Number of pins
9-pin and 15-pin D-sub connector versions are listed. Check rows, density and shell size as well, because 15 positions can mean two different inserts.

How to select
Selecting a D-sub connector for a PCB in four steps
A D-sub connector on a circuit board is fixed by its mating face first and its footprint second. Settle positions, density and gender, then the board layout, the ratings and finally a sample.
- 01
Define the mating interface
Confirm 9 or 15 positions, standard or high density, gender and the mating shell. A DB9 connector on the board has to match the shell size and gender of the cable plug.
- 02
Review the PCB layout
From the D-sub connector drawing, confirm right angle or vertical orientation, hole pattern, board locks and board-edge spacing before routing.
- 03
Separate ratings from pin assignment
Check the part ratings (3 A or 5 A, 1000 V AC withstand), then take signal and ground assignment from the equipment circuit, not from the shell.
- 04
Validate and move to sourcing
Fit D-sub connector samples to the board and mating cable in a new design, or request pricing directly once the part number is fixed.
Key selection parameters
D-sub connector parameters: positions, gender and mounting
Fields come from the current PCB mount D-sub records. Read every rating together with its test condition in the datasheet.
Model type and gender
Every listed part is a female D-sub socket. Confirm gender from the drawing and check the mating plug shell and its hardware.
Mounting angle
90 degree D-sub connectors mount at a right angle with the mating face at the board edge; the 180 degree part is vertical. Confirm the view in the drawing.
Rated current
Each D-sub connector is rated 3 A or 5 A. Check the load per contact, how many contacts carry current at once, temperature rise and ambient conditions.
Withstand voltage and life
1000 V AC withstand and 500 plug and unplug cycles are listed across the D-sub connector range. Withstand voltage is a test value, not a working voltage.
Product family comparison
D-sub connector ratings: 3 A and 5 A versions
The D-sub connector range splits by rated current: 3 A parts in 9-pin and 15-pin, 90 and 180 degree versions, and a 5 A 9-pin right angle part. Confirm each value in the individual part row.

Where a D-sub PCB connector still fits the design
D-sub connectors remain common on industrial controllers and instruments because the shell and screw-lock hardware hold a cable firmly. Check the protocol, the grounding and the service access against the drawing.
Industrial control board I/O
- Read the D-sub connector drawing together with the equipment signal assignment
- Do not infer RS-232, RS-485 or CAN from the shell
- Plan board locks and jackscrew nuts before the panel is fixed
Equipment service and peripheral ports
- Review plug retention and jackscrew access
- Tie the D-sub connector shell to chassis where the cable screen terminates
- Leave finger room for the thumbscrews on the cable plug
Replacing an existing D-subminiature connector
- Compare footprint, board-edge position and shell projection
- Match board lock and nut type, not only contact count
- Validate replacement D-sub connector samples on the existing PCB before release

Category overview
D-sub connector naming, density and the hardware that fits
Two D-sub parts can share a contact count and a shell size and still not be interchangeable.
The DB9 naming is a misnomer
In the original designation the letter gives the shell size and the number gives the contact count, so a nine-way connector in an E-size shell is properly a DE-9 connector. Common usage settled on DB9 regardless, and many drawings still call the same part a DB9 connector. Where it matters, specify shell size and contact count separately rather than relying on the popular name.
The same applies to fifteen positions. A standard two-row 15-pin D-sub uses the A shell (DA-15, often sold as a DB15 connector), while the three-row version fits the E shell. Read the row count from the drawing before choosing a mating cable.
Standard or high density
A high density D-sub fits more contacts into the same shell by using three rows and a finer pitch, which is how fifteen contacts fit an E shell. The shells are mechanically similar but the inserts are not, so a standard and a high-density part of the same size will not mate with each other.
On this page the 15-position parts are listed by pin count only, so check the drawing to see whether a given D-sub connector uses the standard or the high density layout.
Mounting hardware decides the fit
Board lock style, rivet or harpoon retention, the footprint dimension and the jackscrew nut size all vary between otherwise similar parts. These are what stop a substitution from fitting, far more often than the electrical rating does. Read them off the drawing before treating two parts as equivalent.
For a D-sub connector PCB mount, also check the distance from the board edge to the mating face and the shell flange. A right angle D-sub connector usually overhangs the board edge, so the panel cutout and the board outline have to be drawn together.
FAQ & related guides
DB9 connector and D-sub connector questions before layout
Answers on naming, pinout, orientation, footprints and ratings. Limits for each D-sub connector part number come from its own datasheet.
What is the difference between D-sub and DB9?
D-sub, short for D-subminiature, names the connector family. DB9 connector is the everyday name for the 9-position version, which is strictly a DE-9 by shell size. Specify gender, mounting style and mating dimensions as well as the name.
Is every 15-pin D-sub a VGA connector?
No. Fifteen-position parts come in standard two-row and high-density three-row layouts with different shells, and VGA also fixes the signal assignment. Equal contact count does not establish mechanical or electrical compatibility.
Where do I find the pinout for a 9-pin D-sub?
Use the connector drawing for contact numbering, viewing direction and PCB termination positions. Take RS-232, CAN or other signal assignments from the equipment or application circuit, not from the D-sub connector itself.
Should I use a right angle D-sub or a vertical one?
Choose by the mating axis relative to the PCB and panel: right angle when the cable leaves parallel to the board, vertical when it leaves away from it. Then check the drawing view and mounting holes, and ask us if a part title and its orientation field disagree.
What should a DB9 connector PCB footprint include?
Contact holes, board lock or retention holes, shell tabs and the keep-out under the flange, all taken from the selected part drawing. Do not reuse another brand's footprint on contact count alone; terminal positions, hole sizes and screw positions can differ.
Can every D-sub connector contact carry the full rated current?
Do not infer that from one figure. Listed ratings are 3 A or 5 A; check ambient temperature, conductor size, how many contacts are loaded at once and the temperature-rise limit against the specification and your own validation.
Does a metal D-sub shell guarantee shielding?
A D-sub connector shell is one part of the shielding path. Review contact with the mating shell, the PCB or chassis connection, cable-shield termination and grounding, then validate the complete equipment.
How do I request D-sub samples, pricing or a replacement assessment?
For a known part, send its number and quantity. For a replacement, include the existing datasheet, mating plug and the fixed PCB and panel dimensions. Early projects can start from the interface requirement alone.
