FFF CompatibilityThe pinout assignment is identical, and it uses the same 16-pin TSSOP footprint with a 0.65 mm pitch.Both parts are in standard 16-pin TSSOP packages (4.40 mm body width) with matching mechanical specifications.Operating parameters such as a 3.3V supply voltage, 1:8 output ratio, select decoding logic tables, and industrial temperature range match or exceed the original part.It is the exact same base silicon design, pinout, and 16-pin TSSOP physical package.Both devices share the same 16-pin TSSOP body and physical footprint dimensioning.This is the commercial temperature range version (0°C to 70°C) rather than the original industrial range (-40°C to 85°C).
AI Summary

CY2308ZXI-1HT by Infineon Technologies: Fanout Buffer (Distribution), Zero Delay Buffer IC 133.3MHz 1 16-TSSOP (0.173", 4.40mm Width).

The CDCVF25081PW is an active 3.3V PLL-based zero delay buffer from Texas Instruments. It features the exact same pin layout, input/output ratio, select logic decoding, and TSSOP-16 package, making it an excellent active drop-in replacement. Additionally, it offers a wider clock frequency range (up to 200 MHz) and integrated series damping resistors to improve signal integrity.

  • Active lifecycle status, offering long-term availability.
  • Identical pinout configuration allowing a seamless drop-in replacement on existing board layouts.
  • Broader frequency support up to 200 MHz (vs. 133.3 MHz on the original device).
  • The integrated 25-ohm series damping resistors may slightly alter output slew rates compared to the un-resisted high-drive outputs of the original CY2308-1H, though this generally improves signal integrity.

The CY2308ZXC-1HT is a direct sibling of the obsolete part, sharing the same physical TSSOP-16 package, pin assignment, and high-drive (-1H) characteristics. However, it is rated for the commercial temperature range (0°C to 70°C) instead of the original industrial range (-40°C to 85°C). It remains active and available through authorized specialty distributors such as Rochester Electronics.

  • Direct family sibling retaining the exact same internal design architecture and timing characteristics.
  • Identical package footprint enabling instant board-level replacement.
  • Fully active and stocked through authorized aftermarket channels like Rochester Electronics.
  • Reduced operating temperature range (0°C to 70°C vs. -40°C to 85°C), making it unsuitable for harsh industrial environments.

You searched one part. Parter watches your whole BOM.

  1. 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.

  2. 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.

  3. 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.
