No factory last-time-buy window remains. Sourcing now runs through independent distribution — sealed factory tubes or pulled lots with consistent date-codes. If you are freezing a BOM that still calls this part, verify the date-code spread and condition before committing the line. That covers office equipment, test gear, and indoor industrial controllers, but not engine bays, outdoor telecom cabinets, or unheated warehouses. If the board sees condensation or winter startup, this part needs a conformal coat and a derating review on the thermal curve.","metaTitle":"Cypress CY7C199C-25PC 256Kbit SRAM, 25 ns, 28-PDIP","metaDescription":"Cypress CY7C199C-25PC 256Kbit asynchronous SRAM, 25 ns access, 4.5V-5.5V, 28-PDIP.
