C503C-RCN-CYBYCAA2 Equivalent & Substitute Parts

Part Overview

The C503C-RCN-CYBYCAA2 is a red 5mm through-hole LED manufactured by CreeLED, Inc., designed for indication applications. This part operates at 2.1V forward voltage with a 7350mcd brightness rating and 624nm dominant wavelength. The product is currently Active and RoHS Compliant, making it suitable for new designs.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the allowed parameter tolerances for this LED category. Alternatives may be required due to inventory availability, packaging format preferences, or specific application constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the C503C-RCN-CYBYCAA2 are classified based on the following electrical and mechanical compatibility criteria:

Direct Substitutes maintain identical or near-identical electrical characteristics: red color, 2.1V forward voltage, 20mA test current, 5mm lens diameter, through-hole mounting, and round domed lens style. Brightness (millicandela) and viewing angle variations within ±10% are acceptable for indication applications.

Similar Substitutes share the same color, mounting type, and lens size but may deviate in forward voltage, brightness, or wavelength specifications. These parts are suitable only when circuit design accommodates the electrical differences and application requirements permit reduced brightness or altered viewing characteristics.

Parameter Comparison

Engineering Selection Recommendations

C503B-RCN-CW0Z0AA2 is the primary direct substitute for C503C-RCN-CYBYCAA2. Both parts are manufactured by CreeLED, Inc., share identical electrical specifications (2.1V forward voltage, 20mA test current, 624nm dominant wavelength), and maintain compatible mechanical form factors. The brightness difference (7500mcd vs. 7350mcd) represents a 2% increase, which is negligible for indication applications. The height difference (10.30mm vs. 8.60mm) must be verified against PCB clearance constraints. Both parts are Active products with RoHS Compliance, suitable for new designs. The primary distinction is packaging format: C503B-RCN-CW0Z0AA2 is supplied in Cut Tape, while C503C-RCN-CYBYCAA2 is supplied in Tape & Box.

SLA-570LT3F is a similar substitute manufactured by Rohm Semiconductor. This part shares the same color, mounting type, and lens size but operates at a lower forward voltage (1.75V vs. 2.1V) and significantly reduced brightness (220mcd vs. 7350mcd). The product status is "Not For New Designs," which restricts its use to legacy applications or maintenance scenarios only. Circuit redesign is required to accommodate the 0.35V voltage difference. This part is suitable only when brightness reduction is acceptable and forward voltage adjustment is feasible.

Frequently Asked Questions (FAQ)

Q: Can C503B-RCN-CW0Z0AA2 be used as a direct replacement for C503C-RCN-CYBYCAA2?

A: Yes. Both parts are electrically identical (2.1V, 20mA, 624nm) and mechanically compatible (5mm round domed lens, through-hole mounting). The brightness difference (7500mcd vs. 7350mcd) is within acceptable tolerance for indication applications. Verify PCB clearance for the 1.7mm height difference.

Q: What are the limitations of SLA-570LT3F as a substitute?

A: SLA-570LT3F operates at 1.75V forward voltage (0.35V lower) and provides only 220mcd brightness (97% reduction). Circuit modification is required to accommodate the voltage difference. The product status "Not For New Designs" restricts use to legacy or maintenance applications only.

Q: How do packaging formats affect substitution?

A: C503C-RCN-CYBYCAA2 is supplied in Tape & Box format, while C503B-RCN-CW0Z0AA2 is supplied in Cut Tape, and SLA-570LT3F is supplied in Bulk. Packaging affects handling, storage, and assembly processes but does not impact electrical or mechanical compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. C503C-RCN-CYBYCAA2 and C503B-RCN-CW0Z0AA2 are RoHS Compliant. SLA-570LT3F is ROHS3 Compliant. All parts meet regulatory requirements for restricted substance elimination.

Q: What is the significance of "Not For New Designs" status for SLA-570LT3F?

A: This designation indicates the part is in end-of-life phase and should not be selected for new product development. Use is restricted to replacement or maintenance of existing systems only.
