Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm plating thickness and material specifications. Ensure compatibility with the target PCB edge thickness of 1.57 mm. Confirm that the vertical panel mount style aligns with the mechanical enclosure requirements. Cross-reference the 40-position count and 3.96 mm pitch with the design schematic to prevent mating errors.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge interface is required for high-density signal routing. The 3.96 mm pitch accommodates standard board layouts while maintaining adequate spacing. The 5 A current rating suits moderate power distribution needs. Verify that the operating temperature range meets the environmental conditions of the intended application site before finalizing the design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles to support diverse electronic assembly needs. The 305 series is characterized by its robust thermoplastic construction and reliable solder pin termination, making it suitable for general-purpose industrial and commercial applications requiring durable board-to-board or board-to-backplane connections.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC substitution guide for verified alternative part numbers within the 305 series. Ensure any substitute matches the 40-position count, 3.96 mm pitch, and dual-edge configuration. Verify that the replacement maintains the same vertical panel mount style and solder pin termination type to preserve mechanical fit.
