Alternatives to Burr-Brown REF200AU
Burr-Brown REF200AU and its qualified second sources, compared on form/fit/function, stock, lifecycle and price — the same checks Parter runs inside a BOM.

|---|---|---|---|---|
| FFF Compatibility | Identical SOIC-8 package and pinout, allowing for a seamless, drop-in substitution.Identical package dimensions and mounting footprint.Matches all electrical specifications, including the 2.5V to 40V compliance and ±0.25% accuracy. | The pin assignments are completely different, and it lacks the dual-source and mirror layout, requiring a schematic and PCB redesign.Available in the same SOIC-8 physical package size.Provides a single adjustable current source instead of dual 100µA sources and a 1:1 current mirror. Accuracy is lower (±6% vs ±0.25%) and it has a positive temperature coefficient of +0.33%/°C unless temperature-compensated with external diodes. | ||
 AI Summary | REF200AU by Burr-Brown: Dual current sink/ current source IC. | This is a direct, drop-in sibling from the same product series. It features the exact same silicon design and package, with the 'G4' suffix designating TI's green/lead-free packaging standards, making it the ideal direct replacement.
| The LM334M is an adjustable three-terminal current source in an SOIC-8 package that can be programmed to 100µA using an external resistor. While it is a highly economical and available alternative, it only provides a single current source (lacking the second source and current mirror of the REF200) and requires external components for temperature compensation.
