I-PEX 82887-100B-02-D CABLINE®-SS 40AWG/50Ω series ultra-thin coaxial cable replacement

I-PEX 82887-100B-02-D: 32P ultra-fine coaxial cable assembly for high-density, high-speed connections

In notebook computers, tablets, display modules, cameras, and other space-limited electronic devices, high-speed signal transmission not only requires the harness to have good electrical performance but also demands that the connection structure be sufficiently miniaturized to accommodate the increasingly compact internal layout of the devices. The I-PEX CABLINE®-SS series adopts a 0.4mm pin spacing, vertical right-angle insertion and extraction, and horizontal cable exit structure, and supports various pin count specifications, making it suitable for high-density internal connection scenarios. The corresponding ultra-thin coaxial cable product is I-PEX 82887-100B-02-D, which is a 32Pin, 100mm length, 1-N sequence Micro-Coaxial Cable harness. The drawings use AWG#40, 50Ω ultra-thin coaxial wire, and the connector model matched with the wire material is 20373-R32T-06. From the perspective of engineering selection, the connector, wire specification, wire length, and wire sequence need to be matched as a whole to truly achieve a corresponding substitute for the original product.

How to achieve high-speed stable signal transmission for extremely fine coaxial cables?

The stability of high-speed signal transmission does not solely depend on "the thinner the better" or "the connector can be plugged in," but rather on the collaborative control of conductor, insulation layer, shielding structure, characteristic impedance, connector termination, and overall processing consistency. The extremely thin coaxial cable forms a relatively stable transmission environment through the central conductor, insulation layer, shielding layer, and external insulation structure, which can reduce the impact of external interference on high-speed signals; at the same time, the AWG#40 wire material can meet the high-density wiring requirements while maintaining a smaller outer diameter. The high-speed test reference conditions provided on the official I-PEX CABLINE®-SS page use a 40Pin, AWG#40, 45Ω, 100mm Micro-Coaxial Cable, and are tested with GSSGSSG Pin Assignment; while the specific engineering drawings marked as 82887-100B-02-D specify AWG#40, 50Ω wire material. Both belong to different test/product conditions, and engineering development should be based on the actual project drawings and the target system impedance requirements.

From the perspective of engineers and purchasing staff, the replacement harness cannot simply be based on "model the same."

For engineers, when developing a compatible substitute product for the 82887-100B-02-D, it is essential to focus on confirming the 32P structure, the 20373-R32T-06 cable end connector, AWG#40 ultra-thin coaxial cable, 100mm length, 1-N wire sequence, and the actual system's impedance and high-speed signal integrity requirements. According to the official data of I-PEX, CABLINE®-SS can be matched with AWG36, AWG38, AWG40, and AWG42 Micro-Coaxial Cable, where the AWG42 has a characteristic impedance mismatch description; therefore, this model uses AWG#40 with clear engineering matching significance. For procurement personnel, it is necessary to further confirm whether the substitute supplier can stably achieve connector termination, wire sequence, length tolerance, and batch consistency according to the original drawings, rather than just comparing unit price. Our company can provide: 82887-100B-02-D compatible substitute cable harness solution, which can produce ultra-thin coaxial cable harnesses around the original product's connector specifications, cable specifications, wire sequence, size, and application requirements, and provide corresponding domestic substitute and customized cable harness support for customers.

Selection, compatibility, and alternative solutions reference and recommendations

During the actual selection process, if the original design of the equipment corresponds to the I-PEX CABLINE®-SS 32P structure, it is recommended to first confirm the matching relationship between the board-end and cable-end connectors, then confirm whether the 20373-R32T-06 used at the cable-end meets the project requirements, and at the same time, check whether the ultra-fine coaxial cable specification is AWG#40. For high-speed signal applications, it is also necessary to determine the target impedance and signal integrity specifications according to the interface standards of the mainboard, display module, or other terminal equipment, and not simply apply the parameters of other CABLINE series cables. According to I-PEX official data, CABLINE®-SS covers 10P, 14P, 20P, 30P, 32P, 35P, 40P, and 50P, and provides samples of cables with different lengths and 1-N, 1-1 wiring sequences. Therefore, during the replacement development, it is also possible to match them according to the actual Pin count, length, wiring sequence, and wiring space of the equipment. For the procurement side, it is recommended to conduct sample verification before formal mass import, focusing on mechanical fit, electrical performance, high-speed signal integrity, and batch consistency.
