I-PEX 81423-100B-02-D 30P high-speed signal transmission ultra-thin coaxial cable bundle alternative

A high-performance ultra-thin coaxial cable bundle alternative for internal connections of high-speed equipment

With the continuous development of laptops, AI terminal devices, industrial vision systems, robots, smart devices, and high-speed display devices towards thinness and high speed, there is a higher requirement for signal transmission cables inside the devices. Traditional FPC cables are gradually facing challenges in signal loss, impedance control, and anti-interference capability in terms of high-speed transmission, large bandwidth signal integrity, and complex electromagnetic environments. The extremely thin coaxial cable, with its excellent high-speed transmission performance, stable impedance control ability, and good EMI shielding performance, has become an important solution for high-speed internal connections in high-end electronic devices.

Our company specializes in the research and development as well as production and manufacturing of extremely fine coaxial cable harnesses (Micro-Coaxial Cable Harness). We can provide high-reliability and high-consistency cable harness component solutions according to customers' product requirements, and achieve compatibility and substitution for international brand connector cable harness solutions. For the I-PEX CABLINE®-CA series extremely fine coaxial cable harness products, our company can provide the I-PEX 81423-100B-02-D compatible and substitute cable harness solution to meet the requirements of 30Pin high-speed signal connection applications.

The specifications of this ultra-fine coaxial cable assembly are:

• Product Model: I-PEX 81423-100B-02-D Compatible Alternative Solution

  Connector Model: 20634-130T-02

Cable Length: 200mm

• Wire Specification: Micro-Coaxial ultra-fine coaxial cable, AWG40

The scheme adopts high-precision manufacturing technology, which can be applied to high-speed display modules, camera modules, industrial vision equipment, and internal connections of high-performance electronic devices, providing customers with a stable and reliable domestic alternative choice.

Part Two: Advantages of AWG40 ultra-fine coaxial cable束 structure and knowledge analysis of the copper material for the core

The extremely thin coaxial cable bundle usually consists of a central conductor, an insulating layer, a shielding layer, and an outer sheath. The central conductor, as the core of signal transmission, has a significant impact on the cable bundle's conductivity, flexibility, high-frequency transmission performance, and long-term reliability.

In the manufacturing process of extremely thin coaxial cable bundles, the commonly used copper materials for the core conductor mainly include the following types:

High purity oxygen-free copper (OFC / Oxygen Free Copper)

Aerated copper is one of the commonly used conductor materials in extremely fine coaxial cable bundles, with high purity and excellent conductivity. Due to its low oxygen content, the material has fewer internal impurities, which can effectively reduce signal transmission loss and improve the stability of high-speed signal transmission, making it suitable for Micro-Coaxial Cable applications with high requirements for signal integrity.

Tin Plated Copper

Tin-plated copper involves adding a tin layer on the surface of copper conductors for protection, which can enhance the conductor's anti-oxidation ability, improve welding reliability, and increase its long-term environmental adaptability. It has good application value in some cable products that require improved corrosion resistance and processing stability.

Silver Plated Copper

Silver-plated copper has superior electrical conductivity and high-frequency transmission performance, which can reduce high-frequency signal loss, and is therefore commonly used in high-speed and high-frequency communication fields. However, due to its higher cost, it is usually applied in special scenarios with higher performance requirements.

Copper Alloy Conductor

Copper alloy materials have higher mechanical strength and fatigue resistance compared to pure copper. In applications where frequent bending, dynamic movement, or space-limited equipment internal connections are required, they can improve the lifespan and reliability of wire harnesses.

The AWG40 ultra-fine coaxial cable material adopted in this scheme features a small outer diameter while balancing high-speed signal transmission capability and flexible wiring requirements. With the配合 shielding structure design, it can effectively reduce electromagnetic interference and improve the quality of high-speed differential signal transmission.

Three, I-PEX 81423-100B-02-D compatible alternative solutions to meet engineering selection and supply chain optimization requirements

For engineering and research and development personnel, when selecting high-speed ultra-fine coaxial cables, they need to pay close attention to factors such as connector matching, pin quantity, cable diameter specification, length dimension, signal integrity, and mass production consistency.

Our company provides corresponding compatible alternative products for the I-PEX CABLINE®-CA 30Pin ultra-thin coaxial cable assembly solution, which can match:

30Pin high-speed connection requirement

Selection, compatibility, and alternative solutions reference and suggestions

In the product development stage, if the customer's original design uses the I-PEX CABLINE®-CA series 30Pin ultra-thin coaxial cable assembly, it is recommended to refer to:

  I-PEX 81423-100B-02-D

Corresponding replacement direction:

  Compatible Alternative: 30Pin / AWG40 / 200mm Micro-Coaxial Harness

Selection Suggestions:

For applications such as notebook display, high-speed camera, industrial camera, and AI vision equipment, it is recommended to prioritize confirming the following parameters:

Confirm that the connector pin count matches the PCB terminal socket to avoid replacement failure due to different pin definitions.

Confirm the harness length and routing requirements. A 200mm length is suitable for most internal module connections of devices, but actual assembly verification is required for different product structures.

  Confirm high-speed signal requirements, such as USB4, DisplayPort, eDP, MIPI, and other high-speed interfaces, it is necessary to pay special attention to impedance control, crosstalk, and signal attenuation performance.

Confirm the consistency of mass production, including key manufacturing capabilities such as terminal crimping, wire processing accuracy, and connector assembly reliability.
