Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm the exact contact plating thickness and housing color variant, as these parameters define the physical characteristics of the component. Ensure that the procurement documentation explicitly references the full part number 305-086-500-278 to avoid substitution errors within the 305 series family. Cross-reference the manufacturer datasheet for precise dimensional tolerances before finalizing supply chain agreements.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 86-position interface is required for panel-mount installations. The 3.96 mm pitch accommodates standard card edge geometries, while the 5 A current rating suits moderate power distribution needs. Confirm compatibility with the target PCB thickness of 1.57 mm and verify that the application environment falls within the specified operating temperature range for thermoplastic materials.
