Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to confirm exact pin count, plating thickness, and mounting style variations. Ensure compatibility with the target PCB edge thickness specifications before procurement. Cross-reference the RoHS compliance status with current regulatory requirements for the intended market. Confirm availability through authorized distributors as supply chain conditions may vary.

Edgeboard Connectors Selection Notes

Select this connector when a vertical panel-mount solution with a 3.96 mm pitch is required. The 28-position capacity suits moderate density applications. Verify that the operating environment stays within the specified -40°C to +105°C range. Ensure the mating card edge thickness falls within the compatible tolerance for the half-beam contact type. Confirm that the solder lug termination method aligns with the assembly process capabilities.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which specializes in standard card edge connectors featuring a consistent 3.96 mm pitch across various position counts. The series provides diverse mounting options including panel and board edge styles. The 305-028-555-508 variant specifically addresses needs for vertical panel integration with solder lug termination, distinguishing it from surface-mount or horizontal variants within the same family.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 Series connectors with matching 3.96 mm pitch and 28 positions, such as 305-028-521-504, provided the mounting style and termination type are verified. Ensure any replacement maintains the same current rating and temperature specifications.
