Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to ensure correct pin count, plating thickness, and mounting style. Confirm that the target application requires the specified 0.156-inch pitch and compatible card thickness range. Check current RoHS3 compliance status and lead times directly with authorized distributors or the manufacturer before finalizing procurement plans.

Edgeboard Connectors Selection Notes

Select this connector when a robust dual-row interface is required for double-sided circuit boards. Ensure the design accommodates the 0.156-inch spacing and panel mounting constraints. Verify that the operating environment stays within the -40°C to +105°C range. Consider the 5A current rating and voltage isolation requirements relative to the system architecture before implementation.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options for industrial applications. The 305-034 variant specifically addresses needs for moderate-density connections with high durability.
