305-028-520-502

Edgeboard Connectors Overview

The EDAC Inc. 305-028-520-502 is a dual female card edge connector from the 305 series, designed for board edge and panel mount applications. It features 28 positions with a 0.156-inch (3.96mm) pitch across two rows. The connector utilizes copper alloy contacts with gold plating and a thermoplastic polyester insulator. Rated for 5A continuous current and 1800VACrms dielectric strength, it operates within a temperature range of -40°C to +105°C. The unit accepts between-contact and in-contact polarizing keys for secure alignment.

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 28-position configuration and dual female contact type. Confirm compatibility with the intended PCB thickness and polarizing key requirements. Ensure the supplier provides documentation confirming RoHS compliance and adherence to the manufacturer's specifications for the 305 series. Cross-reference the ordering guide to validate the suffix codes against the desired mounting style and termination method.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with a 0.156-inch pitch is required for panel-mounted applications. Consider the 5A current rating and 1800VACrms insulation capability for power and signal integrity needs. Evaluate the need for polarizing key acceptance to ensure mechanical stability during insertion. Compare against other series members if different position counts or mounting styles are necessary for the specific design constraints.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options while maintaining consistent electrical characteristics. The 305-028-520-502 variant specifically addresses applications requiring 28 positions with dual female contacts. It shares common design principles with other parts in the family, such as gold-plated contacts and thermoplastic insulation, ensuring interchangeability within system designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the 305 series include variants with different position counts, such as 305-028-520-501 or 305-028-520-504, provided the electrical and mechanical parameters remain compatible. Verify that any replacement maintains the same pitch, current rating, and polarizing key support. Consult the official ordering guide to confirm equivalent specifications before substitution.
