Edgeboard Connectors Procurement Notes

Verify part number accuracy against official EDAC documentation before ordering. Confirm that the specific suffix matches required specifications, as variations may exist within the series. Ensure compliance with RoHS3 standards if environmental regulations apply to your project. Cross-reference lead times with authorized distributors, as availability may fluctuate based on production schedules. Request updated datasheets to confirm current manufacturing status and any potential obsolescence notices prior to final procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 0.156-inch spacing is required for panel-mounted applications. Consider the 66-position count for adequate I/O density without excessive board space consumption. Evaluate the -40°C to +105°C operating range against your system's thermal profile. Verify that the through-hole termination method aligns with your PCB assembly capabilities. Assess the gold contact finish suitability for your signal integrity requirements and mating cycle expectations compared to alternative finishes.

Edgeboard Connectors Part Context

This connector belongs to EDAC's standard card edge connector lineup, designed for general-purpose electronic interconnections. The 305 series typically features vertical orientation and panel mount styles. It serves as a critical interface between flexible or rigid printed circuits and backplanes or chassis-mounted headers. The product represents a balance of electrical performance and mechanical reliability for commercial and industrial sectors.

Edgeboard Connectors Replacement Considerations

Consult official EDAC substitution guides for verified alternatives. Generic equivalents may not match the precise 0.156-inch pitch or gold plating thickness. Ensure any substitute maintains the same dual female configuration and panel mount constraints. Verify compatibility with existing PCB footprints and mating header dimensions before implementation.
