Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm termination type and plating details. Ensure the target application supports the required 1.57 mm PCB thickness and 3.96 mm pitch. Confirm compliance with RoHS directives if environmental regulations apply. Cross-reference the part number with official EDAC documentation to validate availability and lead times prior to procurement.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count dual-row interface is necessary for vertical panel mounting. The 3.96 mm pitch accommodates standard board layouts while maintaining robust electrical performance. Consider the 5 A current rating for power distribution requirements. Verify that the thermoplastic housing meets the thermal and mechanical demands of the specific enclosure environment.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and mounting configurations. The series is characterized by its standardized 3.96 mm spacing and compatibility with 0.062 inch thick cards. The 305-082-556-501 variant specifically addresses applications requiring 82 positions in a dual-row arrangement, providing a compact solution for dense interconnect needs.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row spacing but different position counts, such as the 305-070-556-568 or 305-054-556-278. Verify mechanical fit and pin count compatibility before substitution. Alternative manufacturers may offer similar connectors, but dimensional tolerances and termination styles must be strictly matched.
