Engineering Selection Recommendations

The C503B-GAS-CD0E0891 is the designated substitute for the obsolete C503B-GAS-CC0D0891. Selection is supported by the following factors:

Product Status: The substitute part maintains active production status with CreeLED, Inc., ensuring ongoing supply availability and manufacturing consistency.

Regulatory Compliance: Both parts maintain identical REACH Unaffected status and Moisture Sensitivity Level 1 (Unlimited) classification, confirming equivalent environmental and regulatory standing.

Mechanical Interchangeability: Identical through-hole radial mounting configuration, 5mm lens diameter, round domed lens style, and 13.30mm maximum height ensure direct physical compatibility in existing PCB designs without layout modifications.

Electrical Compatibility: Forward voltage differential of 0.2V (3.2V vs. 3V) and dominant wavelength variance of 3nm (530nm vs. 527nm) remain within acceptable green LED specification tolerances for indication applications. Both parts operate at identical 20mA test current and 15° viewing angle.

Frequently Asked Questions (FAQ)

Q: Can the C503B-GAS-CD0E0891 be used as a direct replacement without circuit modifications?

A: Yes. The substitute part maintains identical mechanical dimensions, mounting type, and electrical operating parameters within acceptable tolerances. No PCB layout or circuit design changes are required.

Q: What is the significance of the 0.2V forward voltage difference between the main part and substitute?

A: The forward voltage difference (3.2V vs. 3V) is within standard LED specification tolerances for green indication LEDs. Both parts operate at the same 20mA test current. Circuit designs accommodating typical LED forward voltage variation will function without modification.

Q: How does the 3nm wavelength difference (530nm vs. 527nm) affect visual appearance?

A: Both wavelengths fall within the green spectrum and are visually indistinguishable in indication applications. The dominant wavelength variance of 3nm is within manufacturing tolerance for green LEDs and does not affect functional performance or color perception in standard indication circuits.

Q: Why is the main part classified as obsolete?

A: Product obsolescence reflects CreeLED, Inc.'s manufacturing and inventory decisions. The active substitute part C503B-GAS-CD0E0891 provides equivalent functionality and ensures continued component availability for new designs and field service applications.

Q: Are there any packaging differences between the main part and substitute?

A: The main part is specified with standard packaging, while the substitute is supplied in bulk packaging. Both maintain identical through-hole radial form factor and physical dimensions. Packaging classification does not affect component performance or interchangeability.

Q: What compliance certifications apply to both parts?

A: Both the main part and substitute maintain REACH Unaffected status and Moisture Sensitivity Level 1 (Unlimited) classification, confirming equivalent regulatory compliance for industrial and commercial applications.
