346-022-521-204

Edgeboard Connectors Overview

The EDAC Inc. 346-022-521-204 is a standard card edge connector receptacle featuring 22 positions arranged in a dual female configuration. It utilizes a 0.125-inch (3.175 mm) pitch and is designed for PCBs with a thickness of 1.57 mm. The component employs gold-plated copper alloy contacts to ensure reliable signal transmission. Rated for 3 A current, it supports through-hole mounting with wire wrap termination. The housing is constructed from thermoplastic polyester, providing structural integrity within the 346 series.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for secure card edge mating
• Gold-plated copper alloy contacts for corrosion resistance
• Thermoplastic polyester housing material for durability
• Wire wrap termination method for robust circuit board connection

Edgeboard Connectors Applications

• Industrial control systems requiring high-reliability interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation interfaces
• Automotive electronic module connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm exact pin count, plating thickness, and termination style. Ensure compatibility with the target PCB stack-up and card edge thickness specifications before finalizing procurement orders to prevent mechanical mismatch issues.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface is required with a 0.125-inch pitch. Confirm that the application environment stays within the specified operating temperature range. Validate that the wire wrap termination method aligns with the assembly process capabilities and that the 3 A current rating meets the circuit load requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 346 series of standard card edge connectors. The series offers various position counts and mounting styles. The 346-022-521-204 specifically addresses needs for moderate-density dual-row connections using through-hole technology, distinguishing it from surface-mount or single-row variants within the broader product family.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 346 series parts sharing the same 0.125-inch pitch and dual female configuration. Verify mechanical dimensions and electrical ratings match exactly. No direct substitute part numbers are confirmed in public documentation; consult EDAC engineering for approved equivalents.
