I-PEX 82145-100B-02-D 50P high-speed signal transmission ultra-thin coaxial cable replacement

50Pin ultra-fine coaxial cable assembly, for high-speed, miniaturized internal connections of equipment

With the continuous development of electronic devices such as laptops, AI servers, industrial cameras, machine vision, AR/VR, high-resolution displays, and robots towards high-speed, thin, and high-density, the internal high-speed signal connections of these devices have raised higher requirements for the space occupation of cables, signal integrity, anti-interference ability, and connection reliability. Traditional wiring and ordinary cables often require more optimization in terms of spatial layout, impedance control, and crosstalk suppression when faced with high-density, high-speed transmission scenarios. ultra-fine coaxial cables, with their features such as single-channel independent shielding, small size, flexible wiring, and suitability for high-speed signal transmission, are gradually becoming an important solution for internal connections in high-speed electronic devices.

This solution is for the I-PEX CABLINE®-CA series 50Pin ultra-fine coaxial cable assembly, with product part number/model 82145-100B-02-D. According to the corresponding engineering drawings, this cable assembly uses 50 AWG40, 50Ω Micro-Coaxial ultra-fine coaxial cables, with a standard length of 200±5mm. Both ends are connected using the CABLINE®-CA series connector structure, and the reverse Pin Assignment method is used for the connection, that is, Pin 1 on one end corresponds to Pin 50 on the other end, and Pin 50 on one end corresponds to Pin 1 on the other end. In terms of the cable end connector, the main connector model used for this type is 20634-150T-02, and it is combined with the corresponding Shell, Pull Bar, and end Bonding structure to form a complete ultra-fine coaxial cable assembly component. For engineers, this structure can achieve multi-channel high-speed signal connections within limited device space; for purchasing personnel, it can be compatible with existing I-PEX 82145-100B-02-D product specifications for alternative, domestic supply, or customized cable assembly development.

Our company can provide compatible and alternative cable harness solutions for I-PEX 82145-100B-02-D. These solutions can be custom manufactured based on customer's existing equipment structure, connector requirements, cable length, pin count, material specifications, and wire exit direction, etc., providing a stable supply chain alternative for internal cable harnesses of high-speed electronic equipment.

What high-speed protocols are suitable for ultra-fine coaxial cables? What should engineers focus on when selecting them?

The ultra-fine coaxial cable is not only corresponding to a single communication protocol, but also a cable connection form suitable for high-speed, high-frequency signal transmission. According to the product information of the CABLINE®-CA series, its application direction covers a variety of high-speed interfaces, including USB4, Thunderbolt, DisplayPort, eDP, HDMI, V-By-One, MIPI, and USB 3.2 high-speed transmission applications. The data shows that the CABLINE®-CA series can support high-speed data transmission up to 32Gbps/Lane PAM4, and can be applied to high-speed interface scenarios such as USB4 Gen4, DisplayPort UHBR20, V-By-One US, HDMI 2.1, USB 3.2 Gen2, and eDP.

For engineers, when selecting ultra-fine coaxial cable bundles, it cannot be simply assumed that "if the cable supports high-speed protocols, it will definitely meet the requirements of the whole machine protocol." The actual high-speed transmission performance is closely related to factors such as connectors, cable impedance, cable length, Pin Assignment, PCB routing, differential pair layout, return loss, insertion loss, and crosstalk. Therefore, when carrying out high-speed cable replacement design, it is recommended to maintain the original scheme's connector system, cable diameter, impedance, Pin quantity, cable length, and termination structure as much as possible, and then perform signal integrity verification according to the actual project.

For example, with the part number 82145-100B-02-D, the corresponding cable is AWG40, 50Ω Micro-Coaxial Cable with a 50Pin structure that provides a high channel density. For devices using high-speed display, camera, and high-speed data transmission architectures, extremely thin coaxial cables can be used as an internal connection solution between the motherboard and display module, camera module, or other high-speed function modules. At the same time, the 0.4mm pitch, horizontal insertion structure, approximately 1.0±0.1mm mating height, and mechanical lock design of CABLINE®-CA make it suitable for thin, high-density electronic devices with high requirements for internal installation space.

From the perspective of wire compatibility, when customers are replacing connectors and harnesses, they also need to pay attention to the wire specifications corresponding to the connectors used. 20634-150T-02 is one of the connector models used in this scheme. According to the information provided by the current project, its compatible wire specifications are 36AWG, 8AWG, 40AWG, 42AWG, and 44AWG. It should be particularly noted that the corresponding specification records in the currently uploaded CABLINE®-CA product materials are 36AWG, 38AWG, 40AWG, 42AWG, and 44AWG. Therefore, if "8AWG" is not a special specification of the project, it is recommended to further confirm whether it should be 38AWG before officially releasing the website content to avoid discrepancies in specification understanding by engineering and procurement personnel.

Section 3: Selection, Compatibility, and Alternative Solutions Reference and Recommendations

For equipment manufacturers, R&D engineers, and purchasers using the I-PEX CABLINE®-CA solution, if the goal is to find a compatible replacement cable assembly for the 82145-100B-02-D, it is recommended to first confirm several key parameters of the original product: 50Pin quantity, Micro-Coaxial ultra-fine coaxial structure, AWG wire gauge, 50Ω impedance, 200±5mm cable length, connector structure at both ends, and 1-N reverse Pin Assignment. These parameters directly relate to whether the new cable assembly can achieve mechanical assembly and electrical connection on the original equipment, especially the Pin Assignment. If the cable sequence is different from the original product, even if the connector shape can be properly inserted, it may cause misalignment of the signal channel, so it should be a key item to confirm during the development of the replacement cable assembly.

In terms of connectors, this solution involves the CABLINE®-CA 50Pin Plug/Harness structure, with the connector body model being 20634-150T-02. The corresponding accessories include components such as Shell and Pull Bar. For procurement alternatives, three approaches can be considered: "same series compatibility, same specification substitution, and custom according to the original design." If the client wishes to minimize design changes, priority can be given to 1:1 compatibility development based on the original I-PEX product's connector, pin count, wire diameter, impedance, and length; if the client wishes to implement domestication or introduce a second supplier, then the connector and harness termination structure can be reconfirmed based on actual assembly space while maintaining the device interface size and electrical requirements unchanged; if the existing standard products cannot fully meet the equipment requirements, further customization can be carried out on aspects such as length, pin assignment, cable exit direction, tape position, and binding method.

For the purchasing department, it is not only necessary to compare the unit price, but also to focus on confirming whether the harness can be produced in bulk stably, as well as whether the supplier has the ability to terminate, strip, weld, insulate, shield, and inspect the extremely thin coaxial lines. For R&D engineers, it is recommended to simultaneously verify key indicators such as insertion reliability, wire sequence, conduction, insulation resistance, voltage resistance, and high-speed signal integrity at the stage of sample introduction. This can both reduce the risk of alternative material introduction and is beneficial for the subsequent shift from a single-brand supply system to a multi-supplier supply system.
