Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, row configuration, and plating specifications. Ensure compatibility with the target PCB thickness and mounting hole dimensions before procurement. Cross-reference the part number with authorized distributors to confirm current availability and lead times. Request updated documentation to validate compliance with recent regulatory standards such as RoHS requirements.

Selection Notes

Select this connector when a dual-row interface with a 3.96 mm pitch is required for vertical panel mounting. Confirm that the application environment stays within the specified -40°C to +105°C operating range. Verify that the target PCB thickness matches the 1.57 mm design specification for proper contact engagement. Ensure sufficient clearance for the vertical profile and check that the 5 A current rating meets the circuit demands.

Part Context

This component belongs to the EDAC 306 series of standard card edge connectors, which are engineered for high-reliability applications requiring durable connections. The series typically features thermoplastic insulators and gold-plated contacts to withstand harsh environmental conditions. These connectors are widely used in sectors demanding stable signal transmission and mechanical resilience over extended operational lifespans.

Replacement Considerations

Direct substitutes must match the 54-position, dual-row, 3.96 mm pitch specification. Verify that alternative parts support the same 1.57 mm PCB thickness and vertical panel mount orientation. Ensure equivalent current ratings and temperature ranges are maintained for safe operation.
