345-031-521-101

Edgeboard Connectors Overview

The EDAC Inc. 345-031-521-101 is a single-row female card edge connector designed for through-hole mounting. It features 31 positions with a 0.100-inch (2.54mm) pitch and accepts non-specified single-edge cards. The contacts are made of copper alloy with a gold plating thickness of 10.0µin (0.25µm). The insulator is green thermoplastic polyester, supporting board thicknesses from 0.054 to 0.070 inches. Operating temperature ranges from -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Single-edge female contact configuration for standard card insertion
• Through-hole termination method with cantilever spring contacts
• Gold-plated copper alloy contacts for reliable signal transmission
• Thermoplastic polyester insulator rated for high-temperature environments

Edgeboard Connectors Applications

• Industrial control system backplanes
• Medical device interconnects
• Agricultural technology equipment modules
• General-purpose circuit board expansion slots

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC datasheet to confirm flange type and termination style. Ensure compatibility with the target PCB stack-up regarding hole size and spacing. Confirm RoHS compliance status if required by project specifications. Check lead times as manufacturing schedules may vary. Validate that the single-edge design matches the mating card geometry before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a single-row interface is required for moderate pin counts. The 0.100-inch pitch provides ample spacing for standard manufacturing tolerances. Consider the through-hole mounting requirement for mechanical stability. Evaluate the operating temperature range against environmental conditions. Compare against multi-row alternatives if higher density is needed.

Edgeboard Connectors Part Context

This part belongs to the EDAC 345 series, which offers various configurations including single and double rows. The series supports different contact terminations and mounting options. Similar parts in the series include 345-032-541-588 for dual-row applications. The 345 series is designed for durability in harsh environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 345 series must match the 31-position count and single-edge specification. Verify that alternative part numbers maintain the same 0.100-inch pitch and through-hole termination. Cross-reference flange dimensions to ensure mechanical fit. Consult official cross-reference guides for verified equivalents.
