CR2050W
3V lithium coin cell
CR2050W is a 3V lithium coin cell used when an OEM names the Murata / wide-temp CR2050W pack — for example TE Connectivity U5601 battery option 3. Same ~20×5 mm family as CR2050, but treat the W suffix as a typed option. Not a drop-in for CR2032.

Rechargeables are not equivalents
Rechargeable coin cells (LIR, ML, VL, CTL and similar) are not drop-in replacements for disposable CR cells — voltage and charging requirements differ. Same size does not mean the same battery.

Notes
Wide-temperature / OEM variant of the CR2050 size family (e.g. Murata CR2050W on TE/Althen U5601 battery option 3). Not an automatic alias for plain CR2050 — match the OEM pack label and model battery option.
