Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC 305 Series Ordering Guide to ensure correct contact plating, insulation material, and mounting style. Confirm that the polarizing key requirements match the application design. Check RoHS compliance status as specified in the manufacturer documentation before final procurement.

Edgeboard Connectors Selection Notes

Select this model when a 72-position dual-edge interface is required with a standard 0.156-inch pitch. Ensure the target PCB thickness falls within the 0.054 to 0.070-inch range for proper mechanical engagement. Consider the need for polarizing keys if anti-mating protection is necessary for the assembly.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting configurations. The 305-072-555-502 specifically denotes a 72-position female receptacle designed for robust industrial and commercial electronic applications requiring high reliability.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with identical electrical and mechanical specifications. Verify compatibility with existing polarizing key designs and PCB footprint dimensions before substitution.
