C503C-ACN-CYAZA342 Equivalent & Substitute Parts

Part Overview

The C503C-ACN-CYAZA342 is an amber 5mm through-hole LED manufactured by CreeLED, Inc., designed for indication applications. This part operates at 2.1V forward voltage with a 591nm dominant wavelength and delivers 7980mcd at 20mA test current. The product is Active status and RoHS Compliant, suitable for standard discrete LED circuit implementations. Substitute parts are identified to address packaging availability, inventory levels, and minor luminous intensity variations within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C503C-ACN-CYAZA342 is determined by the following critical parameters:

• Color and Wavelength: All substitutes must be amber with 591nm dominant wavelength
• Electrical Characteristics: Forward voltage (Vf) of 2.1V and test current of 20mA are mandatory
• Mechanical Compatibility: 5mm diameter round lens with domed top, through-hole mounting, and maximum height of 10.10mm
• Viewing Angle: 30° viewing angle maintained across all substitutes
• Compliance: RoHS Compliant status and MSL 1 (Unlimited) moisture sensitivity level

The identified substitute parts vary in packaging format (Cut Tape vs. Tape & Box) and luminous intensity (millicandela rating between 8650mcd and 8930mcd), which fall within acceptable tolerance ranges for amber LED indication applications. All substitutes share the same base electrical and mechanical specifications as the primary part.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and RoHS Compliance, ensuring regulatory alignment with the primary C503C-ACN-CYAZA342 part. Selection between substitutes should be based on packaging requirements and inventory availability:

• C503B-ACN-CY0Z0252-030: Highest inventory availability (19,953 pcs) with Cut Tape packaging and 8930mcd luminous intensity
• C503B-ACN-CY0Z0252: Cut Tape packaging with 8930mcd luminous intensity and 843 pcs inventory
• C503B-ACN-CY0Z0342: Cut Tape packaging with 8930mcd luminous intensity and 3,600 pcs inventory
• C503C-ACN-CYCZA342: Cut Tape packaging with 8650mcd luminous intensity and 3,566 pcs inventory, closest to original part's millicandela rating

All substitutes are electrically and mechanically interchangeable with the primary part within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can C503B series parts substitute for C503C series parts? A: Yes. Both series share identical electrical characteristics (2.1V Vf, 20mA test current), mechanical dimensions (5mm diameter, 10.10mm max height), and optical properties (591nm wavelength, 30° viewing angle). The primary difference is packaging format and millicandela rating variation.

Q: What is the difference between Tape & Box (TB) and Cut Tape (CT) packaging? A: Tape & Box packaging includes a protective box for bulk quantities, while Cut Tape is supplied in individual tape segments. Both formats contain the same component and are suitable for through-hole assembly. Selection depends on handling, storage, and assembly line requirements.

Q: Are there luminous intensity differences between substitutes? A: Yes. The primary part C503C-ACN-CYAZA342 delivers 7980mcd, while most substitutes deliver 8930mcd. The C503C-ACN-CYCZA342 substitute delivers 8650mcd. These variations remain within acceptable tolerance for amber LED indication circuits and do not affect electrical compatibility.

Q: Do all substitutes meet the same compliance standards? A: Yes. All parts are RoHS Compliant, REACH Unaffected, and classified as MSL 1 (Unlimited) moisture sensitivity level. ECCN and HTSUS classifications are identical across all parts.

Q: Which substitute offers the best inventory availability? A: C503B-ACN-CY0Z0252-030 provides the highest stock level at 19,953 pcs, making it the optimal choice for high-volume applications requiring immediate availability.
