Parameter Comparison

Engineering Selection Recommendations

The C503B-GAS-CD0E0781 is the direct substitute for the obsolete C503B-GAS-CC0D0781. Both components are manufactured by CreeLED, Inc., and share identical mechanical form factors, mounting configurations, and regulatory compliance profiles.

The substitute part is currently in active production status, ensuring availability for new designs and production continuity. Both parts maintain REACH Unaffected status and EAR99 ECCN classification, with no additional compliance considerations required for substitution.

The forward voltage differential of 0.2V (3.2V vs. 3V) and wavelength variation of 2nm (525nm vs. 527nm) fall within standard green LED specification tolerances and do not impact functional compatibility in indication applications.

Frequently Asked Questions (FAQ)

Q: Can C503B-GAS-CD0E0781 be used as a direct replacement for C503B-GAS-CC0D0781?

A: Yes. Both components share identical mechanical dimensions, mounting type, lens configuration, and electrical test parameters. The forward voltage and wavelength variations are within acceptable tolerances for green LED indication circuits.

Q: What is the significance of the product status change from Obsolete to Active?

A: The substitute part is in active production, ensuring long-term availability and supply chain stability. The obsolete status of the original part necessitates transition to the active substitute for ongoing production requirements.
