345-102-558-258

Edgeboard Connectors Overview

The EDAC Inc. model 345-102-558-258 is a standard card edge connector from the 345 series, designed for dual-edge board applications. It features 102 positions with a 0.100 inch (2.54 mm) pitch and supports non-specified dual-edge cards. The connector utilizes copper alloy contacts with gold plating to ensure reliable signal transmission. Rated for 3 A current, it operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, providing durability and insulation. This through-hole device is engineered for secure panel or board mounting in electronic assemblies requiring high-density interconnects.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for secure insertion of double-sided circuit boards
• Gold-plated copper alloy contacts ensure low resistance and corrosion resistance
• Thermoplastic polyester housing provides thermal stability and electrical insulation
• Through-hole termination method ensures robust mechanical attachment to the PCB

Edgeboard Connectors Applications

• High-density backplane interconnections in industrial control systems
• Signal routing in telecommunications equipment chassis
• Interface connections for specialized computing hardware modules
• Data acquisition system board-to-board linking

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to confirm exact pin count, plating thickness, and flange specifications. Ensure compatibility with the target card edge thickness range of 0.054 to 0.070 inches. Confirm that the required lead time aligns with project schedules, as availability may vary by region. Cross-reference the RoHS status if environmental compliance is mandatory for the end application.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connector with a 2.54 mm pitch is required for high-pin-count applications. The 102-position capacity suits designs needing extensive I/O lines without increasing footprint. Consider the right-angle orientation and through-hole mounting style for fixed structural integration. Evaluate the 3 A rating against the total current load of the connected circuitry to prevent overheating during continuous operation.

Edgeboard Connectors Part Context

This part belongs to the EDAC 345 series of standard card edge connectors, which are widely used in modular electronic systems. The series offers various position counts and termination styles to accommodate different design constraints. The 345-102 variant specifically addresses needs for dense dual-edge connections, balancing high channel counts with standard spacing dimensions common in legacy and modern industrial electronics.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 102-position count, 2.54 mm pitch, and dual-edge female configuration. Verify that alternative parts support the same 0.054 to 0.070 inch card thickness and offer comparable gold plating and current ratings. Ensure mechanical fitment, including flange type and mounting hole alignment, is identical to maintain assembly integrity.
