305-014-521-258

Edgeboard Connectors Overview

The EDAC Inc. 305-014-521-258 is a standard card edge connector from the 305 series, designed for vertical panel mounting applications. It features a dual female configuration with 14 positions arranged in two rows of seven contacts each. The connector utilizes a 0.156-inch (3.96 mm) pitch and accepts board thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm). Contacts are constructed from copper alloy with gold plating and employ a semi-beehave termination type. The unit supports solder pin end termination and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Vertical panel mount design with flush mount flange featuring top opening and threaded inserts
• Dual edge female contact configuration with gold-plated copper alloy terminals
• Semi-beehave contact type ensuring secure connection for specified card thicknesses

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Computing hardware module interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct flange and termination specifications. Confirm that the required board thickness falls within the 1.37 mm to 1.78 mm operational range. Check RoHS compliance status if environmental regulations apply to the assembly. Ensure the selected variant matches the required 14-position dual row layout for the target PCB design.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for dual-edge cards. The 3.96 mm pitch dictates the trace spacing on the mating PCB. Verify that the threaded insert flange feature aligns with the chassis mounting requirements. Consider the operating temperature range of -40°C to 105°C for environmental suitability. Ensure the gold plating meets conductivity and corrosion resistance needs for the application.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-014-521-258 specifically denotes a 14-position dual-row unit with a green thermoplastic polyester insulation body. It is distinct from single-row or different pitch variants within the same product family.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with identical electrical and mechanical parameters. Verify compatibility with existing chassis mounting holes due to the specific flange thread size.
