Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C503C-ACN-CYAZA252 is determined by strict parameter matching across the following criteria:

Critical Parameters (Must Match Exactly):

• Color: Amber
• Wavelength - Dominant: 591nm
• Voltage - Forward (Vf): 2.1V
• Current - Test: 20mA
• Lens Size: 5.00mm Dia
• Lens Style: Round with Domed Top
• Lens Transparency: Clear
• Viewing Angle: 30°
• Mounting Type: Through Hole
• Height (Max): 10.10mm
• Manufacturer: CreeLED, Inc.
• RoHS Status: RoHS Compliant
• MSL Rating: 1 (Unlimited)

Variable Parameters (Allowed to Differ):

• Millicandela Rating: 7980mcd to 8930mcd
• Packaging Format: Tape & Box (TB) or Cut Tape (CT)
• Base Product Number: C503B or C503C

All four substitute parts meet these criteria and are classified as parametric equivalents suitable for direct replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts maintain Active product status and full RoHS compliance, meeting regulatory requirements equivalent to the main part. Selection between substitutes should be based on the following factors:

Packaging Consideration: The main part C503C-ACN-CYAZA252 is supplied in Tape & Box format. Substitutes C503B-ACN-CY0Z0252, C503B-ACN-CY0Z0252-030, C503B-ACN-CY0Z0342, and C503C-ACN-CYCZA342 are supplied in Cut Tape format. Packaging format compatibility with assembly equipment must be evaluated for production environments.

Brightness Specification: The main part delivers 7980mcd. Substitutes C503B-ACN-CY0Z0252, C503B-ACN-CY0Z0252-030, and C503B-ACN-CY0Z0342 deliver 8930mcd, representing a 12% increase in luminous intensity. Substitute C503C-ACN-CYCZA342 delivers 8650mcd, representing an 8% increase. Applications with brightness-sensitive specifications must account for this variation.

Inventory Availability: C503B-ACN-CY0Z0252-030 maintains the highest inventory level at 19,953 pieces, providing supply chain stability for high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can C503B-ACN-CY0Z0252 be used as a direct replacement for C503C-ACN-CYAZA252?

A: Yes. Both parts share identical electrical characteristics (2.1V forward voltage, 20mA test current, 591nm wavelength), mechanical dimensions (5mm lens diameter, 10.10mm maximum height), and optical properties (30° viewing angle, clear domed lens). The primary difference is packaging format (Cut Tape versus Tape & Box) and brightness rating (8930mcd versus 7980mcd). Circuit-level compatibility is confirmed.

Q: What is the brightness difference between the main part and substitutes?

A: The main part C503C-ACN-CYAZA252 operates at 7980mcd. Substitutes C503B-ACN-CY0Z0252, C503B-ACN-CY0Z0252-030, and C503B-ACN-CY0Z0342 operate at 8930mcd (12% higher). Substitute C503C-ACN-CYCZA342 operates at 8650mcd (8% higher). All parts maintain the same forward voltage and test current, so brightness variation results from manufacturing differences within the same product family.

Q: Are packaging format differences significant for circuit design?

A: Packaging format (Tape & Box versus Cut Tape) does not affect electrical or mechanical performance. The difference is relevant only to assembly and handling processes. Tape & Box packaging is suitable for manual or semi-automated assembly, while Cut Tape is optimized for automated pick-and-place equipment. Circuit design compatibility remains unchanged.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All parts listed are RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity rating. Regulatory compliance is equivalent across the main part and all substitutes.

Q: Which substitute should be selected for maximum inventory availability?

A: C503B-ACN-CY0Z0252-030 maintains 19,953 pieces in stock, significantly exceeding availability of other options. This part is suitable for applications where supply chain continuity is a priority.
