305-064-521-258

Edgeboard Connectors Overview

The EDAC Inc. 305-064-521-258 is a standard card edge connector designed for dual-edge board applications. It features 64 positions with a 0.156-inch (3.96 mm) pitch and supports board thicknesses between 0.054 and 0.070 inches. The connector utilizes gold-plated copper alloy contacts with a 10.0 µin finish and half-beam contact types. Rated for 5 A current, it employs panel mount and through-hole solder termination. Constructed with green thermoplastic polyester insulation, the unit operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Procurement Notes

Verify component authenticity by cross-referencing manufacturer serial codes against official EDAC documentation. Confirm RoHS compliance status matches current regulatory requirements before integration. Ensure storage conditions prevent moisture absorption despite the specified non-applicable MSL rating. Validate that procurement channels provide original manufacturer packaging to maintain connector integrity during transit.

Edgeboard Connectors Selection Notes

Select this model when designing systems requiring high-density dual-edge connections with robust mechanical retention. The 3.96 mm pitch accommodates standard PCB layouts while the 5 A rating supports moderate power loads. Verify that the target application environment remains within the specified -40°C to 105°C operational limits. Ensure the mating card thickness falls strictly within the 1.37 mm to 1.78 mm acceptance window for optimal contact engagement.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series, a line of standard card edge connectors engineered for general-purpose industrial and commercial electronics. The series offers various position counts and termination styles to support diverse board-to-board interface requirements. Designed for durability, these connectors utilize high-grade materials to withstand repeated mating cycles and harsh environmental conditions common in professional hardware deployments.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include the 305-064-521-278 and 305-064-521-504 from the same manufacturer family. These alternatives share identical electrical specifications and physical dimensions but may differ in specific ordering suffixes or packaging configurations. Always verify pin compatibility and mounting hole alignment before substituting components in existing designs.
