Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact termination style and contact plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm availability status through authorized distributors as supply constraints may apply. Cross-reference the polarizing key requirements with mating card edge designs to guarantee mechanical fit.

Edgeboard Connectors Selection Notes

Select this model when a 70-position dual-row interface is required for vertical panel applications. The 3.96 mm pitch accommodates standard card edge layouts while maintaining a 5 A current capacity. Verify that the mating connector supports the necessary polarizing key configurations. Consider the operating temperature range and insulation resistance values for environmental suitability in demanding industrial settings.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in handling various position counts and termination styles. The 305-070-500-204 variant specifically addresses high-pin-count applications requiring reliable vertical mounting solutions with standardized dimensional profiles.

Edgeboard Connectors Replacement Considerations

Consult official EDAC substitution guides for verified alternative part numbers within the 305 series. Ensure any replacement maintains identical pitch, position count, and mounting orientation. Verify that substitute components support the same polarizing key acceptance capabilities.
