Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating thickness and insulation color specifications. Ensure compatibility with the target PCB card thickness range of 1.37 mm to 1.78 mm. Confirm that the vertical panel mounting style aligns with the mechanical enclosure design requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required. The 5 A current rating and wide operating temperature range make it suitable for demanding environments. Verify that the solder pin termination method matches the assembly process capabilities and that the panel mount orientation fits the system chassis constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options, including panel and board edge styles. The 305 series is characterized by its use of thermoplastic materials and gold-plated contacts, providing a balance of performance and reliability for general-purpose electronic interconnection needs.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-050-556-201 or 305-054-556-278 if different position counts are needed. Ensure any substitute maintains the same 3.96 mm pitch and dual-row configuration to preserve mechanical and electrical compatibility.
