305-042-521-512

Edgeboard Connectors Overview

The EDAC Inc. 305-042-521-512 is a standard card edge connector from the 305 series, designed for panel mount installation with a vertical orientation. It features a dual female configuration with 42 positions arranged in two rows of 21 contacts each. The connector utilizes a 0.156-inch (3.96 mm) pitch and accepts board thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm). Contacts are made of copper alloy with gold plating and terminate via solder pins. The housing is constructed from green thermoplastic polyester, supporting an operating 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 and electrical specifications. Ensure compatibility with target PCB thickness within the 1.37 mm to 1.78 mm range. Confirm RoHS compliance status through current manufacturer datasheets prior to integration into regulated assemblies.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 42-position interface with a 3.96 mm pitch is required. The vertical panel mount style suits enclosures needing direct board insertion. Verify that the application environment remains within the specified -40°C to +105°C operational limits for optimal performance and longevity.

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 305-042 variant specifically addresses mid-range density needs with its 42-contact layout, balancing space efficiency with connection capacity in compact electronic assemblies.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts sharing the same pitch and row count. Verify mechanical dimensions and flange characteristics match existing panel cutouts before substitution.
