In high-performance electronic systems, connectors and wiring harness assemblies often assume key responsibilities for high-speed signal transmission and spatial layout. As a widely used connection solution in the industry, I-PEX CABLINE®-VS, CABLINE®-Similar types of micro-coaxial connection components such as SS have been implemented in large-scale applications in consumer electronics, communications and industrial equipment.

This article focuses on the I-PEX brand under the 82067-100B-02-D model-a typical CABLINE®-VS 20P micro coaxial harness assembly (20 contacts, 200 mm length, plug-in to plug-in structure), and around its key technical characteristics and engineering selection logic, discuss how we can develop and provide alternative products that meet equivalent electrical and mechanical properties.

1. product background and main technical characteristics

I-PEX 82067-100B-02-D is part of its CABLINE®-VS series of micro-coaxial wiring harness components, this series is an industry-proven VESA standard connection solution, widely used for high-speed data channels and compact space internal wiring requirements.

Major engineering indicators include:

1.1. Micro coaxial cable structure: AWG#40 grade micro coaxial wire is adopted, with 50 Ω characteristic impedance matching and reliable high-speed signal transmission.

1.2, 20 contact design: corresponding to the horizontal plug-in structure (plug-to-plug), suitable for space-constrained module connection.

1.3, 0.5mm contact spacing (pitch) and mechanical buckle design: to ensure connection reliability and stable electrical performance.

1.4, length and flexibility: standard 200 mm wire length to adapt to typical internal wiring layout, at the same time can be adjusted according to the actual layout.

These components are commonly used in notebook displays, camera modules, communication devices, or high-speed data line interconnections, and their selection focuses on engineering requirements such as signal integrity, EMI shielding, and dimensional constraints.

2. Engineering Selection Logic: Concerns and Evaluation Dimensions

When designing alternatives for this type of micro-coaxial harness, engineers typically weigh around the following core selection dimensions:

2.1. Signal integrity and transmission performance:

For connection tasks that support high-speed protocols (such as USB4, PCIe, MIPI, etc.), the characteristic impedance of the wire, insertion loss/return loss (Return Loss) and other indicators directly affect the final performance. Therefore, replacement products need to ensure equivalent impedance matching and cable structure design to maintain high-frequency signal integrity.

2.2. Mechanical consistency and assembly suitability:

Since the spacing between 20 contacts and 0.5mm is an industry standard, the alternative scheme needs to provide the same size, the same insertion and removal direction and mechanical lock to ensure the exchange with the existing PCB interface and equipment.

2.3. Environmental and reliability indicators:

For possible vibration, thermal cycling or electromagnetic interference environment, the harness assembly must have sufficient life and stability. Common engineering evaluations include indicators such as insulation resistance, withstand voltage, and operating temperature range.

3. our alternative product strengths and engineering practices

For the application scenarios and performance requirements of I-PEX 82067-100B-02-D, we developed an alternative with the following engineering advantages:

3.1. Customized coaxial layout: According to the customer's specific signal routing and EMI requirements, the harness length, shielding layer structure and interface layout can be adjusted to meet different installation space and signal isolation specifications.

3.2. Standard compatible 20P structure: the substitute is compatible with the original model in terms of connection number, spacing and plug-in direction, and can directly match the original design connector, which is convenient for engineering verification and system replacement.

3.3, controllable transmission performance: through strict cable and shielding design, to ensure consistent characteristic impedance, plug loss control, adapt to high bandwidth requirements of the internal high-speed signal link.

3.4. Engineering support and quality traceability: provide complete BOM configuration, test report support, and provide small batch proofing or mass production according to customer requirements to shorten the development cycle.
