Procurement Notes

Verify the complete part number 306-028-500-112 against manufacturer datasheets to confirm compatibility with specific board thicknesses and mounting requirements. Ensure that the procurement channel provides original EDAC Inc. products to guarantee RoHS compliance and material specifications. Cross-reference the ordering guide for the 306 series to validate pin count and spacing parameters before finalizing orders.

Selection Notes

Select this component when a dual-edge female connector with a 0.156-inch pitch is required for panel-mounted applications. The 56-position capacity suits designs needing substantial I/O density within a compact footprint. Consider the cantilever contact type for ease of insertion and removal during maintenance or module replacement scenarios in medical or industrial environments.

Part Context

This connector belongs to the EDAC 306 series, which specializes in card edge connectors with 0.156-inch spacing. The series offers various position counts and termination styles, catering to diverse electronic assembly needs. The 306-028 variant specifically addresses applications requiring 28 positions per row, balancing connectivity density with mechanical stability for standard PCB implementations.

Replacement Considerations

Consult the official EDAC 306, 316, and 356 Series Ordering Guide for verified substitute part numbers. Direct replacements must match the 0.156-inch pitch, 56-position count, and dual-edge female configuration to ensure mechanical and electrical compatibility without redesigning the host panel.
