DB15 Male Connector – 15 Pin Vertical PCB Mount D-Sub

Below are the complete specifications for the DB15 PCB connector DB15-M03, covering electrical, mechanical, and environmental ratings.

Specifications should be verified against the latest product drawing and engineering documentation before production release. Electrical performance depends on the complete system design, including cable assembly, termination, and application environment.

A right angle DB15 connector mounts parallel to the PCB surface, making it suitable for side-entry I/O applications in industrial controllers, HMI panels, embedded computers, and test instruments where vertical space is limited. The DB15-M03’s right angle orientation positions the connector parallel to the board, optimizing internal layout while providing a secure mating interface for standard DB15 female counterparts.

Advantages of Right Angle PCB Mounting

• Space efficiency: The connector mounts parallel to the PCB surface, reducing vertical height requirements in compact enclosures.
• Side-entry design: Ideal for applications where cables need to enter from the side of the equipment rather than from the rear.
• Panel integration: Suitable for industrial controllers, HMI panels, embedded computers, and test equipment with side-panel I/O.
• Through-hole strength: External insertion and withdrawal create mechanical stress — through-hole DIP soldering provides stronger PCB mechanical retention than SMT alternatives.

When designing with a right angle DB15 connector, engineers should consider the PCB edge clearance, connector alignment with the enclosure opening, and mechanical support for the shell grounding tabs. The DIP through-hole design requires appropriate PCB thickness and hole diameter for reliable solder joint formation.

One of the most common questions about 15 pin D-sub connectors is whether a standard DB15 and an HD15 (DE15) VGA connector are interchangeable. The short answer is no — they are different connector families with different mechanical and electrical characteristics.

A standard DB15 male connector and an HD15 VGA connector should not be treated as interchangeable simply because both have 15 contacts. The shell size and contact spacing are different, and they are mechanically incompatible. Always verify the connector specification against the equipment schematic or cable specification before selecting a 15-pin D-Sub connector.

The physical 15 pin D-sub connector provides 15 contact positions arranged in three rows of five pins. The contact assignment follows the standard D-Sub pin numbering convention, with pins arranged in alternating rows.

The electrical pin assignment is application-dependent. The same physical 15-pin D-Sub connector can have completely different pin assignments depending on the application — industrial control, legacy AUI interfaces, or other proprietary systems. Always verify the equipment schematic or cable specification before wiring a DB15 male connector.

For detailed pinout information specific to your application, refer to the equipment documentation or system specification. The physical connector provides the interface; the signal assignment is determined by the system design.

Understanding the difference between male and female D-Sub connectors is essential for correct system design and cable assembly.

The DB15-M03 is the male side of the DB15 mating interface. For PCB applications requiring the female counterpart, see our DB15 female connector options.

What Is a DB15 Male Connector?

A DB15 male connector is a 15-pin D-Sub connector with male contacts (pins). The DB15-M03 is a right angle DIP PCB mount version with through-hole termination, rated for 5A and suitable for industrial, communication, and test equipment applications. The connector features a nickel-plated steel shell for EMI shielding and copper alloy contacts with gold plating for reliable signal integrity.

D-Sub connectors, including the DB15 PCB connector, are widely used in industrial automation, communication equipment, test and measurement, and embedded systems. The right angle PCB mount design allows for efficient board space utilization in side-entry applications while providing strong mechanical retention through DIP through-hole termination.

DB15 vs HD15 — Understanding the Difference

One of the most common questions about 15 pin D-sub connectors is whether a standard DB15 and an HD15 (DE15) VGA connector are interchangeable. The short answer is no — they are different connector families with different mechanical and electrical characteristics. A standard DB15 male connector and an HD15 VGA connector should not be treated as interchangeable simply because both have 15 contacts. The shell size and contact spacing are different, and they are mechanically incompatible.

For engineers working with legacy interfaces or industrial equipment, understanding this distinction is critical to avoid connector compatibility issues. Always verify the connector specification against the equipment documentation before selecting a 15-pin D-Sub connector.

DB15 Male vs Female — Choosing the Right Gender

When designing a system that uses DB15 male connectors, understanding the difference between male and female D-Sub connectors is essential. Male connectors have pins and are typically used on cables or as the plug side of the interface. Female connectors have sockets and are typically used on PCBs or as the receptacle side. The DB15-M03 is a male connector designed for PCB mounting, making it suitable for equipment that requires a male interface on the board.

Right Angle PCB Mounting for Industrial Applications

A right angle DB15 connector mounts parallel to the PCB surface, making it suitable for side-entry I/O applications in industrial controllers, HMI panels, embedded computers, and test instruments where vertical space is limited. The DIP through-hole design provides superior mechanical retention compared to SMT alternatives — critical for connectors that experience repeated cable insertion and withdrawal.

The right angle orientation allows for efficient board space utilization in compact enclosures, making it ideal for space-constrained applications. When designing with a right angle DB15 connector, engineers should consider the PCB edge clearance, connector alignment with the enclosure opening, and mechanical support for the shell grounding tabs.

Applications Across Industries

This 15 pin D-sub male connector is widely used across multiple industries. Industrial automation uses it for PLC equipment, industrial controllers, HMI systems, and machine control interfaces. Communication equipment uses it for data communication devices, serial interface systems, and network hardware. Test and measurement applications include test equipment, measurement systems, and laboratory instruments. Computer peripherals, embedded systems, and legacy equipment replacement also rely on the DB15-M03 for reliable multi-pin connectivity.
