Substitute Part Grouping Explanation
Substitute parts for the C503C-RCS-CYBYCAA1 are classified into two categories based on parametric alignment:
Direct Manufacturer Substitutes (CreeLED, Inc.): Parts C503B-RCN-CW0Z0AA1 and C503B-RCS-CW0Z0AA1 maintain identical electrical specifications (2.1V forward voltage, 20mA test current, 624nm dominant wavelength, 30° viewing angle) and mechanical compatibility (5mm round through-hole radial package). These parts differ only in millicandela rating (7500mcd vs. 7350mcd) and physical height, representing direct functional equivalents within the same product family.
Similar Substitute (Cross-Manufacturer): Part SLA-570LT3F from Rohm Semiconductor provides alternative red LED indication capability in a 5mm through-hole package. This part operates at different electrical parameters (1.75V forward voltage, 220mcd brightness, 25° viewing angle, 660nm peak wavelength) and is classified as Not For New Designs, making it suitable only for legacy system maintenance or specific low-brightness applications.
Substitution eligibility is determined by: color match (red), lens size (5mm), mounting type (through-hole radial), and compliance status (RoHS/REACH).

Engineering Selection Recommendations
For New Designs: Select C503B-RCN-CW0Z0AA1 or C503B-RCS-CW0Z0AA1 as primary substitutes. Both parts are Active products from CreeLED, Inc., with identical electrical specifications (2.1V, 20mA, 624nm) and full RoHS/REACH compliance. The choice between these two depends on physical height constraints: C503B-RCN-CW0Z0AA1 at 10.30mm maximum height or C503B-RCS-CW0Z0AA1 at 12.90mm maximum height.
For Legacy System Maintenance: SLA-570LT3F from Rohm Semiconductor is available as a substitute only for systems designed to accommodate its different electrical parameters (1.75V forward voltage, 220mcd brightness, 25° viewing angle). This part carries Not For New Designs status and should not be selected for new applications.
Compliance Considerations: All substitute parts maintain RoHS and REACH compliance equivalent to the main part, ensuring regulatory continuity across component selection.
Frequently Asked Questions (FAQ)
Q: Can C503B-RCN-CW0Z0AA1 and C503B-RCS-CW0Z0AA1 be used interchangeably with C503C-RCS-CYBYCAA1?
A: Yes, both parts are direct functional equivalents. They share identical forward voltage (2.1V), test current (20mA), dominant wavelength (624nm), viewing angle (30°), and 5mm through-hole radial package configuration. The primary differences are millicandela rating (7500mcd vs. 7350mcd) and physical height. Verify that your PCB layout accommodates the specified maximum height of each part.
Q: What are the key differences between the CreeLED substitutes and the Rohm SLA-570LT3F?
A: The Rohm SLA-570LT3F operates at 1.75V forward voltage (versus 2.1V for CreeLED parts), produces 220mcd brightness (versus 7350–7500mcd), and has a 25° viewing angle (versus 30°). The SLA-570LT3F is marked Not For New Designs and should be used only for legacy system support where these electrical parameters are already established in the design.
Q: Are there any height restrictions I should consider when selecting a substitute?
A: Yes. The C503C-RCS-CYBYCAA1 has a maximum height of 12.60mm. The C503B-RCN-CW0Z0AA1 is shorter at 10.30mm, while the C503B-RCS-CW0Z0AA1 is slightly taller at 12.90mm. Verify your PCB clearance and component placement requirements before selection.
Q: Do all substitute parts meet the same compliance standards?
A: Yes. All substitute parts are RoHS Compliant and REACH Unaffected, matching the compliance profile of the main part C503C-RCS-CYBYCAA1.
Q: Which substitute should I choose for a new design?
A: For new designs, select either C503B-RCN-CW0Z0AA1 or C503B-RCS-CW0Z0AA1 based on your physical height constraints. Both are Active products with identical electrical specifications. Do not select SLA-570LT3F for new designs due to its Not For New Designs status.
