USB-C Receptacle for High-Durability Applications
The Hirose CX90B-16P is a USB-C (USB TYPE-C) receptacle from the CX series, carrying 24 contacts arranged as 16 signal plus 8 dummy positions. It is rated for 5A at 20VAC, making it suitable for power delivery alongside USB 2.0 data rates. The 10,000 mating cycle rating is the standout feature here — this is not a typical consumer-grade USB port; it is built for repeated connect/disconnect duty in industrial or field-service equipment where a standard USB-C would wear out after a few hundred cycles.
This receptacle supports both Surface Mount, Right Angle and Through Hole mounting — the dual option lets a board layout engineer choose reflow assembly for the SMD version or a more robust through-hole anchor for vibration-prone environments. Termination is solder-only; no press-fit option here.
Shielding and Environmental Ratings
The shell is shielded with Steel, Stainless material, providing EMI containment for passing radiated emissions testing.
Positioning Against the CX90B1-24P
The sibling CX90B1-24P is a USB 3.2 Gen 2 (10 Gbps) version of the same receptacle, also with 24 contacts. The CX90B-16P is limited to USB 2.0 (480 Mbps), so the decision between them comes down to data rate requirement: if your design needs SuperSpeed+, go with the CX90B1-24P; if USB 2.0 is sufficient, the CX90B-16P is the lower-cost option with the same mechanical footprint and 5A power rating.
