Substitute Part Grouping Explanation

Substitute parts for the C503C-ACN-CYAZA341 are qualified based on the following critical parameters that determine functional and mechanical interchangeability:

Electrical Compatibility:

• Forward voltage (Vf): 2.1V (identical across all parts)
• Test current: 20mA (identical across all parts)
• Color: Amber (identical across all parts)
• Wavelength - Dominant: 591nm or 590nm (within amber spectrum tolerance)

Mechanical Compatibility:

• Lens size: 5.00mm Dia (identical across all parts)
• Lens style: Round with Domed Top (identical across all parts)
• Lens transparency: Clear (identical across all parts)
• Mounting type: Through Hole Radial (identical across all parts)
• Height (Max): 10.10mm (identical across all parts)
• Viewing angle: 30° (identical across all parts)

Regulatory & Environmental:

• RoHS Compliance: All parts RoHS compliant
• MSL Rating: 1 (Unlimited) for all parts
• REACH Status: REACH Unaffected for all parts
• Product Status: Active for all parts

Millicandela rating variations (7980mcd to 8930mcd) fall within acceptable brightness tolerance for indication applications and do not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with identical RoHS compliance and REACH unaffected classification, ensuring regulatory continuity in design implementations. The C503C-ACN-CYAZA341 and C503C-ACN-CYCZA251 share identical base product numbers and dominant wavelengths (591nm), providing direct functional equivalence. The C503B-ACN-CY0Z0341-030 operates at 590nm wavelength, which remains within the amber spectrum and maintains electrical compatibility at 2.1V forward voltage.

Brightness variations across the three parts (7980mcd, 8930mcd, and 8650mcd respectively) reflect manufacturing tolerance ranges typical for LED indication applications. Selection between parts should be based on inventory availability and specific brightness requirements for the target application. All parts are suitable for direct substitution in through-hole PCB designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can C503B-ACN-CY0Z0341-030 replace C503C-ACN-CYAZA341 in production designs?

A: Yes. Both parts operate at identical forward voltage (2.1V), test current (20mA), and mechanical specifications (5mm round through-hole radial package, 10.10mm height). The wavelength difference (590nm vs 591nm) remains within amber spectrum tolerance. Brightness difference (8930mcd vs 7980mcd) is within acceptable indication application tolerance.

Q: What is the primary difference between C503C-ACN-CYCZA251 and C503C-ACN-CYAZA341?

A: Both parts share the same base product number (C503C) and dominant wavelength (591nm). The primary difference is millicandela rating: C503C-ACN-CYCZA251 delivers 8650mcd compared to 7980mcd for C503C-ACN-CYAZA341. Electrical and mechanical specifications are identical.

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

A: Yes. All three parts carry RoHS Compliant status and REACH Unaffected classification, meeting regulatory requirements for consumer and industrial electronics.

Q: Do these parts require different PCB footprints?

A: No. All three parts use identical through-hole radial mounting with 5.00mm lens diameter and 10.10mm maximum height, requiring no PCB layout modifications for substitution.

Q: Which part should be selected for maximum brightness?

A: C503B-ACN-CY0Z0341-030 provides the highest brightness at 8930mcd, followed by C503C-ACN-CYCZA251 at 8650mcd, and C503C-ACN-CYAZA341 at 7980mcd. Selection depends on specific illumination requirements for the target application.
