C503C-RCS-CYAZAAA1 Equivalent & Substitute Parts

Part Overview

The C503C-RCS-CYAZAAA1 is a red LED indication component manufactured by CreeLED, Inc., designed for through-hole mounting applications. This discrete 5mm round LED operates at 2.1V forward voltage with a dominant wavelength of 624nm and delivers 7980mcd brightness. The component is actively produced and RoHS compliant, making it suitable for new designs requiring high-brightness red indication in standard through-hole configurations.

Substitute parts become necessary when the primary component experiences supply constraints, inventory limitations, or when design requirements permit alternative optical or electrical characteristics within acceptable tolerance ranges.

Key Parameters

Substitute Part Grouping Explanation

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

• Color: Red wavelength indication (dominant wavelength 624nm or peak wavelength 660nm acceptable)
• Lens Size: 5mm diameter through-hole package
• Mounting Type: Through-hole radial configuration
• Voltage Range: Forward voltage tolerance for 20mA test current
• Brightness: Millicandela rating sufficient for indication applications
• Compliance: RoHS and REACH compliance status
• Product Status: Active or legacy status affecting design applicability

The substitute part SLA-570LT3F meets the core substitution criteria of red color, 5mm lens size, through-hole mounting, and radial package configuration. Electrical and optical characteristics differ within acceptable ranges for indication applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Component (C503C-RCS-CYAZAAA1): Select for new designs requiring active product status, high brightness output (7980mcd), and CreeLED manufacturing. This component maintains full RoHS compliance and unlimited moisture sensitivity rating.

Substitute Component (SLA-570LT3F): This part is designated "Not For New Designs" by the manufacturer. Selection is limited to legacy system maintenance, retrofit applications, or situations where supply of the primary component is unavailable. The substitute exhibits lower brightness (220mcd) and reduced forward voltage (1.75V), requiring circuit design verification. ROHS3 compliance and radial through-hole package maintain mechanical and regulatory compatibility.

Both components carry REACH Unaffected status and EAR99 classification, with identical HTSUS coding (8541.41.0000).

Frequently Asked Questions (FAQ)

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

A: Mechanical compatibility is confirmed through matching 5mm lens diameter and radial through-hole package. Electrical compatibility requires verification: the substitute operates at 1.75V forward voltage versus 2.1V, and delivers 220mcd versus 7980mcd brightness. Circuit designs dependent on specific brightness levels or voltage characteristics must be evaluated.

Q: What are the key differences between these parts?

A: The primary differences are brightness (7980mcd vs. 220mcd), forward voltage (2.1V vs. 1.75V), and product status (Active vs. Not For New Designs). Both maintain 5mm through-hole radial packages, red color indication, and 20mA test current specifications.

Q: Is the substitute part suitable for new product development?

A: No. The SLA-570LT3F carries "Not For New Designs" status, indicating the manufacturer has discontinued active support. New designs should utilize the C503C-RCS-CYAZAAA1 or identify alternative active-status components.

Q: Are there compliance concerns with substitution?

A: Both components maintain RoHS compliance (RoHS vs. ROHS3), REACH Unaffected status, and identical tariff classification. No compliance barriers exist for substitution in regulated applications.

Q: How do viewing angles compare?

A: The primary component provides 30° viewing angle versus 25° for the substitute. Applications requiring wider light distribution should account for this 5° reduction in the substitute part.
