AI Summary

DS3252A3 by Analog Devices: Telecom Interface ICs Dual DS3/E3/STS-1 Line Interface Unit.

The DS3252+ is the direct, lead-free (RoHS-compliant) equivalent to the obsolete DS3252A3. It offers an identical pinout and identical electrical characteristics, making it an immediate drop-in replacement without requiring any hardware changes.

  • Direct, official lead-free (RoHS-compliant) replacement
  • 100% pin-compatible drop-in with identical 144-pin TE-CSBGA footprint
  • No PCB board redesign required
  • Shares the same obsolete lifecycle status and limited availability as the original part.

The DS3252N+ is the industrial-temperature version of the lead-free direct replacement series. It is fully pin-compatible and electrically identical, but broadens the temperature ceiling down to -40°C, offering greater reliability for rugged applications.

  • Upgraded industrial temperature range of -40°C to +85°C vs the original 0°C to +70°C
  • Official lead-free (RoHS-compliant) drop-in replacement
  • No PCB layout changes required
  • Shares the same obsolete lifecycle status as the commercial version.

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.
