Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, termination style, and flange options. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region.

Edgeboard Connectors Selection Notes

Select this connector when a vertical panel-mount solution with a 3.96 mm pitch is required. Verify that the mating card edge board thickness aligns with the specified 1.57 mm nominal dimension. Consider the 5 A current rating and environmental temperature range to ensure suitability for the intended operational conditions.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which offers various mounting options and configurations for card edge applications.
