TRANSISTOR OUTPUT OPTOCOUPLER — what the part is
The TIL118-2 is a TRANSISTOR OUTPUT OPTOCOUPLER, a classic through-hole isolation component that provides galvanic isolation between input and output circuits using an infrared LED optically coupled to a phototransistor.
RoHS non-compliant — a sourcing constraint
The TIL118-2 is marked RoHS non-compliant. For legacy designs or repair applications where lead-free solder is not required, this is acceptable. However, for any new assembly line that must meet RoHS directives, this part will not pass process qualification. Confirm your board's soldering requirements before committing the BOM line.
Bulk packaging — manual assembly context
That suits hand-insertion or low-volume through-hole production, but is not optimized for high-speed automated pick-and-place. If your line requires reeled parts, verify the supplier's packaging options at quote time.
