| FFF Compatibility | The 16-SOIC pin assignments, package dimensions, and footprint match the target CY2309CSXC-1H exactly with no PCB layout modifications required.Both use a standard 16-SOIC package (150-mil / 3.90mm body width) with surface-mount installation.Matches the 3.0V to 3.6V supply range, 133.33 MHz frequency ceiling, 1:9 fanout ratio, commercial temperature range (0°C to 70°C), and high-drive drive strength. | Pinout matches the original Cypress/Infineon assignments pin-for-pin.Utilizes the identical 16-SOIC 150-mil package and footprint.Meets or exceeds all performance parameters, and offers an upgraded industrial temperature tolerance. | ||
 AI Summary | CY2309CSXC-1H by Infineon Technologies: Fanout Buffer (Distribution), Zero Delay Buffer IC 133.33MHz 1 16-SOIC (0.154", 3.90mm Width). | The Renesas 2309-1HDCG is the most direct active replacement for the obsolete CY2309CSXC-1H. It provides identical electrical performance, high-drive outputs, and pinout compatibility in a standard 16-SOIC package, ensuring an effortless drop-in transition without redesigning the PCB.
| The Renesas 2309-1HDCGI offers a direct drop-in replacement with the added advantage of an upgraded operating temperature range (-40°C to +85°C). This makes it highly suitable for industrial applications or systems requiring increased safety margins over the original commercial-grade part.

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 CY2309CSXC-1H 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 CY2309CSXC-1H are the 2309-1HDCG (Renesas Electronics Corporation) and the 2309-1HDCGI (Renesas Electronics Corporation), out of 7 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 CY2309CSXC-1H 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.
