Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix matches the required contact spacing and board thickness specifications before procurement. Confirm RoHS compliance status and environmental certifications align with project requirements. Ensure the selected variant corresponds to the exact pin count and termination style needed for the target PCB layout. Cross-reference manufacturer documentation for any recent design changes or obsolescence notices.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 0.156-inch pitch is required for 0.062-inch thick boards. Consider the vertical mounting orientation and panel-mount flange characteristics for mechanical integration. Evaluate the thermal operating range and insulation material properties against environmental conditions. Compare alternative part numbers in the 305 series if different pin counts or spacing options are necessary.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series of standard card edge connectors. The series offers various configurations with consistent 0.156-inch spacing. Similar models include the 305-050-556-502 and 305-054-556-278, which share comparable structural designs but differ in position count and specific termination details. The 305 series is widely used in applications requiring robust, high-density interconnect solutions.
