Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 28-position count and single-row configuration. Confirm that the operating temperature range of -40°C to +105°C aligns with the environmental conditions of the target application. Ensure compatibility with the intended PCB thickness and mounting style before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this connector when a single-edge interface with 28 positions is required. Consider the 0.100 inch pitch for standard spacing needs. Evaluate the thermal performance requirements against the +105°C maximum limit. Choose this variant if gold plating is necessary for corrosion resistance and low contact impedance in the specific circuit environment.

Edgeboard Connectors Part Context

This component belongs to the EDAC 345 series of edgeboard connectors. The series typically includes various position counts and row configurations. The 345-028-520-188 specifically denotes the 28-position single-edge variant. It shares design characteristics with other models in the family but differs in pin count and specific housing attributes.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC single-edge connectors with identical 28-position layouts and 0.100 inch pitch. Verify mechanical dimensions and contact plating specifications when considering alternative manufacturers. Ensure that any replacement maintains the same current rating and temperature tolerance.
