C503C-RCN-CYAZAAA1 Equivalent & Substitute Parts

Part Overview

The C503C-RCN-CYAZAAA1 is a red LED indication component manufactured by CreeLED, Inc., designed for through-hole mounting applications. This 5mm round LED operates at 2.1V forward voltage with a 7980mcd brightness rating and 624nm dominant wavelength. The component is currently in active production status and fully RoHS compliant.

Substitute parts become necessary when the primary component experiences supply constraints, inventory depletion, or when design requirements permit alternative specifications within acceptable electrical and mechanical tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C503C-RCN-CYAZAAA1 is determined by the following critical parameters:

• Color specification (Red)
• Mounting type (Through Hole)
• Lens size category (5mm form factor)
• Package configuration (Radial)
• Electrical operating range (forward voltage and test current compatibility)
• Mechanical envelope (height and physical dimensions)
• Wavelength compatibility within red spectrum range

The identified substitute SLA-570LT3F from Rohm Semiconductor meets the core mechanical and electrical compatibility criteria for this product category, though with variations in specific performance metrics.

Engineering Selection Recommendations

The C503C-RCN-CYAZAAA1 is the preferred component for new designs due to its active production status and current RoHS compliance certification. The SLA-570LT3F substitute is classified as "Not For New Designs" and should be considered only for legacy system maintenance or when the primary component is unavailable.

Key selection considerations based on provided specifications:

• Forward voltage differential (2.1V vs 1.75V) requires circuit design verification for brightness and power consumption impact
• Brightness variance (7980mcd vs 220mcd) represents a significant performance difference and must be evaluated against application requirements
• Both components maintain RoHS compliance and REACH unaffected status
• Mechanical compatibility is acceptable within the specified height tolerances (8.60mm vs 8.95mm)

Frequently Asked Questions (FAQ)

Q: Can the SLA-570LT3F directly replace the C503C-RCN-CYAZAAA1 in existing designs?

A: Direct replacement requires circuit-level verification. The 0.35V forward voltage reduction and 7760mcd brightness difference necessitate evaluation of current-limiting resistor values and optical output requirements.

Q: What are the primary differences between these components?

A: The main differences are forward voltage (2.1V vs 1.75V), brightness rating (7980mcd vs 220mcd), and product status (Active vs Not For New Designs). Both share identical mounting type, lens size category, and radial package configuration.

Q: Are both components RoHS compliant?

A: Yes. The C503C-RCN-CYAZAAA1 is RoHS Compliant, and the SLA-570LT3F is ROHS3 Compliant. Both meet current environmental compliance requirements.

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates the SLA-570LT3F is in mature or declining production phase. It should not be selected for new product development; use only for legacy system support or temporary supply solutions.

Q: Do the wavelength specifications differ significantly?

A: The C503C-RCN-CYAZAAA1 specifies 624nm dominant wavelength, while the SLA-570LT3F specifies 660nm peak wavelength. Both fall within the red spectrum range but represent different color coordinates within the red classification.

Q: Are the mechanical dimensions compatible with existing PCB layouts?

A: Both components use 5mm through-hole radial packages with acceptable height variance (8.60mm vs 8.95mm maximum). Standard PCB footprints designed for 5mm round LEDs accommodate both components.
