I-PEX 82975-100B-01-D 10P high-speed signal transmission ultra-thin coaxial cable replacement

A 10Pin ultra-fine coaxial cable bundle for high-speed display and image transmission

In notebook computers, industrial cameras, machine vision, high-resolution displays, AI vision equipment, and other high-density electronic devices, 4K image transmission imposes higher requirements on the signal integrity, spatial dimensions, and connection reliability of internal high-speed cable harnesses. The I-PEX CABLINE®-CA series is a type of ultra-thin coaxial connector solution with a 0.4mm pitch and horizontal mating, which is officially positioned for the highest 32 Gbps/Lane level of high-speed applications, and supports Micro-Coaxial Cable, mechanical lock, shielding, and multi-point grounding designs. The targeted product in this article is I-PEX 82975-100B-01-D, with specifications corresponding to 10Pin, Micro-Coaxial 40AWG, cable length 200mm, and 1-1 wire position definition; the matching connector model at the cable end is 20634-210T-02. According to the product information we have, our company can provide a compatible alternative manufacturing solution for ultra-thin coaxial cable harnesses for this specification. We offer customers an integrated cable harness solution from wire materials, termination, assembly, to finished product inspection, catering to engineering development, sample verification, mass production introduction, and supply chain substitution needs.

Specification Analysis of 82975-100B-01-D: What should engineers and purchasers focus on when selecting?

For engineers, selecting such ultra-fine coaxial cable assemblies cannot simply be based on checking "10Pin" and "200mm", but also requires confirming the connector series, wire material AWG, wire position definition, impedance system, termination structure, and high-speed signal performance. The I-PEX 82975-100B-01-D corresponds to CABLINE-CA 10Pin, 40AWG Micro-Coaxial, 200mm, 1-1 Harness, and the I-PEX official product page explicitly lists the 82975 model; the CABLINE-CA series uses 0.4mm contact spacing, horizontal insertion, 1.0±0.1mm insertion height, connector depth of 5.73mm, and supports 10～60Pin specifications. For this solution, the wire material connector model is 20634-210T-02, and the cable harness wire position definition is 1--1. Therefore, when making alternative designs, the "10Pin / 40AWG / 200mm / 1--1 / corresponding connector" should be confirmed as a basic specification combination, and not solely based on appearance similarity or Pin number equivalence. For purchasers, this parameterized definition is also more conducive to supplier pricing comparison, sample recognition, alternative material introduction, and bulk procurement. It is particularly important to clearly specify wire length tolerance, termination direction, Pin Mapping, wire material structure, and high-speed performance requirements in the procurement specification document to avoid situations where "the connector can be inserted, but the overall high-speed link performance is not equivalent."

What specifications are required for a very thin coaxial cable for 4K image transmission?

"4K image transmission" does not correspond to a single fixed material specification. The actual requirements depend on the frame rate, bit depth, chroma sampling method, and the transmission protocol used under 4K resolution, such as HDMI, DisplayPort/eDP, USB4, etc. Therefore, during engineering design, it is more important to pay attention to the Signal Integrity of the entire high-speed channel rather than just looking at whether the cable is labeled as "supporting 4K." For extremely thin coaxial cables, the focus should be on characteristic impedance and consistency, Insertion Loss (insertion loss), Return Loss (return loss), Crosstalk (crosstalk), differential pair delay/skew, shielding and grounding continuity, impedance changes in the connector transition area, and the impact of cable length and bending on high-speed signals; the CABLINE-CA official high-speed test data uses AWG40, 45Ω Micro-Coaxial Cable, 100mm as test conditions, and takes 32 Gbps/Lane as the reference high-speed transmission capability. Therefore, if customers need to use such cables for 4K60, 4K high refresh rate, or higher bandwidth image transmission, it is recommended to combine actual protocols for TDR, S parameters, Insertion Loss, Return Loss, Crosstalk, and the overall BER/eye diagram during the project import phase, and use the final system's TX/RX capabilities and interface specifications as the basis for judgment; "40AWG" itself is not a sufficient condition for 4K transmission. What truly determines the reliability of the high-speed link is the complete transmission channel formed by the cable, connector, termination technology, and PCB. The CABLINE-CA official lists reference high-speed applications including USB4 Gen 4, USB4 Gen 3, DisplayPort UHBR20, HDMI 2.1, USB 3.2 Gen2, eDP, etc., which can serve as a reference for high-speed internal connection scheme selection.

Four, selection and compatibility and alternative solutions reference and suggestions

If the customer's current design uses I-PEX 82975-100B-01-D and wishes to seek a domesticated, second supplier, or cost-optimized solution, it is recommended to first establish an alternative specification benchmark with the original model's 10Pin, 200mm, 40AWG Micro-Coaxial, 1-1 line position definition, connector model 20634-210T-02, and actual assembly direction. Then, confirm the wire diameter, impedance, shielding structure, termination size, and electrical performance based on the internal space and high-speed protocol requirements of the customer's equipment. The I-PEX official CABLINE-CA series also provides similar models such as 82974-100B-01-D (100mm, 1-1) and 82976-100B-01-D (300mm, 1-1), so if the customer's actual application length varies, specification matching can also be done according to the same Pin number, wire material, and connection structure; however, it should be noted that different lengths will change the high-speed channel loss and overall SI performance, and it cannot be directly judged as completely equivalent in performance based solely on "same series, same Pin number". Our company can provide: I-PEX 82975-100B-01-D compatible alternative cable harness solutions, which can be customized and produced according to customer samples, drawings, or technical specifications, and can carry out targeted verification around wire material selection, termination accuracy, line position definition, length control, connector matching, and high-speed transmission performance; for projects that require second suppliers, domestic alternatives, cost optimization, or stable supply, further sample prototyping, specification confirmation, and reliability testing can be carried out. It should be particularly emphasized that "compatible alternatives" should be determined based on the actual connector mating, mechanical dimensions, electrical performance, and high-speed link verification results of the customer, and it is recommended to complete sample testing and specification freezing recognized by both parties before mass production.

I-PEX 82975-100B-01-D is a 10Pin, 200mm, 40AWG, 1-1 fine coaxial cable assembly product with clear engineering specification definition, with the matching cable end connector model being 20634-210T-02. For 4K and higher speed image transmission applications, what is truly worth paying attention to is the complete high-speed link performance formed from the cable, connector, termination process to the PCB interface, not just the product's pin count, length, or AWG specification. With the ability to produce extremely fine coaxial cable assemblies, our company can carry out compatible alternatives, second supplier introduction, domestic substitution, and customized cable development around this model, helping engineers reduce the difficulty of high-speed internal connection design and verification, and also providing more flexible and stable supply chain options for purchasers.
