Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC channels or certified distributors. Confirm RoHS compliance status and specific lot traceability requirements against project specifications. Ensure storage conditions maintain material integrity prior to assembly. Cross-reference ordering suffixes to confirm exact pin count and termination style matches the required design parameters.

Edgeboard Connectors Selection Notes

Select this model when a dual-row, 26-position interface is required with a 3.96 mm pitch. Verify that the target PCB thickness falls within the 1.37 mm to 1.78 mm acceptance range. Ensure the application environment remains within the specified -40°C to +105°C operating limits. Confirm that the 5 A current rating meets the electrical load requirements of the connected circuitry.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options while maintaining consistent dimensional standards. These connectors are engineered for high-reliability applications requiring robust mechanical retention and stable electrical performance across diverse industrial environments.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series variants with matching 26-position layouts and 3.96 mm pitch. Verify that alternative part numbers support identical panel mount styles and dual-edge configurations. Ensure thermal and electrical ratings align with original design constraints before substitution.
