Procurement Notes
Verify the specific pin count and contact spacing against the official datasheet before procurement. Confirm that the target PCB thickness falls within the specified operational range of 0.054 to 0.070 inches. Ensure compatibility with the required operating temperature environment. Check for any specific RoHS compliance requirements mandated by the end application standards.
Selection Notes
Select this connector when a high-density dual-edge interface with 0.156-inch spacing is required. It is suitable for applications demanding robust mechanical stability through panel mounting. Consider the gold plating for corrosion resistance in harsh environments. Evaluate the thermal performance limits against the system's operational heat profile.
Part Context
This component belongs to the EDAC 306 series of card edge connectors. The series is characterized by its use of cantilever spring contacts and durable thermoplastic insulation. These connectors are engineered for high-reliability applications requiring secure board-to-board or board-to-backplane connections.
Replacement Considerations
Direct substitutes include other EDAC 306 series variants with matching 56-position counts and 0.156-inch pitch. Verify mechanical dimensions and electrical ratings before substitution. Cross-reference with manufacturer cross-indexing guides for equivalent components.
