Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C503C-RCN-CYBYCAA1 is determined by the following criteria:

Primary Compatibility Parameters:

• Color specification (Red)
• Mounting type (Through Hole)
• Package configuration (Radial, 5mm form factor)
• Forward voltage range (2.1V nominal)
• Test current (20mA)
• RoHS compliance status

Identified Substitutes:

1. C503B-RCN-CW0Z0AA1 (Direct Substitute - CreeLED, Inc.): Maintains identical electrical specifications (2.1V, 20mA, 624nm dominant wavelength, 30° viewing angle) with equivalent mechanical compatibility. Differs only in millicandela rating (7500mcd vs 7350mcd) and maximum height (10.30mm vs 8.60mm). Product status is Active with higher inventory availability.

2. SLA-570LT3F (Similar Substitute - Rohm Semiconductor): Shares red color, through-hole mounting, and 5mm T-1 3/4 form factor. Operates at lower forward voltage (1.75V vs 2.1V) and reduced brightness (220mcd vs 7350mcd). Peak wavelength is 660nm. Product status is Not For New Designs. This substitute is suitable only for applications where lower brightness and different voltage characteristics are acceptable.

Parameter Comparison

Engineering Selection Recommendations

C503B-RCN-CW0Z0AA1 Selection Criteria: This part is the primary direct substitute for the C503C-RCN-CYBYCAA1. Both parts are manufactured by CreeLED, Inc., maintain Active product status, and carry RoHS compliance certification. Electrical parameters are identical (2.1V forward voltage, 20mA test current, 624nm dominant wavelength). The brightness differential (7500mcd vs 7350mcd) represents a 2% increase, which is within typical LED manufacturing tolerances. The height difference (10.30mm vs 8.60mm) must be evaluated against PCB clearance constraints. This substitute is suitable for direct replacement in new designs and production continuity scenarios.

SLA-570LT3F Selection Criteria: This part carries a "Not For New Designs" product status and is suitable only for legacy system maintenance or applications where lower brightness and reduced forward voltage are design requirements. The 220mcd output is significantly lower than the main part (97% reduction), and the 1.75V forward voltage requires circuit redesign. The 660nm peak wavelength differs from the 624nm dominant wavelength of the main part. This substitute is not recommended for new applications or direct replacement without comprehensive circuit validation.

Frequently Asked Questions (FAQ)

Q: Can C503B-RCN-CW0Z0AA1 be used as a direct replacement for C503C-RCN-CYBYCAA1?

A: Yes. Both parts share identical forward voltage (2.1V), test current (20mA), dominant wavelength (624nm), viewing angle (30°), and mounting configuration. The brightness increase (7500mcd vs 7350mcd) is within normal manufacturing variation. PCB height clearance must accommodate the 10.30mm maximum height of the C503B variant.

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

A: The SLA-570LT3F operates at 1.75V forward voltage (0.35V lower than the main part) and delivers only 220mcd brightness (97% reduction). The product carries "Not For New Designs" status. This part is suitable only for legacy applications or where reduced brightness and lower voltage operation are acceptable design parameters.

Q: Are all substitute parts RoHS compliant?

A: Yes. The main part C503C-RCN-CYBYCAA1 is RoHS Compliant. The direct substitute C503B-RCN-CW0Z0AA1 is RoHS Compliant. The similar substitute SLA-570LT3F is ROHS3 Compliant. All parts meet environmental compliance requirements.

Q: What is the primary difference between the main part and C503B-RCN-CW0Z0AA1?

A: The primary differences are millicandela rating (7500mcd vs 7350mcd) and maximum height (10.30mm vs 8.60mm). Electrical and optical specifications are equivalent. Inventory availability is significantly higher for C503B-RCN-CW0Z0AA1 (63712 pieces vs 1043 pieces).

Q: Can SLA-570LT3F be used in applications requiring 7350mcd brightness?

A: No. The SLA-570LT3F delivers 220mcd, which is insufficient for applications requiring 7350mcd brightness output. This part is not suitable for direct replacement in brightness-critical applications.
