Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm exact termination type and plating thickness. Confirm RoHS compliance status through official documentation prior to procurement. Ensure that the selected variant matches the required PCB thickness specification of 1.57 mm for proper mechanical fit. Cross-reference the part number with authorized distributors to validate availability and authenticity.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required for panel-mounted assemblies. The 28-position count suits moderate density applications. Verify compatibility with the target printed circuit board edge guide dimensions. Consider the thermal operating range limits if the environment exceeds standard industrial temperatures. Ensure the solder pin termination method aligns with the assembly process capabilities.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which provides a range of standard card edge solutions.
