If your program footprint is pushing past 40 KB, this CPU leaves almost no headroom for online changes or additional function blocks. ## Lifecycle reality — EOL hot, no official successor For a line-down situation, the only sourcing route is the independent surplus and broker market. We can quote this part to order against an RFQ, but availability is not guaranteed — confirm the BOM quantity and we will search the open channel.","metaTitle":"Siemens 6ES7315-1AF01-0AB0 S7-300 CPU 315, 48 KB, EOL Hot","metaDescription":"Siemens 6ES7315-1AF01-0AB0 S7-300 CPU 315 with 48 KB working memory, 24 V DC integrated supply.
