If your design needs margin, a 8 ns or 7 ns grade in the same family exists, but those are also obsolete and harder to find. ## Package and footprint — 44-SOJ The 44-SOJ package is a surface-mount, J-bend lead form with a 0.400\" body width (10.16 mm). It is a through-hole-like footprint for soldering, common in 1990s–2000s SRAM designs. The supplier device package is 44-SOJ. If your board was laid out for a 44-pin TSOP-II, this part will not fit — verify the footprint before ordering. The shipping medium is Tube, not tape-and-reel, so plan for manual placement or tube-fed pick-and-place if your line supports it.","metaTitle":"CY7C1041D-10VXI SRAM 4Mbit, 10 ns, 44-SOJ, Obsolete","metaDescription":"Infineon CY7C1041D-10VXI 4Mbit asynchronous SRAM, 10 ns access time, 44-SOJ, -40°C to 85°C.

Infineon has discontinued production.

These are also aging parts; newer designs should consider a 3.3V TSOP or BGA SRAM with a voltage translator."},{"question":"Where can I buy CY7C1041D-10VXI available via RFQ confirmation?","answer":"We source the CY7C1041D-10VXI through independent distribution and surplus channels.
