| FFF Compatibility | Same 24-EDIP footprint, physical dimensions, and exact pin-by-pin assignments.Same 24-pin encapsulated DIP module shape and size.Identical electrical parameters, operating voltage (4.5V to 5.5V), and 114 bytes of NV SRAM. | Same 24-EDIP footprint and pin configuration.Identical package shape and mechanical dimensions.Includes a century byte at address 32h, reducing general-purpose user NV SRAM from 114 bytes to 113 bytes. | ||
 AI Summary | DS12887 by Analog Devices: Real Time Clock (RTC) IC Clock/Calendar 114B Parallel 24-DIP Module (0.600", 15.24mm). | This is the direct lead-free/RoHS-compliant drop-in replacement for the original obsolete DS12887. It maintains exact functional, electrical, and physical compatibility without requiring any modification to the circuit.
| The DS12C887+ is a drop-in Y2K-compliant alternative from the same family. It replaces 1 byte of user RAM at address 32h with a Century register, which may require BIOS/software support or verification.

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.
Frequently asked questions
Yes. The Analog Devices DS12887 is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
The closest qualified second sources for the Analog Devices DS12887 are the DS12887+ (Analog Devices Inc./Maxim Integrated) and the DS12C887+ (Analog Devices Inc./Maxim Integrated), out of 4 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the DS12887 are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The DS12887 (Analog Devices) is a part in the Clock/Timing category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
