C503C-RCN-CYCZAAA1 Equivalent & Substitute Parts

Part Overview

The C503C-RCN-CYCZAAA1 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 624nm dominant wavelength and delivers 8650mcd brightness. The component is classified as Active product status and is RoHS Compliant. Substitute parts become necessary when the primary component reaches end-of-life inventory, when design flexibility is required across manufacturing batches, or when alternative suppliers offer equivalent electrical and mechanical performance within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C503C-RCN-CYCZAAA1 is determined by the following critical parameters:

• Color: Red LED indication
• Mounting Type: Through Hole radial configuration
• Lens Size: 5mm form factor
• Test Current: 20mA operating condition
• Wavelength Range: Red spectrum (620–660nm acceptable)
• Forward Voltage: 1.75V–2.1V range
• Brightness: Millicandela rating within functional tolerance
• Compliance: RoHS and REACH status alignment
• Package Configuration: Radial through-hole package

The substitute part SLA-570LT3F meets these criteria with compatible electrical characteristics and identical mounting methodology, though with differing brightness and wavelength specifications within the red LED category.

Parameter Comparison

Engineering Selection Recommendations

Primary Component (C503C-RCN-CYCZAAA1): Recommended for new designs. Active product status ensures ongoing manufacturer support and supply chain availability. RoHS Compliant certification meets environmental regulatory requirements. The higher millicandela rating (8650mcd) provides superior brightness for indication applications requiring high visibility.

Substitute Component (SLA-570LT3F): Acceptable for legacy design maintenance or applications where brightness reduction is tolerable. Product status "Not For New Designs" indicates this component is in end-of-life phase; use only when primary component is unavailable. ROHS3 Compliant status maintains environmental compliance. Forward voltage differential (1.75V vs. 2.1V) requires circuit verification to ensure proper LED current limiting and brightness performance.

Selection between these components must account for circuit design constraints, brightness requirements, and supply chain considerations. The substitute part's significantly lower millicandela rating (220mcd vs. 8650mcd) represents a material functional difference requiring application-level assessment.

Frequently Asked Questions (FAQ)

Q: Can SLA-570LT3F directly replace C503C-RCN-CYCZAAA1 in existing circuits?

A: Direct replacement requires circuit verification. The 0.35V forward voltage difference (1.75V vs. 2.1V) affects LED current and brightness. Current-limiting resistor values may require adjustment to maintain proper LED operation and achieve acceptable brightness levels.

Q: What is the brightness difference between these components?

A: C503C-RCN-CYCZAAA1 delivers 8650mcd while SLA-570LT3F delivers 220mcd at 20mA test current. This 39:1 brightness ratio represents a significant functional difference. Applications requiring high-visibility indication should retain the primary component.

Q: Are both components suitable for new product designs?

A: C503C-RCN-CYCZAAA1 is recommended for new designs (Active status). SLA-570LT3F carries "Not For New Designs" status and should be used only for legacy product support or when the primary component is unavailable.

Q: Do these components share identical package dimensions?

A: Both use 5mm through-hole radial packages with similar form factors. Height specifications differ slightly (8.60mm vs. 8.95mm maximum), which is negligible for most PCB layouts. Viewing angles differ marginally (30° vs. 25°), with the primary component offering slightly wider light distribution.

Q: What compliance certifications apply to both components?

A: Both components are RoHS Compliant (C503C-RCN-CYCZAAA1: RoHS Compliant; SLA-570LT3F: ROHS3 Compliant) and REACH Unaffected. Both meet environmental regulatory requirements for electronic component manufacturing and use.
