Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required termination type and contact finish specifications. Confirm panel mounting requirements align with the vertical installation angle. Ensure the target PCB thickness corresponds to the 1.57 mm acceptance criteria. Check regional availability status as distribution may vary by location. Validate RoHS compliance documentation if environmental regulations apply to the assembly.

Edgeboard Connectors Selection Notes

Select this component when dual-edge connectivity is required for high-density signal routing. The 3.96 mm pitch suits applications needing robust mechanical stability. Verify that the 5 A current rating meets the electrical load requirements. Consider the operating temperature range for environmental suitability. Ensure the panel mount style fits the enclosure design constraints compared to PCB mount alternatives.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options. Similar models include 305-040-500-502 and 305-038-520-502, which share the same pitch but differ in position count. The 305 series is characterized by its low-profile thermoplastic housing and reliable gold-plated contact systems for industrial use.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the 305 series include 305-084-500-278, which shares the 84-position count and 3.96 mm pitch but differs in termination style. Cross-series replacements require verification of pitch and row spacing compatibility. Ensure mechanical dimensions and mounting styles match the existing design before substitution.
