Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official ordering guide to confirm exact termination style, plating thickness, and flange options. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm RoHS compliance status through the latest datasheet revision. Cross-reference the Mouser or DigiKey part numbers for accurate sourcing channels. Validate that the panel mounting requirements match the physical dimensions provided in the dimensional drawing.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is required for high-density signal routing. The 3.96 mm pitch suits applications where board space allows wider spacing compared to finer pitches. Verify that the 5 A current rating meets the circuit load requirements. Consider the vertical panel mount style if chassis integration is necessary. Ensure the operating temperature range aligns with the environmental conditions of the final assembly.
