AI Summary	LT1019ACN8-4.5 by Analog Devices: Series, Shunt Voltage Reference IC Fixed 4.5V V ±0.05% 10 mA 8-PDIP.	This is the direct lead-free (Pb-free) successor of the obsolete target part. It matches all electrical and physical parameters, allowing an immediate drop-in replacement with no design changes. Exact pin-compatible drop-in replacement Identical precision A-grade specifications (0.05% initial accuracy, 5 ppm/°C temperature coefficient) RoHS-compliant, lead-free (PBF) formulation for modern compliance	This industrial-grade sibling is designed for wider temperature ranges, though it carries the relaxed standard accuracy specification. It is a drop-in option where low-temperature or high-temperature operation is critical. Extends the operating temperature range to Industrial (-40°C to 85°C vs 0°C to 70°C) Exact physical drop-in in the same 8-pin PDIP through-hole package Relaxed initial accuracy (0.2% vs 0.05%) Higher temperature drift coefficient (20 ppm/°C vs 5 ppm/°C)

You searched one part. Parter watches your whole BOM.

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.
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.
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.
