C503C-ACS-CYCZA342 Equivalent & Substitute Parts

Part Overview

The C503C-ACS-CYCZA342 is an amber LED indicator with 5mm round through-hole packaging, designed for discrete indication applications. Manufactured by CreeLED, Inc., this component operates at 2.1V forward voltage with 8650mcd brightness output. The part is currently active in production with full RoHS compliance and unlimited moisture sensitivity rating. Substitute parts may be required due to inventory constraints, packaging format preferences, or specific brightness requirements within the compatible parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C503C-ACS-CYCZA342 is determined by strict parameter matching across critical electrical and mechanical specifications. The following parameters must remain constant for functional equivalence:

• Color: Amber
• Wavelength - Dominant: 591nm
• Lens Size: 5.00mm Dia
• Lens Style: Round with Domed Top
• Lens Transparency: Clear
• Voltage - Forward (Vf) (Typ): 2.1V
• Current - Test: 20mA
• Viewing Angle: 30°
• Mounting Type: Through Hole
• Package / Case: Radial

The identified substitute part C503B-ACS-CY0Z0252-030 meets all critical parameter requirements. Variations in millicandela rating (8650mcd vs. 8930mcd), height specification (12.80mm vs. 12.70mm), and packaging format (Tape & Box vs. Cut Tape) fall within acceptable tolerance ranges for this component category and do not affect functional compatibility in standard indication applications.

Parameter Comparison

Engineering Selection Recommendations

Both C503C-ACS-CYCZA342 and C503B-ACS-CY0Z0252-030 are active production components with full RoHS compliance and REACH unaffected status. Selection between these parts should be based on:

• Packaging requirements: Choose Tape & Box format for bulk reel applications; select Cut Tape format for smaller quantity orders or mixed component kits.
• Brightness tolerance: The substitute part provides 3.2% higher millicandela output (8930mcd vs. 8650mcd), which is acceptable for standard indication circuits where brightness variation within this range does not affect circuit function.
• Height specification: The 0.10mm height difference (12.70mm vs. 12.80mm) is negligible for through-hole PCB assembly and does not impact mechanical clearance in standard applications.

Both parts carry identical electrical specifications and are suitable for direct substitution in circuit designs without modification to drive circuitry or current-limiting resistor calculations.

Frequently Asked Questions (FAQ)

Q: Can C503B-ACS-CY0Z0252-030 be used as a direct replacement for C503C-ACS-CYCZA342?

A: Yes. Both parts share identical electrical characteristics (2.1V forward voltage, 20mA test current, 591nm wavelength) and mechanical form factor (5mm round through-hole radial package). The brightness difference (280mcd) and height variance (0.10mm) do not affect functional compatibility in standard indication applications.

Q: What is the difference between Tape & Box and Cut Tape packaging?

A: Tape & Box packaging supplies components on continuous reel tape with a protective box for storage and transport. Cut Tape packaging provides the same components pre-cut into individual strips. Selection depends on assembly process requirements and order quantity.

Q: Are there any compliance differences between these parts?

A: No. Both parts are RoHS compliant, REACH unaffected, and carry identical MSL rating (1 - Unlimited). They meet the same regulatory and environmental standards.

Q: Will the higher brightness of C503B-ACS-CY0Z0252-030 cause circuit compatibility issues?

A: No. The 3.2% brightness increase operates within the same forward voltage and test current specifications. Existing circuit designs require no modification. If brightness consistency is critical for visual matching in multi-LED applications, brightness binning data should be consulted.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, provided the assembly process accommodates the packaging format. Both parts have identical pin configuration, lead spacing, and through-hole mounting requirements. Packaging format selection affects only the component feeder setup during automated assembly.
