Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and housing color variations. Ensure compatibility with the target PCB thickness of 1.57 mm during mechanical integration. Confirm that the 5 A current rating aligns with the application's electrical load requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this model when a 34-position interface with a 3.96 mm pitch is required. Consider the vertical panel mount style for applications necessitating direct board insertion. Evaluate the need for polarizing key acceptance if precise orientation is critical. Compare against similar series components if different row spacings or contact counts are needed.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and mounting styles for diverse electronic applications. The 305-034-500-203 specifically addresses needs for mid-range position counts with durable thermoplastic construction. It complements other series like 315 and 355 which may offer different spacing or profile characteristics.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 34 positions and 3.96 mm pitch. Verify mechanical dimensions and pinout configurations before replacing.
