AI Summary

LT1584CT by Analog Devices: Linear Voltage Regulator IC 1 Output TO-220-3.

This is the direct lead-free (RoHS compliant) version of the original LT1584CT. It is a drop-in replacement with identical electrical and physical specifications, making it the highest reliability option.

  • Direct lead-free (RoHS compliant) equivalent from the original manufacturer.
  • Maintains the identical 7A output current capability.
  • Exact identical physical package and TO-220-3 pinout assignment.

This sibling part from Analog Devices is a pin-compatible drop-in option in the same TO-220-3 footprint. However, its output current is restricted to 5A, making it a partial functional alternative depending on application requirements.

  • Pin-compatible drop-in in the same TO-220-3 package.
  • From the same original manufacturer (Analog Devices Inc.).
  • Higher maximum input voltage (30V vs 7V) offers increased voltage headroom.
  • Lower maximum output current (5A vs 7A).
  • Slightly higher dropout voltage of 1.5V at 5A vs 1.4V at 7A for the original.

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.
