LED Indication - Discrete Procurement Notes

This component is officially classified as obsolete and no longer manufactured by Broadcom Limited. Procurement should focus on verified replacement part numbers such as HLMP-LB71-TUBDD. Buyers must confirm availability through authorized distributors or surplus suppliers, as original stock is exhausted. Verify that substitute components meet identical electrical and mechanical specifications to ensure compatibility with existing designs.

LED Indication - Discrete Selection Notes

Select this component only if the specific 4 mm super oval form factor and blue color are required for the application. Due to its obsolete status, direct sourcing is not possible; engineers must evaluate equivalent replacements from the same manufacturer family. Ensure that the replacement part maintains the same pinout, forward voltage characteristics, and luminous intensity to preserve system performance without redesigning the circuit board layout.

LED Indication - Discrete Part Context

The HLMP-LB72-UWPDD belongs to Broadcom’s discrete LED indication series, specifically utilizing the 4 mm super oval package style. This series is designed for general-purpose indicator applications where distinct visibility is necessary. The part number suffix indicates specific binning for wavelength and intensity. As an older generation component, it represents traditional through-hole LED technology before the widespread adoption of surface-mount alternatives.
