CCL-CRS10R LED Red Clear SMD Equivalent & Substitute Parts

Part Overview

The CCL-CRS10R is a red LED indication component manufactured by Lumex Opto/Components Inc., designed for discrete 2V surface mount applications in the 1208 (3020 Metric) package format. This part is classified as obsolete, necessitating identification of active equivalent components to maintain design continuity and ensure supply chain availability. The component features a clear colorless lens with a square flat-top design and 12mcd brightness rating, suitable for standard indicator applications requiring 180° viewing angle.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete CCL-CRS10R is determined by strict alignment of the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 1208 (3020 Metric) surface mount package to ensure PCB footprint compatibility without design modification.

Electrical Characteristics: Forward voltage (Vf), test current, and wavelength specifications must fall within acceptable operating ranges for the application circuit. The CCL-CRS10R operates at 2V typical forward voltage with 20mA test current and 635nm peak wavelength.

Optical Performance: Color (red), lens transparency (clear), and brightness rating (millicandela) define the visual indication function. Viewing angle affects the application's visibility requirements.

Regulatory Compliance: RoHS3 compliance and REACH unaffected status ensure environmental and regulatory alignment for modern manufacturing and distribution.

Mounting and Handling: Surface mount configuration and moisture sensitivity level (MSL) classification determine assembly process compatibility and storage requirements.

The substitute part 5973111507F from Dialight meets these substitution criteria within the allowed parameter tolerances for this product category.

Parameter Comparison

Engineering Selection Recommendations

The 5973111507F from Dialight is an active substitute for the obsolete CCL-CRS10R. Both components share identical package format (1208 / 3020 Metric), mounting type (surface mount), color (red), lens transparency (clear), and test current (20mA). Both maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

The substitute part operates at 1.75V typical forward voltage compared to the main part's 2V, representing a 0.25V reduction. The substitute provides 16mcd brightness versus 12mcd in the original, offering increased optical output. Peak wavelength differs at 660nm (substitute) versus 635nm (main part), both within the red spectrum range.

Viewing angle specification changes from 180° to 110°, indicating a narrower field of view in the substitute. Physical dimensions show the substitute is 0.54mm narrower (2.00mm versus 2.54mm width) and 0.30mm taller (1.50mm versus 1.20mm height). Moisture sensitivity level increases from 2A to 3, requiring adjusted storage protocols.

Selection of the 5973111507F requires circuit validation to confirm compatibility with the reduced forward voltage and modified viewing angle characteristics within the application's design parameters.

Frequently Asked Questions (FAQ)

Q: Can the 5973111507F directly replace the CCL-CRS10R without PCB modification?

A: Both components use the 1208 (3020 Metric) surface mount package with identical length (3.00mm) and mounting type. The substitute is 0.54mm narrower in width and 0.30mm taller in height. PCB footprint compatibility depends on the original design's dimensional tolerances. Physical clearance verification is required for height and width variations.

Q: What is the impact of the 0.25V forward voltage difference?

A: The substitute operates at 1.75V versus the original 2V. This difference affects circuit current-limiting resistor calculations and power supply requirements. The application circuit must be evaluated to confirm the lower forward voltage is compatible with existing current-limiting designs.

Q: How does the viewing angle change from 180° to 110° affect the application?

A: The 180° viewing angle of the original part provides full hemispherical visibility. The substitute's 110° viewing angle creates a narrower field of view, concentrating light output in a more focused direction. Applications requiring wide-angle indication may experience reduced visibility with the substitute.

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity level differs: the original is 2A (4 weeks storage), while the substitute is 3 (168 hours storage). The substitute requires more stringent moisture control during storage and handling.

Q: What is the brightness difference between 12mcd and 16mcd?

A: The substitute provides approximately 33% higher brightness output (16mcd versus 12mcd). This increased luminous intensity may affect visual perception in the application and could require circuit current adjustment if the original design relied on specific brightness characteristics.

Q: Does the wavelength difference (635nm versus 660nm) affect color perception?

A: Both wavelengths are in the red spectrum. The original at 635nm is slightly more orange-red, while the substitute at 660nm is a deeper red. The difference may be perceptible in direct comparison but typically remains within acceptable red indication standards.
