Key Parameters

Substitute Part Grouping Explanation

Substitution of the CL-425F-C1CC-SD-TS is determined by the following critical parameters:

Configuration Compatibility:

• Common cathode architecture (required match)
• RGB color configuration with discrete red, green, and blue elements (required match)
• Surface mount right-angle mounting type (required match)
• 4-SMD, no-lead package format (required match)

Electrical Compatibility:

• Forward voltage ranges for each color channel
• Test current specifications (5mA per channel)
• Moisture sensitivity level classification

Physical Compatibility:

• Lens style (rectangle with flat top)
• Overall package dimensions and height constraints
• SMD footprint compatibility

The CL-426F-AACC-SD-TS meets these substitution criteria as an active product from the same manufacturer with identical configuration, mounting type, and package format.

Engineering Selection Recommendations

Primary Substitute: CL-426F-AACC-SD-TS

The CL-426F-AACC-SD-TS is the recommended substitute for the obsolete CL-425F-C1CC-SD-TS based on the following factors:

Product Status: The CL-426F-AACC-SD-TS maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity.

Compliance: The substitute part carries RoHS Compliant certification and REACH Unaffected status, meeting modern regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS classifications.

Configuration Alignment: Both parts maintain identical common cathode RGB configuration, surface mount right-angle mounting, and 4-SMD no-lead package format, ensuring direct PCB footprint compatibility.

Electrical Parameters: Forward voltage specifications differ marginally across color channels (red channel increases from 1.85V to 2V; blue channel increases from 2.5V to 2.8V; green channel remains at 2.7V). Test current specifications remain constant at 5mA per channel. Circuit designs must accommodate these voltage variations through resistor value adjustments.

Optical Performance: The CL-426F-AACC-SD-TS delivers higher luminous intensity across all color channels (120mcd red vs. 20mcd, 250mcd green vs. 180mcd, 62mcd blue vs. 45mcd), providing enhanced visibility in the same physical form factor.

Physical Dimensions: The substitute part features reduced lens dimensions (2.80mm x 0.35mm vs. 3.25mm x 0.45mm) and lower maximum height (0.35mm vs. 0.45mm), offering improved space efficiency in compact designs.

Frequently Asked Questions (FAQ)

Q: Can the CL-426F-AACC-SD-TS be used as a direct drop-in replacement for the CL-425F-C1CC-SD-TS?

A: The CL-426F-AACC-SD-TS shares identical PCB footprint compatibility due to matching 4-SMD no-lead package format and surface mount right-angle configuration. However, circuit design modifications are required to accommodate forward voltage differences, particularly for the red channel (1.85V to 2V) and blue channel (2.5V to 2.8V). Current-limiting resistor values must be recalculated based on the new forward voltage specifications.

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

A: Primary differences include product status (obsolete vs. active), forward voltage specifications across color channels, luminous intensity ratings, physical dimensions, and regulatory compliance certifications. The CL-426F-AACC-SD-TS provides higher brightness output in a more compact package with enhanced regulatory compliance.

Q: Are there any compatibility concerns with existing PCB designs?

A: PCB footprint compatibility is maintained due to identical package format and mounting type. However, circuit schematic modifications are necessary to accommodate the forward voltage changes. Designs must be re-evaluated for current-limiting resistor values and power supply voltage adequacy.

Q: What is the significance of the higher millicandela ratings in the substitute part?

A: The CL-426F-AACC-SD-TS delivers increased luminous intensity across all color channels, resulting in brighter LED indication at identical test current levels (5mA). This enhancement may require optical design review if the original design relied on specific brightness characteristics.

Q: Does the smaller lens size affect optical performance?

A: The CL-426F-AACC-SD-TS features reduced lens dimensions (2.80mm x 0.35mm vs. 3.25mm x 0.45mm). While the smaller lens maintains the rectangle with flat top style, optical beam characteristics and viewing angle performance may differ. Application-specific optical requirements must be evaluated.

Q: Are both parts subject to the same moisture sensitivity requirements?

A: Both parts carry identical Moisture Sensitivity Level 3 (168 Hours) classification, requiring equivalent handling, storage, and reflow soldering procedures during manufacturing.

Q: What regulatory advantages does the substitute part offer?

A: The CL-426F-AACC-SD-TS carries RoHS Compliant and REACH Unaffected certifications, meeting current environmental and regulatory standards. Both parts maintain identical ECCN (EAR99) export classification.
