FFF CompatibilityIdentical 5-pin SOT323-5L package and pin configuration allows immediate board assembly without layout modifications.The SOT323-5L package dimensions and package footprint are exactly the same.The series termination resistor is 15 Ω instead of the original 33 Ω, which may alter signal transmission line impedance matching.Housed in a 6-pin TSOP-6 package instead of 5-pin SOT323-5L, which has different pin assignments and footprint geometry.Requires PCB redesign to accommodate the larger 6-pin package size and landing pattern.Provides the same downstream termination function with extremely similar series resistance (30 Ω vs 33 Ω) and capacitance (55 pF vs 47 pF) parameters.
AI Summary

USBDF01W5 by STMicroelectronics: RC (Pi) EMI Filter 2nd Order Low Pass 2 Channel R = 33Ohms, C = 47pF 5-TSSOP, SC-70-5, SOT-353.

A direct drop-in sibling from the same STMicroelectronics series that provides the identical 15 kΩ line termination and 47 pF line capacitance on the exact same footprint. The series resistor is reduced to 15 Ω, which should be evaluated for USB signal transmission line impedance matching.

  • Direct drop-in replacement on existing PCB footprint (SOT323-5L)
  • Identical 15 kΩ pull-down termination resistor
  • Identical 47 pF bypass capacitance value
  • Lower series resistor (15 Ω vs 33 Ω) might cause impedance mismatch depending on the USB transceiver driver strength
  • Obsolete status shares same lifecycle obsolescence risk as the queried part

An active downstream port terminator from onsemi that offers a very close electrical specification match. The series resistance is 30 Ω (vs 33 Ω) and capacitance is 55 pF (vs 47 pF). It requires a board redesign since it uses a 6-pin TSOP-6 package instead of the 5-pin SOT323-5L.

  • Active component status with reliable long-term distributor availability
  • Excellent series resistance match (30 Ω vs 33 Ω)
  • Identical 15 kΩ pull-down termination resistor
  • Requires board layout modification to transition from 5-pin SOT323-5L to 6-pin TSOP-6
  • Slightly higher typical line capacitance (55 pF vs 47 pF)

  • Find & compare verified second sources
  • Spot risk early with real-time part monitoring
  • Stay compliant and production-ready

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.
