305-072-555-578

Edgeboard Connectors Overview

The EDAC Inc. 305-072-555-578 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 72 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with copper alloy contacts featuring gold plating, it supports a continuous current rating of 5 A and withstands 1800 VACrms. The housing is made of green thermoplastic polyester, operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Low profile insulator body design for compact panel or PCB mounting applications
• Gold-plated copper alloy contacts ensure reliable electrical performance

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized module connections
• Test and measurement instrumentation with high-density signal routing

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact mechanical variations such as flange type or termination style. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Cross-reference the RoHS status and material composition requirements with project specifications to guarantee regulatory compliance. Confirm availability through authorized distributors as supply chain conditions may vary.

Edgeboard Connectors Selection Notes

Select this component when a 72-position dual-edge interface is required with a 3.96 mm pitch. The 5 A current rating and 1800 VACrms insulation voltage support high-power signal transmission. Consider the low-profile body and polarizing key acceptance if space constraints or precise board alignment are critical design factors. Verify that the operating temperature range meets the environmental demands of the intended application.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic designs. The series offers various position counts and mounting configurations to accommodate different board densities. The 305-072 variant specifically addresses high-pin-count applications requiring durable metal-to-metal contact interfaces.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-072-555-512 and 305-072-555-204. These alternatives share identical pin counts and spacing but may differ in termination style or mounting orientation. Verify mechanical fit and electrical ratings before substitution.
