305-028-555-503

Edgeboard Connectors Overview

The EDAC Inc. 305-028-555-503 is a dual-row female card edge connector designed for vertical panel mounting. It features 28 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 copper alloy contacts featuring gold plating, the unit utilizes a green thermoplastic polyester insulator body. It supports a solder lug termination method and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration with low-profile insulator body
• Gold-plated copper alloy contacts for reliable signal transmission
• Vertical panel mount design with floating eyelets

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Test and measurement equipment interfaces
• Telecommunications hardware modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official catalog to ensure correct pin count and termination style. Confirm that the target application requires the standard 0.156-inch pitch specification. Check current availability status as distribution may vary by region. Ensure compliance with RoHS3 regulations if required by project specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector is needed for 0.062-inch thick PCBs. The 28-position count suits moderate density applications. Consider the vertical mounting orientation and solder lug termination requirements during mechanical design. Verify that the operating environment stays within the specified thermal limits.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides various mounting options and position counts. The series is characterized by its 3.96 mm pitch and durable construction suitable for standard card edge applications. It serves as a specialized interconnect solution within the broader EDAC portfolio of edgeboard connectors.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 28-position configurations and identical pitch specifications. Cross-referencing with similar manufacturers requires verifying exact dimensional tolerances and contact material properties to ensure functional compatibility.
