305-064-521-204

Edgeboard Connectors Overview

The EDAC Inc. 305-064-521-204 is a standard card edge connector from the 305 series, designed for dual female edgeboard applications. It features 64 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with gold-plated contacts on a copper alloy base, it utilizes a low-profile thermoplastic insulator body. The unit employs solder pin termination and is rated for 5 A current.

Edgeboard Connectors Feature Summary

• Dual female configuration supporting two-row board insertion
• Gold-plated contacts ensure reliable signal transmission
• Low-profile insulator body design for compact integration
• Solder pin termination for secure panel mounting

Edgeboard Connectors Applications

• Industrial control systems requiring robust edge connections
• Telecommunications equipment backplanes
• Computing hardware motherboards and expansion cards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating and termination style match project requirements. Confirm that the PCB thickness tolerance aligns with the 1.57 mm nominal specification. Ensure the selected variant corresponds to the dual female configuration. Cross-reference the manufacturer part number against official distributor catalogs to avoid counterfeit components. Check for any recent obsolescence notices or lifecycle changes before finalizing procurement plans.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 64 positions is required. The 3.96 mm pitch suits applications needing wider spacing than standard 2.54 mm headers. Verify compatibility with the target PCB's mechanical constraints regarding the 1.57 mm thickness limit. Consider the 5 A current rating for power distribution needs within the system architecture.

Edgeboard Connectors Part Context

This model belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations for edgeboard applications. The 305 line is characterized by its durable construction and consistent electrical performance across different form factors.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with identical 64-position dual female specifications. Verify mechanical dimensions and electrical ratings before swapping with non-EDAC brands.
