Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required polarizing keys and board thickness specifications. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Cross-reference the part number with the latest revision history to avoid discrepancies in dimensional tolerances or material compositions.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection is required for double-sided cards. Ensure the mating card edge thickness falls within the specified tolerance of 1.57 mm. Consider the 5 A current rating and operating temperature limits for thermal management. Verify that the straight mounting angle aligns with the mechanical layout constraints of the target printed circuit board assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations to accommodate different interface requirements. The 305 series is characterized by its robust construction and suitability for general-purpose electronic applications requiring secure board-to-board or board-to-backplane connections.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for alternative part numbers with differing position counts or contact plating options. Direct substitutes must maintain identical pitch, row count, and mounting style to ensure mechanical fit.
