Procurement Notes
Verify the specific ordering suffix against official EDAC documentation to confirm exact plating thickness, flange characteristics, and termination style. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS compliance status through current manufacturer datasheets as regulatory requirements may evolve.
Selection Notes
Select this component when a dual-row, 54-position connection is required with a 3.96 mm pitch. Verify that the target application supports panel mounting and operates within the specified thermal range. Ensure the mating card thickness falls within the 1.37 mm to 1.78 mm acceptance window for proper mechanical engagement.
Part Context
This part belongs to the EDAC 306 series, which provides a wide range of card edge connectors for rack and panel applications. The series is known for offering diverse mounting options and contact terminations. EDAC has been a leader in interconnect solutions since 1966, serving global OEMs in computing, medical, and aerospace sectors.
Replacement Considerations
Cross-reference with other EDAC 306 series variants such as 306-027-521-112 for potential pinout or flange differences. Verify dimensional drawings against existing chassis constraints. No direct third-party substitutes are confirmed; consult EDAC for equivalent part numbers with modified specifications.
