If your BOM calls for extended temperature, an industrial-grade SRAM in the same density and package family would be the correct cross-shop. ## Through-hole PDIP — board-level fit and handling The 24-pin PDIP (0.300 inch body width, 7.62 mm row spacing) is a through-hole package intended for socketed or wave-soldered boards. The tube shipping medium is standard for DIP devices. ## Obsolete — sourcing reality and what to expect No last-time-buy window remains open through the original manufacturer. If the BOM can tolerate a footprint change, a current-production 16 Kbit asynchronous SRAM in a 28-pin SOIC or TSOP may offer a lower total cost of ownership, but the PDIP-24 form factor limits drop-in alternatives.","metaTitle":"Cypress CY7C128A-35PC 16Kbit Asynchronous SRAM, 35 ns","metaDescription":"Cypress CY7C128A-35PC 16Kbit (2K x 8) asynchronous SRAM with 35 ns access time in a 24-pin PDIP package. 4.5V–5.5V supply, 0°C–70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tube","Technology":"SRAM - Asynchronous","Access Time":"35 ns","Memory Size":"16Kbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Through Hole","Package / Case":"24-DIP (0.300\\\", 7.62mm)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"CY7C128A","Memory Organization":"2K x 8","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"24-PDIP","Write Cycle Time - Word, Page":"35ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ab05321fe2552bdbd2e984ac4b11b7b6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C128A-35PC obsolete?","answer":"Yes, Cypress has declared the CY7C128A-35PC obsolete. No further production or last-time-buy is available from the original manufacturer.

For a new design, consider a 16 Kbit asynchronous SRAM in a 28-pin SOIC or TSOP package, but the board layout must change.
