305-018-556-578

Edgeboard Connectors Overview

The EDAC Inc. 305-018-556-578 is a standard card edge connector header featuring 18 positions with a 3.96 mm pitch. Designed for dual-edge mating, it utilizes gold plating on the contact area and tin plating with nickel underplating on the tails. The component supports a current rating of 5 amps and operates within a temperature range of -40°C to +105°C. It employs solder lug termination and is constructed from copper alloy contacts housed in thermoplastic insulation.

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required termination style and plating configuration. Confirm compatibility with the target PCB thickness and mounting requirements before procurement. Ensure supply chain sources provide authentic manufacturer documentation to guarantee compliance with electrical specifications and material standards.

Edgeboard Connectors Selection Notes

Select this model when a 18-position interface with a 3.96 mm pitch is required. The dual-edge configuration suits applications needing connection to both sides of a card. Consider the 5 amp current rating and thermal limits for environmental suitability. Verify that the solder lug termination aligns with the assembly process capabilities.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which offers various position counts and mounting options. The series is characterized by its standardized 3.96 mm pitch and robust construction suitable for demanding environments. It serves as a critical interconnect solution for modular electronic systems requiring reliable mechanical and electrical performance.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers within the same series for alternative position counts. Verify that substitute components maintain identical pitch, current ratings, and termination styles to ensure functional equivalence without redesigning the host circuit board.
