| FFF Compatibility | Pinout is extremely similar; however, Pin 17 is tied to Ground (VSS) on the ISSI alternative, whereas it is a No Connect (NC) on the obsolete Cypress part. It is a drop-in if Pin 17 on the PCB layout is left floating or tied to Ground.Both devices are packaged in the standard 100-pin TQFP/LQFP package with identical physical body dimensions (14 mm x 20 mm).Direct functional equivalent utilizing No Latency Pipelined (NoBL compatible) synchronous architecture, with superior speed ratings (200 MHz, 3.1 ns) and matching 3.3V supply voltage range. | Pin 17 is tied to Ground (VSS) on the ISSI alternative, whereas it is a No Connect (NC) on the obsolete Cypress part. It is a drop-in if Pin 17 on the PCB layout is left floating or tied to Ground.Both devices are packaged in the standard 100-pin TQFP/LQFP package with identical physical body dimensions (14 mm x 20 mm).The device is functionally compatible but only rated for the Commercial temperature range (0°C to +70°C), whereas the original Cypress part supports the Industrial temperature range (-40°C to +85°C). | ||
 AI Summary | CY7C1354C-166AXI by Infineon Technologies: SRAM - Synchronous, SDR Memory IC 9Mbit Parallel 166 MHz 3.5 ns 100-TQFP (14x20). | The IS61NLP25636B-200TQLI is the highest-confidence active replacement. It matches the obsolete Cypress NoBL architecture, voltage, and industrial temperature range, while offering slightly improved speed ratings. Pin 17 is routed to Ground instead of being a No Connect, requiring verification of the host PCB layout.
| This commercial-grade variant of the ISSI series provides identical footprint and electrical advantages over the original part. However, it is only suitable for applications that do not require the extended industrial temperature range of the obsolete target.

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 CY7C1354C-166AXI 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 CY7C1354C-166AXI are the IS61NLP25636B-200TQLI (ISSI, Integrated Silicon Solution Inc) and the IS61NLP25636B-200TQL (ISSI, Integrated Silicon Solution Inc), out of 3 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 CY7C1354C-166AXI 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.
