Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact pin count, plating thickness, and termination style. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Cross-reference the RoHS compliance status with the latest datasheet revision to meet regulatory requirements for your specific market. Confirm that the selected variant matches the required current rating and operating temperature range for the intended application environment.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 12 positions is required for a 0.062-inch thick board. The 3.96 mm pitch suits applications where space efficiency is balanced with high-density connectivity needs. Consider the 5 A current rating and 5 GOhm insulation resistance for general-purpose electronic circuits. Evaluate the vertical or straight mounting options available within the 305 series to match the mechanical constraints of the enclosure design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and mounting styles to support diverse PCB integration needs. Components in this family typically feature thermoplastic polyester insulators and gold-plated contacts for long-term reliability. The 305-012-500-503 specifically addresses applications requiring a compact dual-row solution with standardized dimensions.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series parts with matching 12-position dual-row configurations and 3.96 mm pitch. Verify that alternative components maintain the same 1.57 mm board thickness acceptance and 5 A current rating. Ensure the replacement part shares identical mounting style and termination type to fit existing PCB footprints without redesign.
