【Product Overview】DC-039 5.1×1.65mm Through-Hole DIP Fully Encapsulated DC Power Jack

DC-039(Engineering drawing, also known as DC00390 / DC0039B) is specifically designed for hardware interfaces with high mechanical strength and high stability. DIP through-hole DC power jack (female connector). This product precisely fits power adapter male plugs with an outer diameter of 5.1mmand a center pin diameter of 1.65mm The power adapter male connector (compatible with plugs of outer diameter 4.0mm / 4.75mm and inner diameter 1.75mm) fully meets the assembly standards for industrial and consumer-grade hardware interfaces.

DC-039 adopts a high-strength engineering plastic fully sealed box structure, with precise and regular external dimensions (body width 9.0mm × length 13.0mm × height 10.0mm). The front of the socket features a 2.6mm deep panel positioning slot, which perfectly fits with the front frame of the device housing. The bottom is equipped with a φ1.8mm PCB positioning post and bent straight-through reinforcing pins (2.0×0.8mm and 2.5×1.2mm), which, after wave soldering or hand soldering, can significantly disperse the shear and tensile stresses generated during insertion and extraction.

[Expert-Level B-Side Selling Points and B2B Procurement Decision Factors]

1. 5.1×1.65mm precise specification, high conduction reliability

The center pin is 1.65mm in diameter as standard specification, with internal contact springs that provide lasting elasticity and fit tightly with the male connector, effectively preventing device power loss caused by poor contact or vibration.

2. Front housing slot design, easy for overall device structure assembly

The front of the body features a stepped positioning slot that prevents warping and wobbling when embedded into the device housing, achieving a highly flat and seamless connection between the interface and the panel.

3. PCB positioning posts + bent reinforced solder legs, strong mechanical pull-out resistance

The bottom is designed with dedicated positioning posts and bent pins, forming a stable triangular support structure on the PCB, significantly enhancing the solder joint's resistance to insertion/withdrawal fatigue and peel strength.

4. Compatible with both wave soldering and manual soldering processes

The pins are made of high-quality, easily solderable copper alloy with tin plating on the surface, offering good temperature resistance. They are suitable for automated wave soldering lines for mass production as well as convenient for manual soldering and repair.
