FFF CompatibilitySame pinout and pin assignment as the queried part.Same 8-SOIC package physical dimensions.Same electrical parameters and identical internal silicon.Completely different pinout and requires external setting resistors.Standard SOIC-8 package with matching land pattern.Provides only a single adjustable current source instead of dual 100µA sources and a current mirror. Lower baseline accuracy (6% vs 0.25%).
AI Summary

REF200AU by Burr-Brown: Dual current sink/ current source IC.

This is the active tape-and-reel ordering code of the exact same REF200AU device. It is a direct, drop-in replacement with identical electrical and physical properties.

  • Direct, 100% identical drop-in replacement part.
  • Same 8-SOIC package and footprint.
  • Same high accuracy (0.25%) and low temperature coefficient.

This is an adjustable 3-terminal current source in a matching SOIC-8 package. It can be set to 100µA using an external resistor but lacks the dual-channel capability, high precision, and integrated Wilson current mirror of the REF200.

  • Highly available, cost-effective active part.
  • Fits on the same physical SOIC-8 footprint.
  • Adjustable output range from 1µA to 10mA.
  • Requires external programming resistors.
  • Much lower baseline accuracy (±6% vs. ±0.25%).

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.
