Edgeboard Connectors Procurement Notes

Verify the specific suffix '203' against official EDAC documentation to confirm flange characteristics and pin count alignment. Ensure compatibility with target PCB stack-up dimensions and mating card thickness specifications before procurement. Cross-reference the manufacturer's latest datasheet to validate current production status and compliance certifications.

Edgeboard Connectors Selection Notes

Select this component when a 72-position dual-row interface is required with a 3.96 mm pitch. Confirm that the 5 A current rating meets circuit demands and that the 1.57 mm board thickness specification aligns with the design. Evaluate the straight PCB mount orientation and solder termination method against assembly constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and flange options while maintaining consistent electrical ratings and mechanical interfaces. The 305 series is designed for general-purpose applications requiring reliable through-hole mounting and durable performance across specified temperature ranges.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but different flange styles or plating options. Verify mechanical fit and electrical continuity before swapping. Consult the EDAC 305 Series Ordering Guide for approved alternative part numbers.
