That means the manufacturer has stopped production and there is no committed last-time-buy window — any remaining stock in the channel is the final supply. For sustainment programs, the immediate action is to secure inventory against the BOM quantity while units are still available from distributors. ## Sourcing and availability for the BOM line Because this part is obsolete, availability is limited to existing distributor stock. We source the 1.5KE16ARL4 against an RFQ — no stock-holding claim, but we can check multi-source inventory and provide a quote for the quantity your BOM requires.","metaTitle":"1.5KE16ARL4 onsemi Circuit Protection TVS – Obsolete","metaDescription":"1.5KE16ARL4 from onsemi, Circuit Protection TVS diode, Bulk package.
