C503C-ACN-CYAZA251 Equivalent & Substitute Parts

Part Overview

The C503C-ACN-CYAZA251 is an amber LED indicator with 5mm round through-hole packaging, manufactured by CreeLED, Inc. This discrete component operates at 2.1V forward voltage with a dominant wavelength of 591nm and delivers 7980mcd at 20mA test current. The product is Active status and RoHS Compliant, making it suitable for standard indication applications requiring amber light output.

Substitute parts are identified when design requirements allow flexibility in brightness output or wavelength tolerance within the amber spectrum, while maintaining identical electrical characteristics, mechanical form factor, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts are Active status products from CreeLED, Inc., with RoHS Compliance and MSL Level 1 certification. Selection between the main part and substitutes depends on brightness requirements:

• C503C-ACN-CYAZA251: 7980mcd at 591nm wavelength. Use when baseline brightness specification is required.
• C503B-ACN-CY0Z0341-030: 8930mcd at 590nm wavelength. Higher brightness output with wavelength at lower amber spectrum boundary. Suitable when increased luminous intensity is acceptable.
• C503C-ACN-CYCZA251: 8650mcd at 591nm wavelength. Intermediate brightness with matching wavelength to main part. Suitable when brightness increase is needed without wavelength shift.

All parts share identical electrical parameters (2.1V forward voltage, 20mA test current), mechanical dimensions (5mm, 10.10mm height), and compliance certifications, ensuring direct PCB compatibility and regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can C503B-ACN-CY0Z0341-030 be used as a direct replacement for C503C-ACN-CYAZA251?

A: Yes. Both parts maintain identical forward voltage (2.1V), test current (20mA), viewing angle (30°), and mechanical form factor (5mm round through-hole, 10.10mm height). The wavelength difference (590nm vs 591nm) and brightness increase (8930mcd vs 7980mcd) remain within amber LED specification tolerances. RoHS compliance and MSL ratings are identical.

Q: What is the brightness difference between the three parts?

A: C503C-ACN-CYAZA251 delivers 7980mcd, C503C-ACN-CYCZA251 delivers 8650mcd, and C503B-ACN-CY0Z0341-030 delivers 8930mcd, all at 20mA test current. The brightness variation reflects different LED die or phosphor configurations within the amber spectrum.

Q: Are there wavelength differences that affect color perception?

A: C503B-ACN-CY0Z0341-030 operates at 590nm while the other two operate at 591nm. Both wavelengths fall within the amber spectrum and produce visually equivalent amber color output. The 1nm difference is not perceptible in typical indication applications.

Q: Do all three parts have the same PCB footprint?

A: Yes. All three parts use identical through-hole radial packaging with 5mm lens diameter and 10.10mm maximum height, ensuring direct PCB compatibility without layout modifications.

Q: Are there inventory or lead time considerations?

A: Inventory levels differ: C503C-ACN-CYAZA251 (1041 pcs), C503B-ACN-CY0Z0341-030 (1577 pcs), and C503C-ACN-CYCZA251 (1361 pcs). Consult current stock status for procurement planning.
