No last-time-buy or end-of-life notice is in effect. For BOM planning, this means the 63S281ANL remains available through the independent distribution channel without the timeline pressure of a phase-out. RoHS non-compliant — verify your assembly's exemption allowance for lead-bearing solder if the application requires it. ## Package and handling note Supplied in Bulk (tubes or trays), not tape-and-reel. For pick-and-place lines, you will need to transfer to a feeder-compatible carrier or hand-place. The 20-PLCC J-Lead footprint matches standard PLCC-20 land patterns; the 9x9 mm body fits sockets as well as soldered joints. The 0°C to 75°C commercial range limits this part to indoor, temperature-controlled environments — not suitable for industrial or automotive under-hood use without additional thermal management.","metaTitle":"63S281ANL PROM 1Kbit Parallel 40 ns 20-PLCC, Active","metaDescription":"63S281ANL is an Active 1Kbit PROM with 40 ns access time, parallel interface, 4.75V~5.25V supply, 20-PLCC package.
