Definition of DB-15

DB-15 is a type of D-subminiature connector with 15 pins, arranged in two parallel rows. It is commonly used as a video interface for connecting analog VGA monitors to computers and other devices. Though it has been largely replaced by digital interfaces like HDMI and DisplayPort, the DB-15 connector remains a widely recognized and utilized standard in the technology world.


D is pronounced as “Delta” in the International Phonetic Alphabet (IPA) and B is pronounced as “Bravo.” Numbers are spoken as they are: 1 as “One” and 5 as “Five.” So, the phonetics of “DB-15” would be “Delta Bravo – One Five.”

Key Takeaways

  1. DB-15 is a common type of D-sub connector, featuring 15 pins arranged in two rows.
  2. It is often used for connecting analog VGA monitors to computers and other video display systems.
  3. Despite being largely replaced by newer interfaces like HDMI and DisplayPort, the DB-15 connector remains popular for its backwards compatibility and widespread availability.

Importance of DB-15

The technology term “DB-15” is important because it refers to a specific type of D-subminiature connector widely used in various electronic devices for data and signal transfer.

With 15 pins arranged in two rows, the DB-15 connector offers a compact and reliable connection interface.

While it gained popularity as a standard connector for VGA graphic display ports, it has since been utilized for other purposes, such as in game controllers and network equipment.

The versatility, reliability, and compact design of the DB-15 connector contribute to its ongoing significance in the tech industry.


The DB-15 connector, with its unique trapezoidal shape and fifteen pins, has been widely employed in devices that necessitate high-quality audio/video transmission, including computing and gaming. Initially, the DB-15 connector was utilized in analog video connections as a part of the Video Graphics Array (VGA) standard, which was introduced in 1987.

With VGA graphics cards, DB-15 facilitated the transfer of analog video signals between computer systems and CRT display devices – this allowed users to experience resolution up to 640×480 pixels for tasks such as gaming, or running graphical applications. Accordingly, one of the connector’s main purposes was to streamline the connection process, ensuring seamless transmission between source and display.

With the advent of newer technologies, such as high-definition digital video signals and HDMI connections, the DB-15 connector has seen a decline in usage and popularity, particularly in video applications. However, it has found a new purpose in other fields, such as device control and interfacing: it has been adopted for multi-pin connections within robotics and industrial automation, allowing easy device management and information transfer between multiple control units.

Effectively, DB-15 has remained versatile with evolving technology trends and continues to play a critical role in applications requiring robust signal transmission.

Examples of DB-15

The DB-15 connector, also known as a D-sub 15 or DA-15 connector, is a 15-pin analog connector often used for various computer and electrical applications. Here are three real-world examples where the DB-15 connector is commonly utilized:

VGA Connection: DB-15 connectors are widely used for video graphics array (VGA) connections in computer systems. VGA is an analog video display standard that was popular during the early days of personal computers (PCs) and became the main display standard for PCs until digital display connections such as HDMI and DisplayPort became prevalent. DB-15 connectors were used to connect display devices such as monitors, projectors, and other video output devices to a compatible VGA port on a computer or laptop.

Gameport Interface: The DB-15 connector was used in older gaming consoles and PCs as a gameport interface. This interface allowed users to connect gaming peripherals such as joysticks, game controllers, and flight simulators to their computer systems. The gameport was eventually replaced by newer connection technologies, such as USB, which provided a more streamlined and flexible interface for peripheral connectivity.

Industrial and Medical Equipment: The DB-15 connector has been used in various industrial and medical equipment applications due to its compact size and robustness. For example, the connector may be used to connect sensors and monitoring equipment in manufacturing facilities, or to link monitoring systems in a clinical or hospital setting. In these contexts, the connector enables the transfer of important data and signals between devices and equipment.

FAQs about DB-15

1. What is a DB-15 connector?

A DB-15 connector, also known as a D-sub or VGA connector, is a 15-pin connection standard that is commonly used in video and data connections. It was widely used for connecting computers with monitors, projectors, and other video devices.

2. What are the typical uses of a DB-15 connector?

DB-15 connectors are mainly used in video applications, such as connecting a computer to a monitor or a projector. However, they can also be used for other data connections, including serial and joystick connections.

3. How is a DB-15 connector different from the other D-sub connectors?

The main difference between a DB-15 and other D-sub connectors lies in the number of pins: DB-15 has 15 pins, while other D-sub connectors, such as DB-9 and DB-25, have 9 and 25 pins respectively. The differences in pin numbers dictate the data and signal carrying capacity, with DB-15 mostly used for video and data connections.

4. Are there any alternatives to the DB-15 connector?

Yes, there are several alternatives to the DB-15 connector, including HDMI, DisplayPort, and DVI connectors. These alternatives offer improved video quality, greater data transfer speeds, and smaller form factors, making them more suitable for modern video applications.

5. Can I convert a DB-15 connector to other video connector types?

Yes, you can use a simple adapter or converter cable to convert a DB-15 connector to other video connector types, such as HDMI, DVI, or DisplayPort. Note that these conversions may not provide the same high-quality video performance as a native connection using the target video connector type.
