C503C-RCN-CYCZAAA2 Equivalent & Substitute Parts

Part Overview

The C503C-RCN-CYCZAAA2 is a red LED indication component manufactured by CreeLED, Inc., designed for through-hole mounting applications. This 5mm round LED with clear domed lens operates at 2.1V forward voltage and delivers 8650mcd luminous intensity at 20mA test current. The component is classified as Active product status and is RoHS Compliant with unlimited moisture sensitivity rating.

Substitute parts become necessary when the primary component experiences supply constraints, inventory limitations, 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-CYCZAAA2 is determined by the following critical parameters:

• Color: Red
• Mounting Type: Through Hole
• Lens Size: 5mm form factor
• Wavelength Range: Red spectrum (620-660nm)
• Forward Voltage: Acceptable range for red LEDs (1.75V to 2.1V)
• Current Rating: 20mA test current compatibility
• Package Configuration: Radial through-hole

The identified substitute SLA-570LT3F from Rohm Semiconductor meets the core functional requirements within these parameters, though with variations in specific electrical characteristics and product lifecycle status.

Engineering Selection Recommendations

The C503C-RCN-CYCZAAA2 maintains Active product status with full RoHS compliance, making it the preferred selection for new designs and long-term production applications. This component is recommended for applications requiring sustained supply availability and compliance with current regulatory standards.

The SLA-570LT3F substitute is classified as Not For New Designs, indicating it is suitable only for legacy system maintenance, repair, or replacement scenarios where the original component is unavailable. While this substitute maintains ROHS3 compliance and identical moisture sensitivity rating, its Not For New Designs status restricts its application to existing product support only.

Selection between these components should be based on product lifecycle requirements: Active status components for new development, and Not For New Designs components exclusively for sustaining engineering and field replacement purposes.

Frequently Asked Questions (FAQ)

Q: Can the SLA-570LT3F be used as a direct replacement in new designs?

A: No. The SLA-570LT3F carries Not For New Designs status and is restricted to legacy system support and field replacement only. The C503C-RCN-CYCZAAA2 is the appropriate selection for new product development.

Q: What are the key electrical differences between these components?

A: The main differences are forward voltage (2.1V vs 1.75V), luminous intensity (8650mcd vs 220mcd), and viewing angle (30° vs 25°). These variations require circuit design verification before substitution.

Q: Are both components mechanically compatible?

A: Both components use 5mm round through-hole radial packages with domed tops. Maximum heights differ slightly (8.60mm vs 8.95mm), which may affect PCB layout in space-constrained applications.

Q: Do both components meet current compliance requirements?

A: The C503C-RCN-CYCZAAA2 is RoHS Compliant. The SLA-570LT3F is ROHS3 Compliant. Both are REACH Unaffected with unlimited moisture sensitivity rating (MSL 1).

Q: What wavelength specifications apply to each component?

A: The C503C-RCN-CYCZAAA2 specifies dominant wavelength at 624nm. The SLA-570LT3F specifies peak wavelength at 660nm. Both fall within the red spectrum range for indication applications.
