Edgeboard Connectors Procurement Notes

Verify the specific suffix code to confirm plating thickness and housing color variations within the 305 series. Ensure compatibility with the target PCB thickness of 0.062 inches before integration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor channels. Cross-reference the full part number against the latest EDAC ordering guide to validate availability and lead times.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is required for a 48-position interface. The 3.96 mm pitch accommodates standard board layouts while maintaining a compact form factor. Verify that the operating temperature range of -40°C to +105°C meets environmental requirements. Consider the 5 A current rating for power distribution needs alongside signal integrity in high-density applications.

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 styles. The 305-048 variant specifically addresses mid-range density requirements. The model number encodes key attributes including position count, row configuration, and termination type. It serves as a reliable solution for connecting double-sided edge cards to system infrastructure.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 series parts with identical 48-position dual-edge specifications. Verify mechanical dimensions and electrical ratings match exactly. Alternative manufacturers may offer similar connectors but require thorough validation of pinout and tolerance compatibility.
