3V lithium coin cells with PCB pins

This three-pack supplies Panasonic BR2477A/HBN lithium coin cells rated at 3 volts. Each cell measures 24.5 mm by 7.7 mm and uses a horizontal PC pin termination for direct board mounting. The chemistry delivers high energy density and a continuous voltage supply suited to memory-backup and real-time-clock circuits. Shelf life reaches up to 10 years when stored correctly.

Drop-in replacement for BR2477 variants

The pins match the BR-2477A/HB, BR2477A-HB, BR2477A/HB, BR2477A/HBE, BR2477AHBN and P029 equivalents, so existing layouts need no redesign. A swap is worthwhile when the original cells show voltage sag under load or have exceeded their storage window. The 10-year shelf rating also makes the pack practical for service spares.

For board-level maintenance and low-drain designs

Engineers maintaining legacy motherboards, utility meters or industrial controllers will find the pin format ready to solder. Buyers who need a button-top cell for a holder or a higher-capacity chemistry should look at a different form factor.

Questions about this item

Will the 24.5 mm diameter and 7.7 mm height fit my board?

The cell measures 24.5 mm across and 7.7 mm thick, so verify your holder accepts those exact dimensions before ordering.

How do I solder the horizontal PC pins without damaging the lithium chemistry?

Apply heat briefly to each pin pad; prolonged iron contact can degrade the seal and reduce the 10-year shelf life.

When should I replace the three cells in a memory-backup application?

Plan replacement after ten years or when the voltage drops below 3 V, whichever occurs first.
