DC Jack Socket Connector Pack

This pack contains five straight blade DC jack sockets rated for 2.1mm by 5.5mm centre-positive plugs. Each unit has two terminals and mounts vertically on a printed circuit board. The metal and plastic housings measure 16mm by 10mm and finish in black with silver tone contacts. The connectors serve as direct replacements in media players, portable audio devices, notebooks, smartphones and car audio systems.

Hobbyists repairing consumer audio gear

Technicians servicing MP3 players, portable media players or notebook power inputs will find the vertical PCB footprint and 2.1mm by 5.5mm barrel size a direct match. Builders needing surface-mount jacks, right-angle orientation, locking barrels or a different inner pin diameter should source a different connector type.

2.1mm by 5.5mm barrel with vertical PCB mount

The critical specification is the 2.1mm inner diameter paired with a 5.5mm outer sleeve on a vertical through-hole footprint. Confirm the existing board uses this exact barrel geometry and pin spacing before ordering, as mismatched dimensions will prevent a secure fit.

Questions about this item

Should I choose the 2.1mm or 5.5mm version for my device?

This is a single part with a 2.1mm centre pin and a 5.5mm outer barrel; match both dimensions to your equipment.

What does the 2.1mm x 5.5mm size mean when I solder it to a board?

The 2.1mm centre pin and 5.5mm barrel accept standard coaxial power plugs; the 16 x 10 mm body fits the PCB footprint.

How does the PCB-mount interface limit the current I can run through it?

Two metal terminals carry the current; the connector is rated for typical low-voltage DC power applications.
