Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm terminal type and plating thickness, as variations exist within the 305 series. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the receiving PCB accommodates the specified 3.96 mm pitch and nominal 1.57 mm board thickness for proper mechanical fit. Cross-reference the datasheet for environmental operating temperature ranges to validate suitability for the target application environment.

Edgeboard Connectors Selection Notes

Select this component when a 72-position dual-row interface is required for vertical PCB mounting. The 3.96 mm pitch is suitable for standard density applications. Consider the 5 A current rating and gold plating for durability. Compare against other 305 series variants if different row counts or termination styles are needed. Ensure the mating card edge thickness aligns with the connector's acceptance range.
