Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required insulation color and termination type. Confirm that the package quantity matches project requirements, as factory packaging may vary. Cross-reference the RoHS status and material declarations with latest regulatory updates before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this connector when a dual-edge interface with a 3.96 mm pitch is required for high-density applications. Ensure the host PCB thickness falls within the specified 1.37 mm to 1.78 mm range for proper engagement. Consider the straddle mount style if panel mounting is preferred over vertical header configurations. Verify thermal ratings align with operational environments up to 105°C.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options designed for robust electronic interconnections. The 305 series is characterized by its durable construction and standardized dimensions, facilitating widespread use in modular electronic systems requiring reliable signal transmission.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series variants with matching 74-position dual-edge specifications. Verify identical pitch, row count, and mounting style when selecting alternative part numbers from the same manufacturer or cross-brand equivalents.
