If you are repairing a device or salvaging a PHICO 94V-0 display, use this methodology to source the exact engineering documentation:
While specific models vary, Phico character LCDs built on the 94V-0 rated boards generally share the following baseline specifications: Electrical Characteristics Operating Voltage ( VDDcap V sub cap D cap D end-sub
: A UL certification rating for the PCB's flame retardancy, not a model identifier.

Vintage Phico LED backlights frequently require an external series resistor (typically 10 to 100 ohms) to prevent thermal runaway. Do not connect Pin 15 directly to 5V unless you confirm an onboard resistor is already present.
While exact dimensional specs can fluctuate depending on the sub-model suffix (such as the character-based DV-16100 module or the graphic WG320240C series ), the typical core engineering characteristics summarized in the Phico Datasheet PDF include: Standard Range / Specification -0.3V to +7.0V DC max (Typically operates at 5.0V ) Supply Current ( IDDcap I sub cap D cap D end-sub ) 2.0 mA to 5.0 mA Operating Temperature 0°C to +50°C Storage Temperature -20°C to +70°C Interface Options
While multiple versions exist, most Phico D-0 modules follow these general industrial standards: Power Supply : Typically requires for logic. : Standard parallel interface, often compatible with the HD44780 controller Connector Type : Varies between (standard character) and (graphics or dual-controller) configurations. Dimensions : A common 20x2 character version measures approximately 116mm x 37mm Standard 16-Pin Pinout If you are repairing a device or salvaging
This is an Underwriters Laboratories (UL) flame retardant rating. It guarantees that the device will self-extinguish within 10 seconds during a fire test. It is not a model number.
While the "D-0 94V-0" branding is found on many distinct models, the most common variants are industrial-grade character and graphic displays used in factory automation, telecommunications, and legacy computing. The Ultimate Guide To UL 94V-0 Circuit Boards - Jhdpcb
If your Phico D0 94V-0 display features a single row of 14 or 16 interface pads (either inline or arranged in a 2x8 header block), it follows the universal HD44780 pin configuration. Below is the standard mapping used across the industry: Pin Number Function Description VSScap V sub cap S cap S end-sub Ground (0V) 2 VDDcap V sub cap D cap D end-sub Power Supply (+5V or +3.3V) 3 V0cap V sub 0 While exact dimensional specs can fluctuate depending on
In terms of hardware interface, a Phico D0 series module usually features a 14-pin or 16-pin header. Pins 1 through 6 handle power and control signals—specifically Ground, VCC (usually 5V), Contrast Adjustment (V0), Register Select (RS), Read/Write (RW), and Enable (E). Pins 7 through 14 comprise the 8-bit data bus. If the module has 16 pins, the final two pins are dedicated to the LED backlight anode and cathode.
