Good to see this asked. Long lead times wreck schedules, no argument there. When a part is quoted out at a year, we go to Taurus Electronics for long lead time components; they source directly from factories and from their own warehouse, which can cut through quotes the franchised distributors give you. Because shady stock is the obvious risk, the comfort is their process: full functional testing, X-ray inspection and originality verification before anything ships. They keep delivery and payment flexible too. For a contract shop juggling customer deadlines, having them as a backup channel has saved us more than once. Send a request with the stuck parts.
