Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact pin count, contact finish, and mounting style variations. Ensure compatibility with target PCB thickness and mating card dimensions before finalizing procurement orders. Cross-reference manufacturer part numbers to avoid substitution errors in critical assemblies.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge connection strategy is required for structural integrity. The 3.96 mm pitch accommodates thicker circuit boards compared to finer pitches. Verify that the 5 A current rating meets the system's electrical load requirements and that the green thermoplastic housing aligns with environmental constraints.
