USB-C (USB TYPE-C) USB 2.0 Receptacle Connector 24 (16+8 Dummy) Position Board Edge, Cutout; Surface Mount; Through Hole, Right Angle
The USB4520-03-0-A from Global Connector Technology (GCT) is a mid-mount USB Type-C connector that supports USB 2.0 signaling. It is engineered for space-saving PCB layouts, combining both surface-mount and through-hole (hybrid) mounting for improved mechanical strength and reliability.
It features a right-angle, board-edge design, making it suitable for devices where the USB-C port needs to be accessible from the edge of the enclosure.
Electrical & Interface
USB Type-C receptacle (female)
Supports USB 2.0 data transfer
24 total positions (16 active + 8 dummy pins) for mechanical compatibility
Reversible plug orientation (standard USB-C feature)
Mechanical Design
Mid-mount (mid-plane) design → partially recessed into PCB for lower profile
Right-angle orientation for edge-mounted applications
Hybrid mounting:
Surface-mount signal pins
Through-hole shell tabs for mechanical reinforcement
Designed for board-edge cutout integration
Form Factor & Durability
Compact footprint for space-constrained designs
Robust retention due to through-hole anchor tabs
Typically rated for thousands of mating cycles (standard for USB-C connectors)
Application Use Cases
Embedded systems (e.g., ESP32-based boards)
Consumer electronics (chargers, hubs, IoT devices)
Industrial control interfaces
Portable devices requiring USB-C power/data
Design Notes (Important for PCB Layout)
Requires PCB cutout for mid-mount placement
Pay attention to:
Keepout zones under the connector
Differential pair routing (D+ / D−) for USB 2.0
Ensure proper mechanical anchoring to avoid stress on SMT pads
