The 550-0705F is a 5mm through-hole bi-color LED assembly manufactured by Dialight, designed for applications requiring dual-color indication in a compact form factor. The device features a PBT housing with square back configuration and is available in red/green (R/G) or yellow/green (Y/G) color combinations, with separate cathode leads for each color. It is RoHS compliant and compatible with wave soldering, dip soldering, or hand soldering using lead-free processes at maximum 260°C for 5 seconds. The LED housing dimensions are approximately 6.10 mm in diameter with lead dimensions of 2.54 mm ±0.38 mm, and the device meets electrostatic discharge (ESD) handling requirements per IPC-A-610. This bi-color LED is commonly used in status indication, alarm signaling, and diagnostic applications where space-constrained designs require dual-state visual feedback.
