Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official catalog to ensure compatibility with required PCB thickness and flange specifications. Confirm RoHS compliance status and moisture sensitivity levels prior to integration into production workflows. Cross-reference the datasheet drawing for precise dimensional tolerances to guarantee mechanical fit within the target enclosure design.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 0.156-inch pitch is required for vertical panel mounting. Ensure the target printed circuit board thickness falls within the specified operational range of 0.054 to 0.070 inches. Consider the gold plating finish for applications demanding high corrosion resistance and stable electrical performance over extended service life cycles.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series, which encompasses a broad range of standard card edge connectors. The series is characterized by its versatility in accommodating various contact counts and board thicknesses while maintaining consistent interface standards. It serves as a foundational interconnect solution for general-purpose electronic systems requiring durable and standardized board-to-board or board-to-panel connections.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305/315/355 Series Ordering Guide for verified substitute part numbers. Direct replacements must match the 48-position count, 0.156-inch pitch, and dual-edge female configuration. Verify that alternative parts maintain identical termination styles and mounting characteristics to ensure seamless integration without redesigning the host assembly.
