I-PEX 82671-100B-01-D CABLINE®-CA II 40AWG/50Ω series ultra-thin coaxial cable replacement

Product Overview: 40Pin double-ended ultra-thin coaxial cable assembly, balancing high speed and miniaturization

As laptops, tablets, VR/AR devices, and high-speed display terminals continue to develop towards slimming down and high performance, there is an increasing demand for high-speed cable harnesses within the devices. The I-PEX 82671-100B-01-D belongs to the CABLINE®-CA II series of 40Pin ultra-thin coaxial cable harnesses, using a 1-1 double-ended connection method, with a product reference length of 100mm, suitable for high-density internal high-speed signal transmission. The cable harness is matched with a cable end connector model of 20680-040T-01, corresponding to a 40Pin Plug Housing structure, with wire positioning defined as 1-1, meaning both ends of the cable harness are terminated with connectors, which can be used for signal interconnection between two high-speed connection ends within the device. For engineers, this 40Pin, high-density, double-ended termination structure is conducive to achieving multi-channel signal wiring within a limited space; for purchasing personnel, clearly defining the product part number, connector model, and wire positioning is beneficial for BOM verification, sample replacement, and bulk purchasing.

High-speed transmission capability: How is the compatibility of extremely thin coaxial cables with high-speed protocols such as USB4?

The extremely thin coaxial cable itself is not a specific high-speed communication protocol, but rather a physical cable structure used for transmitting high-speed electrical signals. Therefore, to determine whether it can be used for high-speed protocols such as USB4, Thunderbolt, and DisplayPort, it cannot be solely based on the name "extremely thin coaxial cable." Instead, it requires a comprehensive consideration of the cable structure, characteristic impedance, attenuation, crosstalk, shielding performance, connectors, and the overall signal integrity of the entire link. The CABLINE®-CA II connector is designed for high-speed signal applications, with official data indicating that it can support up to 32Gbps/lane PAM4, and is aimed at high-speed interface applications such as USB4 Gen3/Gen4, Thunderbolt 5, DisplayPort UHBR20, HDMI 2.1, eDP, etc. Therefore, I-PEX 82671-100B-01-D such 40Pin extremely thin coaxial cable bundle has the application foundation to be part of the physical transmission link for high-speed protocols like USB4. However, during engineering design, it is still necessary to perform a complete SI validation based on the specific USB4 version, actual transmission speed, cable length, impedance requirements, PCB routing, and connector combination. It cannot be simply understood as "using an extremely thin coaxial cable equals automatic support for USB4."

Engineer's focus: How to stably transmit multi-lane high-speed signals over a single cable bundle?

For the 40Pin 82671-100B-01-D, its value lies not only in "the wire being very thin" but also in its ability to achieve parallel transmission of multi-route signals through a multi-core ultra-fine coaxial structure. Each signal route has a relatively independent coaxial shielding structure, which can reduce crosstalk between adjacent high-speed channels and help control electromagnetic interference of high-speed signals during transmission. The配套's 20680-040T-01 is a 40Pin Plug Housing, combined with CABLINE®-CA II's 0.4mm Pitch high-density connector platform, can arrange more high-speed signal channels within limited PCB and structural space. For engineers involved in high-speed link design, attention should be paid to signal speed, channel length, differential pair configuration, impedance continuity, connector transition area, and shielding grounding methods; for procurement personnel, it is recommended to simultaneously confirm the number of pins, wire definition, wire length, wire material AWG, connector type, and termination method when inquiring for quotations, to avoid inconsistency in specifications caused by replacing based solely on "40Pin ultra-fine coaxial cable assembly."

Selection, compatibility, and alternative solutions reference and suggestions

If the project is using or evaluating the CABLINE®-CA II series solutions, it is necessary to find a compatible alternative cable assembly for I-PEX 82671-100B-01-D. It is recommended to first confirm the original design's 40Pin specification, 1-1 line position definition, 100mm length, and cable end connector 20680-040T-01, and then match the cable material, termination process, and electrical performance based on the actual device's high-speed signal requirements. Especially in applications such as USB4, Thunderbolt, and high-speed eDP, the alternative cable assembly cannot simply achieve "the connector can be plugged in," but should also pay attention to high-speed signal integrity, characteristic impedance, insertion loss, return loss, crosstalk, and EMI and other indicators. Our company can provide: I-PEX 82671-100B-01-D compatible alternative cable assembly solutions, which can produce and manufacture extremely thin coaxial cable assemblies according to the customer's equipment structure, cable length, Pin number, line position definition, and high-speed transmission requirements. We provide compatibility design and sample verification support for engineers, and also provide domesticated, mass-produced alternative supply options for procurement personnel.
