Procurement Notes
Verify the specific ordering suffix against official EDAC documentation to confirm exact plating thickness, housing color, and termination type. Ensure compatibility with target PCB edge thickness specifications before procurement. Confirm RoHS compliance status through current manufacturer declarations. Cross-reference part numbers with authorized distributors to avoid counterfeit components.
Selection Notes
Select this connector when a dual-edge female interface with a 3.96 mm pitch is required for vertical panel mounting. Evaluate thermal requirements against the -55°C to +85°C operating range. Consider the 50-position count for circuit density needs. Verify that the target printed circuit board edge thickness falls within the specified 1.30 mm to 1.80 mm acceptance window for proper contact engagement.
Part Context
This component belongs to the EDAC 306 Series of standard card edge connectors. The series offers various position counts and pitch options for diverse interconnection needs. The 306-025-520-158 variant specifically addresses applications requiring dual-edge female contacts with a 3.96 mm spacing. It serves as a robust solution for connecting edge-board modules in structured electronic assemblies.
Replacement Considerations
Consult EDAC official substitution guides for compatible alternatives within the 306 Series or other EDAC connector families. Verify mechanical dimensions, electrical ratings, and mounting configurations match before substituting. Generic equivalents may lack precise fitment or performance characteristics.
