AI Summary

PCA9517ADP by NXP: Interface - Signal Buffers, Repeaters Bus buffer.

The TCA9517A from Texas Instruments is a direct, active second-source replacement for NXP's obsolete PCA9517ADP. It matches the improved hot-swap capability and high ESD tolerance of the 'A' version of the original series.

  • True drop-in pin-to-pin replacement
  • Widely available and active lifecycle status
  • Identical supply voltage ranges (VCCA: 0.9V to 5.5V, VCCB: 2.7V to 5.5V)

The TCA9517 is the non-A version from Texas Instruments. It functions as a direct drop-in replacement with minor tradeoffs in ESD protection thresholds compared to the 'A' variant.

  • Direct pin-to-pin drop-in footprint match
  • Supports identical voltage translation ranges (VCCA: 0.9V to 5.5V, VCCB: 2.7V to 5.5V)
  • Cost-effective and highly available option
  • Slightly lower ESD tolerance compared to the 'A' variant

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.
