FFF CompatibilityBoth parts share the identical 48-lead TSSOP package and pin assignment.The physical package, dimensions, and JEDEC MO-153 standard outline are exactly the same.The electrical parameters, data rate, supply voltages, and temperature ranges are identical.Employs a 24-lead TSSOP package with a different pin count and layout, requiring board redesign.The physical footprint is smaller (24-TSSOP vs 48-TSSOP), requiring two devices to cover the 8-port requirement.Provides 4 channels of the same repeater performance, allowing 2 devices to fully replicate the 8-channel design.
AI Summary

FIN1108MTD by onsemi: Buffer, ReDriver 8 Channel 800Mbps 48-TSSOP.

This is the identical silicon and package variant from the same series, differing only by packing method. The obsolete/LTB MTD suffix denotes tube packaging, whereas the active MTDX suffix denotes tape-and-reel packaging, providing an immediate drop-in replacement.

  • Direct drop-in replacement on the exact same silicon and package layout
  • Identical electrical characteristics with 800 Mbps maximum data rate and 3.3 V supply operation
  • Active lifecycle status, offering immediate path forward from the obsolete/LTB part number

Since the original 8-channel series is mature, migrating to two 4-channel repeaters from the same family provides a robust functional alternative. Although this requires a board redesign, it utilizes the active and widely available FIN1104 series.

  • Active lifecycle status with wide ongoing availability
  • Same high performance with 800 Mbps speed and 1.75 ns delay time
  • Reduces channel crosstalk by split layout placement
  • Requires a board layout redesign to accommodate two 24-TSSOP packages instead of one 48-TSSOP package
  • Marginally higher total footprint area and component count on the PCB

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.
