305-078-555-202

Edgeboard Connectors Overview

The EDAC Inc. 305-078-555-202 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 78 positions arranged in two rows with a 3.96 mm (0.156 inch) contact spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Contacts are made of copper alloy and gold-plated, rated for 5 A current. The insulator body is green thermoplastic polyester, operating between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified PCBs
• Panel mount installation with vertical orientation
• Gold-plated copper alloy contacts for reliable signal transmission
• Thermoplastic polyester insulator body for durability

Edgeboard Connectors Applications

• Rack and panel interconnect systems
• Industrial control panels
• Computing and storage hardware backplanes
• Aerospace electronic assemblies

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm flange characteristics and thread type, as variations exist within the 305 series. Confirm that the target PCB thickness aligns with the 1.57 mm nominal requirement. Ensure compatibility with the required 3.96 mm pitch and dual-row layout. Check RoHS compliance status if restricted substances are a constraint for the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a high-density 78-position connection is required for panel-mounted architectures. The vertical design facilitates direct board insertion into chassis slots. Consider the 5 A current rating per contact for power distribution needs. The robust metal flange provides mechanical stability compared to lower-profile alternatives.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in rack and panel applications. The series offers various position counts and mounting styles. The 305-078 variant specifically addresses high-pin-count requirements while maintaining the standard 3.96 mm pitch established by the family.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series parts with matching 78 positions and 3.96 mm pitch, such as 305-078-555-568, provided the flange threading matches the application. Cross-brand replacements require verification of identical pin count, pitch, and PCB thickness tolerance.
