I-PEX 82907-100B-02-D is a 50Pin ultra-thin coaxial cable assembly from the CABLINE®-UX II series, corresponding to the Micro-Coaxial, 46AWG, 100mm, 1-N configuration in official documentation. The connector model used at the cable end is 20532-050T-02-1. CABLINE®-UX II features a 0.25mm Pitch, 90° out-line vertical plug-and-play structure, with a height of about 1.04mm, depth of about 2.4mm, and a width of about 16.6mm for the 50Pin specification, making it suitable for internal connections in space-limited devices such as laptops, tablets, VR/AR, etc. For engineers, this ultra-fine structure not only saves wiring space but also puts higher requirements on conductor size, insulation layer, shielding structure, and processing consistency.
The conductor of extremely fine coaxial lines, although with a small size, its structure will directly affect resistance, current carrying capacity, signal loss, impedance stability, and high-speed signal transmission performance. Generally speaking, the smaller the cross-sectional area of the conductor, the easier it is to increase the resistance per unit length. Therefore, in extremely fine wire bundles, it is necessary to comprehensively balance the wire diameter, transmission distance, and signal requirements. At the same time, the coaxial cable is not only determined by the central conductor in terms of electrical performance; the geometric relationship between the central conductor, the insulating medium, and the outer shielding layer also affects the transmission characteristics. Taking 82907-100B-02-D as an example, its PDF corresponds to the standard wire material as AWG#46, 50Ω Micro-Coaxial Cable. Therefore, when developing alternatives, one cannot only look at "what AWG is", but also need to pay attention to the consistency of impedance, wire material structure, and terminal processing.
For engineers, the design core of ultra-fine coaxial cable assemblies is not simply to pursue being finer, but to maintain stable electrical performance and mechanical reliability within limited space. CABLINE®-UX II uses a 0.25mm pitch and offers 30, 34, 40, and 50 Pin specifications. The official reference transmission speed is 5Gbps/lane NRZ, and it also lists reference applications such as USB 3.1 Gen1, V-By-One HS 1.4, HDMI 1.3, eDP, and MIPI. Its multi-point grounding path is connected from Wire Shield, Ground Bar, Plug Shell, to Receptacle Shell all the way to PCB, which helps maintain the shielding continuity. For the development of the alternative to 82907-100B-02-D, it should focus on verifying conductor specifications, impedance, wire diameter, shielding structure, and connector end processing quality to avoid signal performance deviation caused by changes in conductor structure.
When selecting a compatible replacement harness for the 82907-100B-02-D, purchasing personnel and R&D engineers should confirm the complete "connector+cable+structure+electrical performance" rather than simply looking for products with similar appearance based on material numbers. This model corresponds to the 50Pin CABLINE®-UX II structure, with the cable end connector model being 20532-050T-02-1. The cable end connector proposed for this project is compatible with AWG#40 wire, so in the actual compatibility development, it should further confirm the outer diameter, impedance, shielding structure, and connector end crimp/assembly compatibility of the AWG#40 wire, and verify through projects such as conductivity, insulation, voltage resistance, and high-speed signals. Our company can provide: 82907-100B-02-D compatible replacement harness solutions, which can be customized and manufactured into extremely fine coaxial cables based on customer equipment space, cable length, Pin count, wire sequence, AWG specifications, and electrical performance requirements.
