FFF CompatibilityThe package size (6-XFDFN) and pin count (6-pin vs 8-pin) are different from the original device, requiring a PCB layout redesign.The device has smaller dimensions (1.40 mm x 1.35 mm) compared to the original Micro QFN-8L package (2.50 mm x 1.20 mm).The device lacks the dedicated VBUS and ID pin ESD protection diodes present on the original ECMF02-4CMX8.
AI Summary

ECMF02-4CMX8 by STMicroelectronics: 2 Line Common Mode Choke Surface Mount DCR 4Ohm.

This is the official manufacturer-recommended alternative from STMicroelectronics' newer product family. It provides excellent common-mode filtering and ESD protection for the USB 2.0 D+/D- lines, though it lacks the integrated VBUS and ID pin ESD lines, requiring external protection for those nets.

  • Official manufacturer recommended replacement line
  • Optimized for high-speed data lines up to HDMI 2.1 and USB4 speeds
  • Extremely compact 6-XFDFN package (1.40 mm x 1.35 mm)
  • Lacks VBUS and ID pin ESD protection lines
  • Requires board redesign due to different package footprint and pin count

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.
