What we stock and why it matters
From USB Type-A/Type-C, HDMI, DisplayPort and Ethernet RJ45, to internal headers (SATA, M.2, PCIe riser connectors), power jacks and board-to-board pin headers - having the right mating geometry and current rating prevents failed builds. We highlight stock depth by category so you can select parts that fit both hobby PCBs and industrial control racks.
- External I/O: USB, HDMI, DisplayPort, RJ45
- Internal storage and expansion: SATA, M.2, PCIe
- Power and DC jacks, barrel connectors and Molex-style power
- Headers and sockets: pin headers, IDC, FFC/FPC, board-to-board
Specification callouts you should check
When choosing a connector, verify mechanical fit, electrical ratings and cable assembly options. Key specs include contact finish (e.g., gold flash), pitch (mm), current rating (A), mating cycles, and keyed vs. unkeyed housings. For quick comparison, use our Collections to filter by category and pitch so you avoid returns and rework.
Explore product ranges and filter by specification on our Collections or browse everything in one place on All Products to compare part families.
Compatibility guidance - practical rules
Match pitch and pin count first. Use physical mating diagrams where available; for cable assemblies, check whether strain relief and shielding are present. When adapting between standards (for example, USB Type-C to legacy Type-A), choose a verified adapter or breakout with clear pin mapping to avoid power or data faults.
