305-046-521-512

Edgeboard Connectors Overview

The EDAC Inc. 305-046-521-512 is a standard card edge connector from the 305 series, designed for dual female termination with 46 positions. It features a 0.156-inch (3.96mm) pitch and supports board thicknesses between 0.054 and 0.070 inches. The connector utilizes gold-plated copper alloy contacts with a 10.0µin thickness, rated for 5A continuous current and 1800VACrms insulation. It accepts both between-contact and in-contact polarizing keys, ensuring secure mating.

Edgeboard Connectors Procurement Notes

Verify RoHS3 compliance status prior to procurement, as environmental regulations vary by region. Confirm that the specific ordering suffix matches the required polarizing key compatibility and mounting style. Ensure the supplier provides official datasheets to validate the 5A current rating and voltage specifications against your system requirements.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with a 3.96mm pitch is required. The 46-position count suits applications needing moderate I/O density. Verify that the target PCB thickness falls within the 1.37mm to 1.78mm range to ensure proper contact engagement and mechanical fit.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of card edge connectors, which are characterized by their thermoplastic polyester construction and high-current capabilities. The series offers various position counts and mounting styles, serving as a versatile solution for panel mount and through-hole applications in demanding electronic environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-046-521-507 and 305-046-521-568. These alternatives share identical electrical ratings and physical dimensions but may differ in packaging or specific manufacturing lot details. Cross-reference the polarizing key requirements before substitution.
