305-072-520-201

Edgeboard Connectors Overview

The EDAC Inc. 305-072-520-201 is a standard card edge connector receptacle featuring 72 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for PCB mount installation with straight orientation. The contacts are constructed from copper alloy with gold plating, rated for 5 A current. The housing is made of thermoplastic polyester, colored green, and supports board thicknesses of 1.57 mm. Operating temperatures range from -40°C to +105°C, with an insulation resistance of 5 GOhms.

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffix codes to confirm specific packaging and compliance attributes. Confirm RoHS status and moisture sensitivity levels prior to ordering. Ensure compatibility with existing board layout dimensions and mating card specifications. Check manufacturer lead times as production cycles may vary. Validate that the selected variant meets all environmental operating requirements for the intended application.

Edgeboard Connectors Selection Notes

Select this component when a 72-position dual-row interface is required for rigid board connections. Consider the 3.96 mm pitch constraint against available mating card edge widths. Evaluate the 5 A current rating against total circuit load requirements. Verify that the straight mounting style aligns with chassis depth limitations. Assess the -40°C to +105°C temperature range against operational extremes.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations for diverse connectivity needs. Components in this family share common mechanical interfaces and material standards. The 305 series is widely used in industrial and commercial electronics requiring robust edgeboard connections.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-072-521-201 and 305-072-520-204. Verify that alternative suffixes do not alter electrical ratings or mechanical dimensions. Cross-reference pinout configurations to ensure functional equivalence. Confirm that housing materials and flange characteristics match the original design requirements.
