One, from the material number to understand the I-PEX 82874-100B-02-D ultra-fine coaxial cable assembly
For laptop display modules, thin display devices, high-speed camera modules, and other electronic products with high requirements for internal space and high-speed signal transmission, the selection of extremely thin coaxial cable assemblies cannot be solely based on "how many PINs, how many millimeters long." It is necessary to simultaneously confirm key parameters such as connectors, cable specifications, impedance, Pin definition, cable length, and termination structure. The I-PEX 82874-100B-02-D introduced in this article belongs to the I-PEX CABLINE®-CAL series 30 Pin extremely thin coaxial cable assembly. The official sample materials clearly define it as 30 Pin, 40AWG Micro-Coaxial, L=300 mm, 1-N structure. Its matching cable end connector is I-PEX 20777-030T-01, with a connector of 30 PIN, 0.4 mm Pitch. The CABLINE-CAL official materials also show that this series uses a horizontal insertion structure, with Mated Height of 0.73 ±0.07 mm, supporting AWG38, AWG40, AWG42, and AWG44 Micro-Coaxial Cable. For engineers and procurement personnel who need to carry out domestication, second supplier introduction, or replacement of existing cable assemblies, what is truly important is to establish a method of confirming complete cable specifications from "original factory part number," rather than merely finding similar products based on the appearance of the connector.

How to confirm the specifications of ultra-fine coaxial cable束? What parameters should engineers and purchasing personnel focus on?
When confirming the specifications of a very thin coaxial cable assembly, it is recommended to first lock in several core pieces of information: "Connector Model + Pin Count + Pitch + Wire Material AWG + Length + Pin Assignment", and then further confirm impedance and high-speed signal requirements. Taking 82874-100B-02-D as an example, first confirm that the connector end uses 20777-030T-01, with a Pin count of 30 PIN and a Contact Pitch of 0.4 mm; next, confirm that the cable is a Micro-Coaxial Cable with a specification of 40AWG, rather than just written as "extremely thin coaxial cable". I-PEX official documents clearly show that CABLINE-CAL supports Micro-Coaxial Cable with AWG38, AWG40, AWG42, AWG44, etc., and the publicly released 82874 evaluation cable explicitly uses 40AWG. Further confirmation requires checking the cable length, cable exit form, and the correspondence between the Pins at both ends; I-PEX official documents list 82874 as L=300 mm, 1-N structure, while the same series also exists 82998, 82999, 83000, etc., 30 Pin 1-1 structure models, so even if the Pin count and cable length are the same, they cannot be directly considered as the same type of cable. For high-speed applications, it is also necessary to further confirm characteristic impedance, insertion loss, return loss, crosstalk, and signal integrity requirements. Pay special attention to the high-speed test conditions used in the official CABLINE-CAL product details, which are 30P, AWG40 Micro-Coaxial, 45Ω, 100 mm test combination, which is the official reference test condition; while the specific cable replacement project should still be based on the customer's original drawings, target cable specifications, and actual SI requirements as the final basis.

Three, compatible manufacturing capabilities for engineering substitution: from connectors to overall matching of ultra-fine 40AWG coaxial cable束
For devices or projects that have already adopted the I-PEX 82874-100B-02-D, if you wish to find a stable compatible alternative supply solution, simply purchasing a connector with the same外形 is not enough to complete the replacement. What truly needs to be controlled is the consistency of "connector, cable, termination, Pin Mapping, and overall cable size". Our company specializes in the production and manufacturing of extremely thin coaxial cables and can match cable terminations, process 40AWG Micro-Coaxial cable, assemble terminations, and form cables according to the customer-provided original part number, product drawings, samples, and technical requirements. We can confirm the length, cable exit direction, Pin definition, and structural dimensions for different projects. Our company can provide I-PEX 82874-100B-02-D compatible alternative cable solutions. For this model, during engineering evaluation, the focus should be on the specifications of the 20777-030T-01 connector, 30 PIN, 0.4 mm Pitch, 40AWG Micro-Coaxial, 300 mm cable length, and 1-N connection relationship for specification verification. Further confirmation of impedance and Signal Integrity indicators should be based on the customer's actual high-speed signal requirements. The official I-PEX page also clearly lists the different lengths of 30P 1-N cables such as 82874, 82437, and 82873, as well as other models with 1-1 structure. Therefore, when making inquiries or alternative certifications, the complete part number and structural relationship should be used as the inquiry conditions, rather than just asking for "CABLINE-CAL 30P cable".

Four, selection, compatibility, and alternative solutions reference and suggestions: Do not just look at the connector, the complete specification is the basis for alternative.
For extremely thin coaxial cable assemblies such as I-PEX 82874-100B-02-D, engineers are advised to confirm each item according to the five dimensions of "connector—cable—electrical—structure—application". In terms of the connector, it is necessary to confirm the consistency of I-PEX 20777-030T-01, 30 PIN, and 0.4 mm Pitch; for the cable, it is necessary to confirm the 40AWG Micro-Coaxial Cable, and according to the specific project, confirm the characteristic impedance and high-speed transmission performance; in terms of structure, it is necessary to confirm the 300 mm cable length, cable exit direction, cable assembly fixing method, and 1-N Pin Assignment requirements; in terms of electrical aspects, it should be combined with the actual high-speed interface to confirm insertion loss, return loss, crosstalk, and impedance control, and cannot rely solely on "conduction" as the qualification basis. The I-PEX official CABLINE-CAL data shows that this connector adopts a mechanical locking design, which can only be locked after the male and female connectors are completely mated, and the product has 0.4 mm Pitch, 0.73 ±0.07 mm Mated Height, and 30/40 Pin specifications. Therefore, if customers need to replace the domestic 82874-100B-02-D, introduce a second supplier, or make bulk purchases, it is recommended to first provide the original cable material number, connector model, cable length, AWG, Pin definition, and equipment end interface information, and have the cable manufacturer check the engineering specifications, and then proceed to the sampling, testing, and small batch verification process. For purchasing personnel, this approach also helps to avoid subsequent quality risks due to only comparing unit prices while ignoring the differences in cable material, termination technology, and high-speed performance.

I-PEX 82874-100B-02-D is a CABLINE-CAL series 30P ultra-thin coaxial cable assembly with clear engineering specifications. Its core selection information includes a 20777-030T-01 cable end connector, 30 PIN, 0.4 mm Pitch, 40AWG Micro-Coaxial Cable, 300 mm length, and 1-N structure. Accurately confirming these basic parameters is a prerequisite for connector matching, cable selection, and high-speed signal verification for engineers; for purchasing personnel, it is an important basis for judging whether different suppliers' quotations are truly under the same technical conditions. Our company can provide ultra-thin coaxial cable assembly compatible alternative manufacturing services for this model, and can further confirm the cables, connectors, length, pin definition, and related electrical performance according to the actual project requirements of customers, providing corresponding ultra-thin coaxial cable assembly solutions for customers in need of domestication, alternative supply, or customized development.
