Article Details

VL-2020/HFN is a Panasonic Energy VL-series rechargeable vanadium lithium coin cell for RTC, configuration retention, small memory backup and other controlled low-current backup rails. Selection should keep capacity, charge voltage, terminal direction, PCB footprint and enclosure clearance together instead of checking only the base cell size.

Design focus

VL-2020/HFN should be reviewed as a backup-cell component, not as a main supply or a high-pulse source. During validation, measure the real backup current after the main rail is removed and confirm that the charge path stays within the VL-series charging window.

Terminal and mounting check

The VCN and HFN suffixes identify different terminal constructions. They affect the PCB footprint, soldering process, mechanical clearance and approved purchasing line. Keep the complete suffix in drawings, RFQs and alternates.

Procurement review

For sourcing or replacement review, confirm the Panasonic brand, VL series, terminal direction, dimensions, operating temperature, datasheet revision and the target device backup-current budget. This article does not include inventory or delivery commitments; availability should be confirmed through RFQ.
