AI Summary

LT1021BCN8-5 by Analog Devices: Series, Buried Zener Voltage Reference IC Fixed 5V V ±1% 10 mA 8-PDIP.

The LT1236 is a drop-in sibling of the LT1021 series. The A-grade variant matches the 5 ppm/°C max drift and high accuracy of the original B-grade LT1021, and its internal connections on pins 1, 3, 7, and 8 allow a seamless physical drop-in.

  • Extremely high precision with ±0.05% initial tolerance matching the LT1021B baseline
  • Maintains the identical ultralow temperature coefficient of 5 ppm/°C max drift
  • Same 8-PDIP through-hole footprint and pin assignments, including internally connected DNC pins on 1, 3, 7, and 8

This is the direct lead-free (RoHS compliant) counterpart of the original part. It is actively produced and has identical electrical characteristics and physical dimensions, serving as the ideal drop-in replacement.

  • Exact direct drop-in replacement with identical electrical and physical specifications
  • Lead-free (RoHS compliant) variant of the original obsolete part
  • Maintains the same ultralow 5 ppm/°C maximum drift rate and ±0.05% initial tolerance

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.
