Product Description: DC-031A Surface Mount Right Angle DC Power Jack

The DC-031A is a high-performance, surface-mount DC power jack engineered for reliable power connectivity in space-constrained applications. This male connector features a compact 3.5 mm x 1.0 mm bushing specification, with a precise center pin outer diameter (OD) of 1.0 mm, ensuring a secure fit with standard 3.5 mm OD / 1.0 mm ID male plugs. Designed as a right-angle configuration, the DC-031A facilitates low-profile PCB mounting, making it ideal for compact devices where horizontal plug insertion is required.

This component offers three conductors, providing robust switching functionality for sophisticated power management. It is rated for 24V DC at 2.0 amps, delivering a dependable power supply solution suitable for a wide range of portable electronics, including medical devices, handheld instrumentation, networking peripherals, and consumer audio equipment. The surface-mount design ensures efficient automated assembly processes, reducing manufacturing costs while improving solder joint consistency. The connector’s insulation housing is molded from high-performance PPA (Polypthalamide), offering superior thermal stability, low moisture absorption, and excellent dielectric strength, making it well-suited for reflow soldering processes and demanding operating environments.

Critically, the DC-031A shares identical dimensions, mechanical drawings, and electrical specifications with the Same Sky (formerly CUI Devices) PJ-035-SMT-TR connector. As a result, the DC-031A serves as an excellent, form-fit-function alternative to the PJ-035-SMT-TR. Engineers and procurement specialists can confidently substitute this part without requiring PCB layout revisions or worrying about performance degradation.

The connector’s right-angle orientation maintains a low installed height above the board, optimizing internal space utilization. Whether used for prototyping or high-volume production, the DC-031A combines proven mechanical compatibility with reliable 24V/2A power handling, making it the smart choice for seamless replacement or new designs requiring a trusted power interface.
