Six-cell lithium coin pack

This Panasonic BR2477A/FBN pack contains six 3 V lithium coin cells with SMD tabs. Each cell measures 24.5 mm x 7.7 mm and delivers a stable voltage for low-drain devices. The chemistry provides up to 10 years of shelf life. They suit memory-backup, real-time clock and small-sensor applications.

Tabbed SMD installation notes

The batteries arrive with pre-fitted surface-mount tabs for direct PCB soldering. No holder or adhesive is required, so assembly is a single reflow or hand-solder step. Ensure pad spacing matches the 24.5 mm diameter before ordering. Incorrect pad layout is the most common cause of rework.

BR2477A/FBN cross-reference check

The part number BR2477A/FBN appears on the label alongside equivalents such as BR2477A-FB, BR2477A/FB and P028. Verify that your board silkscreen or bill of materials lists one of these codes before fitting. A mismatched footprint will prevent proper contact.

Questions about this item

How can I confirm the 3 V lithium cells are working correctly after soldering the SMD tabs?

Measure the open-circuit voltage with a multimeter; each cell should read very close to 3 V and maintain steady output under the intended load.

What exactly is included in the 6-pack and is any additional hardware required?

The pack contains six Panasonic BR2477A/FBN coin cells measuring 24.5 mm x 7.7 mm with pre-attached SMD tabs; no extra components are needed for installation.

Which of the listed equivalent part numbers should I choose for a direct replacement?

Any of the listed equivalents — BR2477A-FB, BR2477A/FB, BR2477A/FBE, BR2477AFBN or P028 — matches the 2477 size and 3 V specification for a direct swap.
