USB-C 3.2 Gen 2 Receptacle for High-Density I/O
The Hirose CX90B1-24P is a USB Type-C receptacle from the CX series, carrying the full 24-contact complement for USB 3.2 Gen 2 operation. With a rated 10000 mating cycles, the gold-plated contacts are specced for high-durability ports.
Dual Current Paths and Power Delivery Planning
The current rating splits into two tiers: 0.25 A per contact on the signal pins and 1.25 A per contact on the power pins. This is standard for USB-C — the lower figure covers the high-speed data lines, while the higher figure handles VBUS and GND. For a 20 VAC rated port, the power contacts can deliver up to 5 A total across the four VBUS pins (1.25 A each), which aligns with USB Power Delivery profiles. The steel and stainless shell provides full EMI shielding around the mated interface.
Board Mounting and Reflow Considerations
The mounting feature is listed as both Surface Mount, Right Angle and Through Hole. This typically means the signal pins are SMD for reflow, with through-hole anchor posts for mechanical retention. The horizontal, reversible orientation is inherent to the USB-C form factor — the connector accepts the plug in either flip. Tape & Reel packaging feeds the pick-and-place line directly, with Cut Tape available for prototyping.
Comparing the CX90B1-24P with a USB 2.0 Sibling
The 24 contacts are present (16 signal + 8 dummy), but the SuperSpeed pairs are not wired out. The CX90B1-24P carries the full USB 3.2 Gen 2 signal set, making it the correct choice for any design that needs the 10 Gbps data lanes. If the application is USB 2.0 only, the CX90B-16P saves cost on the unused high-speed contacts.
