 AI Summary | CY7C1339G-133AXCT by Infineon Technologies: SRAM - Synchronous, SDR Memory IC 4Mbit Parallel 133 MHz 4 ns 100-TQFP (14x20). | This is the commercial temperature version of the same memory family in tray packaging rather than Tape & Reel. It provides an absolute drop-in replacement requiring zero design changes, though it likely shares the same obsolete status and long-term availability risks as the queried part.
| This is an active, industrial-grade synchronous SRAM alternative from GSI Technology. It provides a higher clock frequency of 150 MHz and a wider temperature range while keeping the exact same physical package size and matching the standard JEDEC pinout.

You searched one part. Parter watches your whole BOM.
All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
Yes. The Infineon Technologies CY7C1339G-133AXCT is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
The closest qualified second sources for the Infineon Technologies CY7C1339G-133AXCT are the CY7C1339G-133AXC (Infineon Technologies) and the GS84032CGT-150I (GSI Technology), out of 4 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the CY7C1339G-133AXCT are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
