305-084-500-578

Edgeboard Connectors Overview

The EDAC Inc. 305-084-500-578 is a standard card edge connector designed for dual-edge mating applications. It features 84 positions arranged in two rows with a pitch of 3.96 mm (0.156 inches). The component supports a PCB thickness of 1.57 mm and utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. Rated for 5 A current, it employs a solder eyelet termination style for secure panel mounting. The housing is constructed from green thermoplastic material, providing durability within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official documentation to confirm exact plating thickness, housing color, and termination style variations. Ensure compatibility with the target PCB stack-up and mating card dimensions before procurement. Cross-reference the RoHS status and lead-free requirements with current regulatory standards applicable to your region. Confirm that the panel mount orientation matches the system enclosure design constraints.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count dual-edge interface is required for standard thickness cards. The 3.96 mm pitch accommodates larger gauge traces compared to finer pitches. Verify that the 5 A current rating meets the power distribution needs of the application. Consider the thermal limits of the thermoplastic housing if the operating environment exceeds standard ambient temperatures. Ensure the solder eyelet termination method aligns with the available assembly processes.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides a range of position counts and termination options for various industrial and commercial applications. The 305 series is characterized by its consistent 3.96 mm pitch and durable construction suitable for repeated mating cycles. It serves as a reliable interconnection solution for modular electronic systems.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with matching pin counts and termination styles, such as 305-084-500-268 or 305-084-500-507, provided the specific suffix variations are verified. Ensure any replacement maintains the same 84-position count, dual-row configuration, and 3.96 mm pitch to guarantee mechanical fit.
