DB09-M02 D-Sub 9-Pin Male Connector — Solder Cup for Cable Assembly
D-Sub 9 Pin Male Connector Solder Cup — Product Overview for Cable Assembly
The DB09-M02 is a D-sub 9-pin male connector with solder cup terminals, designed for cable assembly and cable-to-cable termination rather than direct PCB mounting. Unlike PCB-mount D-sub plugs where pins solder directly to board traces, the DB09-M02’s cup-style terminals are designed for wire-to-cup soldering, making it the standard choice for building custom serial cables, breakout harnesses, and field-replaceable cable assemblies.
This DB9 male solder cup connector uses the standard DE-9 (DB9) shell size with 9 contacts arranged in two rows. Each contact terminates in a hollow solder cup that accepts a stripped wire, which is then secured by soldering. This termination method is widely used in RS-232 serial cables, industrial control harnesses, and test equipment where cables are assembled in-house or in the field.
The DB09-M02 is compatible with standard D-sub hoods and backshells, allowing cable assemblers to build complete plug assemblies with strain relief, cable clamps, and shielding as required. The connector’s metal shell provides EMI shielding and mates with any standard DB9 female connector.
Manufactured in an ISO 9001:2015 certified facility, this cable mount D-sub connector is fully compliant with RoHS 3 and REACH regulations.

DB09-M02 Solder Cup D-Sub Plug — Key Features for Cable Assembly
Solder Cup Design for Flexible Wire Routing
The hollow cup terminals accept stripped wires directly, allowing cable assemblers to route wires freely without the constraints of PCB trace routing. This makes the DB09-M02 suitable for building custom cable assemblies with any wire length or routing path.
Compatible with Standard D-Sub Hoods and Backshells
The DB09-M02 uses the standard DE-9 shell size, making it compatible with the wide range of D-sub hoods, backshells, and cable clamps available from multiple suppliers. This allows assemblers to build complete cable assemblies with strain relief and shielding as required.
Field-Serviceable Termination
Solder cup terminals can be reworked in the field with a standard soldering iron. If a wire breaks or a contact fails, the connection can be re-soldered without replacing the entire cable assembly — a significant advantage for industrial equipment where downtime is costly.
30N Mating Force for Secure Cable Connections
The DB09-M02 is specified with a maximum insertion force of ≤30N and a minimum withdrawal force of ≥3.3N, providing a secure mechanical connection for cable-to-cable and cable-to-panel applications.
Metal Shell for EMI Shielding
The tin-plated steel shell provides EMI shielding for signal integrity and mates with any standard DB9 female connector. The shell also provides mechanical protection for the solder cup terminals.
RoHS 3 & REACH Compliant
Lead-free construction meets global environmental standards for unrestricted export to regulated markets.
Where to Use This D-Sub Cable Assembly Connector — Applications for Cable & Harness Assembly
As a versatile solder cup D-sub plug, the DB09-M02 is found across a wide range of cable assembly applications where wire-to-cup termination is preferred over PCB mounting or crimp termination.
DB09-M02 Solder Cup D-Sub Plug — Frequently Asked Questions
What is the difference between DB09-M01 and DB09-M02?
The DB09-M01 is a PCB-mount vertical plug designed to solder directly onto a circuit board. The DB09-M02 is a solder-cup connector designed for cable assembly — wires are soldered into the cup terminals, not onto PCB pads. Choose DB09-M01 if you’re mounting the connector on a board; choose DB09-M02 if you’re building a cable or wire harness.
What wire gauge is compatible with the DB09-M02 solder cups?
The solder cup terminals typically accommodate wire gauges from 30 AWG to 20 AWG. The maximum wire size is generally 20 AWG. For applications with larger wires or higher current requirements, confirm the specific contact rating and cup dimensions from the product datasheet.
Can I use the DB09-M02 with a standard D-sub backshell?
Yes. The DB09-M02 uses the standard DE-9 shell size and is compatible with the wide range of D-sub hoods, backshells, and cable clamps available from multiple suppliers. This allows you to build complete cable assemblies with strain relief, cable clamps, and shielding as required.
Is the DB09-M02 suitable for field repair?
Yes. Solder cup terminals are field-serviceable — if a wire breaks or a contact fails, the connection can be re-soldered with a standard soldering iron without replacing the entire cable assembly. This is particularly useful for industrial equipment where downtime is costly.
What is the current rating of the DB09-M02?
The DB09-M02 is rated for 5A per contact at 250V AC. The actual current capacity depends on the wire gauge, ambient temperature, and the number of simultaneously energized contacts.
What is the MOQ and can I get a free sample?
Standard MOQ is 1,000 pieces with a 2–4 week production lead time. Free samples are available for qualified engineering and product development projects. Contact sales@vistarelectronics.com with your company details, project description, and part number (DB09-M02).
