Product details

Supply and battery backup — what to watch

Main supply range is 4.5 V to 5.5 V. The battery-backup input accepts 2.5 V to 4 V. Timekeeping current maxes at 15 mA on the main supply.

Temperature grade and environment

Rated for 0°C to 70°C commercial operation. That means it belongs in office equipment, appliances, or indoor instrumentation — not in a motor drive cabinet or an outdoor telecom enclosure. If the board sees freeze-thaw or engine-bay heat, this is not the part.

Lifecycle and sourcing posture

The DS12885+ is listed as Active with ROHS3 compliance. No end-of-life notice, no last-time-buy window. For volume production or a BOM line that needs a confirmed supply channel, this part does not carry obsolescence risk.

Frequently asked questions

Is DS12885+ a drop-in replacement for DS12887?

The DS12885+ is pin-compatible with the DS12887 and shares the same parallel interface and 24-DIP footprint. The key difference is that the DS12885+ requires an external battery on the VBAT pin, whereas the DS12887 has an integrated battery. Verify the battery circuit on your board before swapping.
