Edgeboard Connectors Procurement Notes

Verify the specific position count against project requirements, as datasheet references vary between 62 and 72 positions for this series code. Confirm the mating board thickness tolerance aligns with the 1.57 mm specification. Ensure the gold plating grade meets environmental durability standards for the intended operational lifespan. Cross-reference the manufacturer part number with distributor catalogs to confirm availability and lead times prior to finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface is required for systems utilizing 1.57 mm thick circuit boards. The 3.96 mm pitch accommodates standard trace widths while maintaining compact form factors. Verify that the 5 A current rating satisfies the power distribution needs of the connected modules. Consider the straight mounting style for direct panel or chassis integration without requiring angled adapters.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by robust construction suitable for demanding environments. Similar variants in the lineup differ primarily in position counts and row configurations, allowing for scalable design solutions across various electronic hardware platforms requiring reliable vertical or horizontal board connections.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include EDAC part numbers within the same 305 series family that match the 3.96 mm pitch and 1.57 mm board thickness specifications. Ensure any replacement maintains the dual-row receptacle format and gold-plated contact finish to preserve electrical continuity and mechanical compatibility.
