305-058-521-278

Edgeboard Connectors Overview

The EDAC Inc. 305-058-521-278 is a standard card edge connector from the 305 series, designed for panel-mounted applications. It features a dual female configuration with 58 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm. Constructed with copper alloy contacts finished in gold plating, it ensures reliable signal transmission. The housing is made of thermoplastic material, providing durability and insulation resistance of 5 GOhms. Rated for 5 A current at operating temperatures ranging from -40°C to +105°C, this component employs solder lug termination for secure board attachment.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, termination type, and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm and verify that the panel mounting requirements align with the connector's physical dimensions. Cross-reference the RoHS compliance status and lead time availability through authorized distributors prior to final procurement decisions.

Edgeboard Connectors Selection Notes

Select this connector when a high-density dual-row interface is required for panel-mounted assemblies. The 3.96 mm pitch allows for substantial trace routing while maintaining a compact footprint. Consider the 5 A current rating and wide temperature range for robust environmental performance. Verify that the solder lug termination method matches the assembly process capabilities and that the gold plating meets the necessary cycle life requirements for mating cycles.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are widely used in various electronic industries. The series offers multiple position counts and termination options to suit different design needs. As a panel-mount solution, it provides stable mechanical support for inserted cards, ensuring consistent electrical contact under vibration and thermal cycling conditions typical in industrial and commercial applications.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 series ordering guide for alternative part numbers with varying position counts or termination styles. Direct substitutes must maintain the same 3.96 mm pitch, dual-row configuration, and panel mount form factor to ensure mechanical and electrical compatibility within existing designs.
