305-072-555-268

Edgeboard Connectors Overview

The EDAC Inc. 305-072-555-268 is a standard card edge connector from the 305 series, designed for PCB mounting in a straight orientation. It features a dual-row configuration with 72 positions and a contact spacing of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts with a half-bead type to ensure reliable signal transmission. It accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches) and provides a continuous current rating of 5 A. The insulator body is constructed from thermoplastic polyester, offering an insulation resistance of 5 Gohms.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact physical dimensions, flange characteristics, and termination style. Ensure compatibility with the target PCB thickness of 1.57 mm and confirm that the 5 A current rating meets the application's electrical requirements. Cross-reference the RoHS status and material composition with project specifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a 72-position dual-row interface is required for a 1.57 mm thick board. The 3.96 mm pitch allows for standard trace routing while maintaining a compact footprint. Consider the straight mounting angle and thermoplastic construction for environments where moderate thermal stability and chemical resistance are necessary. Verify that the gold plating thickness aligns with the expected mating cycle durability.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various mounting options and row spacings for card edge applications. The series is characterized by its use of thermoplastic polyester insulators and gold-plated contacts. Similar parts in the lineup vary primarily by position count and specific mounting configurations, providing flexibility for different density requirements within the same structural family.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include models such as 305-072-555-202 or 305-072-555-512, provided they match the required flange and termination specifications. Verify that any alternative part number maintains the identical 72-position count, 3.96 mm pitch, and 1.57 mm board thickness acceptance to ensure mechanical interchangeability.
