Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to ensure correct flange and termination specifications. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Cross-reference the part number with the latest datasheet revisions to confirm material composition and environmental ratings before final procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with polarizing key compatibility is required. Ensure the mating PCB thickness falls within the standard acceptance range for the 305 series. Verify that the application environment does not exceed the maximum operating temperature of 105°C. Confirm that the 5A current rating aligns with the circuit design requirements for each contact position.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors. The series is characterized by its robust construction, polarizing key acceptance, and consistent 3.96 mm pitch across various position counts. These connectors are widely used in industrial and commercial applications where reliable, high-current interconnects are necessary.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row count but different position numbers or termination styles. Verify mechanical dimensions and flange characteristics before substitution. No other cross-series replacements are confirmed without detailed engineering review.
