Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to ensure compatibility with required board thickness and termination styles. Confirm RoHS3 compliance status as per current regulatory requirements. Cross-reference the DigiKey part number 151-305-056-555-503 for accurate sourcing identification. Ensure procurement channels provide valid traceability documentation for quality assurance purposes.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge female connector with 56 positions is required for vertical panel applications. Ensure the target PCB thickness aligns with the 0.062-inch nominal specification. Verify that the operating environment remains within the -40°C to +105°C temperature range. Confirm that the 0.156-inch pitch matches the system layout requirements.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, a line of standard card edge connectors. The series offers various position counts and mounting configurations. The 305-056-555-503 variant specifically addresses high-density interconnect needs with its 56-position capacity. It is part of a broader family including similar models like the 305-050-556-502 and 305-048-556-508, differing primarily in pin count and specific interface details.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include the 305-056-555-508, which shares the 56-position count but may differ in termination or flange characteristics. Verify mechanical dimensions and electrical ratings before substitution. Consult the official EDAC ordering guide for cross-referencing compatible alternatives.
