I-PEX 82447-100B-02-D CABLINE®-UX II 40AWG/50Ω series ultra-thin coaxial cable bundle alternative

During the selection process of extremely thin coaxial cable assemblies, engineers often pay attention to "How much current can a line as thin as AWG46 actually handle?" In fact, the current carrying capacity of extremely thin coaxial cables needs to be judged comprehensively based on the cable specifications, connector terminal rated current, number of contacts, temperature rise, and actual working environment. Taking I-PEX 82447-100B-02-D as an example, this product belongs to the CABLINE®-UX II 50Pin extremely thin coaxial cable assembly, using AWG #46, 50Ω Micro-Coaxial Cable, 300mm in length, and 1-N wire position definition. The connector model used at the cable end is 20532-050T-02-1. The official I-PEX specifications for CABLINE®-UX II give the current ratings: AWG46 Micro-Coax 0.1A/contact, AWG44 Micro-Coax 0.15A/contact; AWG39 Discrete Wire as 0.5A/contact, but up to 6 contacts. Therefore, for the 82447-100B-02-D, the actual AWG46 scheme adopted should be given priority, which is the 0.1A/contact series of connector rated parameters.

For procurement and engineering design, this is a very easy place to misunderstand. 0.1A/contact is the rated current reference value for the contact point, and it does not mean that the entire 50Pin cable harness 82447-100B-02-D can be directly defined as having a 5A continuous working capacity. The actual current carrying capacity is also affected by factors such as conductor cross-sectional area, insulation material, internal heat dissipation conditions of the cable harness, the number of adjacent conductive cores, contact resistance, environmental temperature, and allowable temperature rise. Especially for 82447-100B-02-D, which uses extremely thin AWG #46 coaxial cable, the design focus is on high density, high flexibility, and high-speed signal transmission, rather than as a large current power line. I-PEX data also shows that CABLINE®-UX II uses a 0.25mm contact pitch, supports 30, 34, 40, and 50Pin, and has a very compact structure, making it more suitable for high-speed connections for display, data, and small devices in actual applications.

From the product structure perspective, 82447-100B-02-D uses a 50-core AWG #46, 50Ω Micro-Coaxial Cable, with both ends mating with the CABLINE®-UX II structure. The wire position is defined as 1-N, corresponding to a 300mm standard harness. The I-PEX CABLINE®-UX II employs a 0.25mm ultra-narrow Contact Pitch and a Vertical (Right Angle) structure, with a height of approximately 1.04mm, and forms a grounding path through Cable Shield → Ground Bar → Plug Shell → Receptacle Shell → PCB; the official reference transmission speed is 5Gbps/lane NRZ. Therefore, for engineers, the value of such ultra-fine coaxial harnesses is mainly reflected in high-speed signal transmission, space saving, flexible cabling, and shielding performance, rather than pursuing greater current carrying capacity.

If the customer needs to purchase or develop a compatible substitute product for the I-PEX 82447-100B-02-D, it is recommended to first confirm the key conditions such as 50Pin, AWG #46, 50Ω Micro-Coax, 300mm, 1-N wire position definition, and the wire material end 20532-050T-02-1, and then confirm which Pins carry signals and which Pins may involve power supply according to the actual application, and verify the number of live Pins and temperature rise. It is not advisable to judge the maximum current of the entire harness solely based on the parameter "0.1A/contact", and it is even more not recommended to use the extremely thin coaxial cable as a general-purpose high-current power supply cable directly. For projects that require domestic substitution, sample prototyping, or bulk purchasing, our company can provide: I-PEX 82447-100B-02-D compatible substitute cable harness solutions. We can match and develop connectors, AWG specifications, impedance, length, wire position definitions, and processing structures according to customer drawings, samples, and application requirements.

The current capacity of ultra-fine coaxial cables should be judged according to specific specifications.
On a comprehensive level, there is no unified "maximum current" value for extremely fine coaxial cables that applies to all products. For the I-PEX 82447-100B-02-D 50Pin extremely fine coaxial cable assembly, which uses AWG #46, 50Ω Micro-Coaxial Cable, the I-PEX CABLINE®-UX II series documentation specifies an AWG46 current rating of 0.1A/contact. This parameter should be understood as the rated current reference for the corresponding contacts and not simply deduced as the entire 50Pin cable assembly can carry 5A continuously. Engineers should verify this in design by considering the actual number of powered pins, operating temperature, allowable temperature rise, and application conditions.
