Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm terminal type and mounting style. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm RoHS compliance status if required by project specifications. Cross-reference the Mouser part number 587-305-082-555-508 for accurate sourcing details. Check regional availability as distribution may vary.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 3.96 mm pitch is required. The 82-position count suits applications needing extensive I/O in a compact footprint. Surface mount termination is ideal for automated assembly processes. Verify that the 5 A current rating meets the system's power requirements. Ensure the operating temperature range aligns with the environmental conditions of the final assembly.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which offers various positioning options and mounting styles. The series is characterized by its standardized 3.96 mm contact spacing and durable construction. The 305-082-555-508 variant specifically addresses needs for high-pin-count interfaces in space-constrained electronic designs. It complements other components in the same family by providing consistent mechanical and electrical standards across different position counts.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include models with identical pitch and row configuration but different pin counts, such as 305-050-555-508. For equivalent specifications from other manufacturers, verify matching 3.96 mm pitch, dual-row layout, and surface mount termination. Ensure thermal and current ratings are comparable before substitution.
