Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact contact configuration and flange specifications. Ensure compatibility with target PCB thickness ranges before procurement. Cross-reference RoHS compliance status with current regulatory requirements. Confirm availability through authorized distributors as supply chains may vary. Validate mechanical dimensions against enclosure constraints.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required. Consider the 5 A current rating and temperature range for environmental suitability. Verify that the target application supports panel mounting and vertical orientation. Compare alternative positions within the 305 series if different pin counts are needed. Ensure the gold plating meets corrosion resistance standards for the operating environment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by vertical panel mount headers with solder lug termination. These connectors are engineered for durability and consistent electrical performance in demanding industrial environments. The 305 series provides various position counts and flange options to suit diverse board integration needs.

Edgeboard Connectors Replacement Considerations

Consult EDAC official substitution guides for direct replacements. Verify identical pitch, position count, and contact type for functional equivalence. Check mechanical fitment and electrical ratings before substituting.
