimensions: Lens size and component height are critical for space-constrained applications. The CL-425F-V-SD-TS measures 3.25mm L x 0.45mm W with a maximum height of 0.45mm.

Regulatory Compliance: REACH status and ECCN classification must align with application requirements.

The CL-426F-AACC-SD-TS is identified as a substitute part based on matching package type, mounting configuration, color functionality, and regulatory compliance. However, this substitute operates under a common cathode configuration, differs in forward voltage specifications, and features different physical dimensions and luminous intensity ratings.

Parameter Comparison

Engineering Selection Recommendations

The CL-425F-V-SD-TS is classified as obsolete. The CL-426F-AACC-SD-TS is an active product from the same manufacturer (Citizen) and represents the available substitute option.

Key Differences Requiring Circuit Redesign:

The CL-426F-AACC-SD-TS operates under a common cathode configuration, whereas the CL-425F-V-SD-TS uses common anode architecture. This fundamental difference requires modification of the drive circuit and control logic. Forward voltage specifications differ across all color channels: Red increases from 1.85V to 2V, Green decreases from 3.1V to 2.7V, and Blue decreases from 2.9V to 2.8V. These variations necessitate recalculation of current-limiting resistor values.

Physical Dimension Variations:

The CL-426F-AACC-SD-TS is smaller in both lateral dimensions (2.80mm L x 0.35mm W versus 3.25mm L x 0.45mm W) and height (0.35mm versus 0.45mm). Space-constrained applications may benefit from this reduction, but existing PCB layouts designed for the CL-425F-V-SD-TS may require modification.

Luminous Intensity Differences:

The CL-426F-AACC-SD-TS provides higher luminous intensity across all color channels: Red increases from 20mcd to 120mcd, Green increases from 180mcd to 250mcd, and Blue increases from 45mcd to 62mcd. Applications requiring specific brightness levels must account for these changes.

Regulatory and Compliance Status:

Both parts maintain identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS codes (8541.41.0000). The CL-426F-AACC-SD-TS carries RoHS Compliant certification, whereas the CL-425F-V-SD-TS does not specify RoHS status. Both maintain MSL Rating 3 (168 Hours) moisture sensitivity levels.

Frequently Asked Questions (FAQ)

Q: Can the CL-426F-AACC-SD-TS be used as a direct replacement for the CL-425F-V-SD-TS without circuit modification?

A: No. The CL-426F-AACC-SD-TS operates under common cathode configuration while the CL-425F-V-SD-TS uses common anode architecture. Forward voltage specifications differ across all color channels. Circuit redesign is required, including modification of drive logic and current-limiting resistor values.

Q: What are the physical compatibility considerations?

A: The CL-426F-AACC-SD-TS is smaller than the CL-425F-V-SD-TS in all dimensions. Lens size reduces from 3.25mm L x 0.45mm W to 2.80mm L x 0.35mm W, and height reduces from 0.45mm to 0.35mm. Existing PCB layouts designed for the CL-425F-V-SD-TS may require modification to accommodate the smaller component.

Q: How do the luminous intensity ratings compare?

A: The CL-426F-AACC-SD-TS provides higher brightness across all color channels. Red increases from 20mcd to 120mcd, Green increases from 180mcd to 250mcd, and Blue increases from 45mcd to 62mcd. Applications requiring specific brightness levels must account for these increases.

Q: Are there differences in forward voltage specifications?

A: Yes. Red forward voltage increases from 1.85V to 2V, Green forward voltage decreases from 3.1V to 2.7V, and Blue forward voltage decreases from 2.9V to 2.8V. These variations require recalculation of current-limiting resistor values to maintain proper LED operation at the specified 5mA test current.

Q: What is the packaging difference between these parts?

A: The CL-425F-V-SD-TS is supplied in standard packaging, while the CL-426F-AACC-SD-TS is supplied in Tape & Reel (TR) format. Both utilize 4-SMD, No Lead package type with surface mount, right-angle mounting configuration.

Q: Are both parts compliant with regulatory requirements?

A: Both parts maintain REACH Unaffected status and EAR99 ECCN classification. The CL-426F-AACC-SD-TS carries RoHS Compliant certification. Both maintain MSL Rating 3 (168 Hours) moisture sensitivity levels.

Q: What is the product status difference?

A: The CL-425F-V-SD-TS is classified as obsolete. The CL-426F-AACC-SD-TS is an active product, ensuring ongoing availability and support from the manufacturer.
