SR527SW equivalents

Direct replacements

The same cell under another code. Any of these fits, whatever the brand.

  • 319
  • SR64
  • SR527

Upgrade or downgrade

Same size, different chemistry. Read the verdict before you buy.

Cell Chemistry Voltage Verdict
LR527 alkaline 1.5 V Downgrade Works, but runs out sooner. Avoid in watches and medical devices.

Similar size, check the fit

Same diameter, different thickness. These are not drop-in replacements.

Cell Size Verdict
SR512 5.8 × 1.2 mm Same 5.8 mm diameter, but 1.2 mm tall instead of 2.7 mm. Only if the holder fits; thinner cells can lose contact.
SR516SW 5.8 × 1.6 mm Same 5.8 mm diameter, but 1.6 mm tall instead of 2.7 mm. Only if the holder fits; thinner cells can lose contact.
SR521SW 5.8 × 2.1 mm Same 5.8 mm diameter, but 2.1 mm tall instead of 2.7 mm. Only if the holder fits; thinner cells can lose contact.
