I-PEX 83013-100B-01-D CABLINE®-SS 40AWG/50Ω series ultra-thin coaxial cable replacement

20PIN+0.4MM ultra-fine pitch, balancing high-speed signals and compact space layout
In high-speed camera, display module, AI vision equipment, and notebook internal connections, engineers often need to simultaneously complete the transmission of high-speed differential signals and power in limited spaces. This poses higher requirements for the size, impedance, shielding, wire sequence, and connector reliability of the harness. The I-PEX CABLINE®-SS adopts a 0.4mm pin spacing, vertical right-angle insertion and extraction, and horizontal out-line structure, combined with a narrower connector structure, which can be used for internal connections of high-speed equipment with limited space. Official product documentation indicates that this series supports 10, 14, 20, 30, 32, 35, 40, and 50 Pin specifications and has the high-speed transmission positioning of up to 16Gbps/Lane.

The specific product introduced this time is I-PEX 83013-100B-01-D, which belongs to CABLINE®-SS 20PIN, 100mm, 1-1 sequence ultra-thin coaxial cable bundle. It uses AWG#40 Micro-Coaxial Cable, and the cable characteristic impedance is marked as 50Ω in the PDF. The connector model used at the cable end is 20373-R20T-06, with a 20PIN, 0.4MM spacing, matching the corresponding CABLINE®-SS structure. For engineers, the value of this design is not only in "thinner wire diameter" but more importantly, it can combine high-speed signal connection with internal space design of the device, providing a compact wiring solution for applications such as cameras, displays, AI vision modules, etc.

How to achieve "dual differential + power combination" in extremely fine coaxial beam?
The so-called "dual-channel differential + power combination" is not simply about placing two sets of signal and power lines into the same cable bundle. Instead, it involves reasonable planning of high-speed differential channels, reference/shielding paths, and power and ground lines within a limited number of pins. For camera systems using MIPI CSI-2, CSI-2 typically operates on the physical layer of MIPI D-PHY or C-PHY, among others. D-PHY uses two-wire differential data lanes and can be configured with one clock lane. Therefore, when the system requires two high-speed differential data channels, the cable bundle needs to be allocated according to the specific PHY, the number of lanes, and the system schematic.

In actual harness design, high-speed differential signals can be prioritized to be arranged in paired, adjacent, and symmetric signal channels based on the system Pin definition, while combining GND or shielding structures to reduce crosstalk. The remaining available Pins are then configured for power and ground lines according to the power requirements of the camera module, sensor, or display module. It is particularly important to note that 20PIN does not necessarily mean a fixed definition of "2 groups of differential + some power". The actual Pin Assignment must be confirmed based on the customer's schematic and interface definition, and cannot be inferred solely from the number of connector Pins. For high-speed channels, it is also necessary to focus on controlling differential impedance, pair consistency, length matching, return loss, insertion loss, crosstalk, and connector termination quality to ensure signal integrity. The MIPI official documentation also emphasizes the high-speed, low-power consumption, and low-EMI characteristics of CSI-2, therefore, the harness cannot only focus on conduction but also needs to be verified from the perspective of the entire high-speed link.

83013-100B-01-D: Combine high-speed signals, wiring sequence, and connection reliability
The core specifications of I-PEX 83013-100B-01-D include 20P, 100.0±5.0mm, 1-1 wire sequence, AWG#40 Micro-Coaxial Cable, and 50Ω cable impedance; the corresponding material end connector is 20373-R20T-06, 20PIN, 0.4MM. From the perspective of engineering applications, the 1-1 wire sequence allows for direct connection between corresponding pins at both ends, which is more suitable for designs that require clear end-to-end signal correspondence; if the customer's system uses a different Lane arrangement or requires cross-definition, it must be reconfirmed according to the schematic, PCB Pin definition, and connector orientation. The I-PEX CABLINE®-SS itself also adopts the W-Point dual-contact design and supports AWG36, AWG38, AWG40, AWG42 Micro-Coaxial Cable, as well as AWG34, AWG36 Discrete Wire, where the thicker specifications can be used in scenarios requiring higher current capacity.

Here it is necessary to remind engineers and procurement personnel: The high-speed performance verification conditions provided on the I-PEX product page are CABLINE®-SS 40P, AWG#40 Micro-Coaxial Cable, 45Ω, 100mm, GSSGSSG, for verifying its high-speed transmission capability; while the specific PDF marking for this 83013-100B-01-D is 50Ω AWG#40 cable. Therefore, when designing alternatives for MIPI CSI-2, display signals, or other high-speed interfaces, the actual link impedance, PHY requirements, and SI test results of the target device should be used as a basis, and the 45Ω test conditions should not be directly considered as the cable specifications for 83013-100B-01-D.

Selection and compatibility with alternative solutions reference and suggestions
For engineers, it is recommended to first confirm the connector series, pin count, pitch, wire exit direction, wire sequence, and wire length when selecting, and then further confirm the Micro-Coax specifications, impedance, shielding structure, and high-speed signal requirements; for purchasers, the specific Harness Part Number should be used as an important basis for quotation and material confirmation, rather than simply writing "CABLINE-SS 20P ultra-fine coaxial cable". For example, this scheme should clearly correspond to I-PEX 83013-100B-01-D, 20373-R20T-06, 20PIN, 0.4MM, 100mm, 1-1, AWG#40, and other key conditions. The I-PEX official page also lists the 20P 1-1 cable sets 83013/83014/83015 and 1-N cable sets 82883/82069/82884, so it is particularly important to avoid mixing the 1-1 and 1-N models when purchasing alternatives.

In the development process of domestic compatibility and replacement, in addition to the physical matching of connectors, it is also necessary to focus on verifying the quality of terminal crimping, cable impedance consistency, differential pair length and structural consistency, shielding continuity, insertion and extraction reliability, and high-speed SI performance. For "dual differential + power supply" applications, it is also necessary to determine the specific allocation of power lines, GND, and high-speed differential channels according to the actual Pin definition of customers, and optimize them in combination with the whole machine test results. Our company can provide: I-PEX 83013-100B-01-D compatibility and replacement cable solution, which can be developed for compatibility and replacement around 20PIN, 0.4MM connector, AWG#40 ultra-thin coaxial cable, specified length, wire sequence, and customer actual Pin definition, providing ultra-thin coaxial cable assembly manufacturing support for engineers to verify samples and mass production.
