Edgeboard Connectors Procurement Notes
Verify the specific suffix code against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the vertical panel mount style aligns with the mechanical enclosure requirements of the final assembly.
Edgeboard Connectors Selection Notes
Select this component when a high-density 76-position connection is required in a vertical orientation. The 3.96 mm pitch suits applications needing wider spacing compared to standard 2.54 mm headers. Verify that the 5 A current rating meets the electrical load requirements of the circuit design.
Edgeboard Connectors Part Context
This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and mounting styles for dual-edge card connections. The 305-076 variant specifically addresses needs for higher pin counts while maintaining the established 3.96 mm pitch standard.
Edgeboard Connectors Replacement Considerations
Direct substitutes include other EDAC 305 series headers with identical 76 positions and 3.96 mm pitch, such as 305-076-556-508, provided the termination type matches the design.
