Vertical D-Sub 25 Pin Male Connector – DB25-M01, PCB Mount Solder Type

The DB25-M01 is a vertical D-sub connector 25 pin — a male plug with solder-type PCB terminals and a straight (vertical) orientation. The connector mounts upright on the PCB, with the D-shaped mating face pointing away from the board surface. This orientation is suitable for rear-panel I/O where the mating cable enters perpendicular to the PCB, and for equipment that uses a DB25 interface for serial, parallel, or multi-channel analog signal transmission.

This DB25 male PCB mount connector uses the standard DB25 shell size with 25 contacts arranged in two rows. The solder-type terminals are designed for through-hole PCB soldering, providing a mechanically robust connection between the connector and the board. The tin-plated steel shell provides EMI shielding and mates with any standard DB25 female connector.

As a 25 pin D-sub plug solder connector, the DB25-M01 is commonly used in industrial control panels, CNC equipment, test and measurement instruments, printers, and legacy system replacements where a reliable board-level DB25 interface is required. The vertical orientation helps save board-edge space compared with right-angle alternatives, and simplifies enclosure design when the cable is routed from the rear of the equipment.

Manufactured in an ISO 9001:2015 certified facility, this D-sub 25 pin male connector is fully compliant with RoHS 3 and REACH regulations. The product page had a minor spelling error (“Nomuber” should be “Number”) that has been corrected in the specification table below.

Below are the published specifications for the DB25 connector vertical DB25-M01. Values marked “Refer to Datasheet” require confirmation against the current Vistar engineering drawing before production release.

Electrical and mechanical values shown are representative industry ranges for standard DB25 PCB mount connectors. Final specifications for DB25-M01 are subject to Vistar’s current datasheet.

What Is a Vertical D-Sub Connector 25 Pin?

A vertical D-sub connector 25 pin is a DB25 male plug that mounts upright on a PCB, with the D-shaped mating face pointing perpendicular to the board surface. The DB25-M01 is a solder-type PCB-mount version designed for through-hole soldering. This orientation is suitable for rear-panel I/O, where the cable enters from behind the equipment rather than from the side. The connector uses the standard DB25 shell size and 25-contact arrangement, ensuring compatibility with standard DB25 female connectors and cables.

DB25 Male PCB Mount — Through-Hole Soldering and Mechanical Reliability

The DB25 male PCB mount configuration uses through-hole solder terminals that pass through the PCB and are soldered on the opposite side. This creates a mechanically robust connection between the connector and the board — important for DB25 interfaces that may experience repeated cable insertion and removal, or that are installed in equipment subject to vibration. The tin-plated steel shell provides EMI shielding and mates with any standard DB25 female connector. For a broader comparison of D-sub mounting styles, see the D-Sub Connector Guide.

25 Pin D-Sub Plug Solder — Interface Standards and Pin Definitions

The 25 pin D-sub plug solder interface follows the standard D-subminiature shell dimensions. The DB25 connector is standardized under IEC 60807 and MIL-DTL-24308, which define the mechanical and performance requirements for D-subminiature connectors. However, the pin assignment for a DB25 connector is application-dependent — RS-232 serial, parallel port, and professional audio multi-channel all use the same physical connector with different signal definitions. Engineers should always confirm the pinout against the equipment schematic or the relevant standard before PCB layout. Vistar’s D-Sub Pin Definitions Guide provides a reference for common pin assignments.

DB25 Connector Vertical — Applications in Industrial and Legacy Systems

The DB25 connector vertical is found across industrial control panels, CNC equipment, test and measurement instruments, printers, and legacy system replacements. In industrial automation, DB25 connectors are used for machine control interfaces, data acquisition, and communication links. In test equipment, they provide a reliable board-level interface for signal routing and diagnostics. In legacy systems, the DB25-M01 serves as a replacement part for equipment where the original connector has failed or become unreliable.

D-Sub 25 Pin Male — Selection and Procurement Considerations

When selecting a D-sub 25 pin male connector for production, procurement teams should confirm the contact plating (gold or tin), the required current and voltage rating, the operating temperature range, and the PCB mounting hardware (board locks or mounting posts). The DB25-M01 is supplied in bag or tray packaging. For volume orders, confirm the MOQ, lead time, and whether a mating female connector or cable assembly is required. The connector should be tested with the actual mating female connector before mass production to confirm insertion and withdrawal forces.
