Substitute Part Grouping Explanation

Substitute parts C503B-ACS-CY0Z0251 and C503B-ACS-CY0Z0251-030 are classified as parametric equivalents to C503C-ACS-CYAZA341 based on the following criteria:

• Identical color specification (Amber)
• Identical dominant wavelength (591nm)
• Identical forward voltage (2.1V)
• Identical test current (20mA)
• Identical lens size (5.00mm Dia)
• Identical lens style (Round with Domed Top)
• Identical lens transparency (Clear)
• Identical viewing angle (30°)
• Identical mounting type (Through Hole)
• Identical package configuration (Radial, 5mm Round)
• Identical RoHS compliance status

Variations in millicandela rating and maximum height do not preclude substitution when electrical and optical characteristics remain within specification.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with RoHS compliance and REACH unaffected designation. Selection between C503C-ACS-CYAZA341 and its substitutes C503B-ACS-CY0Z0251 or C503B-ACS-CY0Z0251-030 is determined by:

• Inventory availability and lead time requirements
• PCB layout constraints related to maximum height tolerance (0.10mm difference between C503C and C503B variants)
• Brightness requirements, noting that C503B variants provide 8930mcd versus 7980mcd for C503C
• Compliance certifications remain consistent across all three parts

Frequently Asked Questions (FAQ)

Q: Can C503B-ACS-CY0Z0251 directly replace C503C-ACS-CYAZA341 in existing designs?

A: Yes. Both parts share identical electrical specifications (2.1V forward voltage, 20mA test current), optical characteristics (591nm dominant wavelength, 30° viewing angle), and mechanical form factor (5mm round through-hole radial package). The 0.10mm height difference is negligible for standard PCB applications.

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

A: Both variants are electrically and optically identical with matching millicandela ratings (8930mcd) and maximum heights (12.70mm). The suffix designation indicates a manufacturing or packaging variant. Selection depends on supplier availability and internal part numbering systems.

Q: Does the higher millicandela rating of C503B variants affect circuit design?

A: No. The millicandela rating reflects luminous intensity at specified test conditions but does not alter the electrical operating parameters. Forward voltage and test current remain constant at 2.1V and 20mA respectively. Circuit design remains unchanged.

Q: Are all three parts suitable for RoHS-regulated applications?

A: Yes. C503C-ACS-CYAZA341, C503B-ACS-CY0Z0251, and C503B-ACS-CY0Z0251-030 are all RoHS compliant and REACH unaffected, meeting regulatory requirements for restricted substance use.

Q: Can these parts be used interchangeably in high-volume production?

A: Yes, provided PCB layout accommodates the maximum height specification of 12.70mm to 12.80mm. All parts are manufactured by CreeLED, Inc., with identical mounting type (through-hole radial) and package configuration (5mm round).
