The I-PEX CABLINE®-CAL series adopts a 0.4mm pitch, horizontal mating structure with a mating height of 0.73±0.07mm, supports 30Pin and 40Pin, and is compatible with Micro-Coaxial Cable such as AWG38, AWG40, AWG42, AWG44, and is suitable for internal connections in thin, high-speed equipment. The official product page positions CABLINE®-CAL as low-space connection and high-speed transmission applications at 40Gbps/lane PAM3. Among them, I-PEX 82998-100B-01-D is a 30Pin ultra-thin coaxial cable assembly that uses AWG#40, 50Ω Micro-Coax with a nominal length of 100MM, and an actual length tolerance of 100±5mm, using a 1-1 straight-line sequence at both ends; the connector housing model used at the wire material end is 20777-030T-01. For engineers, these parameters determine the basic mechanical installation, electrical performance, and signal transmission of the cable assembly; for purchasers, part numbers, connectors, wire diameter, length, and line sequence are important basis for confirming whether the alternative products truly match.
The extremely thin coaxial cable bundle experiences breakage, which usually requires analysis from three aspects: the cable material itself, the termination area, and the assembly stress, rather than simply attributing it to the thinness of the cable. For cables like 82998-100B-01-D composed of 30 AWG#40 Micro-Coax, during the production and assembly process, if there is repeated bending at the cable root, excessive pulling, or unreasonable fixation, it may cause local long-term mechanical stress, increasing the risk of breakage. Therefore, in the production process, it is necessary to control the stripping, termination, shaping, and Bonding processes to avoid damaging the extremely thin coaxial cables; during equipment assembly, it should be avoided to have sharp bends, excessive tension, or local compression near the connectors. The engineering drawing of 82998-100B-01-D itself also clearly designs the Bonding area, uses UV Glue for related fixation, and sorts the cable bundle with black Acetate Tape. These structures need to maintain reasonable process consistency during compatible alternative production.
For engineers, improving the problem of broken fine coaxial cable bundles cannot rely solely on外观 inspection, but should also be judged by a complete reliability verification to determine whether the cable bundle has potential failure. 82998-100B-01-D adopts 1-1 wire sequence, that is, Connector 1 Pin 1 corresponds to Connector 2 Pin 1, up to Pin 30 corresponding to Pin 30, so after production, it is first necessary to confirm 30 lines of conduction and the accuracy of the wire sequence; at the same time, check the assembly status of 20777-030T-01 Housing, Shell and Lock Bar to avoid abnormal stress on the connector area. CABLINE®-CAL adopts mechanical clamps, and the official instructions state that the clamps can only be locked when the male and female sockets are completely fitted together, which can reduce the risk of half-fit and connector ejection. For high-speed applications, signal integrity indicators such as impedance, insertion loss, return loss, and crosstalk should also be verified in combination with the actual system requirements. It should be particularly noted that the high-speed test conditions of the official product page of CABLINE®-CAL are AWG#40, 45Ω, 100mm, while the wire impedance specified in the specific engineering drawings of 82998-100B-01-D is 50Ω, so when replacing and developing, the specific cable specification and the customer's actual system requirements should be matched, rather than simply using the test conditions from the connector page.
For purchasers seeking compatible replacement cables for the 82998-100B-01-D, it is recommended not to provide vague information such as "I-PEX 30Pin cable" but to fully confirm the core specifications such as CABLINE®-CAL series, 30Pin, 20777-030T-01 Housing, AWG#40 Micro-Coax, 50Ω, 100MM, 1-1 wire sequence, and to check the connector structure, cable exit method, termination quality, and actual installation dimensions. The official I-PEX model page explicitly lists the 82998-100B-01-D as a CABLINE-CAL 30Pin, 40AWG, 100mm, 1-1 sample evaluation cable. For engineering verification, attention should also be paid to the stability of the cable after bending, the mechanical strength of the termination area, and the high-speed signal performance. Our company can provide: I-PEX 82998-100B-01-D compatible replacement cable solutions, which can produce ultra-thin coaxial cables that match the requirements of 20777-030T-01, AWG#40, 50Ω, 100MM, 30Pin, 1-1, etc., according to the customer's original specifications, and provide corresponding cable products for sample verification, domestic substitution, and bulk procurement.
