305-080-521-258

Edgeboard Connectors Overview

The EDAC Inc. 305-080-521-258 is a standard card edge connector from the 305 series, designed for dual-edge female applications. It features 80 positions with a 3.96 mm (0.156 inch) pitch and accepts board thicknesses between 1.37 mm and 1.78 mm. The connector utilizes copper alloy contacts with gold plating to ensure reliable signal transmission. Rated for 5 A continuous current and 1800 VACrms insulation voltage, it supports panel mounting via threaded inserts. The housing is constructed from green thermoplastic polyester, providing durability across an operating temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration with semi-beryllium copper contacts for secure mating
• Accepts between-contact and in-contact polarizing keys for alignment
• Panel mount design with threaded flange features for stable installation

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation boards

Edgeboard Connectors Procurement Notes

Verify that the specific order matches the manufacturer part number 305-080-521-258 to ensure correct contact count and pitch specifications. Confirm compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm before integration. Check for RoHS3 compliance requirements if environmental regulations apply to the final assembly. Ensure that the mounting hole pattern aligns with the threaded insert specifications provided in the official datasheet.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required for panel-mounted applications. The 80-position capacity suits designs needing substantial I/O density within a compact footprint. Consider the 5A current rating and 1800VACrms dielectric strength for power and signal integrity needs. Verify that the threaded flange mounting style meets the mechanical constraints of the enclosure design compared to surface-mount alternatives.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which offers various mounting options and position counts for card edge applications. The series is characterized by its use of thermoplastic polyester insulators and gold-plated contacts. Similar models in the lineup may differ in position count or flange characteristics but share the fundamental 3.96 mm pitch architecture.

Edgeboard Connectors Replacement Considerations

Direct substitutes must maintain the 80-position dual-edge female configuration and 3.96 mm pitch. Verify that any alternative part supports the same 1.37–1.78 mm board thickness and panel mounting requirements. Cross-reference electrical ratings to ensure equivalent 5A current and 1800VACrms voltage handling capabilities.
