305-072-521-204

Edgeboard Connectors Overview

The EDAC Inc. 305-072-521-204 is a standard card edge connector receptacle from the 305 Series, designed for PCB mounting. It features 72 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Rated for 5 A continuous current, it employs a solder termination method and includes flanges for secure installation.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for enhanced board alignment
• Features a low-profile insulator body constructed from thermoplastic polyester
• Provides reliable electrical connection through gold-plated copper alloy semi-波纹管 contacts

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment utilizing standard card edge interfaces
• Automotive electronics modules needing robust PCB connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and housing color variations. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm RoHS compliance status as per the latest manufacturer documentation. Cross-reference the full part number against distributor catalogs to avoid substitution errors.

Edgeboard Connectors Selection Notes

Select this component when a 72-position dual-row interface is required for vertical PCB mounting. Consider the 3.96 mm pitch constraint for trace routing density. Evaluate the 5 A current rating against system power requirements. Verify that the straight mounting angle aligns with the mechanical enclosure design constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which offers various mounting options and row configurations. The series is characterized by its standardized 3.96 mm pitch and durable construction suitable for repeated insertion cycles. It serves as a critical interconnect solution within the broader EDAC card edge connector portfolio.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include models with different position counts such as 305-086-521-204 or 305-058-521-204, provided the pitch and mounting style remain consistent.
