305-020-555-568

Edgeboard Connectors Overview

The EDAC Inc. 305-020-555-568 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 20 positions with a 3.96 mm (0.156 inch) pitch and accepts PCBs with a nominal thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-row female configuration for non-specified dual-edge cards
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Thermoplastic polyester insulator provides stable mechanical support
• Panel mount style with vertical orientation for secure installation

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing dual-edge module connections
• Test and measurement devices needing high-reliability interconnects
• Embedded computing platforms with standardized card form factors

Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC distributors or verified supply chain channels. Confirm RoHS compliance status and specific lot traceability requirements prior to purchase. Ensure storage conditions maintain material integrity, as humidity sensitivity may affect solderability. Cross-reference ordering suffixes to confirm exact pin count and termination type match system specifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this model when a dual-row, 20-position interface is required for 1.57 mm thick boards. The 3.96 mm pitch accommodates standard dual-edge card layouts. Verify that the panel mounting style aligns with chassis design constraints. Consider the 5 A current rating and operating temperature range against system thermal profiles. Ensure compatibility with existing manufacturing processes for solder pin termination methods.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, a family of standard card edge connectors. The series offers various position counts and mounting options, all sharing consistent electrical characteristics and dimensional standards. The 305-020-555-568 specifically addresses applications requiring a compact, dual-row interface with high durability and precise alignment capabilities for industrial-grade environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers with identical 20-position, 3.96 mm pitch, and dual-row configurations, such as 305-020-556-568 if termination differences are acceptable. Verify mechanical dimensions and contact plating specifications to ensure functional equivalence without redesigning the host PCB layout.
