BR1632 and CR1632 share dimensions but not the complete specification

The physical envelope and nominal voltage are close, but chemistry changes from Lithium carbon monofluoride to Lithium manganese dioxide.

Use only when the device maker explicitly approves both chemistry systems.

BR1632A vs CR1632: what does the A mean?

Panasonic identifies its BR1632A as a high-temperature BR-A coin cell with 3 V nominal voltage, 16 mm diameter and 3.2 mm height. Those specifications describe that manufacturer's product; A is not a generic alias for every BR1632. Panasonic publishes a separate datasheet for its plain BR1632.

Matching the nominal size and voltage of CR1632 does not establish the same temperature rating, discharge behavior or terminal fit. Retain the complete manufacturer name, BR1632A marking and terminal suffix when checking the original part. Compare the exact manufacturer drawing, polarity and device documentation. Use a CR1632 replacement only if the device manufacturer explicitly permits it.

Why this verdict

  • The physical envelope matches.
  • Nominal voltage is close.
  • Chemistry and discharge behavior differ.

What to verify in the device

Check the original compartment label, the current manual, polarity, terminal style and whether the device explicitly permits a chemistry or rechargeable alternative.
