FFF CompatibilityPerfectly matches the REF192 pinout with active-low shutdown on Pin 3, input on Pin 2, output on Pin 6, and ground on Pin 4. Pins 1 and 5 are designated as Do Not Connect (DNC) or Test Points (TP) on both sides.Uses the identical standard 8-lead narrow SOIC footprint (0.150 inch width).All primary and safety-critical electrical parameters (accuracy, tempco, input voltage range, output drive, and temperature range) meet or exceed those of the REF192ESZ.The REF192FSZ is a drop-in replacement in the exact same SOIC-8 package and pinout configuration.It utilizes the same standard 8-lead narrow SOIC package footprint.While functionally identical with the same 2.5V output, 30 mA drive, and sleep features, it is a lower-accuracy F-grade variant with wider tolerance and drift.
AI Summary

REF192ESZ by Analog Devices: Series Voltage Reference IC Fixed 2.5V V ±0.08% 30 mA 8-SOIC.

This is a high-performance second-source series voltage reference that is fully pin-compatible and functionally superior to the REF192. It offers tighter initial accuracy, lower drift, and higher output current drive in the same SOIC-8 footprint.

  • Superior initial accuracy (±0.04% vs ±0.08%).
  • Lower temperature coefficient (3 ppm/°C vs 5 ppm/°C maximum).
  • Higher output current capability (50 mA minimum vs 30 mA maximum).
  • Slightly higher typical supply current (35 µA typical / 50 µA max vs 30 µA typical / 45 µA max).

This is a direct, same-family alternative representing the next grade down (F-grade) from the target E-grade part. It serves as an immediate drop-in replacement when the exact grade is unavailable.

  • Drop-in physical and functional replacement from the same product series.
  • Identical Pin 3 SLEEP function and active-low shutdown threshold level.
  • Identical operating temperature range (-40°C to +85°C).
  • Worse initial output voltage accuracy: ±5 mV (±0.2%) vs ±2 mV (±0.08%).
  • Higher temperature coefficient: 10 ppm/°C maximum vs 5 ppm/°C maximum.

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.
