CLMUC-FKA RGB LED 4-SMD Equivalent & Substitute Parts

Part Overview

The CLMUC-FKA is a surface-mount RGB LED in 4-SMD J-Lead packaging manufactured by CreeLED, Inc. This component provides discrete red, green, and blue light emission with common anode configuration, designed for LED indication applications. The part is currently obsolete, making equivalent substitute components necessary for ongoing production and maintenance applications. The CLMUC-FKA operates at 1.9V forward voltage for red, 3V for green, and 3V for blue at 5mA test current.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CLMUC-FKA is determined by the following critical parameters:

Mandatory Matching Criteria:

• Configuration: Common Anode
• Package Type: 4-SMD, J-Lead (4-PLCC)
• Mounting Type: Surface Mount
• Physical Dimensions: 1.50mm L × 1.50mm W × 1.10mm H (Max)
• Color Configuration: Red, Green, Blue (RGB)
• Wavelength specifications: 622nm Red, 528nm Green, 468nm Blue

Allowable Variation Parameters:

• Forward Voltage (Vf): Minor variations within typical operating ranges
• Millicandela Rating: Variations within acceptable brightness tolerances
• Product Status: Active status preferred for ongoing availability

The CLMUC-FKA RGB LED 4-SMD can be substituted with components that maintain identical package geometry, configuration, wavelength specifications, and mounting characteristics while operating within compatible electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The CLMUD-FKA is a direct substitute for the obsolete CLMUC-FKA. Both components share identical package geometry, configuration, wavelength specifications, and mounting characteristics. The CLMUD-FKA maintains REACH compliance and EAR99 export classification consistent with the original part.

The primary advantage of the CLMUD-FKA is its active product status, ensuring ongoing availability and supply chain continuity. Forward voltage variations are minimal: green forward voltage is 0.2V lower (2.8V vs 3V) and blue forward voltage is 0.1V lower (2.9V vs 3V). Millicandela ratings remain within acceptable tolerance ranges, with green brightness slightly higher (180mcd vs 170mcd) and blue brightness marginally higher (30mcd vs 28mcd).

Both components maintain identical moisture sensitivity levels and regulatory compliance certifications, supporting direct substitution in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the CLMUD-FKA replace the CLMUC-FKA in existing PCB designs?

A: Yes. The CLMUD-FKA is a direct substitute with identical package dimensions (1.50mm × 1.50mm × 1.10mm), J-Lead configuration, and common anode setup. No PCB layout modifications are required.

Q: What are the differences in electrical characteristics between these parts?

A: Forward voltage differences are minimal. Red voltage remains at 1.9V. Green voltage is 0.2V lower (2.8V vs 3V), and blue voltage is 0.1V lower (2.9V vs 3V). These variations fall within standard LED operating tolerances and do not require circuit redesign.

Q: Are the brightness levels comparable?

A: Millicandela ratings are comparable. Red brightness is nearly identical (54mcd vs 55mcd). Green brightness is slightly higher (180mcd vs 170mcd), and blue brightness is marginally higher (30mcd vs 28mcd). These variations are within acceptable tolerance ranges for LED indication applications.

Q: Why is the CLMUC-FKA obsolete?

A: The CLMUC-FKA has reached end-of-life status. The CLMUD-FKA provides equivalent functionality with active product status and ongoing manufacturer support.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the CLMUC-FKA and CLMUD-FKA maintain REACH Unaffected status, EAR99 export classification, and identical HTSUS coding (8541.41.0000). Moisture sensitivity levels are identical at 5A (24 Hours).

Q: What is the wavelength specification for each color?

A: Both parts operate at identical wavelengths: 622nm for red, 528nm for green, and 468nm for blue. Wavelength consistency ensures color matching in multi-LED applications.

Q: Are there any supply chain advantages to using the CLMUD-FKA?

A: The CLMUD-FKA maintains active product status with documented inventory availability, providing supply chain continuity compared to the obsolete CLMUC-FKA.
