I-PEX 81462-100B-02-D 40P high-speed signal transmission ultra-thin coaxial cable replacement

One, 40PIN high-density design, ultra-fine coaxial cable assembly for internal connections of high-speed equipment

With the continuous development of laptops, tablets, high-speed display devices, and other miniaturized electronic equipment towards thinness and high speed, the internal connections of these devices have higher requirements for the space occupied by cables, signal transmission capability, and connection reliability. In response to such applications, our company can provide ultra-fine coaxial cable manufacturing and alternative solutions that match the specifications of the I-PEX CABLINE®-CA II series. The product model highlighted in this introduction is I-PEX 81462-100B-02-D, which belongs to the ultra-fine coaxial cable specification of 40PIN, Micro-Coaxial, AWG40, length 200mm, and 1-N; I-PEX official documents also clearly list 81462 as a standard Harness model for CABLINE-CA II 40Pin, 40AWG, L=200mm. From the engineering structure perspective, this solution adopts a high-density connection method with 40PIN and 0.4mm Pitch. The Plug Housing model for the cable connector is 20680-040T-01, corresponding to the 40Pin structure. For engineers, these ultra-fine coaxial cables can achieve multi-channel signal connections in limited internal space of the device; for purchasers, the clear material number, Pin count, Pitch, cable specification, and length are conducive to material assessment, BOM verification, and supplier introduction.

Does the ultra-fine coaxial cable support USB 3.1 Gen 2 transmission? The key is not just to look at "the line is very thin."

"Is the ultra-thin coaxial cable compatible with USB 3.1 Gen 2 transmission?" is a frequently asked question in engineering applications. The answer cannot be simply understood as "all ultra-thin coaxial cables support it," but should be judged in combination with the cable structure, characteristic impedance, transmission length, connector, Pin Assignment, and the overall signal integrity of the high-speed channel. According to USB-IF data, USB 3.1 Gen 2 corresponds to a transmission capability of 10Gbps; while the current USB 3.x specification system has incorporated the previous related specifications into USB 3.2, USB 3.2 Gen 2 also corresponds to a 10Gbps level of transmission. The official product information of I-PEX's CABLINE-CA II currently lists **USB 3.2 Gen 2 (10Gbps/lane)** as a suitable standard reference, and its connector platform is also aimed at higher-speed applications such as USB4. Therefore, from the perspective of the connector platform and high-speed application positioning, CABLINE-CA II has the technical foundation for 10Gbps-level signal applications such as USB 3.1 Gen 2/USB 3.2 Gen 2; however, for the specific 81462-100B-02-D, it cannot be claimed that it has passed a complete certification of a certain USB standard solely based on "40PIN, AWG40". Actual projects still need to be confirmed based on the specific impedance control of the cable material, cable length, shielding structure, connector combination, and high-speed test results at the system end. For engineers, what truly needs to be focused on is the impedance continuity and signal integrity of the entire high-speed link, rather than simply judging whether "the ultra-thin coaxial cable can run USB 3.1 Gen 2."

Three, selection, compatibility, and alternative solution references and suggestions: confirm from material number and structure to high-speed performance

In actual selection and domestic substitution projects, it is recommended that engineers and procurement personnel not solely rely on the "40Pin connector" as a basis for judgment, but should confirm each item around material number, connector structure, wire specification, length, Pin Assignment, and electrical performance. For I-PEX 81462-100B-02-D, its core specifications can be understood as a 40Pin ultra-fine coaxial cable束 + AWG40 Micro-Coaxial Cable + 200mm length + 1-N connection scheme; I-PEX official documentation also lists different length models such as 40Pin, 100mm, and 300mm in the same series. Therefore, in actual projects, if the equipment structure changes, selection can also be re-done based on length and connection method. For substitution projects, it is especially necessary to confirm the key structural parameters related to the wire end connector such as 20680-040T-01, 40PIN, 0.4mm Pitch, and further verify the actual mating end, cable exit direction, and installation space. It should be particularly emphasized that substitution is not just about achieving "plug and play," but should maintain the original scheme's mechanical matching, electrical performance, and high-speed signal transmission characteristics as much as possible. Our company can provide: 81462-100B-02-D compatible substitution cable solution, which can be matched for manufacturing according to the customer's actual product structure and technical requirements, including ultra-fine coaxial wire material, connector assembly, cable length, and processing technology. We can provide the corresponding ultra-fine coaxial cable solution for engineering verification, sample making, and bulk purchasing.

Four, AWG40 ultra-fine coaxial cable manufacturing capability, taking into account engineering verification and procurement import requirements

For a 40PIN high-density ultra-fine coaxial cable assembly, the AWG specification is an important parameter for engineers in signal, electrical, and space design, and it is also a key product information that procurement personnel need to confirm when evaluating supplier alternatives. The 81462-100B-02-D uses AWG40 Micro-Coaxial Cable, and the official documentation of the I-PEX CABLINE-CA II series explicitly lists the support specifications for AWG40 ultra-fine coaxial cables, along with the current capacity corresponding to different wire diameters; for AWG40, the official documentation provides a rated current reference value of 0.3A/contact, with a maximum support of 50 contacts. Based on this, our company provides professional manufacturing and alternative accessories for ultra-fine coaxial cable products, and can confirm specifications based on the specific BOM, original cable material number, and internal installation requirements of the equipment. For engineers and procurement personnel looking for alternative suppliers for the I-PEX 81462-100B-02-D, a comprehensive assessment can be made from dimensions such as sample matching, structural confirmation, wire specifications, impedance control, processing consistency, and bulk supply capacity. Our company can provide a compatible alternative cable solution for the 81462-100B-02-D, helping customers reduce the difficulty of supply chain introduction and providing reliable ultra-fine coaxial cable manufacturing support for high-speed, miniaturized electronic devices.

I-PEX 81462-100B-02-D is a typical 40PIN high-density ultra-fine coaxial cable assembly solution, with core specifications including 40PIN, 0.4mm connector spacing, AWG40 Micro-Coaxial Cable, and 200mm cable length. For high-speed applications such as USB 3.1 Gen 2 with 10Gbps, whether it can meet actual transmission requirements needs to be comprehensively verified by combining specific wire materials, impedance, connectors, length, and overall signal integrity, and cannot be made an absolute judgment solely based on the wire material category. For enterprises that are in the process of original factory replacement, domestic introduction, or supplier development, our company can provide I-PEX 81462-100B-02-D compatible alternative ultra-fine coaxial cable assembly solutions. Guided by engineering matching and actual application needs, we can provide customers with professional ultra-fine coaxial cable assembly product support from sample verification to mass production.
