Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm flange characteristics and termination style. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS compliance status through manufacturer datasheets. Validate supply chain availability directly with authorized distributors as inventory levels fluctuate. Cross-reference part numbers to avoid substitution errors in critical assemblies.

Edgeboard Connectors Selection Notes

Select this connector when a 36-position dual-row interface is required for vertical panel mounting. The 3.96 mm pitch suits applications needing robust mechanical retention for standard thickness boards. Consider the 5 A current rating for power distribution needs within the specified temperature range. Evaluate the gold plating requirement for corrosion resistance in demanding environments. Compare against alternative series if different flange or termination options are necessary.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in position counts and mounting styles. The 305-036 variant specifically addresses high-density connection requirements in a compact form factor. It complements other series like 315 and 345 which offer variations in pitch and row spacing for diverse application needs.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC 305-036-521-202 and 305-036-521-201. Verify that replacement parts match the original flange features and termination type. Ensure identical electrical ratings and physical dimensions for seamless integration.
