346-090-522-207

Edgeboard Connectors Overview

The EDAC 346-090-522-207 is a standard card edge connector receptacle featuring 90 positions with a 3.18 mm (0.125 inch) pitch. It utilizes gold-plated contacts and is designed for dual-edge card insertion. The unit supports a current rating of 3 A and operates within a temperature range up to +105 °C. Constructed with a green thermoplastic polyester housing, it employs PC pin termination for vertical through-hole mounting on PCBs with a thickness of 1.57 mm.

Edgeboard Connectors Feature Summary

• Dual-edge card edge interface design
• Gold-plated contact surfaces for conductivity
• Vertical through-hole PC pin termination

Edgeboard Connectors Applications

• High-density electronic module interconnects
• Industrial control system backplanes
• Telecommunications equipment interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB stack-up and verify that the 3.18 mm pitch aligns with the mating card edge dimensions. Confirm RoHS compliance status through the manufacturer's latest certification records before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-count, single-row connection is required for dual-edge cards. The 3.18 mm pitch offers robust spacing compared to finer pitches. Consider the vertical orientation and PC pin style for board-level stability. Evaluate the 3 A current rating against the application's power distribution requirements to ensure adequate thermal performance during operation.

Edgeboard Connectors Part Context

This part belongs to the EDAC 346 series of standard card edge connectors. The series provides various position counts and termination styles. The 346 series is characterized by its use of thermoplastic polyester housings and standardized pitch dimensions. It serves as a reliable solution for connecting daughter boards to motherboards in compact electronic assemblies requiring durable mechanical retention.

Edgeboard Connectors Replacement Considerations

Consult official EDAC cross-reference guides for verified substitute part numbers. Generic equivalents may not match the precise 3.18 mm pitch or dual-edge geometry. Verify that any replacement maintains the same vertical mounting angle and PC pin termination type to ensure physical fit and electrical continuity.
