305-064-556-503

Edgeboard Connectors Overview

The EDAC Inc. model 305-064-556-503 is a standard card edge connector designed for dual-row board-to-board interconnection. It features 64 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). It utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and supports a continuous current rating of 5 A. The unit employs a solder pin termination method for secure panel mounting.

Edgeboard Connectors Procurement Notes

Verify the specific manufacturer part number against official EDAC documentation to confirm compatibility with your design requirements. Ensure that the selected variant matches the required termination style and board thickness specifications. Cross-reference technical datasheets for insulation resistance and operating temperature ranges before finalizing procurement decisions. Confirm availability through authorized distribution channels.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 3.96 mm pitch is required. The 64-position count suits applications needing moderate density without excessive footprint. Verify that the 5 A current rating aligns with the power distribution needs of the target circuit. Consider the vertical panel mount style and solder pin termination for assembly constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series, which represents a line of standard card edge connectors. The series offers various position counts and termination options to accommodate different board densities. The 305 series is characterized by its use of thermoplastic insulators and gold-plated contacts, ensuring consistent performance across industrial and commercial electronic applications.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include models such as 305-064-556-502 or 305-064-520-503, provided they match the exact pin count and termination type. Verify that any alternative part maintains the same 3.96 mm pitch and 0.062 inch board thickness acceptance to ensure mechanical fit.
