305-072-521-207

Edgeboard Connectors Overview

The EDAC Inc. 305-072-521-207 is a standard card edge connector receptacle featuring 72 positions arranged in two rows. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for PCB mount installation with a straight orientation. The contacts are gold-plated copper alloy, supporting a current rating of 5 A. The housing is constructed from green thermoplastic polyester, providing an insulation resistance of 5 GOhms. It operates within a temperature range of -40°C to +105°C and accepts board thicknesses up to 1.57 mm.

Edgeboard Connectors Feature Summary

• Dual-row female configuration for non-specified dual-edge cards
• Gold-plated cantilever spring contacts for reliable signal transmission
• Thermoplastic polyester housing with high insulation resistance
• Straight PCB mount design with solder termination

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation boards
• Automotive electronic module connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required flange features or contact plating variations. Confirm that the component meets RoHS3 compliance standards for your target market regulations. Cross-reference the pin count and row configuration with your PCB layout specifications before finalizing procurement orders to prevent integration errors.

Edgeboard Connectors Selection Notes

Select this model when a 72-position dual-row interface is required for dual-edge card applications. Ensure the mating card thickness falls within the specified mechanical limits. Consider the straight mounting style for space-constrained vertical installations. Verify that the 5 A current rating per contact aligns with the system's power distribution requirements.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations tailored for diverse electronic assembly needs. The 305 series is characterized by its durable construction and consistent electrical performance across industrial environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers within the same 305 series family sharing identical 72-position, dual-row, and 3.96mm pitch specifications. Verify mechanical dimensions and contact type equivalence before substitution.
