Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to ensure correct contact plating, insulator color, and termination type. Confirm that the target PCB design accommodates the required 1.57 mm board thickness and panel-mount footprint. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure availability through authorized distributors as lead times may vary.

Edgeboard Connectors Selection Notes

Select this component when a 74-position dual-row interface is required with a 3.96 mm pitch. Consider the 5 A current rating and -40°C to +105°C operating range for suitability in industrial environments. Verify compatibility with the mating card edge thickness and the available panel-mount orientation. Compare against other 305 series variants if different row counts or termination styles are needed.
