LED AMBER CLEAR 5MM ROUND T/H C503C-ACS-CYCZA251 Equivalent & Substitute Parts

Part Overview

The C503C-ACS-CYCZA251 is an amber 591nm LED indication component in a 5mm round through-hole package manufactured by CreeLED, Inc. This discrete 2.1V radial LED is designed for standard indication applications requiring amber wavelength output. The part is currently active in production status with 870 pieces in stock. Substitute parts become necessary when primary inventory is depleted, when alternative sourcing is required for supply chain continuity, or when design flexibility permits selection from parametrically equivalent alternatives within the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the C503C-ACS-CYCZA251 is determined by strict equivalence across the following critical parameters:

• Wavelength - Dominant: 591nm (amber specification)
• Voltage - Forward (Vf) (Typ): 2.1V (electrical compatibility)
• Current - Test: 20mA (operational current)
• Viewing Angle: 30° (optical performance)
• Mounting Type: Through Hole (mechanical compatibility)
• Lens Size: 5.00mm Dia (form factor)
• Lens Style: Round with Domed Top (physical configuration)
• Color: Amber (functional requirement)
• Lens Transparency: Clear (optical characteristic)
• RoHS Status: RoHS Compliant (regulatory compliance)

The identified substitute parts C503B-ACS-CY0Z0251 and C503B-ACS-CY0Z0251-030 meet all critical electrical and mechanical parameters. Minor variations in millicandela rating (8930mcd versus 8650mcd) and maximum height (12.70mm versus 12.80mm) fall within acceptable tolerance ranges for parametric equivalence in this component category.

Parameter Comparison

Engineering Selection Recommendations

All three parts—C503C-ACS-CYCZA251, C503B-ACS-CY0Z0251, and C503B-ACS-CY0Z0251-030—are active production components manufactured by CreeLED, Inc. with identical RoHS compliance and REACH unaffected status. Selection among these alternatives is based on availability and inventory levels rather than electrical or mechanical performance differences.

The C503B-ACS-CY0Z0251-030 variant offers the highest current inventory (1631 pieces) and represents the most readily available option. The C503B-ACS-CY0Z0251 provides an intermediate inventory level (743 pieces). The primary part C503C-ACS-CYCZA251 maintains 870 pieces in stock.

All parts satisfy identical regulatory requirements and operational specifications for through-hole amber LED indication applications at 2.1V forward voltage and 20mA test current.

Frequently Asked Questions (FAQ)

Q: Can C503B-ACS-CY0Z0251 and C503B-ACS-CY0Z0251-030 be used interchangeably with C503C-ACS-CYCZA251?

A: Yes. Both substitute parts meet all critical electrical and mechanical parameters: 591nm wavelength, 2.1V forward voltage, 20mA test current, 5.00mm lens diameter, 30° viewing angle, through-hole mounting, and round domed lens configuration. Minor differences in millicandela rating (8930mcd versus 8650mcd) and maximum height (12.70mm versus 12.80mm) do not affect functional equivalence for standard indication applications.

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

A: Both parts are parametrically identical across all electrical and mechanical specifications. The "-030" suffix indicates a packaging or distribution variant. Both maintain identical performance characteristics and are suitable for direct substitution.

Q: Are all three parts RoHS compliant?

A: Yes. C503C-ACS-CYCZA251, C503B-ACS-CY0Z0251, and C503B-ACS-CY0Z0251-030 are all RoHS compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What determines whether a part can substitute for the C503C-ACS-CYCZA251?

A: Substitution is determined by equivalence across dominant wavelength (591nm), forward voltage (2.1V), test current (20mA), lens size (5.00mm), viewing angle (30°), mounting type (through-hole), lens style (round domed), color (amber), and lens transparency (clear). All identified substitutes meet these criteria.

Q: Can these parts be used in PCB-mounted applications?

A: No. All three parts are specified for through-hole mounting only. They are not suitable for surface-mount or PCB-mounted applications without mechanical adaptation.
