C503C-RCN-CYAZAAA2 Equivalent & Substitute Parts

Part Overview

The C503C-RCN-CYAZAAA2 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 30° viewing angle, suitable for discrete indicator applications requiring high luminous intensity. The part is currently in active production status with RoHS compliance and unlimited moisture sensitivity rating. Substitute parts become necessary when the primary component experiences supply constraints, inventory depletion, or when design requirements permit alternative electrical or mechanical specifications within acceptable tolerance ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C503C-RCN-CYAZAAA2 is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Color: Red (wavelength range 620-630nm for dominant wavelength)
• Mounting Type: Through Hole (radial configuration)
• Lens Size: 5mm nominal diameter
• Forward Voltage (Vf): Operating range permitting series resistor adjustment within standard circuit design tolerances
• Current Rating: 20mA test current compatibility

Mechanical Compatibility Criteria:

• Package configuration: Radial through-hole
• Lens style: Round domed top
• Height envelope: Maximum 8.60mm

Regulatory Compliance:

• RoHS compliance status
• REACH compliance status
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part SLA-570LT3F meets the core substitution criteria of red color, through-hole mounting, 5mm lens size, and radial package configuration. Variations in forward voltage (1.75V vs 2.1V), millicandela rating (220mcd vs 7980mcd), and viewing angle (25° vs 30°) require circuit-level evaluation but do not preclude substitution when design margins permit.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (C503C-RCN-CYAZAAA2): Recommended for new designs. Active production status ensures long-term availability. RoHS compliance and unlimited moisture sensitivity rating support standard manufacturing and storage conditions. High millicandela rating (7980mcd) and 30° viewing angle provide superior brightness and visibility characteristics.

Substitute Part (SLA-570LT3F): Applicable only when primary part availability is constrained. Product status designation "Not For New Designs" indicates this component is in end-of-life phase. Selection requires circuit-level analysis to accommodate lower forward voltage (1.75V vs 2.1V), significantly reduced brightness (220mcd vs 7980mcd), and narrower viewing angle (25° vs 30°). ROHS3 compliance and unlimited moisture sensitivity rating maintain regulatory alignment. Height differential (8.95mm vs 8.60mm) requires PCB layout verification.

Frequently Asked Questions (FAQ)

Q: Can SLA-570LT3F directly replace C503C-RCN-CYAZAAA2 without circuit modification?

A: Direct replacement without modification is not recommended. The 0.35V forward voltage difference (1.75V vs 2.1V) requires series resistor recalculation to maintain proper LED current. The 36x reduction in brightness (220mcd vs 7980mcd) may render the indicator insufficient for visibility-critical applications.

Q: What are the mechanical compatibility considerations?

A: Both components feature 5mm round domed-top lenses in radial through-hole packages. Height difference of 0.35mm (8.95mm vs 8.60mm) is within typical PCB clearance tolerances but requires verification in space-constrained layouts.

Q: Why is SLA-570LT3F marked "Not For New Designs"?

A: This designation indicates the component is in end-of-life status with declining manufacturer support and eventual discontinuation. New designs should prioritize C503C-RCN-CYAZAAA2 or equivalent active-status alternatives to ensure long-term supply chain stability.

Q: Are both parts RoHS compliant?

A: Yes. C503C-RCN-CYAZAAA2 carries RoHS Compliant status, while SLA-570LT3F carries ROHS3 Compliant status. Both meet current regulatory requirements for hazardous substance restrictions.

Q: What viewing angle difference exists between these parts?

A: C503C-RCN-CYAZAAA2 provides 30° viewing angle versus 25° for SLA-570LT3F. This 5° difference may impact visibility in applications requiring wide-angle indicator visibility.
