Substitute Part Grouping Explanation

Substitution eligibility for the C503C-ACS-CYAZA342 is determined by strict equivalence in the following critical parameters:

• Color: Amber
• Dominant Wavelength: 591nm
• Lens Size: 5.00mm Dia
• Lens Style: Round with Domed Top
• Lens Transparency: Clear
• Forward Voltage (Vf): 2.1V
• Test Current: 20mA
• Viewing Angle: 30°
• Mounting Type: Through Hole
• Package / Case: Radial
• RoHS Compliance: RoHS Compliant
• MSL Rating: 1 (Unlimited)

The identified substitute parts C503B-ACS-CX0Z0252 and C503B-ACS-CY0Z0252-030 meet all critical electrical and mechanical parameters. Variations in millicandela rating and packaging format (Cut Tape vs. Tape & Box) do not affect functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts are manufactured by CreeLED, Inc., carry Active product status, and maintain full RoHS and REACH compliance. The C503C-ACS-CYAZA342 is supplied in Tape & Box packaging, while both substitute parts are supplied in Cut Tape format. Selection between C503B-ACS-CX0Z0252 and C503B-ACS-CY0Z0252-030 depends on brightness requirements within the specified operating parameters, as both maintain identical electrical characteristics and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can C503B-ACS-CX0Z0252 or C503B-ACS-CY0Z0252-030 be used as direct replacements for C503C-ACS-CYAZA342?

A: Yes. Both substitute parts meet all critical electrical and mechanical parameters: identical forward voltage (2.1V), test current (20mA), viewing angle (30°), dominant wavelength (591nm), lens size (5.00mm), and mounting type (through-hole radial). Packaging format differences do not affect circuit functionality.

Q: What is the difference between the two substitute parts?

A: C503B-ACS-CX0Z0252 and C503B-ACS-CY0Z0252-030 differ only in millicandela rating (8090mcd vs. 8930mcd) and are both supplied in Cut Tape packaging. Both maintain identical electrical specifications and are functionally interchangeable.

Q: Does the packaging format change affect compatibility?

A: No. The original part uses Tape & Box (TB) packaging while substitutes use Cut Tape (CT) packaging. This affects handling and storage logistics only, not electrical or mechanical compatibility in circuit applications.

Q: Are all parts RoHS and REACH compliant?

A: Yes. The C503C-ACS-CYAZA342 and both substitute parts are RoHS Compliant and REACH Unaffected, meeting regulatory requirements for electronic component use.

Q: What is the maximum height difference between parts?

A: The C503C-ACS-CYAZA342 has a maximum height of 12.80mm, while both substitute parts have a maximum height of 12.70mm. This 0.10mm difference is within standard mechanical tolerances for through-hole PCB applications.
