Very thin coaxial (micro-coaxial) harness assemblies are widely used in the design of high-speed communications and compact electronics because of their high density, fine pitch and excellent signal integrity. To I-PEX 81423-100B-02-D this classic CABLINE®-CA series multi-pin wiring harness, for example, with 0.4mm spacing and 30-bit plug-in structure, is suitable for high-speed data and control/power transmission applications between small modules. It is a common scheme in many visual, wireless and embedded devices.

However, in the face of engineering pain points such as long delivery period and lack of flexibility in mass customization, the design and production capacity of alternatives to this precision wiring harness has become a key consideration for many product development teams. This article will be based on the technical characteristics of the model and our company's manufacturing capabilities, from the perspective of engineering selection logic to introduce the feasibility and advantages of alternatives.

1.2. Focus on engineering selection

When selecting alternatives, engineers usually consider the following core elements:

1. Electrical performance and signal integrity

The ultra-thin coaxial structure has good shielding and impedance control, which helps to suppress crosstalk and signal loss. Substitutes must reproduce or optimize these characteristics.

2. Mechanical interchangeability and connection reliability

The matching of the corresponding plug bolt, film size and mating interface is the key; especially in assembly and field maintenance, stable connection characteristics are very important.

3. Manufacturing consistency and batch stability

The repeatability of the production process and the mechanical and electrical consistency of each batch of products determine the controllability of mass production.

Engineering Logic for 2. Substitute Product Development

The technical core of the replacement I-PEX 81423-100B-02-D product is:

2.1. Use the same or equivalent miniature coaxial core material and shielding structure as the prototype to ensure signal integrity and transmission rate matching.

2.2. Maintain 0.4mm spacing and 30-bit structure configuration to make it compatible with existing PCB connectors and system structures.

2.3, the introduction of reliable mechanical buckle and stress buffer design, improve durability and assembly convenience.

These design considerations not only match the original factory specifications, but also allow engineers to reduce the amount of redesign in the replacement process.
