305-054-521-207

Edgeboard Connectors Overview

The EDAC Inc. 305-054-521-207 is a standard card edge connector from the 305 series, designed for panel mounting with vertical orientation. It features 54 positions arranged in two rows with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches), ranging from 1.37 mm to 1.78 mm. Contacts are made of copper alloy with gold plating and utilize a solder pin termination type. The housing is constructed from green thermoplastic polyester.

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required position count and pitch specifications before procurement. Confirm compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Ensure the solder pin termination method aligns with the assembly process capabilities. Check for RoHS compliance status if environmental regulations apply to the final product deployment.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-row connection is necessary for panel-mounted applications. The 3.96 mm pitch offers a balance between signal density and mechanical robustness. Consider the gold plating for environments requiring corrosion resistance. Verify that the vertical panel mount style fits within the enclosure constraints and allows for proper board insertion clearance.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in accepting various board thicknesses and its durable construction suitable for industrial environments. The 305 series typically utilizes thermoplastic materials for the insulator and copper alloys for contacts, ensuring consistent performance across different positioning configurations.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but different termination or housing variations. Cross-referencing with other manufacturers requires matching the 3.96 mm pitch, 54-position layout, and 1.57 mm board thickness acceptance. Verify mechanical footprint and electrical ratings before substitution.
