I-PEX 83038-100B-01-D 40P high-speed signal transmission ultra-fine coaxial cable replacement

What is the product of I-PEX 83038-100B-01-D? What core specifications should the engineer first confirm?

For laptops, display modules, camera modules, VR/AR devices, and other space-limited electronic devices, ultra-fine coaxial cable bundles are responsible for high-speed signal transmission while also needing to complete high-density wiring within limited space. Therefore, engineers cannot simply look at "40Pin" or "200mm length" when selecting cable bundles, but need to confirm the connector series, Pin count, wire material AWG, impedance, cable length, wiring structure, and connection methods at both ends. The corresponding product part number/model for this time is I-PEX 83038-100B-01-D, which belongs to the CABLINE®-UA II 40Pin ultra-fine coaxial cable bundle. The drawing corresponds to a product length of 200 mm, using 40 AWG #44, 50Ω Micro-Coaxial Cable (ultra-fine coaxial cable) internally, and both ends are structured with corresponding 40Pin connectors. According to I-PEX official data, CABLINE-UA II uses a 0.3 mm Contact Pitch, Vertical (Right Angle) connection direction, supports 26/32/40/50 Pin, and supports AWG42, AWG44, AWG46 Micro-Coaxial Cable; the recommended part number for the 40Pin Plug Housing is 20497-040T-30. For purchasers, it is recommended to use the complete model I-PEX 83038-100B-01-D as the basic identification information when inquiring, rather than just describing "40Pin ultra-fine coaxial cable" or "CABLINE-UA II cable bundle," as the same series may have products with different Pin counts, different lengths, and different termination structures. An incomplete model number can easily lead to discrepancies in procurement specifications.

How to confirm the model of a very fine coaxial cable connector? Don't just look at the appearance of the connector.

In the actual engineering replacement and procurement process, "how to confirm the connector model" is a very critical step. For micro connector systems like CABLINE-UA II with a 0.3 mm pitch, engineers are best to confirm from four levels: connector series + Pin number + connector category + complete Part Number. First, confirm whether the series is CABLINE-UA II; second, confirm the Pin quantity, this product belongs to the 40Pin version; then further confirm the connector component used at the wire end. For this I-PEX 83038-100B-01-D ultra-thin coaxial cable assembly, the connector model used at the wire end is 20497-040T-30, corresponding to the CABLINE-UA II 40Pin Plug Housing; the I-PEX official material number list clearly lists different versions such as 26P, 32P, 40P, and 50P, for example, the 40Pin Plug Housing is 20497-040T-30, and the 40Pin Receptacle is 20498-040E-41. Therefore, when purchasing connectors or looking for alternative cable assemblies, it is necessary to distinguish between "wire end Plug Housing" and "PCB end Receptacle" and not rely solely on the "20497/20498 series" for judgment. At the same time, it is also necessary to check the wire specifications and structure: this product uses AWG #44 Micro-Coaxial Cable, and although the official information of CABLINE-UA II supports AWG42, AWG44, AWG46, and other wire diameters, the electrical and mechanical conditions corresponding to different AWG are not completely the same. Therefore, if the original equipment of the customer uses AWG44, it is not recommended to simply replace it with AWG42 or AWG46. For procurement, the most secure confirmation method is to have the supplier check each item according to the original material number, engineering drawings, connector model, Pin number, wire AWG, and length, thus avoiding the problem of "the connector series is the same, but the Pin number or wire specification is inconsistent."

Three, selection and compatibility and alternative solutions reference and suggestions: with complete specification matching as the core

If the customer is looking for a replacement for the extremely thin coaxial cable assembly I-PEX 83038-100B-01-D, it is recommended not to simply perform a "model replacement" but to confirm by matching engineering specifications item by item. The key matching conditions for this product include the CABLINE-UA II series, 40Pin, 0.3 mm Pitch, AWG #44 Micro-Coaxial Cable, 50Ω, 200 mm cable assembly length, and the corresponding cable end connector 20497-040T-30. In addition, the actual equipment structure should be confirmed for the cable exit direction, cable assembly arrangement, fixing method, and termination structure. Similarly, in the official I-PEX sample model, it can be seen that there are different lengths such as 100 mm, 200 mm, and 300 mm for 40Pin, 44AWG Micro-Coaxial Cable, such as the official listed 40Pin, 44AWG, 200 mm, 1-1 structure sample model, which is 83038-100B-01-D. Therefore, the length and termination structure in the model are also important for confirming the replacement. For customers in need of domestication, supply chain optimization, second supplier introduction, or replacement of existing cable assemblies, our company can match specifications and develop compatible solutions based on the original material number, samples, engineering drawings, or physical items provided by the customer. We can match around connectors, AWG cables, impedance, pin positions, length, and finished product structure. Our company can provide: I-PEX 83038-100B-01-D compatible replacement cable assembly solutions, which can carry out corresponding extremely thin coaxial cable assembly manufacturing and replacement solution evaluation for the 40P, AWG #44 extremely thin coaxial cable, 200 mm length, and 20497-040T-30 cable end connector. For engineers, if it is a new project introduction, it is recommended to confirm whether the connector matches the existing PCB terminal socket first, then confirm the cable specifications and signal requirements; for purchasers, it is recommended to directly state the complete material number, pin count, AWG, length, and connector model in the inquiry form, so that suppliers can accurately quote and reduce the time for repeated sample confirmation.

Four, reliable alternative for engineering applications: from "connectable" to "specification matching"

The replacement of extremely fine coaxial cable assemblies is not as simple as connecting wire at both ends of the connector, but requires considering size, termination, signal, and assembly requirements simultaneously. CABLINE-UA II itself adopts a miniaturized 0.3 mm Pitch structure, and the official documentation provides a reference transmission speed of 5 Gbps/lane NRZ, listing reference applications such as USB 3.1 Gen 1, V-By-One HS 1.4, HDMI 1.3, eDP, and MIPI; the actual system performance still needs to be evaluated in combination with wire, length, PCB, and overall signal integrity design. Therefore, when replacing I-PEX 83038-100B-01-D, engineers truly need to pay attention to "whether the connector model is correct, whether the 40Pin corresponds, whether the AWG #44 wire is matched, whether the 50Ω characteristic impedance meets the system requirements, whether the 200 mm length fits the device wiring space, and whether the finished termination structure can be assembled normally", while procurement needs to focus on supply stability, sample verification, batch consistency, and the cost and delivery time after replacement. Through complete specification confirmation, the risk of judging compatibility solely based on appearance or a single size can be avoided.

I-PEX 83038-100B-01-D is a CABLINE-UA II ultra-thin coaxial cable assembly with a 40Pin, AWG #44, 50Ω micro-coaxial cable, 200 mm in length; its cable end connector model is 20497-040T-30. **For customers looking for domestic alternatives, second suppliers, or custom cable assemblies of the same specification, our company can provide I-PEX 83038-100B-01-D compatible alternative cable assembly solutions, confirm specifications and product manufacturing according to the actual equipment and engineering requirements of customers, and provide a more direct solution for engineers to select and purchase alternatives.**
