Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm exact contact configuration and plating specifications. Ensure compatibility with the target PCB stack-up and hole dimensions before procurement. Confirm RoHS compliance status through the manufacturer's latest documentation to meet regulatory requirements for your specific application region.

Edgeboard Connectors Selection Notes

Select this component when a vertical, single-edge connector with a 3.96 mm pitch is required. It is suitable for applications needing 27 signal paths with high durability. Consider the 1.57 mm PCB thickness constraint during mechanical design. Verify that the solder pin termination aligns with your assembly process capabilities and thermal profile requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 357 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and mounting styles. The 357-027-558-103 specifically addresses the need for mid-range density connections with reliable gold-contact performance in vertical configurations.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts like 357-028-545-101 or 357-010-527-103, provided the position count matches the design requirement. Always cross-reference the dimensional drawings and electrical ratings before swapping components to ensure mechanical fit and functional equivalence.
