Procurement Notes
Verify the specific ordering suffix against official EDAC documentation to confirm material composition and plating specifications. Ensure compatibility with target PCB dimensions before procurement. Confirm RoHS compliance status through the manufacturer's latest datasheet or product compliance reports prior to finalizing supply chain agreements.
Selection Notes
Select this component when a vertical, panel-mountable card edge interface is required for high-density applications. The 3.96 mm pitch suits designs needing robust mechanical retention for dual-edge cards. Verify that the operating environment remains within the specified thermal limits and that the board thickness matches the connector's acceptance criteria.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors. The series provides interconnect solutions for rack and panel applications across computing, medical, and industrial sectors. EDAC manufactures these components to meet rigorous quality standards for global distribution channels and OEM integration requirements.
Replacement Considerations
Consult official EDAC substitution guides for verified alternative part numbers. Do not assume cross-compatibility with other manufacturers' products without verifying pinout, pitch, and mechanical envelope alignment.
