VL-2330/VCN Panasonic rechargeable coin cell is a 3V VL-series vanadium lithium backup battery for low-current memory, clock and configuration-retention rails. Panasonic lists the VL2330 family with 50.0 mAh nominal capacity, 23.0 mm diameter, 3.0 mm height and a 3.25-3.55V charging-voltage window. The VL-2330/VCN suffix identifies a vertical PC pin terminal version, so the part must be selected as both an electrochemical cell and a PCB-mounted mechanical component.

What is VL-2330/VCN?

VL-2330/VCN is a Panasonic Energy VL-series coin-type rechargeable lithium battery. In practical design language, it is a soldered backup cell for a small always-on domain, not a removable consumer coin cell and not a main power source. It is normally placed on a board section that must retain state when the main supply is removed, such as a real-time clock, SRAM domain, secure state memory, meter module, industrial controller, gateway or portable instrument.

The Panasonic product page and datasheet should be treated as the first reference for VL2330 electrical limits, while the terminal drawing must be checked for the exact vertical PC pin footprint.

How VL-2330/VCN is used

Typical circuit role

In a typical system, VL-2330/VCN sits behind a controlled charging path from the main 3.3V or regulated backup rail. During normal operation, the cell is maintained near the specified charge-voltage window. When the main supply is lost, the backup domain is isolated from the rest of the system and the cell supplies only the load that truly needs retention. That load is usually measured in microamps, not tens of milliamps. The designer should calculate backup time from the real leakage and retention current, not from a broad product-family assumption.

The charging path is one of the most important design checks. Panasonic's VL charging guidance uses a 3.4V center value with a 3.4V +/-0.15V guaranteed range across -20 to +60°C, and the company warns against trickle charging. The design should not rely on a vague leakage path, an unreviewed diode drop or a rail that can rise near 4V. Regulator tolerance, resistor tolerance, temperature drift, brownout behavior and reverse-current paths all affect the cell.

Terminal and pinout considerations

The suffix is not a minor purchasing detail. Panasonic's terminal line-up identifies VL-2330/VCN as an available terminal version, and distributor listings describe this version as PC pins for vertical PCB mounting. That means the VL-2330/VCN pinout is mainly a mechanical/polarity question: which tab connects to which board pad, how the cell body clears the enclosure, and how soldering stress is handled. The positive case, negative terminal, solder land geometry, terminal pitch and insertion direction should be checked from the terminal drawing before PCB release.

For this specific version, the mounting logic is higher-capacity upright backup cell with smaller board footprint and greater height keep-out. That affects component placement around shields, displays, coin-cell keep-outs, service covers and automated assembly. If a purchasing team substitutes a different suffix after layout release, the electrical family may still look right while the board becomes impossible to assemble.

Key specifications for VL-2330/VCN

VL-2330/VCN selection guide

Select VL-2330/VCN when the design needs a soldered rechargeable 3V backup cell, the backup current is low, the charging rail can be kept inside the VL window, and the PCB can accept the vertical PC pin terminal geometry. It is a reasonable candidate for RTC backup, register retention, small memory domains, metering boards, industrial controls, communication modules and other systems that spend most of their life powered but need controlled state retention during outages.

Do not select VL-2330/VCN only because the voltage matches a familiar primary coin cell. A VL rechargeable cell should not be treated like a CR or BR primary cell. It also should not be used as a high-pulse source for radios, motors, relays, alarms or main system loads. If the product needs longer backup time than the 50.0 mAh class can support, review a larger VL family such as VL2330 or another approved energy-storage approach. If the product has compact enclosures that cannot accept a 23.0 mm diameter cell or an upright mounted battery, review the other terminal suffix or a different mechanical layout before approving the BOM.

The selection checkpoint is straightforward: measure retention current, define backup duration, calculate capacity margin, confirm the charge circuit across tolerance and temperature, then freeze the full part number including suffix. A sourcing request that says only VL2330 is incomplete; it should name VL-2330/VCN and state the terminal option, packaging request, application risk and acceptable substitute range.

Alternatives and cross references for VL-2330/VCN

Possible alternatives can be useful during sourcing, but they are not automatic replacements. Before approving a VL-2330/VCN replacement, compare the datasheet, terminal pinout, package outline, PCB footprint, charge voltage, charge current, discharge current, capacity, temperature range, safety certifications, lifecycle status and transport requirements. A different suffix may be electrically similar and still fail mechanically.

Buying notes and sourcing checks

Before issuing an RFQ for VL-2330/VCN, confirm the full manufacturer part number, Panasonic brand wording, terminal suffix, package or bulk handling method, date code expectations, batch consistency, original factory condition, certificate requirements, delivery schedule and acceptable alternatives. For safety-sensitive or regulated equipment, confirm whether IEC 62133-2, UL 1642, RoHS, REACH, transport documentation or customer-specific approval records are required for the build.

Also confirm the application risk before accepting a substitute. A substitute that changes the terminal angle can force a PCB change; a substitute that changes the chemistry can force a charge-circuit change; a substitute that changes capacity can shorten the retention window.

VL-2330/VCN FAQ

Where can I find the VL-2330/VCN datasheet?

The base-cell data should be checked in the Panasonic VL2330 datasheet. The terminal suffix should also be checked against Panasonic terminal information or supplier documentation before PCB release.

What is the VL-2330/VCN pinout?

For a rechargeable coin cell, pinout means terminal polarity and tab geometry. VL-2330/VCN uses PC pins for vertical PCB mounting; exact pad spacing and terminal dimensions should be confirmed from the terminal drawing.

What applications fit Panasonic VL-2330/VCN?

Typical applications include RTC backup, memory retention, meter backup, communication modules, industrial controllers and low-current backup domains that can use a controlled VL charging circuit.

Can VL-2330/VCN replace a CR2032 or BR coin cell?

Not directly. CR and BR cells are primary batteries, while the Panasonic VL series is rechargeable and needs the correct charge-control conditions. A circuit-level review is required.

Can I use another VL suffix instead of VL-2330/VCN?

Only after checking the PCB footprint, terminal direction, enclosure clearance, polarity, soldering process and approved vendor list. VCN and HFN suffixes solve different mechanical problems.

What should procurement confirm before buying VL-2330/VCN?

Confirm the complete part number, Panasonic brand, terminal suffix, packaging, date code, batch requirement, original condition, certification needs, delivery schedule and accepted substitute range.
