Edgeboard Connectors Procurement Notes
Verify the specific ordering suffix against the manufacturer's current 306 Series Ordering Guide to confirm exact pin count, plating thickness, and flange specifications. Ensure compatibility with the target PCB thickness range of 0.054 to 0.070 inches before finalizing procurement orders.
Edgeboard Connectors Selection Notes
Select this component when a robust, high-current capable connection is required for double-sided edge cards. The 0.156-inch pitch accommodates larger traces compared to finer pitches, while the panel mount style provides mechanical stability superior to board-edge variants.
Edgeboard Connectors Part Context
This part belongs to the EDAC 306 Series, which specializes in standard card edge connectors. The series offers various configurations for different board thicknesses and mounting styles, utilizing durable thermoplastic polyester insulators and gold-plated contacts for long-term reliability.
Edgeboard Connectors Replacement Considerations
Consult the official EDAC 306 Series cross-reference documentation for verified substitute part numbers. Ensure any replacement maintains the same 0.156-inch pitch, 36-position count, and dual-edge female interface requirements.
