Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm plating type and packaging details. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS compliance status matches project requirements. Cross-reference the DigiKey part number for accurate sourcing channels. Validate lead time expectations directly with authorized distributors.
Selection Notes
Select this connector when a dual-edge interface with 68 positions is required. Verify that the 0.156-inch spacing aligns with the target PCB layout constraints. Ensure the through-hole mounting style fits the mechanical assembly design. Confirm that the operating temperature range meets environmental demands. Check insulation material properties against chemical exposure risks.
Part Context
This component belongs to the EDAC 306 series, which offers various configurations for card edge applications. The series supports multiple contact counts and termination styles. It is designed for general-purpose electronic interconnects requiring robust mechanical retention. The product line emphasizes standardized dimensions for broad compatibility.
Replacement Considerations
Consult the official EDAC 306 Series Ordering Guide for verified substitute part numbers. Direct replacements must match position count, spacing, and termination type. Verify housing material and plating specifications for equivalent performance.
