Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct pin count, plating, and mounting style. Confirm RoHS compliance status through official documentation before procurement. Check regional availability restrictions as distribution may vary by location. Ensure compatibility with the target PCB thickness of 1.57 mm during integration planning.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connection is required for 1.57 mm thick PCBs. The 3.96 mm pitch suits applications needing robust mechanical retention. Verify that the 5 A current rating meets the circuit requirements. Consider the panel mount style if chassis integration is necessary rather than direct PCB soldering.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting configurations. The 305-050 variant specifically provides fifty contact points. The product line utilizes thermoplastic insulators and copper alloy contacts. This series supports both single and dual-row arrangements for diverse electronic assembly needs.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include 305-040-556-268 and 305-054-556-268. These parts share identical electrical and mechanical specifications but differ in position count. Verify exact pin alignment and housing dimensions before substitution.
