Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the C503C-RCS-CYBYCAA2 are classified based on the following substitution criteria:

Direct Manufacturer Substitutes maintain identical electrical performance and mechanical compatibility:

• Same color (Red) and dominant wavelength (624nm)
• Identical forward voltage (2.1V) and test current (20mA)
• Same lens size (5.00mm) and mounting type (Through Hole)
• Equivalent viewing angle (30°)
• Variation in packaging format (Cut Tape vs. Tape & Box)
• Minor brightness variation within acceptable tolerance (7350-7500mcd range)

Parametric Equivalents provide functional compatibility with minor parameter deviations:

• Same electrical characteristics and mechanical form factor
• Brightness within acceptable range for indication applications
• Height variation within component tolerance

Similar Parts offer functional substitution with notable parameter differences:

• Different manufacturer (Rohm Semiconductor vs. CreeLED)
• Lower brightness rating (220mcd vs. 7350mcd)
• Different forward voltage (1.75V vs. 2.1V)
• Narrower viewing angle (25° vs. 30°)
• Different product status (Not For New Designs)
• Suitable only when application requirements permit lower brightness and different electrical characteristics

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (C503B-RCN-CW0Z0AA2 or C503B-RCS-CW0Z0AA2):

Both C503B variants are suitable direct replacements when packaging format flexibility is acceptable. These parts maintain identical electrical specifications (2.1V, 20mA test current) and equivalent brightness performance (7500mcd). The primary differences are packaging format (Cut Tape vs. Tape & Box) and physical height variation (10.30mm to 12.90mm). Both parts are Active status products with RoHS compliance. Selection between these two should be based on available inventory and packaging requirements for assembly processes.

For Parametric Equivalent Selection (C503B-RCS-CW0Z0AA2):

This part provides full functional compatibility with identical electrical characteristics and brightness within acceptable tolerance. Height specification (12.90mm) closely matches the original part (12.60mm). This option is recommended when Cut Tape packaging is preferred and inventory availability is a consideration (1227 units in stock).

For Similar Part Selection (SLA-570LT3F):

The SLA-570LT3F from Rohm Semiconductor is classified as a similar part due to significant parameter deviations. This part operates at 1.75V forward voltage (vs. 2.1V) and provides substantially lower brightness (220mcd vs. 7350mcd). The viewing angle is narrower (25° vs. 30°). Additionally, this part carries a "Not For New Designs" product status. Selection of this part is appropriate only when application requirements explicitly permit lower brightness output and different electrical characteristics. Circuit design modifications may be necessary to accommodate the lower forward voltage.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical electrical specifications (2.1V forward voltage, 20mA test current, 624nm dominant wavelength) and equivalent brightness ratings (7500mcd vs. 7350mcd). The primary difference is packaging format (Cut Tape vs. Tape & Box). Physical height differs by 2.3mm (10.30mm vs. 12.60mm), which may require verification against PCB layout constraints.

Q: What is the difference between C503B-RCN-CW0Z0AA2 and C503B-RCS-CW0Z0AA2?

A: Both parts are CreeLED C503B variants with identical electrical performance. The difference is packaging format (Cut Tape for both) and physical height (10.30mm vs. 12.90mm). Brightness is equivalent at 7500mcd. Selection depends on assembly process requirements and available inventory.

Q: Is SLA-570LT3F a suitable replacement?

A: SLA-570LT3F is a similar part with significant parameter differences. Forward voltage is lower (1.75V vs. 2.1V), brightness is substantially lower (220mcd vs. 7350mcd), and viewing angle is narrower (25° vs. 30°). This part is suitable only when application requirements explicitly permit these deviations. Additionally, this part is marked "Not For New Designs," limiting its use in new product development.

Q: What parameters must remain constant for substitution?

A: For direct substitution, the following parameters must remain constant: color (Red), lens size (5.00mm), mounting type (Through Hole), and forward voltage (2.1V). Brightness variation within the 7350-7500mcd range is acceptable for indication applications. Physical height variation should be verified against PCB layout constraints.

Q: Are all substitute parts RoHS compliant?

A: Yes. C503C-RCS-CYBYCAA2, C503B-RCN-CW0Z0AA2, and C503B-RCS-CW0Z0AA2 are all RoHS Compliant. SLA-570LT3F is ROHS3 Compliant. All parts meet applicable RoHS requirements.

Q: What is the inventory status of substitute parts?

A: C503B-RCN-CW0Z0AA2 has 54964 units in stock. C503B-RCS-CW0Z0AA2 has 1227 units in stock. SLA-570LT3F has 941 units in stock. The original C503C-RCS-CYBYCAA2 has 988 units in stock.
