305-082-521-201

Edgeboard Connectors Overview

The EDAC 305-082-521-201 is a standard card edge connector receptacle featuring 82 positions arranged in two rows. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm row spacing. Designed for .062 inch (1.57 mm) nominal thickness printed circuit boards, the unit employs gold-plated copper alloy contacts and a thermoplastic polyester insulator. The component supports a current rating of 5 A per contact and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female configuration accepting non-specified dual-edge cards
• Low profile insulator body construction
• Gold-plated copper alloy contact surfaces
• Solder pin termination for PCB mounting

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Automotive electronic module connections
• Test and measurement instrumentation interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific suffix matches the required board thickness and termination style. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply chain sources provide authentic components with traceable manufacturing records to guarantee long-term reliability in critical applications.

Edgeboard Connectors Selection Notes

Select this connector when a high-density interface with 82 positions is required for thick PCBs. The 3.96 mm pitch accommodates robust signal routing needs. Verify that the mating card edge geometry aligns with the dual-edge specification. Consider thermal management requirements given the 105°C maximum operating limit.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting configurations. The 305 series is characterized by its durable thermoplastic polyester housing and reliable solder pin termination methods suitable for panel or PCB mounting applications.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 82-position counts and identical 3.96 mm pitch specifications. Cross-manufacturer replacements require verification of mechanical dimensions, electrical ratings, and mating interface compatibility.
