Procurement Notes

Verify RoHS compliance status through official datasheets or manufacturer documentation prior to integration. Confirm moisture sensitivity level requirements against IPC/JEDEC standards for storage and handling. Ensure that the specific ordering suffix matches the required color temperature and luminous intensity specifications for the target application design.

Selection Notes

Select this component when a compact SMD form factor with high brightness is required. The PLCC-2 package facilitates automated assembly. Consider the 8000K color temperature for applications demanding a cool white appearance. Verify thermal management capabilities given the 108 mW power rating and operating temperature limits.

Part Context

This part belongs to the ASMT series of high-power LEDs manufactured by Broadcom Limited. The series is characterized by robust construction suitable for industrial and commercial use. The ZAAC2 suffix denotes specific optical and thermal characteristics within the broader product family, distinguishing it from other variants in terms of color and intensity.

Replacement Considerations

Direct substitutes may include other PLCC-2 white LEDs from manufacturers such as Osram or Cree. Verify pin compatibility, forward voltage, and luminous intensity before substitution. Cross-reference datasheets to ensure equivalent thermal resistance and mechanical dimensions.
