Substitute Part Grouping Explanation

Substitution eligibility for the C503C-ACS-CYCZA341 is determined by strict equivalence across the following critical parameters:

• Color and Wavelength: Amber at 591nm dominant wavelength
• Electrical Characteristics: 2.1V forward voltage and 20mA test current
• Optical Performance: 30° viewing angle with clear lens transparency
• Physical Form Factor: 5.00mm diameter round lens with domed top, through-hole radial mounting
• Compliance: RoHS Compliant status and Active product status
• Manufacturer: CreeLED, Inc.

The identified substitute parts C503B-ACS-CY0Z0251 and C503B-ACS-CY0Z0251-030 meet all critical substitution criteria. Variations in millicandela rating (8930mcd versus 8650mcd) and maximum height (12.70mm versus 12.80mm) fall within acceptable tolerance ranges for indication LED applications and do not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

All three parts—C503C-ACS-CYCZA341, C503B-ACS-CY0Z0251, and C503B-ACS-CY0Z0251-030—are Active status components manufactured by CreeLED, Inc., and carry RoHS Compliant and REACH Unaffected certifications. They are suitable for production use in regulated environments.

The substitute parts C503B-ACS-CY0Z0251 and C503B-ACS-CY0Z0251-030 are electrically and mechanically interchangeable with the primary part C503C-ACS-CYCZA341 for indication LED applications. Selection among these parts may be based on inventory availability, lead time, or supply chain considerations without compromising circuit performance or compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can C503B-ACS-CY0Z0251 be used as a direct replacement for C503C-ACS-CYCZA341?

A: Yes. Both parts share identical electrical characteristics (2.1V forward voltage, 20mA test current), optical properties (591nm amber wavelength, 30° viewing angle), and physical form factor (5mm round through-hole radial package). The millicandela rating difference (8930mcd versus 8650mcd) and maximum height difference (12.70mm versus 12.80mm) do not prevent substitution in indication applications.

Q: What is the difference between C503B-ACS-CY0Z0251 and C503B-ACS-CY0Z0251-030?

A: Both parts are parametrically identical. The suffix "-030" in C503B-ACS-CY0Z0251-030 represents a packaging or distribution variant. Electrical and mechanical specifications are equivalent.

Q: Are all three parts RoHS Compliant?

A: Yes. C503C-ACS-CYCZA341, C503B-ACS-CY0Z0251, and C503B-ACS-CY0Z0251-030 are all RoHS Compliant and REACH Unaffected, meeting regulatory requirements for current production.

Q: Will the height difference affect PCB layout?

A: The maximum height difference is 0.10mm (12.80mm versus 12.70mm). This tolerance is negligible for through-hole LED applications and does not require PCB redesign.

Q: Can these parts be mixed in the same production run?

A: Yes. All three parts meet identical electrical and optical specifications for indication LED function and are suitable for use in the same circuit design.
