305-022-521-578

Edgeboard Connectors Overview

The EDAC Inc. 305-022-521-578 is a standard card edge connector from the 305 series, designed for panel mount and through-hole installation. It features a dual female configuration with 22 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) pitch and accepts board thicknesses ranging from 1.37 mm to 1.78 mm. Contacts are made of copper alloy with a gold finish, rated for 5 A continuous current. The housing is constructed from thermoplastic polyester, operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact mechanical dimensions and contact finish specifications. Ensure compatibility with target PCB thickness limits before procurement. Confirm availability status as distribution channels may vary. Cross-reference datasheet parameters for thermal and electrical ratings to match application requirements precisely.

Edgeboard Connectors Selection Notes

Select this component when a robust, high-current card edge solution is required for panel-mounted applications. The 3.96 mm pitch accommodates larger signal traces compared to finer pitches. Verify that the target circuit board thickness falls within the 1.37 mm to 1.78 mm acceptance range. Consider the 5 A rating per contact for power distribution needs within the assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations for diverse electronic interconnect needs. The 305-022 variant specifically provides a 22-position layout, balancing connectivity density with physical footprint constraints in modular electronic systems.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row count but different position numbers, such as 305-022-521-568 or 305-022-521-502. Verify mechanical fit and electrical ratings before substituting.
