Edgeboard Connectors Procurement Notes

Verify the specific suffix code against manufacturer documentation to confirm exact housing color and terminal style variations. Confirm RoHS compliance status through official datasheets prior to procurement. Ensure panel cutout dimensions align with the 3.96 mm pitch and 1.57 mm board thickness requirements for proper mechanical fit.

Edgeboard Connectors Selection Notes

Select this component when a 18-position dual-row connection is required with a 3.96 mm spacing. Verify that the target PCB thickness matches the 1.57 mm specification for optimal contact engagement. Consider the vertical mounting style and panel installation method during mechanical design phase to ensure adequate clearance and alignment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts while maintaining consistent 3.96 mm pitch characteristics.
