305-054-555-578

Edgeboard Connectors Overview

The EDAC Inc. 305-054-555-578 is a standard card edge connector from the 305 series, designed for panel mounting applications. It features 54 positions arranged in two rows with a contact pitch of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator body. It supports a continuous current rating of 5 A and withstands 1800 VACrms dielectric voltage. The unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches) and employs solder pin termination.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body with straddle mount installation style
• Includes integrated card guide functionality to assist in board insertion

Edgeboard Connectors Applications

• Panel-mounted electronic systems requiring dual-edge card connections
• Industrial control modules utilizing polarized PCB designs
• High-density interconnect applications needing 5 A current capacity

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to ensure compatibility with required polarizing key configurations and termination styles. Confirm that the thermal plastic polyester housing meets environmental requirements for the intended operating temperature range of -40°C to +105°C. Cross-reference the 54-position count and 3.96 mm pitch with the target PCB layout specifications before procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 54-position connection is required with a 3.96 mm pitch. Ensure the application supports panel mounting and can accommodate the 1.57 mm board thickness constraint. Verify that the 5 A current rating and 1800 VACrms insulation resistance align with system electrical demands. Consider the availability of compatible polarizing keys if mechanical locking is necessary.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are characterized by their robust construction and versatile mounting options. The series offers various position counts and row configurations to suit different interface densities. The 305-054-555-578 specifically addresses high-pin-count needs within the 3.96 mm pitch family, providing a reliable solution for vertical or straddle-mounted interfaces.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but differing row configurations or termination styles. Verify mechanical fit and electrical ratings before swapping. No alternative manufacturer part numbers are confirmed as direct replacements without custom engineering.
