In the design of modern high-density interconnection systems, ultra-fine coaxial wire harness components are increasingly becoming the core components of high-speed data and signal transmission. I-PEX 81421-100B-02-D(CABLINE®-VS series) is a typical 30-pin extremely fine coaxial connection harness assembly in the industry, which is widely used in high-speed and high-integrity connection applications between PCB modules. As the system's requirements for transmission efficiency, component flexibility, and EMC anti-interference capabilities increase, the replacement and localization of this model has important engineering and supply chain value.

Why do 2. need a replacement?

2.1. Supply risk and delivery uncertainty:

The lead time of standard parts suppliers is long (for example, the official standard lead time can be several weeks).

In high-volume manufacturing or iterative development, delivery fluctuations directly affect delivery schedules.

2.2, cost control and local manufacturing capabilities:

For high-density harness assemblies, high-quality manufacturing process control can significantly impact overall cost and consistency. Producing equivalent alternatives through an own/co-manufacturing system helps to control costs and shorten the supply chain path.

2.3, customized electrical or mechanical requirements:

In some custom product designs, there may be additional requirements for length, shielding or pressure adaptation, which are difficult to achieve in standard components.
