337-021-558-602

Edgeboard Connectors Overview

The EDAC Inc. 337-021-558-602 is a standard single-row card edge connector designed for through-hole mounting at a right angle. It features 21 positions with a 3.96 mm pitch and supports a maximum board thickness of 1.57 mm. The contacts are constructed from copper alloy with gold plating, rated for 3 A current. The housing utilizes thermoplastic polyester insulation, providing an insulation resistance of 5 GOhms. Operating temperatures range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Single-row female contact configuration with gold-plated copper alloy terminals
• Thermoplastic polyester insulator housing with flanges for secure mounting
• Right-angle through-hole installation with wire wrap termination style

Edgeboard Connectors Applications

• Standard card edge interconnection systems
• Industrial control circuit boards
• Communication equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact physical dimensions and terminal variations. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Confirm that the right-angle orientation aligns with the mechanical layout requirements of the assembly design.

Edgeboard Connectors Selection Notes

Select this component when a single-row, right-angle connection is required for cards up to 1.57 mm thick. The 3.96 mm pitch dictates the trace spacing on the mating board. Verify that the wire wrap termination method matches the available assembly infrastructure and that the 3 A current rating satisfies the electrical load requirements of the application.

Edgeboard Connectors Part Context

This part belongs to the EDAC 337 series of standard card edge connectors. The series offers various position counts and mounting styles. This specific model provides a robust solution for vertical board-to-board connections using a durable thermoplastic housing and reliable gold-plated contacts for consistent signal transmission.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 337 series variants for different position counts or termination types. No direct functional equivalents from other manufacturers are confirmed in public databases; verify pinout and mechanical footprint compatibility if considering alternative sources.
