Procurement Notes
Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB edge thickness of 1.57 mm before procurement. Confirm that the vertical panel mount orientation aligns with the mechanical design constraints of the final assembly enclosure.
Selection Notes
Select this component when a dual-edge female connector with 56 positions is required for vertical panel mounting. The 0.156-inch pitch and gold-plated contacts suit applications needing high reliability and moderate current capacity. Verify that the thermoplastic housing material meets the environmental requirements of the intended operating conditions.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors. The series provides various position counts and termination options. The 306-028-520-101 specifically utilizes the 028 code indicating the 56-position variant within this standardized product line.
Replacement Considerations
Consult official EDAC substitution guides for direct equivalents. Cross-reference pin counts and pitch dimensions carefully. Verify that any alternative maintains the dual female configuration and vertical mounting style.
