355-054-555-503

Edgeboard Connectors Overview

The EDAC Inc. 355-054-555-503 is a dual-edge female card edge connector featuring 54 positions with a 0.156-inch (3.96mm) pitch. It utilizes gold-plated copper alloy contacts and a black thermoplastic polyester insulator. Designed for board edge straddle mounting, it accepts printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches. The component supports solder termination and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to confirm compatibility with target PCB thickness and mounting requirements. Ensure that the ordering suffix matches the desired contact spacing and insulation material specifications. Cross-reference the manufacturer's latest datasheet to validate environmental ratings and RoHS compliance status before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this connector when a dual-edge interface with a 0.156-inch pitch is required for robust mechanical stability. The straddle mount style offers superior retention compared to standard panel mounts. Consider the operating temperature range and contact plating thickness to ensure suitability for the intended electrical environment and durability requirements.

Edgeboard Connectors Part Context

This component belongs to the EDAC 355 series of standard card edge connectors. The series is characterized by high-density configurations and durable construction materials. The 355-054 variant specifically addresses applications requiring 54 connection points in a compact dual-row format.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 355 Series Ordering Guide for direct substitutes with differing position counts or mounting styles. Verify that alternative parts maintain identical pitch dimensions and board thickness tolerances to ensure mechanical fit.
