Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C503B-GCS-CB0C0891 is determined by strict parameter matching across electrical and mechanical specifications. All substitute parts must maintain identical values for the following critical parameters: color (Green), dominant wavelength (527nm), lens size (5.00mm), lens style (Round with Domed Top), lens transparency (Clear), forward voltage (3.2V), test current (20mA), millicandela rating (24850mcd), viewing angle (30°), mounting type (Through Hole), package type (Radial), and compliance certifications (RoHS Compliant, MSL Level 1).

The substitute parts are grouped into two categories based on physical height variation:

Direct Manufacturer Substitutes (Height: 10.30mm): C503B-GCN-CB0C0781 and C503B-GCN-CB0C0891 represent direct alternatives with identical electrical performance but reduced maximum height. These parts are suitable for applications where vertical space constraints exist.

Parametric Equivalent (Height: 12.70mm): C503B-GCS-CB0C0781 maintains the original height specification of 12.70mm while providing equivalent electrical and optical performance.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and full RoHS compliance, ensuring regulatory alignment with current environmental and safety standards. The selection between substitute options depends solely on physical height constraints within the target application.

For applications with standard vertical clearance requirements, C503B-GCS-CB0C0781 provides direct substitution with identical 12.70mm maximum height specification. For space-constrained designs requiring reduced height, C503B-GCN-CB0C0781 and C503B-GCN-CB0C0891 offer 10.30mm maximum height while maintaining all electrical and optical parameters. All parts carry MSL Level 1 rating, indicating unlimited shelf life and no moisture sensitivity precautions during storage or handling.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the C503B-GCS-CB0C0891?

A: Substitute parts must match all electrical parameters (3.2V forward voltage, 20mA test current), optical specifications (527nm wavelength, 24850mcd intensity, 30° viewing angle), physical form factor (5mm round domed clear lens, through-hole radial package), and compliance certifications (RoHS Compliant, MSL Level 1). Height variation is the only allowable difference among qualified substitutes.

Q: Can I use the shorter 10.30mm height parts as direct replacements?

A: Yes, C503B-GCN-CB0C0781 and C503B-GCN-CB0C0891 are electrically and optically identical to the C503B-GCS-CB0C0891. The reduced height makes them suitable for applications where vertical space is limited. Verify that your PCB layout and mechanical enclosure accommodate the 10.30mm maximum height before implementation.

Q: Are all substitute parts from the same manufacturer?

A: All substitute parts are manufactured by CreeLED, Inc., the same manufacturer as the primary part, ensuring consistent quality and performance standards.

Q: What is the significance of the MSL Level 1 rating?

A: MSL Level 1 indicates unlimited moisture sensitivity level, meaning these parts require no special moisture control during storage, handling, or assembly. Standard warehouse conditions are sufficient for component preservation.

Q: Do all parts meet the same compliance requirements?

A: All listed parts are RoHS Compliant and REACH Unaffected, meeting current environmental regulations for electronic component manufacturing and use in regulated markets.
