Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C503C-ACS-CYAZA251 is determined by strict equivalence across the following critical parameters:

• Color: Amber
• Lens size and style: 5.00mm diameter, round with domed top, clear
• Electrical characteristics: 2.1V forward voltage, 20mA test current, 30° viewing angle
• Mounting configuration: Through-hole radial package
• Wavelength specification: 591nm dominant wavelength
• Regulatory compliance: RoHS compliant, REACH unaffected

The substitute parts C503B-ACS-CY0Z0251 and C503B-ACS-CY0Z0251-030 meet all critical substitution criteria. Variations in millicandela rating and maximum height fall within acceptable tolerance ranges for this product category and do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with identical RoHS and REACH compliance certifications. The C503B variants offer higher millicandela ratings (8930mcd versus 7980mcd) while maintaining identical electrical specifications and mechanical form factors. Height variation between the main part (12.80mm maximum) and substitute parts (12.70mm maximum) is within standard manufacturing tolerance and does not affect PCB layout or assembly compatibility for through-hole applications.

Selection between C503B-ACS-CY0Z0251 and C503B-ACS-CY0Z0251-030 is determined by inventory availability and supply chain requirements, as both parts are electrically and mechanically identical.

Frequently Asked Questions (FAQ)

Q: Can C503B-ACS-CY0Z0251 be used as a direct replacement for C503C-ACS-CYAZA251?

A: Yes. Both parts share identical electrical characteristics (2.1V forward voltage, 20mA test current), optical properties (591nm wavelength, 30° viewing angle), and mechanical specifications (5mm round through-hole package). The higher millicandela rating of the C503B variant does not affect compatibility.

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

A: These parts are electrically and mechanically identical. Both feature 8930mcd brightness and 12.70mm maximum height. Selection is based on inventory availability and supply chain logistics.

Q: Does the 0.10mm height difference between the main part and substitutes affect PCB assembly?

A: No. The 0.10mm variation (12.80mm versus 12.70mm) is within standard manufacturing tolerance for through-hole components and does not impact PCB layout, soldering, or mechanical clearance.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. The C503C-ACS-CYAZA251 and both C503B variants are RoHS compliant and REACH unaffected, meeting identical regulatory requirements.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. All three parts maintain identical forward voltage, test current, viewing angle, wavelength, and through-hole radial package configuration, enabling direct substitution without circuit redesign.
