Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm flange characteristics and termination style, as variations exist within the 305 series. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure that the selected variant matches the required PCB thickness tolerance of 1.37mm to 1.78mm for proper mechanical engagement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 3.96mm pitch is required for panel-mount applications. The 28-position count suits moderate-density signal routing needs. Verify compatibility with polarizing key requirements if board retention against rotation is necessary. Ensure the operating temperature range of -40°C to +105°C meets environmental constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and flange options to accommodate different board densities and mounting styles. The 305-028-521-507 specifically represents a 28-position variant with defined termination and housing characteristics within this standardized product line.
