FFF CompatibilityThe package footprint and 28-pin configuration are identical to the original PI5C3390Q, allowing direct mounting on the same PCB land pattern.Both are housed in a 28-pin 150-mil wide QSOP package with matching physical dimensions.The electrical ratings, 5-ohm low-resistance switch behavior, and 16-to-8 multiplexer functionality match perfectly.Shares the exact same pinout and 28-pin QSOP layout.Identical physical 28-pin QSOP package dimensions.Features 25-ohm switch series resistance compared to the original 5-ohm spec.
AI Summary

PI5C3390Q by Diodes Incorporated: Multiplexer/Demultiplexer 1 x 16:8 28-QSOP.

The QS3390QG is a direct equivalent and drop-in replacement in a 28-pin QSOP package. It shares the same 5-ohm on-resistance and logic pinout, though it is also classified as obsolete.

  • Direct functional equivalent with same 16-to-8 multiplexing architecture
  • Drop-in compatible 28-pin QSOP package footprint
  • Low 5-ohm switch on-resistance matches the original exactly
  • The part has been declared obsolete by Renesas, introducing identical lifecycle risk.

The QS32390QG is Renesas' alternative to the 25-ohm version (PI5C32390), offering drop-in package compatibility but with higher series resistance to mitigate high-speed noise reflections.

  • Same 28-pin QSOP footprint and drop-in pinout compatibility
  • Integrated 25-ohm resistors reduce signal reflections and noise in high-speed applications
  • Higher switch on-resistance (25-ohm typical vs 5-ohm original).
  • Classified as an obsolete component.

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.
