FFF CompatibilityBoth parts share the exact same 8-lead plastic SOIC footprint (S8 package) and pinout assignment.The packages are identical in material, style, and physical dimensions; the replacement is simply lead-free.All electrical specifications, output voltage, input voltage range, and maximum current limits are identical.Both devices use the standard 8-pin SOIC (S8/SOIC-8) package with compatible pinout configurations.Both are standard surface mount 8-pin SOIC packages with interchangeable physical dimensions.The MIC5209-5.0YM-TR provides a lower maximum output current (500mA vs 700mA) and has a lower maximum input voltage rating (16V vs 30V).
AI Summary

LT1129CS8-5 by Analog Devices: Linear Voltage Regulator IC 1 Output 700mA 8-SO.

This is the official lead-free (PBF) version of the exact same regulator. It is fully compatible in fit, form, and function with zero tradeoffs.

  • Lead-free (Pb-free) version of the original source part
  • Identical electrical specifications and maximum ratings
  • Perfect drop-in replacement with identical package, pinout, and footprint

The MIC5209-5.0YM-TR is the tape-and-reel version of MIC5209-5.0YM. It is a physical drop-in replacement but has lower maximum output current (500mA vs 700mA) and lower maximum input voltage (16V vs 30V).

  • Drop-in footprint replacement with 8-pin SOIC package
  • Identical 5V fixed output voltage
  • Lower operating quiescent current: 80 uA vs 310 uA typical
  • Lower maximum output current: 500mA vs 700mA
  • Lower maximum operating input voltage: 16V vs 30V

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.
