In the design of electronic products with high-speed data transmission and limited space, the very thin coaxial wire harness assembly (micro-coaxial cable) is one of the key components to achieve high-density wiring and reliable signal integrity. For example, I-PEX 81465-100B-02-D is a common 30-terminal rectangular plug-plug very thin coaxial wire harness assembly, which is widely used in high-speed signal connection scenarios such as display modules, camera modules, portable devices, etc.

As supply chain diversity and the need for cost optimization increase, engineers are increasingly focused on finding reliable supply alternatives to existing components with consistent performance. After in-depth study of the specifications and design features of such products, we propose a professional solution that can be manufactured and replaced with this model to support customers in painless replacement and industrial mass production.

Analysis of Basic Characteristics of 1. Products

Taking I-PEX 81465-100B-02-D as an example, the main technical features of this component include:

1.1. Type: 30-position rectangular wire harness assembly (Plug-Plug), used for board-to-board/module interface connection.

1.2. Connection characteristics: 0.4mm spacing, miniature coaxial arrangement, shielded, with mechanical lock design.

1.3. Length: about 200mm(± 5mm) wire length, suitable for internal wiring jumper.

1.4, structure: the use of very thin coaxial cable (AWG40, etc.), to achieve low crosstalk and high bandwidth transmission performance.

This type of wiring harness is often selected for high-speed differential signal paths, such as LVDS, MIPI, USB3.0/PCIe low-speed auxiliary lines and other modules.

2. engineering selection concerns

When evaluating whether a model component can be replaced, the following key engineering indicators should be paid attention:

2.1. Matching of electrical characteristics:

Impedance Matching: Keep the 50Ω coaxial structure to reduce reflection and signal loss.

Transmission rate: The overall design and shielding characteristics of the component must meet the target bandwidth (such as differential signals above 10 Gbps).

2.2, mechanical and assembly compatibility:

Number of terminals and spacing: The number of terminals (e. g. 30P) and spacing (0.4mm) of the substitute parts should match the original design.

Terminating form: The plug-to-plug mating form must be maintained to fit the existing connector.

2.3, Dimensions and Wiring Design:

The line length and bending radius should match the overall space of the product to avoid affecting the assembly process and EMC performance.

3. the benefits of our alternatives

Based on the above selection logic, we propose the manufacturing capacity of equivalent alternatives for I-PEX products, which has the following advantages:

3.1, standardized production and customized support:

We have professional equipment and technology suitable for ultra-fine wire harness processing, and can provide alternative products according to the following requirements: fully shielded micro-coaxial wire harness, various terminal numbers (such as 30P, 40P, 50P) and different wire lengths, 0.4mm/0.5mm and other spacing options; Compared with a single original part, we can provide more flexible material configuration without reducing performance.

3.2, engineering support through selection to mass production:

We not only provide materials, but also provide engineering support based on EMC and signal integrity analysis to help customers confirm the feasibility of alternative solutions in specific applications.

3.3, can be extended to the series of products to replace:

In addition to I-PEX 81465 models, we also have the manufacturing capacity to produce similar series of products such as [I-PEX CABLINE-CA HAR 50P 200MM] [I-PEX CABLINE-UX II HAR 40P 300MM] [I-PEX CABLINE-UA II HAR 50P 200MM], which can cover a wider range of terminal numbers and wiring requirements.
