Obsolete — plan the last-time-buy or replacement now
This part is obsolete per the manufacturer. No successor order code is listed. For new builds, source surplus or broker channel. For legacy support, we source to order against an RFQ.
Temperature grade and environment
Rated for 0°C to 70°C (commercial temperature range). That limits this part to indoor, climate-controlled equipment — no outdoor telecom cabinets, no engine-bay electronics, no condensation-prone environments. If the system sees extended temperature, look for an industrial-grade QDR SRAM in the same footprint.
