305-084-500-278

Edgeboard Connectors Overview

The EDAC Inc. 305-084-500-278 is a standard card edge connector from the 305 Series, designed for dual-row applications with 84 positions. It features a 3.96 mm (0.156 inch) pitch and accepts PCBs with a thickness of 1.57 mm. The contacts are gold-plated copper alloy, providing a continuous current rating of 5 A. This receptacle utilizes a solder termination type and is housed in green thermoplastic polyester. It supports between-contact and in-contact polarizing keys for secure alignment.

Edgeboard Connectors Feature Summary

• Dual-row configuration with 84 positions for high-density interconnects
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Compatible with between-contact and in-contact polarizing keys
• Green thermoplastic polyester housing provides insulation and durability

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized connector pitches
• Test and measurement devices needing secure board mounting
• Automotive electronics modules with specific thermal requirements

Edgeboard Connectors Procurement Notes

Verify the exact suffix codes against the manufacturer's official datasheet to confirm termination style and housing material variations. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Cross-reference the 84-position count and 3.96 mm pitch with system design specifications to prevent mechanical mismatch during assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge solution with a 3.96 mm pitch is required. The 5 A current rating suits moderate power applications. Consider the solder termination method for permanent PCB attachment. Evaluate the need for polarizing key compatibility if precise board orientation is critical for the specific assembly process.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various configurations for card edge connectors. The series includes headers and receptacles with different position counts and mounting styles. The 305-084-500-278 specifically addresses the need for an 84-position dual-row interface with gold contact plating and a standard industrial pitch.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but different termination or mounting options. Verify that any replacement maintains the 3.96 mm pitch and 84-position layout to ensure mechanical fit.
